Barn conversions are rising in popularity in the UK, driven by the favourable planning rules and a growing demand for sustainable, character-rich properties for both the residential and holiday rental markets. But how much does it cost to convert a barn? And what is the cost per square metre?

In this article, we cover the costs of barn conversions for a single-storey and a double-storey conversion. We also bring you up to speed on UK planning rules and the differences between classifications of barn conversions in the UK.

Barn Conversion Cost Considerations

The costs in this guide assume that the barn conversions do not require new roofs or walls.

Since barn conversions vary in size and there is very limited data on the average size, we based our calculations on a ballpark figure of 80m2 of floor space per storey (160m2 for a double-storey conversion).

• The double-storey barn conversion comprises four bedrooms, one en-suite, a bathroom, a WC, a kitchen, a living room, and a cloakroom.
• The single-storey barn conversion comprises three bedrooms, a bathroom, a WC, a kitchen, and a living room.

We also provide a breakdown per square metre so you can work out the costs for your project – if you happen to know the dimensions.

In the cost breakdown provided later, you’ll notice a disproportionate amount of the cost is attributed to foundations and substructure. The main reason for this is that most barns have shallow foundations, which are unsuitable for modern residential standards. 

Therefore, underpinning – the technique that stabilises existing foundations – accounts for a significant part of the cost. 

Build Specifications and Supplier Benchmarks 

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

 

• 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.

 

For this particular cost breakdown, we have selected standard spec. In addition, 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.

Do I need planning permission to convert a barn?

In most cases, you don’t need to submit a full planning application to convert a barn, but it’s a good idea to obtain something called a lawful development certificate.

Despite the name, it’s actually not a legal requirement, but it does protect you in the event of planning policies change. Without one, if your conversion is later deemed to be unlawful, this could result in fines or, worse, the demolition of your project.

To get started, you need to submit your designs by giving “prior notification” to your local authority. They’ll review your designs to ensure you’re within your permitted development rights and a host of other factors such as transport, noise, and flood risk.

It can take anywhere between two to three months to gain approval.

If you plan on extending your barn, however, you will need to apply for planning permission.

Barn Conversion Classifications – UK

In the UK, barn conversions have three main classifications (Q, R, and S). Here’s what each covers:

Class Q – Agricultural to Residential

Class Q allows the conversion of agricultural buildings, such as barns, into residential homes without full planning permission. 

To meet the criteria for Class Q, the barn must:

• Have been used solely for agricultural purposes before 20 March 2013.
• Be no greater than 1,000m2 of floor space.

If a barn conversion falls under Class Q, up to ten separate dwellings (previously five) can be created, providing that the maximum size of a dwelling is no greater than 150 square metres. In addition, structural alterations must not extend beyond the original footprint of the building.

Class R and Class S – Agricultural to Flexible Commercial Use

Class R permits the change of use from agricultural buildings to a range of commercial uses, such as retail, offices, restaurants, hotels, or leisure facilities.

Class S allows the conversion of agricultural buildings into state-funded schools or registered nurseries (education facilities).

To meet the criteria for Class R and S, the barn must:

• Have been used solely for agricultural purposes before 3 July 2012.
• Be no greater than 1,000m2 of floor space.

Also, the location must not be within protected areas, such as national parks or areas of outstanding natural beauty (AONB).

Proposed Legislation Changes

The previous Conservative government proposed plans to relax rules on barn conversions in national parks and AONBs. These were widely condemned by several key figures, including Kevin Bishop, the CEO of Dartmoor National Park Authority, who said:

“The ability to convert any agricultural barn to an open market house would cause untold damage to our landscapes and do nothing to support the provision of affordable housing.”

The new Labour government has yet to comment on these plans.

Average Cost To Convert A Barn In The UK

So, how much does a barn conversion cost in the UK? Based on the two types covered in this article, you can expect that converting a barn to cost on average (when using a mid-benchmark contractor):

• Single-storey barn – £218,038, or £2,751 per sq metre.
• Double-storey barn – £289,581, or £1,828 per sq metre. 

Depending on the specifications, the cost of the work for a barn conversion would range between £188,858 and £370,785. 

Please remember that these costs do not include VAT, and there may be other additional costs, such as obtaining planning permission, conducting structural surveys, making unexpected repairs, and completing custom finishes.

This figure covers construction expenses like materials and labour but does not include the cost of land.

However, a lack of land, a sluggish planning system, and infrastructure challenges mean that developers are looking to expand elsewhere in the UK. But with “incredible scarcity, property prices and rents are going to continue to go up,” says Conor Mulligan of Lagan Homes.

Frequently Asked Questions About House Building In Northern Ireland

Here are a few questions that provide extra insight into the cost of building a house in Northern Ireland.

What is the average house price in Northern Ireland?

According to the Northern Ireland House Price Index, the average house price in Northern Ireland is £185,025. The average ranges from £163,836 in Derry City and Strabane to £215,464 in Lisburn and Castlereagh. The average price in the capital, Belfast, is £168,054.

Why has housebuilding in Northern Ireland hit a 60-year low?

The biggest issue relates to its infrastructure: Northern Ireland’s water capacity constraints. Plans for an estimated 19,000 homes in 23 towns are being held up due to an outdated and at-capacity sewage network. Whether development is allowed varies by area; in some places, it is permitted, in others, it may be allowed at additional cost, and in certain locations, it’s all but prohibited.

Housebuilding costs are soaring, and England is no exception. The number one challenge, according to the Chief Executive of Barratt Homes, is the shortage of skilled tradespeople. Couple that with inflation for materials, and you have a perfect storm for driving up construction costs, adding complexity to an already challenging housing market in England.

• 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.

The costs associated with the projects in this guide are calculated according to a standard spec. 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.

Frequently Asked Questions About House Building In England

Here are a few questions that provide extra insight into the cost of building a house in England.

How much does it cost to apply for Building Regulations in England?

The average cost for a full plan application for one dwelling is £860. To get an exact cost, you’ll need to find the information on your local authority’s website.

How much stamp duty will I pay when building a house in England?

If you’re looking to add some extra space and value to your property, a conservatory is often cheaper than building an extension. But how much does it cost to build a conservatory in the UK?

In this article, we’ve covered the costs of building three types of conservatories across multiple regions in the UK, and we’ve also provided a breakdown of the construction costs by stage as well as the costs per square metre.

Start your free trial with BuildPartner today to get the most accurate estimate of building a conservatory based on your own dimensions and specifications.

Conservatory Cost Considerations 

Our calculations are based on a 4 x 3m conservatory (12m2). The three main types of conservatory covered in this article include:

• Conservatory with a reinforced glass roof.
• Conservatory with slate roof tiles – including roof structure, insulation, plasterboard, decoration, light fittings, etc.
• Orangery with glass roof – including brick wall, cavity insulation, plasterboard, decoration, etc.

The costs do not include additional heating, such as radiators or underfloor heating.

Build Specifications and Supplier Benchmarks 

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

• 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.

For this particular cost breakdown, we have selected standard spec. In addition, 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.

Frequently Asked Questions About Conservatories

Here are a few questions about building conservatories in the UK.

What’s the difference between a conservatory and an orangery?

An orangery is fundamentally a brick structure with large glass windows and roofing, which provides more insulation than a fully glazed conservatory.

How can I make a conservatory more energy-efficient?

To make a conservatory more energy efficient, use triple glazing, install a tiled roof, and consider underfloor heating or energy-efficient radiators. Using blinds also regulates temperature.

Do I need planning permission for a conservatory?

Planning permission is generally not required for a conservatory if it meets permitted development rights. Your conservatory must be at the rear of the house, less than four metres high, less than 50% of the area of the land around the house, and its walls must run within the length of the property’s walls.

Renovating a flat in the UK requires careful cost planning and budgeting. In this 2024 guide, we provide a comprehensive cost breakdown of a 1-bedroom and 2-bedroom flat, and we also break the cost down per square metre.

Whether you’re undertaking a full-scale refurbishment or focusing on specific areas like the kitchen or bathroom, this guide furnishes you with the insights needed to navigate your renovation project.

Key Factors Affecting Flat Renovation Costs

When renovating a flat, several key factors come into play that significantly impact the overall cost. Firstly, the median floor space of the average UK flat is 58m2, so our calculations are based on a 2-bedroom flat of 64m2 and a 1-bedroom flat of 52m2, with both comprising an open-plan kitchen and living room and a bathroom. 

Our cost breakdown includes all appliances, such as a built-in dishwasher, fridge, freezer, washing machine, extractor fan, hob, and oven. The only exclusion is a central heating boiler; however, radiators are included.

It’s also important to distinguish between a renovation and a remodel. A renovation focuses exclusively on replacing the finishings and fittings in their existing locations and does not involve changing the layout of a structure.

Build Specifications & Supplier Benchmarks

In terms of build specifications, our BuildPartner pricing tool gives you three options when creating your quote (which can be revised by item at a later point):

• 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.

For each renovation type (1-bed and 2-bed flat), 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.

Frequently Asked Questions About Flat Renovations

Here are a few questions that shed some light on UK flat renovations.

How long does a flat renovation take?

Based on a 2-bedroom flat comprising an open-plan kitchen-living room and a bathroom, a renovation would take approximately four weeks.

This is based on two tradespeople carrying out the scheduled work (demolitions, heating and cooling, wall preparation, floor preparation, plumbed and wired appliances, kitchen units, decoration, and fixtures and fittings).

What is the most common pitfall when renovating a flat?

Since many flats are leasehold, they tend to have strict rules governing when noisy work can take place, often restricting it to specific hours on weekdays and prohibiting it altogether on weekends or evenings. It’s better to adhere to these to avoid potential conflicts and complaints.

Do I have to let my neighbour know before starting work?

If your renovation affects a shared or adjoining wall, you must notify your neighbour under the Party Wall Act 1996. A Party Wall Notice should be given at least two months before major work begins. Your neighbour then has 14 days to consent or request a Party Wall Agreement. Failing to notify them can lead to legal issues and project delays.

Do I need planning permission for a flat renovation?

Most internal renovations do not require planning permission, but you may need approval if you’re making structural changes, especially in listed buildings or conservation areas.

When calculating the cost of a loft conversion in the UK, several factors come into play that can significantly impact the final price. From the size of the space and the type of conversion—such as a Mansard or dormer extension—to additional features like en-suites or balconies, each element contributes to the overall building costs.

In this article, we’ll explore some of these variables and how they affect a project’s cost, to help you budget and plan your loft conversion.

10 Main Types of Loft Conversions

Before we take a look at the numbers, it’s important to be aware of the main options available when planning a loft conversion. Each type offers unique benefits and can significantly impact the overall cost and design of your project. Here are eight to be aware of:

1. Velux Loft Conversion – The simplest and most cost-effective option, involving the installation of Velux windows into the existing roof space without altering the roof structure.
2. Dormer Loft Conversion – Extending the roof outward to create additional space and headroom; they can be full-width or smaller, depending on the space requirements.
3. Mansard Loft Conversion – Altering the roof structure to create a near-vertical wall with a flat roof, providing maximum space and headroom.
4. Hip-to-Gable Loft Conversion – Replacing the sloping side of the roof with a vertical gable end, effectively increasing the roof space and headroom.
5. Gable-to-Gable Loft Conversion – Similar to hip-to-gable, but it extends the existing gable end across the entire width of the property. 
6. Shell Loft Conversion – Provides the basic structure and space, leaving the interior finishes and fittings to the homeowner.
7. Roof Lift Loft Conversion – Raising the entire roof structure to create additional headroom and floor space, often involving significant structural alterations.
8. Modular Loft Conversion – A prefabricated solution where sections of the loft are constructed off-site and then assembled on your property.
9. Piggyback Loft Conversion – Building an entirely new structure on top of the existing roof, effectively adding a new storey to the property
10. Standard Loft Conversion – Predominantly internal work without major changes like roof lifts or complete rebuilds.

In this article, we’ll be reviewing three loft conversion types: a standard loft conversion, a dormer loft conversion, and a Mansard loft conversion. A dormer loft conversion often comprises a single window, two windows, or the full width of the roof.

Considerations For Converting A Loft

A fully finished attic is roughly 35–50% of the house’s ground floor square meterage, so we based our calculations on a floor space of 30m2.

In addition to the total costs, we’ve also provided costs per square metre, so you can carry out your own calculations if you happen to know the dimensions you’re working with.

All our calculations are based on a loft conversion comprising the following:

• Master bedroom
• En-suite bathroom
• Eaves storage
• Landing including stairs

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

• 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 cost comparison article, we review projects based on a standard spec. In addition to 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.

Frequently Asked Questions About Loft Conversions

Here are some FAQs about loft conversions.

Do I need to move out during the loft conversion?

You rarely need to move out during most loft conversions. However, there will be noise, dust, and workers coming in and out, which can be particularly inconvenient if you work from home. For a roof lift loft conversion, which involves raising the existing roof to create additional headroom, many contractors recommend staying elsewhere until the property is weatherproofed.

How much headroom is required for a loft conversion?

Building Regulations require a minimum headroom of 2.2 metres (7 feet 2 inches) for a loft conversion, taken from the floor to the highest point of the ceiling. If your loft has less headroom, you may still be able to proceed by adjusting the roofline or lowering the ceiling of the floor below.

Can I convert a loft into a terraced or semi-detached house?

Yes, but you’ll need to consider specific factors, such as shared walls with neighbours (party walls), which may require a party wall agreement. Additionally, planning permission might be needed if your conversion alters the roofline or if your property is in a conservation area. 

What fire safety regulations apply for loft conversions?

In the UK, loft conversions must comply with strict fire regulations. This includes installing fire-resistant (30-minute rated) doors on all access points to the loft, creating a protected escape route with enclosed, fire-resistant walls and doors, and fitting mains-powered, interlinked smoke alarms on each floor. Emergency escape windows or alternative exits are also required.

June 30, 2024

The Department for Business has recently published the latest statistics on construction prices in the UK. In this article, we’ll explore the commentary and statistics, such as construction material price indices, bricks and blocks production, and imports and exports.

We’ll look at this and more, without the jargon, to help you understand the direction the construction industry is heading in and to help you interpret what that could mean for you.

Material Price Indices – Inflation

The material price indices tracks the changes in prices of various construction materials over time, providing a strong indicator of inflation (or deflation) within the construction industry. It comprises pricing data across numerous categories:

• Aggregates – e.g., gravel, sand, and bitumen.
• Cement and concrete – e.g., precast concrete, ready-mixed concrete, and fibre cement.
• Clay products – e.g., bricks, ceramic sanitaryware, and tiles.
• Metal products – e.g., central heating boilers, fabricated steel, and screws.
• Plastic products – e.g., pipes, windows, and floor coverings.
• Timber – e.g., plywood, planed wood, and particle board.
• Other building materials – e.g., plasterboard, paint, and insulation.

Here’s how building material prices have been affected by inflation over the last decade:

No surprises that the last few years have seen volatile inflation. The peak in 2021/22 occurred during the Covid-19 pandemic when there was a sharp rise in demand and supply shortages. 

Important! The above graph depicts inflation year on year, not actual price changes. For instance, post-pandemic, the inflation rate slowed, but prices actually continued to rise. 

Prices for “All Work” are now in a state of deflation, and have decreased a further 3.1% in April 2024 compared to April 2023, but now seem to have plateaued. Prices for “New Housing” decreased a negligible 0.2% year on year.

Biggest Movers In 12 Months (April 23 – April 24)

As far as actual construction material prices are concerned, here are the biggest movers in a 12-month period from April 23 to April 24:

Construction materials	% change
Pipes and fittings	19.3
Metal doors and windows	17.7
Gravel, sand, clays, and kaolin – excl. aggregate levy	11.3
Gravel, sand, clays, and kaolin – incl. aggregate levy	-12.8
Concrete reinforcing bars (steel)	-18.0
Fabricated structural steel	-22.7

Production of Bricks, Blocks, and Concrete

The production of bricks, blocks, and concrete is perhaps the most significant indicator of the demand for construction projects; these figures provide a tangible measure of construction activity in the industry.

Seasonally adjusted deliveries of bricks	Seasonally adjusted deliveries of concrete blocks
Seasonally adjusted sales of ready-mixed concrete	Seasonally adjusted sales of sand and gravel

In all four charts, the trend is broadly the same. Sales (in volume) and deliveries of these building components have reached their lowest point in almost two decades, with the exception of the sharp decline at the outset of the pandemic (in 2020) due to lockdown measures. The last two years are responsible for a further 20–30% decline in output.

What does a decrease in demand mean for prices? If we drill down into the data, we can see that prices for these commodities are actually moving upward:

Index	2019	2020	2021	2022	2023
Gravel, sand, clays and kaolin	116.1	119.3	126.4	152.4	157.4
Precast concrete: blocks, bricks, tiles and flagstones	114.3	115.8	119	145.2	161.4
Ready-mixed concrete	103.5	101.2	107.2	126.5	147.2
All bricks	[c]	[c]	[c]	[c]	[c]

[c] represents confidential data.

These commodities are less affected by a reduction in demand because they are necessities, that is, without them, most construction jobs cannot be completed.  

Imports and Exports

Where are building merchants and suppliers sourcing their products? There is an increasing trend towards importing building materials and components, especially since Brexit, while UK exports to other countries have been stagnant over the last decade.

• Most of the exports are to Ireland (£1.55bn), USA (£1.01bn), Germany (£0.75bn), the Netherlands (£0.65bn), and France (£0.55bn).
• Most of the imports are from China (£4.53bn), Germany (£2.13bn), Italy (£1.31bn), Spain (£1.25bn), and Turkey (£1.06bn).

Top 5 exports	£(million)	Top 5 imports	£(million)
Electrical wires	1,023	Electrical wires	2,756
Paints and varnishes	862	Lamps and fittings	1,090
Lamps and fittings	422	Sawn wood (> 6mm)	1,024
Air-con equipment	419	Air-con equipment	994
Linoleum flooring	360	Ironmongery	915

The annual trade deficit is widening because foreign suppliers can provide commodities much cheaper than UK suppliers. Almost as many building materials are now sourced from China as from Germany, Italy, and Spain combined.

What About Construction Output?

The Bank of England published its most recent update to the Agents’ Summary of Business Conditions in March. While no specific figures were reported, the report suggests that:

• Construction output volumes continue to fall
• House building has fallen markedly over the last year
• Commercial development continues to slow
• Housing associations continue to reduce new builds.

Some figures published by the Office for National Statistics (ONS) support this, suggesting that quarterly construction output saw a decrease of 0.9% in Quarter 1 (Jan to Mar) 2024 compared with Quarter 4 (Oct to Dec) 2023.

As for the overall housing market, the sentiment is slightly more positive among estate agents and economists:

• House prices appear to have bottomed out and are now expected to stay flat or grow modestly over the next few months.
• There are early signs of an improvement in demand, due to more supportive mortgage rates.

In terms of commercial real estate, development is broadly flat year on year and remains very weak, by historical standards. Developers cite the interest rate environment as the reason for this.

What About Construction Wages?

According to Statista, in March 2024, the average weekly wage of construction workers in the UK reached £739, which has been fairly flat for the last four years.

The chart below shows the average weekly earnings in the construction sector in the UK from June 2000 to March 2024.

This rise in wages is symptomatic of the shortage of labour in the construction industry, with vacancies reaching a peak of over 45,000 towards the end of 2023, the highest amount ever recorded.

Summary Of UK Construction Costs

Construction material prices are deflating, but this is likely a temporary adjustment following successive months, if not years, of price increases. In theory, prices dropping means it’s slightly easier for construction firms to lower their costs and pass on the savings to homeowners and developers. 

However, the reality is that the current rate of deflation is unlikely to stimulate any real demand in the short term. Only a period of sustained deflation would present an opportunity for a significant shift in consumer behaviour and an increase in output.

Frequently Asked Questions About UK Construction Costs

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

When calculating the costs for a home renovation, it’s easy to drown in a sea of variables such as what materials to include and exclude, what specifications to choose, and regional price variations. So, we’ve done the analysis for you. 

In this 2024 guide, we provide several comprehensive cost breakdowns. We compare three different types of specifications (basic, standard, and high), to accommodate a range of budgets, and we also break the cost down per square metre.

Renovating A 3-Bedroom House 

Before we look at the numbers, here are some things we’ve factored into the cost of renovating a 3-bedroom house:

1. The total floor area of the average house in the UK is 94m2. All our calculations are based on a house of this size comprising three bedrooms, one bathroom, one kitchen, one WC, one living room, a landing, and an entrance hall. 
2. All appliances are included in the price, such as a built-in dishwasher, fridge, freezer, washing machine, extractor fan, hob, and oven. The only exclusion is a central heating boiler (radiators are included).
3. A renovation (or house refurbishment) is not to be confused with a remodel. A renovation focuses exclusively on replacing the finishings and fittings in their existing locations and does not involve changing the layout of a structure.

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

• 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.
  

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.

Cost Of A Basic-Spec Renovation

Here’s a table showing the average building costs of renovating a 3-bed house for a basic-spec project in the UK:

All costs exclude VAT.

Here’s what the data shows for the cost of renovating a 3-bed house to a basic spec:

• It costs 26% more to renovate a 3-bed house in London than in other regions.
• The minimum cost is £38,357 and the maximum cost is £62,138.
• The total average cost is £45,986, or £494 per square metre.

Frequently Asked Questions About Home Renovations

Here are a few questions which will shed some light on UK home renovations.

How long does a home renovation take?

Based on a 3-bedroom property comprising the rooms listed above, a renovation would take approximately nine to 12 weeks when two tradespeople are carrying out the scheduled work (demolitions, heating and cooling, wall preparation, floor preparation, plumbed and wired appliances, kitchen units, decoration, and fixtures and fittings).

What’s the difference between remodelling and renovating a house?

The terms “remodelling” and “renovating” are often used interchangeably, but they refer to different projects. Renovating focuses on updating or restoring the house without altering its structure, such as installing new kitchens or bathrooms, replacing flooring or windows, and refreshing the home’s current condition.

Remodelling involves changing the structure of a house, such as altering the layout or adding new rooms, like creating open-plan spaces, adding bathrooms, and converting basements to transform the house’s function and appearance.

Do I need planning permission for my renovation?

Planning permission is not needed for internal renovations that don’t alter the structure or layout of a property. Exceptions include renovating a listed property or if you live within a conservation area, especially for alterations that affect the external appearance. Ultimately, it’s up to the local council to decide if the “character of the building” will be affected.
