How Much Does It Cost To Renovate a House in 2026?
Last updated February 2026
In 2026, the average cost to renovate a house in the UK typically ranges between:
£1,200–£2,800 per square metre (or roughly £110–£260 per square foot).
So for a typical 100m² three bedroom house, that equates to around £120,000–£280,000.
The final figure will depend heavily on:
Location (London and the South East can be 20–40% higher)
Specification level (budget vs mid-range vs premium finishes)
The extent of structural work required
Whether layout changes, loft conversions or extensions are involved
But headline averages only tell part of the story.
Based on 50 real UK renovation budgets submitted by our community in 2025/26, most full house renovations clustered between £60,000 and £200,000, with extension-led projects frequently exceeding £250,000–£300,000.

How to budget for your house renovation costs in 2026
We’ve worked with over 1,500 UK renovators who all started exactly where you are right now. Trying to answer the same question: “How much does it cost to renovate a house in the UK?”
And not to spook you, but according to the Hiscox Report:
2 in 5 renovators overshoot their budget by an average of 20%
The difference usually comes down to how detailed you are with your budgeting.
Renovators who underestimate house renovation costs in the beginning can start running out of cash rapidly when the project is underway. But those who properly itemise their budget before starting have a far higher success rate.
Neil and I learned this ourselves, the hard, expensive way 🙄
Back in 2016, Neil and I spent £95,000 renovating our 1930s semi. Adjusted for 2026 pricing, that same project would likely cost £130,000–£150,000 today. And because we were so new to renovating, we made some costly errors throughout.
If you’re interested in learning from our failures I recommend downloading the full breakdown from our 2025/26 UK renovation cost survey which includes cost-saving tips we recommend, plus those real projects you can bench-mark yours against. This insight will reduce the chances of your costs spiralling.
Below, I’ll break down:

House Renovation Costs for a 3 Bedroom House in the UK (2026)
For most UK homeowners renovating a typical three-bedroom house (around 90m²–120m²), total renovation costs in 2026 usually range between £120,000 and £280,000 depending on location, specification and structural work.
We know this first hand. Back in 2016, we renovated our own 1930s house renovation which was a 3 bed… a project that ultimately shaped our entire career.
We’re neil & Fi!
The property hadn’t been updated since the 1960s and needed everything doing. We were new to renovating, had no industry contacts, and no real idea what labour costs would look like. Like most homeowners, we turned to Google and built our own itemised house renovation costs spreadsheet to estimate each stage of work, including contingency.
Those early “safe bet” calculations gave us confidence we could afford the project and taught us how critical detailed budgeting is - before you even pick up the keys.
Six years later, I trained as an interior designer and now support renovators through everything from knock-throughs to double-storey extensions. The lesson remains the same:
Gather informed, realistic estimates before you commit.
It’s the single best way to protect your budget and avoid expensive mistakes.
And by the way, if you love before and after renovation shots, you might like a nosey of ours.
We know how you feel right now, because we’ve been in your shoes.
The worry about overspending can be exhausting. But it’s become my aim to reveal the industry secrets we wish we had access to back then, to help you save money.
Cost to renovate a 3 bed semi-detached house in the UK
Based on both our own 1930s semi renovation and budgets submitted by our 2025/26 community survey, a standard 3-bedroom semi-detached house in the UK typically costs:
£75,000–£150,000 for a full internal renovation (excluding extensions or loft conversions).
This range assumes:
Rewiring
New central heating and plumbing
New kitchen and bathroom
Plastering and decorating
Flooring throughout
Costs increase significantly where:
Structural layout changes are involved
Extensions or loft conversions are added
High-end finishes are specified
The property is located in London or the South East
Every property differs, but this gives you a realistic benchmark before you start gathering contractor quotes or if you’re looking for a house to renovate.

Average House Renovation Costs From Our 2025/26 Survey
In November 2025 we asked 50 of our home renovation course students via a questionnaire what their budget was, and crunching the numbers, out of the responses received, the average budget was £159,000. Many of these students were very certain about their figures as they’d either received estimates or partially completed their projects.
Here is a round-up of the data. As you can see, there is quite a wide range, but it should help you get an idea of the average cost to renovate a house – or at least a ballpark amount to start with. Our free costs download will show you details about their project scope (plus tips on how to save money).
| Budget (From) | Budget (To) | Renovations |
|---|---|---|
| £0 | £49,999 | 1 |
| £50,000 | £99,999 | 14 |
| £100,000 | £149,999 | 14 |
| £150,000 | £199,999 | 1 |
| £200,000 | £249,999 | 1 |
| £250,000+ | 8 |

Important things to know when working out your budget:
There is a huge North-South divide when it comes to renovation costs
You might as well ignore labour cost estimates from outside your part of the country. (We wouldn’t be surprised if we start seeing people hiring from cheaper areas!)Websites can show out-of-date cost information
Throughout the pandemic the costs of supplies rose enormously and continue to be volatile - especially with inflation in place. It’s why we take our info from real-life client & student projects.Always set a contingency budget (more about this in our free guide below).
What were our house renovation costs?
Our renovation was slightly unusual because the property had no gas and no central heating when we moved in, which immediately increased the scope of work.
Initially, we planned a rear extension, but after reviewing the projected costs (an additional £100,000+), we decided to remodel the internal layout instead.
The first phase of our renovation, which included knocking down a wall between the existing kitchen and dining room to make it open-plan, and making the house comfortable to live in, cost approximately £65,000.
As the project progressed, we addressed structural and remedial issues flagged in our survey, including:
Window replacement
Asbestos removal
Drainage repairs
Wall tie replacement
Roof updates
Once everything was complete, our total renovation costs reached £94,000.
Adjusted for 2026 pricing, that same project would likely cost £130,000–£150,000 today. Not every property will require this level of structural work, but these kinds of hidden issues are common in older UK homes and should always be factored into your contingency budget.

Real House Renovation Costs From Our Community (UK - 2026)
We’ve been running our renovation community for many years now, and it’s interesting to hear what kinds of budgets our renovating students are looking at. Here’s a closer look at some of the types of renovations we support people through:
Property type: 3 Bed Victorian house renovation
Location: South-East London
Approximate budget: £150,000
Project details: “We’re planning to completely redecorate, extend the kitchen into the side return, replace the bathroom, and potentially change the ground floor layout to use the space better. We may also consider extending into the loft.”
Property type: 2 bedroom bungalow
Location: Northumberland
Approximate budget: £130,000
Project details: “Our initial thought is to completely change the layout. Move the kitchen and lounge to the back of the house and extend to make a bigger kitchen/dining area and move the bedrooms to the front, whilst creating an additional room, which would be my craft room/additional sleeping space with sofa bed. In addition, the thought is knock down the detached single garage and build a bigger garage into the side of the house with more storage space.”
Property type: 2 Bedroom Victorian terraced house
Location: Brighton
Approximate budget: £100,000
Project details: “We are going to knock out a wall between the hall and dining room to create a more open plan space and install French doors from dining room out into the back yard. Putting a walk-on-able flat roof on the outhouse to utilise the raised garden space and make the outhouse into a habitable room. Either knocking through to make the kitchen into a kitchen breakfast room or keeping it separate for storage/a garden room. Creating a mansard loft extension to add (hopefully) 2 additional bedrooms and a shower room”
Property type: 3 Bed semi-detached
Location: Glasgow
Approximate budget: £85,000
Project details: “Rewire, full new central heating system and plumbing, old one removed including asbestos water tank, all walls skimmed and painted etc, replacement coving, doors, new flooring in parts, new bathroom, kitchen and plans for an extension after kitchen is knocked into dining room, roofing, rendering, soffits, new front door. Not to mention plans for front and back garden, replacement of garage, and a garden room for my work studio!”
House refurbishment costs and what to watch out for!
In our online course for first-time renovators, we give students an extensive list of curveball renovation costs to watch out for, plus industry-known practices to make savings on their projects.
Some of the areas we help with are:
Quotes coming back higher than expected – This is so common. We help students pull back their spending in ways that are least compromising to their goals for their homes.
Incorrect cost comparison – Quotes are never usually like for like, so this is a big one to be careful with. You’ve got to be asking contractors the right questions.
Costs spiralling – This is an easy trap to fall into, which can lead to an incomplete or lacklustre project. Renovators can give themselves a head start by understanding the order of events (to prevent rework) and by avoiding common mistakes. We outline these in our online course and we provide a lot of free support to renovators joining our mailing list.
How much does an extension cost in the UK? (2026)
In 2026, the cost of building a house extension in the UK typically starts from £2,500 per square metre, with most projects ranging between £40,000 and £120,000+, depending on size, location and specification.
A single-storey rear extension of 20m²–30m² will often fall between £60,000–£90,000 in much of the UK, with higher figures common in London and the South East.
Costs increase significantly where projects include:
Structural steel and knock-throughs
Large areas of glazing or rooflights
High-end kitchens within the extension
Bespoke cladding or complex design features
For example, our students Jen & Stu (South East, 2023) spent £70,000 on their rear extension, completed to a high standard.
As always, use a per square metre estimate for early planning, but gather location-specific contractor quotes before committing.
Building a house extension to your existing home is a fantastic way to shape your house to your needs. In fact, rear extensions and side extensions have only increased in popularity in the last few years with many of our community completing extensions to a high standard.
Before
After!
Actually, Neil and I wrote about our experience with kitchen extension costs (and why we had to ditch the idea 😅). But many factors will come into play when you are considering what type of extension you may wish to build. Design is one thing, but the cost of an extension may determine what you are able to afford with your property and your budget.
How much does a loft conversion cost in the UK?
In 2026, a loft conversion in the UK typically costs between £40,000 and £70,000, with the national average sitting around £45,000–£55,000.
Costs depend heavily on:
Whether structural reinforcement is required
The type of conversion (Velux, dormer, mansard)
Whether a new staircase is needed
Adding an en suite bathroom
The quality of finishes
Our students Jen & Stu spent £50,000 on their loft conversion with en suite in the South East (2022 pricing).
Loft conversions can be more cost-effective per square metre than extensions, but complexity and head height constraints will influence feasibility and price.
Jen + Stu’s Hip to gable loft conversion
The main items to consider when considering a loft conversion is the size of the loft space, namely that there is enough head height so that someone can occupy the conversion without hitting their head! The second thing is to note the position of the stairs in the house. Will it be easy to provide access to the loft without changing too much of the floor below? And how many windows will be added? Will you add an en suite? And how ‘luxury’ will you finish it (lighting, flooring, etc)? These decisions will all inform the costs of your loft conversion.
How much does a new bathroom renovation cost?
A new bathroom renovation in the UK typically costs between £6,000 and £15,000, although basic refurbishments can start from around £3,000 and high-end designs can exceed £20,000+.
Costs vary based on:
Whether plumbing locations are moved
The quality of sanitaryware and fittings
Tiling coverage
Labour rates in your area
Specialist installations such as wet rooms
Keeping the plumbing layout the same is one of the most effective ways to control costs.
One of our Reno Club students reduced their bathroom renovation budget significantly simply by retaining the existing pipework configuration.

AFTER (almost!)
How much does a kitchen renovation cost in the UK?
In 2026, a kitchen renovation in the UK typically ranges between £8,000 and £30,000, with bespoke or high-end kitchens reaching £50,000+.
Budget kitchens with minimal layout changes may fall at the lower end of the range, while costs increase where projects involve:
Structural alterations
New electrics and plumbing
Bespoke cabinetry
Stone worktops
Premium appliances
Our students Matt & Georgie completed their bespoke kitchen for approximately £17,000 by carefully managing specification and supplier choices.
The biggest cost drivers in a kitchen renovation are cabinetry, worktops and labour. Reducing layout changes can dramatically lower the overall price. What a beautiful result👇🏻
our student’s kitchen came in at £17K (matt & georgie)
Factors that will lower your kitchen price include:
Sourcing cheaper materials
DIY when fitting the kitchen
Having a smaller kitchen (fewer cabinet costs, lower sqm worktops etc.)
Little to no changes to the plumbing and electrics or appliances
Matt + Georgie moved their kitchen into the dining room
Factors that may increase your kitchen price include:
Having a bespoke kitchen made and fitted
Expensive materials and fittings (Such as marble worktops and stone floors)
A larger kitchen, including islands and new appliances
Works that may be required to house the kitchen (plumbing, electrics etc.)
Is 40K enough to renovate a house?
£40K is a very tight budget and would probably only cover the basics but it can be done! Our course student Anna wrote about she renovated a small cottage in Cornwall with £40K and wrote “Renovating on a budget” – so make sure to check that out if you’re working with very tight budgets.
3 quick tips to reduce your home renovation costs
1. Design for your lifestyle, not excess
Instead of adding costly extensions or knocking down major walls (which will add up fast ££!), explore how you can work with your existing layout. How can your current layout be adjusted to suit your lifestyle without structural work? One example could be introducing sliding or pocket doors to create openness without altering structural elements. Focus on flow and function. Because I promise you, a well-thoughtout layout can feel just as spacious as adding extra square footage – without the hefty price tag!
2. Time your renovation strategically
Plan your renovation around sales cycles and seasonal discounts. So for tradespeople, avoid peak demand periods – booking them during quieter months, like late autumn or winter, which can result in lower quotes.Kitchen and bathroom suppliers also run significant sales during November and after Christmas which will help you make a tidy saving.
3. Salvage and upcycle wherever possible
Renovators often overlook the cost-saving potential of reclamation yards, auctions, or even online marketplaces like Facebook Marketplace and eBay. If you’re willing and able, you can find high-quality materials, period features, and furniture for a fraction of the cost of buying new that needs a clean up and a lick of paint. For example, reclaimed wood can make stunning flooring or feature walls, while vintage doors or fixtures add character and save money.
Just a few tips here, but look at our renovation course for ways to prevent your costs spiralling and spread your budget effectively.
