How Much Does It Cost To Install Underfloor Heating? UK Cost Guide 2025

June 28th, 2025

Underfloor heating is gaining popularity in UK homes due to its energy efficiency and the rising cost of heating bills. It can be up to 25% more efficient than traditional central heating systems with radiators, and up to 40% more efficient when combined with a heat pump. Conservative estimates suggest you could save up to £145 per year.

 

But how much does it cost to install underfloor heating? In this guide, we’ll break down the installation costs of underfloor heating in the UK for 2025, so you can weigh up the cost benefit versus the potential savings.

Before we begin, it’s important to draw a distinction between the two main types of underfloor heating: wet (water-based) and electric.

  • Wet underfloor heating – pipework connected to your central heating and boiler, usually installed by a qualified plumber or heating engineer.
  • Electric underfloor heating – uses electric mats or cables, installed and certified by a qualified electrician.

The complexity of installation depends on factors like the type of system, whether it’s a new build or retrofit, the floor construction, and the size of the area.

Additional Factors To Consider For Underfloor Heating Installs

When retrofitting underfloor heating, particularly wet systems, homeowners often underestimate the full cost. It’s not just about laying pipes or cables; the process often involves removing old radiators, capping off plumbing, repairing wall damage, fitting new flooring, and replacing skirting boards and architraves.

 

For new builds, the process is more straightforward; no demolitions or making good, just the cost of supplying and fitting the system into a new space.

 

Electric underfloor heating is also popular in upstairs bathrooms, where its thinner profile makes it easier to install without raising floor levels. It usually doesn’t require disturbing existing wall finishes.

Underfloor Heating Conversion Cost Calculations

In terms of build specification, BuildPartner gives you three broad options to choose from:

 

  • Basic spec is a basic finish; e.g., Leyland, Everest, Wickes.
  • Standard spec is a standard finish; e.g., Dulux, Hamilton, Slim Line.
  • Premium spec is a high-spec finish; e.g., Farrow & Ball, Fine Line, Siemens.

 

In this article, we’ve provided a breakdown of the cost of installing underfloor heating to a standard specification. In addition, we have provided three different benchmarks to show the range of pricing you can expect among different contractors. These are:

 

  • Low benchmark – smaller companies are generally lower cost but less specialised and with low project management function; good for low/mid-spec projects and tight budgets.
  • Mid benchmark – medium-sized companies offer a balanced mix of cost-effectiveness and specialisation; good for mid-range projects for effective execution within moderate budgets.
  • High benchmark – larger companies generally have a higher cost base but can handle a wide variety of specialist tasks; good for mid/high-spec projects and project management.

 

The specification and benchmark you choose will have a major impact on the overall cost, so it’s important to align them with both your budget and the level of finish you’re aiming for.

Cost Of Installing Wet Underfloor Heating - Retrofit

The table below shows the average cost of retrofitting wet underfloor heating for a 50m2 layout (i.e., ground floor):

Frequently Asked Questions About Installing Underfloor Heating

Here are some answers to frequently asked questions about installing underfloor heating.

What’s the difference between electric and wet underfloor heating?

Wet systems use hot water pumped through pipes and are cheaper to run but more complex to install. Electric systems use heated cables or mats, are easier to install, but cost more to run.

What's the best type of flooring to use with underfloor heating?

The best flooring for underfloor heating is one that conducts heat well and is stable with temperature changes. Tile and stone are great because they transfer heat efficiently and retain warmth. Engineered wood can also work well. Solid hardwood, however, can warp with changes in temperature and moisture.

Some vinyl and laminate options are suitable, but it’s always worth checking their compatibility with underfloor heating to prevent damage.

Will underfloor heating raise my floor height?

Installing underfloor heating will raise your floor height. Electric systems typically add around 15–30mm, while wet systems can add 30–70mm or more due to pipework and screed layers.

After installing, you may need to adjust or replace skirting boards and architraves to fit the new floor level, and there will often be extra work making good plaster and repainting affected walls.

Is underfloor heating expensive to run?

Electric underfloor heating typically uses 0.1–0.2 kWh per m² per hour, which costs around 3–6p per m² at current electricity rates.

Wet systems are more efficient, using about 0.05–0.1 kWh per m² per hour, and with gas at roughly 8p per kWh, the cost is closer to 0.4–0.8p per m².

That means wet underfloor heating is roughly 7 to 8 times cheaper to run than electric.

What’s the downside of underfloor heating?

With underfloor heating, you lose the option to hang clothes or towels on radiators to dry. You have no available warm surfaces for quick drying, something many of us rely on, particularly in colder months.

    Frequently Asked Questions About Garage Conversions

    Explore answers to frequently asked questions about garage conversions.

    Will a garage conversion add value to my home?

    A garage conversion can increase a property’s value, sometimes by 10–20%, particularly if it creates additional living space such as a bedroom or office. Due to the rise of working from home, many buyers are now looking for exclusive office space.

    In areas where off-street parking is limited, some buyers appreciate the security a garage offers. But if the property already has a driveway, the garage may surplus to requirements.

    So a conversion can make far better use of the existing space, turning what might otherwise become a dumping ground for old boxes into a functional room.

    Do I need building regulations approval for a garage conversion?

    Building control must inspect and sign off on the project, which is usually handled by your local authority to ensure that the work meets safety and structural standards.

    To convert a garage into living space, you don’t need planning permission as long as the work is internal and doesn’t involve enlarging the structure.

    What types of rooms can a garage be converted into?

    You can turn a garage into all sorts of useful spaces, depending on what you need. Popular choices include an extra bedroom, home office, playroom, gym, utility room, living room, or even a kitchen or bathroom.

    Some options are pretty straightforward, like a bedroom or office, but if you plan to put in a kitchen or bathroom, the costs will be higher, since you’ll need to factor in the cost of plumbing, electrical work, and appliances.

      Cost Comparison: Timber Frame vs Traditional Brick and Block Construction

      Cost Comparison: Timber Frame vs Traditional Brick and Block Construction
      Building Costs23 June 2025

      Cost Comparison: Timber Frame vs Traditional Brick and Block Construction

      May 28th, 2025

      Most houses in the UK are still built with brick, but there is a growing trend towards timber due to its environmental benefits and build efficiency, with around 23% of new homes built being with timber and a whopping 85% in Scotland!

       

      In addition, the UK Government has published a roadmap that outlines efforts to increase timber use in construction, aiming to meet net-zero targets. So, with a growing trend, important to understand cost implications.

       

      In this guide, we’ll break down the typical costs of building a timber-frame home versus a brick/block home. We’ll look at the cost of building by region and review average costs per square metre to help you budget accurately.

      Brick & Timber Frame Cost Calculations

      In terms of build specification, BuildPartner gives you three broad options to choose from:

       

      • Basic spec is a basic finish; e.g., Leyland, Everest, Wickes.
      • Standard spec is a standard finish; e.g., Dulux, Hamilton, Slim Line.
      • Premium spec is a high-spec finish; e.g., Farrow & Ball, Fine Line, Siemens.

       

      In this article, we’ve provided a breakdown of the cost of converting a garage to a standard specification. In addition, we have provided three different benchmarks to show the range of pricing you can expect among different contractors. These are:

       

      • Low benchmark – smaller companies are generally lower cost but less specialised and with low project management function; good for low/mid-spec projects and tight budgets.
      • Mid benchmark – medium-sized companies offer a balanced mix of cost-effectiveness and specialisation; good for mid-range projects for effective execution within moderate budgets.
      • High benchmark – larger companies generally have a higher cost base but can handle a wide variety of specialist tasks; good for mid/high-spec projects and project management.

       

      The costs in this guide are based on building a two-storey home comprising 95m². The figures cover the cost of constructing the external shell only and exclude internal finishes, such as kitchens, bathrooms, and flooring.

      Here are the key takeaways from the cost comparison between timber and brick/block construction:

      • Brick/block spends £48,999 (20.5%) on external wall structure—almost double the £25,972 (11.1%) spent in the timber build. However, timber allocates more to internal wall components and finishes.
      • No budget is allocated for brick/block for external wall finishes, while timber includes £21,020 for finishes. The brick façade is structural and finish in one, while timber needs cladding added separately.
      • Timber shows higher costs in project management (£18,532 vs £15,395) and floor structure (£18,130 vs £14,596) due to the complexity of assembling prefabricated components on site.
      • Several elements, such as scaffolding, roof structure, ceiling lining, access points, and fascias, have the exact same costs, showing standardisation across both methods for these elements.
      • Timber spends slightly more on roof coverings, floor lining, and internal wall structure, indicating a focus on finish quality and extra insulation needs.

       

      Average Cost Of Building With Brick & Timber

      So, what’s the average cost difference of building with brick/block versus timber in the UK? Based on building a two-storey property comprising 95m2, it costs on average (when using a mid-benchmark contractor):

      • Two-storey timber-frame build: £218,141, or £2,316 per square metre.
      • Two-storey brick/block build: £215,809, or £2,291 per square metre.

      So, overall in the housing sector, timber and masonry builds show near price parity once all construction factors are taken into account.

      Frequently Asked Questions About Building With Brick & Timber

      Explore answers to frequently asked questions about building with brick/block and timber.

      What are the benefits of building with brick and timber?

      Brick has a higher thermal mass, meaning it retains heat during the day and releases it slowly, which helps keep your home warm in winter and cooler in summer. It’s also great at blocking out noise, which is great if you live near a road or in a busy area. In addition, brick doesn’t need much looking after and tends to outlast alternatives like timber cladding.

      Timber is much better for the environment, with a much lower carbon footprint than brick. It also offers lots of design options, from precise geometrical shells to a variety of looks including clean, contemporary, rustic, traditional, and weathered. It can be quicker to work with, especially if you’re using prefabricated sections.

      Are there any fire safety concerns when using timber frames?

      Timber is a combustible material, whereas brick and block are non-combustible and therefore fire-resistant. So, fire safety must be carefully planned. Quite often, engineered timber is used, which chars predictably and maintains structural integrity longer when exposed to heat and flames.

      Building Regulations typically require additional fire safety measures such as fire-rated cladding, treated timber, and internal fire doors. While sprinklers are only mandared on domestic buildings over 4 storeys or in Wales for new-builds, it’s still a good idea to install them.

      How durable is brick and timber construction?

      Brick is extremely durable and can last over 100 years with minimal maintenance; it’s also resistant to fire, pests (insects such as woodlice), and weather.

      On average, you can expect to replace timber cladding every 20 to 40 years depending on the climate and the type of wood (hardwoods like oak typically last longer than softwoods like pine). If the property is in a damp, coastal, or harsh climate, the timber cladding is likely to need replacing sooner due to exposure to moisture, salt, and weathering.

      Why does timber need careful storage on site?

      Timber needs to be carefully stored on site unlike brick/block. Once it’s delivered, you’ve got to keep it dry and properly protected. Too much moisture causes warping (especially without airflow), and if it’s not stacked right, it can bend and get scratched.

        How Much Does A Bathroom Renovation Cost In 2025? UK Cost Breakdown

        April 28th, 2025

        From tiling and plumbing to fixtures and finishes, the costs to renovate a bathroom renovation vary widely depending on the size of the space and the specifications of the project. This guide breaks down typical bathroom renovation costs in the UK so that you can plan your budget with no nasty surprises.

         

        We look at the cost of fully renovating three common bathroom types: a main bathroom, an ensuite, and a WC. We also break down average renovation costs by UK region and per square metre. One notable exclusion is underfloor heating, as it’s not always essential.

        Bathroom Renovation Cost Calculations

        In terms of build specification, BuildPartner gives you three broad options to choose from:

         

        • Basic spec is a basic finish; e.g., Leyland, Everest, Wickes.
        • Standard spec is a standard finish; e.g., Dulux, Hamilton, Slim Line.
        • Premium spec is a high-spec finish; e.g., Farrow & Ball, Fine Line, Siemens.

         

        In this article, we provide a breakdown of the cost of renovating a bathroom for all three specifications. In addition to this, we also provide three different benchmarks to show the range of pricing you can expect among different contractors. These are:

         

        • Low benchmark – smaller companies are generally lower cost but less specialised and with low project management function; good for low/mid-spec projects and tight budgets.
        • Mid benchmark – medium-sized companies offer a balanced mix of cost-effectiveness and specialisation; good for mid-range projects for effective execution within moderate budgets.
        • High benchmark – larger companies generally have a higher cost base but can handle a wide variety of specialist tasks; good for mid/high-spec projects and project management.

        Average Cost Of A Bathroom Renovation (Standard Spec)

        The table below shows the average cost of renovating a bathroom in the UK to a standard spec:

        Frequently Asked Questions About Bathroom Renovation Costs

        Here are some frequently asked questions about bathroom renovation costs.

        Does changing the bathroom layout increase the cost?

        Any deviation from the existing layout pushes up labour costs and extends the schedule. For example, moving a toilet typically involves relocating the soil pipe, which may mean breaking up floors or boxing in new pipe runs.

        Similarly, relocating a shower or bath means installing new hot and cold feeds, as well as drainage. Not only that, but structural changes, like moving a wall or window, bring in additional trades such as joiners and bricklayers.

        How can I keep costs low when renovating a bathroom?

        There are plenty of ways to keep costs under control. The biggest saver is sticking to the existing layout. Keeping toilets, showers, and basins in the same position avoids the need to move pipework.

        Also, you don’t need to tile every wall — just the wet areas and a splashback behind the basin. The rest can be plastered and painted with good-quality anti-condensation paint.

        If the existing toilet or basin is in decent condition, you might be able to keep it and just replace the taps or seat. With a bit of effort, ceramic surfaces clean up nicely.

        How much space do I need for an ensuite?

        You can fit a compact ensuite into as little as 1.5m x 1m using space-saving fixtures like corner basins and sliding doors. It won’t be spacious, but it’ll be functional. A typical ensuite is usually around 1.5m x 2.5m (3.75m²), giving enough space for a toilet, basin, and shower.

          If you’re planning to remodel your existing space to make way for an open-plan kitchen diner, the total cost can vary widely depending on factors such as the specification, local labour rates, structural work required, and the quality of materials you choose.

          In this article, we cover the costs involved in converting your existing kitchen and living room, typically by downsizing the living space, to create a larger, open-plan kitchen diner. From knocking down walls and moving utilities to choosing your units and finishes, we’ll break down what you can expect to spend.

          We’ll take a look at the cost of converting a kitchen diner by region, covering London, North England, Scotland, Wales, and Northern Ireland. We’ll also review average costs per square metre to help you budget accurately and avoid overspending.

          Kitchen Diner Cost Calculations

          The calculations in this guide assume that the existing structure remains in place, with no additional extensions. The cost breakdown includes a full kitchen remodel with all-new appliances—hob, electric oven, fridge, freezer, dishwasher, washing machine, and extractor fan.

          It also includes the installation of bifold doors to open up the space between inside and outside for a blended dining experience.

          In terms of build specification, BuildPartner gives you three broad options to choose from:

          • Basic spec is a basic finish; e.g., Leyland, Everest, Wickes.
          • Standard spec is a standard finish; e.g., Dulux, Hamilton, Slim Line.
          • Premium spec is a high-spec finish; e.g., Farrow & Ball, Fine Line, Siemens.

          In this article, we’ve provided a breakdown of the cost of converting to a kitchen diner for all three specifications. In addition to this, we have also provided three different benchmarks to show the range of pricing you can expect among different contractors. These are:

          • Low benchmark – smaller companies are generally lower cost but less specialised and with low project management function; good for low/mid-spec projects and tight budgets.
          • Mid benchmark – medium-sized companies offer a balanced mix of cost-effectiveness and specialisation; good for mid-range projects for effective execution within moderate budgets.
          • High benchmark – larger companies generally have a higher cost base but can handle a wide variety of specialist tasks; good for mid/high-spec projects and project management.

          Frequently Asked Questions About Kitchen Diner Conversions

          Here are some frequently asked questions about the costs of converting a kitchen diner.

          How long does it take to convert a kitchen diner?

          Converting to a kitchen diner takes an average of 3.75 weeks, with an average of two tradespeople carrying out the work. Here’s a rough breakdown of the project:

          • Demolitions begin in Week 1 and wrap up by early Week 2.
          • Windows and doors are installed in Week 1, followed by internal doors and frames.
          • Drainage and pipework start in Week 2, overlapping with heating and cooling.
          • Wired appliances are set up in Week 3, alongside ceiling and wall preparation.
          • Worktops and kitchen appliances are installed in Week 4.
          • Decoration begins in Week 4 and finishes in Week 5, marking the project’s end.

          Can I knock through a wall to open up space for a kitchen diner?

          Yes, if the wall isn’t load-bearing, it’s usually straightforward. If it’s structural, you’ll need a steel beam (RSJ—rolled steel joist) and Building Regulations approval.

          How do I know if a wall is load-bearing?

          Here are a few signs that a wall might be load-bearing:

          • It feels solid (brick or block rather than stud and plasterboard).
          • It’s located in the centre of the house, supporting joists or beams above.
          • It runs perpendicular to floor joists.
          • There’s another wall or beam directly above it on the upper floor.
          • It aligns with beams or support structures in the loft or basement.

          The only reliable way to be sure is to consult an experienced builder or structural engineer. They can assess the property’s structure and confirm what support is needed if you plan to remove it.

            How Much Does It Cost To Remodel A House In 2025? A UK Guide

            March 28th, 2025

            When remodelling a house, costs can vary widely depending on the scope of work. The first thing to be mindful of is not to confuse remodelling with renovation. A renovation refreshes and restores existing rooms without altering their layout, whereas a remodel involves changing the internal structure—for example, removing walls to create an open-plan living, kitchen, and dining area.

            Naturally, remodelling is more expensive. So, how much does it cost to remodel a house in 2025? In this article, we cover the costs of remodelling a 3-bedroom house (90m2 – the average size) comprising the following rooms:

            • Kitchen-living-dining room
            • Downstairs WC
            • Boiler cupboard
            • Cloakroom
            • Entrance hall
            • 3x bedrooms
            • Bathroom
            • En-suite

            The calculations in this guide assume the existing shell remains, with no extensions.

            We’ll take a look at the cost of remodelling a house by region, covering London, North England, Scotland, Wales, and Northern Ireland. We’ll also review average costs per square metre to help you budget accurately and avoid overspending.

            Remodelling A House Cost Calculations

            In terms of build specification, BuildPartner gives you three broad options to choose from:

            • Basic spec is a basic finish; e.g., Leyland, Everest, Wickes.
            • Standard spec is a standard finish; e.g., Dulux, Hamilton, Slim Line.
            • Premium spec is a high-spec finish; e.g., Farrow & Ball, Fine Line, Siemens.

            In this article, we’ve provided a breakdown of the cost of remodelling for all three specifications.

            In addition to this, we have also provided three different benchmarks to show the range you can expect amongst different contractors. These are:

            • Mid benchmark – medium-sized companies offer a balanced mix of cost-effectiveness and specialisation; good for mid-range projects for effective execution within moderate budgets.
            • High benchmark – larger companies generally have a higher cost base but can handle a wide variety of specialist tasks; good for mid/high-spec projects and project management.

            • Basic spec: £132,483, or £1,485 per square metre. 
            • Standard spec: £152,124, or £1,705 per square metre. 
            • Premium spec: £187,978, or £2,089 per square metre.

            The costs in this guide exclude extensions. If you’re planning to build an extension, you should factor in approximately £2,900 per square metre for a ground-floor extension, and £2,400 for a double-storey rear extension.

            Frequently Asked Questions About Remodelling A House

            Here are some frequently asked questions about remodelling a house.

            How long does it take to remodel a house?

            Remodelling a three-bed house takes an average of 20.9 weeks with an average of two tradespeople carrying out the work. Here’s a rough breakdown of the project:

            • Demolitions take place early, lasting about five weeks.
            • External and internal wall structures are built simultaneously.
            • Windows and doors are installed, followed by internal doors and frames.
            • Drainage and pipework progress alongside heating and cooling system installations.
            • Electrical work, including wiring, fuse boards, and appliances, occurs mid-project.
            • Ceiling and wall preparation, flooring, and kitchen installations follow. 
            • Joinery, decoration, and fixtures and fittings finalise the remodel in the last weeks.

            As ever, progress heavily depends on the alignment of tradesmen at key stages. For instance, delays in external and internal wall construction in weeks 5–7 can push back heating and electrical work scheduled for the following weeks.

            What is the difference between remodelling and renovating a house?

            Remodelling and renovating are often used interchangeably, but they’re not the same. Renovating involves restoring or updating existing features, whereas remodelling alters the structure or floor plan—for example, removing walls to create an open-plan living, kitchen, and dining area.

            Should I move out when remodelling a house?

            It’s a good idea to move out during a home remodel, especially for larger projects. The disruption from contractors needing access at awkward times, the dust and debris, and the noise make for uncomfortable living. Additionally, at certain times, you’ll need to switch off the electricity to carry out work, which will leave you without power (and wi-fi!). 

            If plumbers are working, you’ll have no access to washing, cooking, or heating, which can be particularly challenging during the winter. Then, there are also safety concerns with power tools and other hazards being left out, especially if you have young children. It’s better to find alternative accommodation.

              How Much Does It Cost To Build A Bungalow In 2025? A UK Guide

              How Much Does It Cost To Build A Bungalow In 2025? A UK Guide

              March 28th, 2025

              There is a distinct shortage of bungalows in the UK, and the average price has tripled in the last 25 years, which is further exacerbated by a lack of new builds. In 1996, for example, 7% of new-build properties were bungalows, according to the National House Building Council; today, that figure has slowed to just 1%.

               

              That drop can be largely attributed due to a shift in planning policy—there is a much greater focus on sustainability by making the best use of sites and reducing footprint (often through building larger dwellings and more storeys). However, while many developers focus on large-scale projects, building a bungalow remains an attractive option for self-builders or individual projects.

               

              So, how much does it cost to build a bungalow?

               

              Naturally, building costs vary by size, type, and complexity, so in this article, we’ll cover the cost of building a bungalow across various regions in the UK.

               

              To give you an accurate view, we’ll compare the cost of building three different types of bungalows:

               

              • Two-bedroom bungalow (90m2)
              • Three-bedroom bungalow (100m2)
              • Three-bedroom bungalow with garage and driveway (125m2)

               

              We’ll delve into the cost breakdown for each bungalow by region. We’ll also review the average costs per sq metre, to ensure your project is accurately costed and to minimise overspend.

              How Bungalow Construction Has Evolved In The UK

              Historically, bungalows in the UK were often built as affordable homes using simple timber frame construction and trussed rafter roofs. This allowed for quick, low-cost builds.

              However, with bungalows now in high demand—especially among downsizers and those seeking future-proof homes—developers are turning to more robust materials and modern construction techniques, such as insulated concrete formwork (ICF), structural insulated panels (SIPs), or high-spec masonry builds.

              These methods improve energy efficiency, longevity, and design flexibility, but they can also push up the cost per square metre, meaning today’s bungalows are often anything but cheap.

              Building A Bungalow Construction Cost Calculations

              In terms of build specification, BuildPartner gives you three broad options to choose from:

               

              • Low spec is a basic finish; e.g., Leyland, Everest, Wickes.
              • Standard spec is a standard finish; e.g., Dulux, Hamilton, Slim Line.
              • Premium spec is a high-spec finish; e.g., Farrow & Ball, Fine Line, Siemens.

               

              To keep this comparison simple, we have chosen standard spec in all our cost estimations. In addition to this, we have also provided three different benchmarks to show the range you can expect amongst different contractors. These are:

               

              • Low benchmark – smaller companies are generally lower cost but less specialised and with low project management function; good for low/mid-spec projects and tight budgets.
              • Mid benchmark – medium-sized companies offer a balanced mix of cost-effectiveness and specialisation; good for mid-range projects for effective execution within moderate budgets.
              • High benchmark – larger companies generally have a higher cost base but can handle a wide variety of specialist tasks; good for mid/high-spec projects and project management.

              Frequently Asked Questions About Building A Bungalow

              Here are some frequently asked questions about building a bungalow.

              How long does it take to build a bungalow?

              Building a three-bed bungalow (with a garage) takes an average of 26.85 weeks with an average of two tradespeople carrying out the work. The process begins with preliminaries, demolitions, and foundation work in the first six weeks, followed by the construction of structural elements, including steel supports, external walls, and roofing, which continues until approximately week 10. 

              By weeks 9 to 16, windows, doors, drainage, heating, and electrical systems are installed. In the final stages, from weeks 16 to 27, work on joinery, decoration, fixtures, and external elements takes place.

               

              What is the ideal size for a bungalow?

              A typical two-bedroom bungalow is around 60–80m², while a three-bedroom design ranges from 90–120m². Adding a single garage typically increases the size by 15–20m², while a double garage adds approximately 30–40m², providing enough space for two cars and extra storage.

              Do bungalows hold their value?

              Demand to downsize is increasing, and many bungalows that are put on the market are snapped up quickly. Regency Living found that bungalows currently account for just one in 10 homes listed for sale. Regional data shows the varying availability of bungalows:

              • London: 2%
              • South West: 13%
              • Yorkshire: 12%

              Despite their relatively small share of the housing market, the demand for bungalows remains high. The average price soared for three consecutive years but declined slightly in the most recent calendar year, as reported by Statista, and since the year 2000, bungalow prices have tripled.

                How Much Does It Cost To Build A Porch In 2025? A UK Guide

                How Much Does It Cost To Build A Porch In 2025? A UK Guide

                February 28th, 2025

                Building a porch is a great way to enhance your home’s kerb appeal, add extra storage, and improve insulation (heat loss through windows and doors accounts for 20–30% of the whole heat loss of house). A porch also improves home security by adding an extra layer of protection.

                 

                But costs can vary widely depending on size, materials, and whether the structure is enclosed or open. In this guide, we’ll break down the key factors affecting porch costs in the UK, comparing four different types of porches:

                 

                • Brick porch – constructed with bricks.
                • Rendered porch – built with blocks and a rendered finish.
                • Timber porch (enclosed) – made primarily from wood.
                • Open porch – without enclosed walls, and offering an external shelter.

                 

                Here's a breakdown of the costs for different types of porches, so you can determine which option best suits your project.

                 

                Building A Porch Construction Cost Calculations

                 

                Our cost comparisons are based on a gross external floor area (GEFA) of 3m². The only exception is the open porch, which is based on a GEFA of 2m2. Since an open porch is primarily an aesthetic shelter, a smaller size better reflects its typical usage.

                 

                In terms of build specification BuildPartner pricing tool gives you three broad options (which can be revised by item at a later point):

                 

                • Low spec is a basic finish; e.g. Leyland, Everest, Wickes.
                • Mid spec is a standard finish; e.g. Dulux, Hamilton, Slim Line.
                • High spec is a high-spec finish; e.g. Farrow & Ball, Fine Line, Siemens.

                 

                To keep this comparison simple, we have chosen mid spec in all our cost estimations. In addition to this, we have also provided three different benchmarks to show the range you can expect amongst different contractors. These are:

                Summary Of The Average Cost To Build A Porch

                So, how much does it cost to build a new porch in the UK? That depends largely on where you are building. If you’re building a porch in London, it will cost you an average of 13% more.

                Based on the four different types of porches covered in this article, you can expect building a porch to cost on average (when using a mid-benchmark contractor):

                • Brick porch – £8,391, or £2,821 per square metre
                • Timber porch – £6,954, or £2,338 per square metre
                • Rendered porch – £5,818, or £1,939 per square metre
                • Open porch – £3,807, or £1,920 per square metre

                Frequently Asked Questions About Building A Porch

                Here are some frequently asked questions about building a porch.

                Can a porch prevent heat loss in my home?

                Building a porch improves energy efficiency by creating an air buffer that traps cold air before it reaches your main entrance. It also acts as a thermal barrier, providing an additional layer of protection against the elements. 

                The most energy-efficient porches are made from brick and timber, which benefit from greater thermal mass to regulate temperature. uPVC is less efficient without high-quality glazing and seals.

                Does adding a porch increase security and reduce the risk of burglary?

                If you keep your existing front door, the porch effectively provides double security—a potential intruder would have to get past both the porch and your door to gain entry. This added barrier can significantly deter burglars. 

                Is a porch good for storage?

                A porch is great for storage because it can act as a cloakroom or boot room, providing space for coats, boots, bags, and outdoor gear. No more coats draped over chairs or shoes scattered around the hallway—it's a purposeful space for your outdoor items.

                What are the downsides of getting a uPVC porch?

                uPVC porches are generally less energy-efficient and can allow more heat to escape. Additionally, while uPVC porches can last 20 to 30 years, they can become brittle, yellow, or fade with age, especially when exposed to harsh weather conditions. They aren’t as visually appealing as natural materials like brick or timber.

                  How Much Does It Cost To Build A Garage In 2025? A UK Guide

                  January 25th, 2025

                  The cost of building a garage continues to be influenced by rising material prices, labour rates, and regional variations across the UK. Whether you’re looking to build a small single garage or a spacious double garage, understanding the costs involved is essential to avoid cost overruns.

                   

                  In this guide, we’ll provide a detailed comparison of four popular garage types: single garage with a flat roof, single garage with a pitched roof, double garage with a flat roof, and double garage with a pitched roof. This guide also includes regional rate comparisons across the UK, along with building costs per square metre.

                   

                  Building A Garage Construction Cost Calculations

                   
                  In our calculations, we applied a consistent methodology across different regions. The cost comparisons assume the garage is an extension to an existing dwelling, not a new detached structure. These cost excludes the installation of appliances and EV chargers.

                   

                  The typical sizes of garages in the UK are:

                   

                  • Single – 10 x 18 feet (3m × 5.5m, with a gross external area of 16.5m2)
                  • Double – 18 x 18 feet (5.5m × 6m, with a gross external area of 33m2)

                   

                  We have used both of these measurements to calculate the costs in this article.

                   

                  In terms of build specification when using our BuildPartner pricing tool, our pricing calculator gives you three broad options (which can be revised by item at a later point):

                   

                  • Low spec is a basic finish; e.g. Leyland, Everest, Wickes.
                  • Standard spec is a standard finish; e.g. Dulux, Hamilton, Slim Line.
                  • Premium spec is a high-spec finish; e.g. Farrow & Ball, Fine Line, Siemens.

                   

                  To keep this comparison simple, we have chosen standard spec in all our cost estimations. 

                   

                  In addition to this, we have also provided three different benchmarks to show the range you can expect amongst different contractors. These are:

                  • Low benchmark – smaller companies are generally lower cost but less specialised and with low project management function; good for low/mid-spec projects and tight budgets.
                  • Mid benchmark – medium-sized companies offer a balanced mix of cost-effectiveness and specialisation; good for mid-range projects for effective execution within moderate budgets.
                  • High benchmark – larger companies generally have a higher cost base but can handle a wide variety of specialist tasks; good for mid/high-spec projects and project management.

                   

                  In short, contractor pricing varies due to factors such as expertise, location, and project intricacies.

                  Frequently Asked Questions About The Cost To Build A Garage

                   
                  Here are answers to common questions about the cost of building a garage.

                  What additional costs should I budget for when building a garage?

                   
                  When building a garage, consider the costs of adding an electric vehicle (EV) charger, which typically ranges from £800–£1,500. Upgrading or paving the driveway to provide smooth access can cost anywhere between £1,000–£5,000, depending on the materials used. Additionally, if you need to adjust access to a public road, installing a dropped kerb can cost £1,000–£2,500. 

                  Do I need planning permission to build a garage in the UK?

                   
                  In the UK, garages under 30 square metres often fall under permitted development and require no planning permission if they meet specific criteria (e.g., height limits, no sleeping accommodation).  
                   
                  Boundary rules (e.g., Party Wall Act) may apply if the garage is built close to property lines. Additionally, restrictions for conservation areas or listed properties may require further permissions. Always check with your local planning authority for specific requirements.
                   
                  For more information, see our related article which covers planning permission.
                   

                  Will building a garage affect council tax band?

                   
                  While adding a garage doesn’t automatically increase your council tax, your local council or the VOA  (Valuation Office Agency in England and Wales, or the Scottish Assessors in Scotland) might reassess your property after the addition—although this is extremely rare. 
                   

                  What is the average daily rate for builders in the UK?

                   
                  Builders typically charge £150 to £300 per day, while specialist trades (electricians, plumbers) may charge £200 to £400 per day. Check out our latest article on our blog for more information about the rates of different trades by region.

                    How Much Does It Cost To Build An Extension In 2025? A UK Guide

                    January 30th, 2025

                    Building an extension is an excellent way to increase living space and add value to your home, particularly when the alternative—moving house—is so expensive. However, costs vary significantly depending on factors such as the type of extension, location, materials used, and the complexity of the project. 

                    In this guide, we break down the average costs of building a ground-floor and double-storey extension to help you understand what to expect when planning your construction project. We provide the average costs by region and also a breakdown of breakdown by project stage and room type.

                    Building An Extension In The UK

                    In our calculations, the costs of building an extension are based on the following:

                    • The roof of the extension is pitched, not flat.
                    • The extension is constructed out of brick/block, not a timber frame.

                    Also, the rooms in the calculation for the extension comprise:

                    • 20m² single-storey rear extension: dining room, utility room, WC.
                    • 40m² double-storey rear extension: dining room, utility room, WC, two bedrooms, an en-suite bathroom, storage room, small landing.

                    Which rooms you choose ultimately affects the overall cost of the extension. For instance, if we were adding a kitchen instead of a dining room, we would need to factor in the cost of fitting a kitchen and the appliances.

                    Calculations reflect the cost of fitting out the new rooms only. They do not include the remodelling of existing rooms or changes to the layout.

                    In terms of build specification, our pricing calculator has three options:

                    • Low spec is a basic finish; e.g. Leyland, Everest, Wickes.
                    • Mid spec is a standard finish; e.g. Dulux, Hamilton, Slim Line.
                    • High spec is a high-spec finish; e.g. Farrow & Ball, Fine Line, Siemens.

                    For the purposes of these extensions, we reviewed the costs for standard specification. Then, for each specification, we’ve provided a range of prices to reflect the varying types of contractors:

                    • Low benchmark – smaller companies are generally lower cost but less specialised and with low project management function; good for low/mid-spec projects and tight budgets.
                    • Mid benchmark – medium-sized companies offer a balanced mix of cost-effectiveness and specialisation; good for mid-range projects for effective execution within moderate budgets.
                    • High benchmark – larger companies generally have a higher cost base but can handle a wide variety of specialist tasks; good for mid/high-spec projects and project management.

                    FAQs About Building An Extension In The UK

                     

                    Here are some frequently asked questions about building extensions in the UK.

                     

                    What are the different types of extensions?

                    Common ground-floor extensions include rear, side, double-storey, and wraparound. A rear extension expands the back, while a side extension adds space to the side of the property. A double-storey extension increases space both upstairs and downstairs, and a wraparound extension combines rear and side extensions for a larger, open-plan space.

                    Do I need planning permission for an extension?

                    There are many variables to assess to determine if planning permission is needed when building an extension. For example, you need planning permission if your single-storey rear extension is higher than four metres or extends beyond the rear of the “original house” by more than six metres.

                     

                    In many cases, extensions fall under permitted development rights. Find out more about planning permission in our guide here.

                     

                    Do I need a Party Wall Agreement?

                    If your extension affects a shared wall or boundary with a neighbour, the Party Wall Act 1996 requires you to serve notice and potentially obtain their consent.
