The cost for full house renovation in the UK usually lands between about £30,000 and £110,000 for a typical three-bedroom home. That is roughly £650 to £2,800 per square metre, depending on size, condition and how deep the work goes. In this guide, we explain average prices, room-by-room costs, hidden extras and easy ways to save money. You will also find a full FAQ section at the end.
Renovating a whole house is exciting, but it can also be stressful. Walls come down, floors come up, and the bills can grow fast. That is why so many homeowners look up the average cost for full house renovation before they start saving or borrowing. The honest answer is that there is no single price. Your final number depends on your home and your plans.
The figures below come from UK cost guides and surveys published in 2025 and 2026. Different guides give different ranges, so treat every number as a starting point, not a quote. Always get written quotes from at least three builders.
What Is the Average Cost for Full House Renovation in the UK?
Several UK reports put the average price of renovating a three-bedroom house at about £76,690. Other guides give a wider range, from around £30,000 for a lighter job to well over £100,000 for a full strip-out.
Why is the gap so big? Because “full renovation” can mean very different things. One homeowner may only want new floors, fresh paint and a new bathroom. Another may want a new roof, new wiring, new heating and a new kitchen. The more you change, the higher the price goes.
A simple way to think about it is price per square metre. Most guides show a range from about £650 per square metre for basic updates up to £2,800 per square metre for a high-end job where everything inside the walls is replaced.
Cost for Full House Renovation by Size of Home
Here is an easy example. It uses £650 per square metre for a lighter renovation and £1,200 per square metre for a deeper one. This is only maths to help you plan. It is not a quote.
| Home size | Lighter job (£650/m²) | Deeper job (£1,200/m²) |
|---|---|---|
| 60 m² (small 2-bed) | £39,000 | £72,000 |
| 90 m² (typical 3-bed) | £58,500 | £108,000 |
| 120 m² (large 3 or 4-bed) | £78,000 | £144,000 |
Bigger homes can sometimes cost a little less per square metre. This is because fixed costs, like skips, scaffolding and project management, are spread over more rooms.
Three Levels of Renovation That Change the Price
1. Cosmetic refresh. This means painting, new flooring and small repairs. It is the cheapest level, often starting around £650 per square metre.
2. Medium renovation. This usually includes a new kitchen or bathroom, some rewiring or new pipework, and fresh plaster. Many guides place this around £650 to £1,100 per square metre.
3. Full strip-out. Here the house is taken back to the bare bones. Wiring, plumbing, heating, plaster, kitchen and bathrooms are all replaced. Guides often show about £1,100 to £1,800 per square metre, and luxury finishes can push it higher.
Before you ask for quotes, decide which level you really want. It is the biggest thing that moves your budget.
Room-by-Room Costs to Know
One 2026 UK guide lists these typical supply-and-fit ranges for a standard three-bedroom home:
- Full bathroom refit: £5,500 to £15,000
- Full rewire: £4,500 to £8,500
- Whole-house uPVC windows: £6,000 to £14,000
- Skips and waste removal for a full project: £1,000 to £3,000
Kitchen prices swing a lot, because cabinets, worktops and appliances range from budget to very expensive. Ask builders to split their quotes into clear lines so you can compare them fairly.
What Affects the Cost of Full Home Remodel?
The cost of full home remodel is not set by one thing. Many small choices add up. Here are the main factors:
- Size of the home: More square metres means more materials and more labour.
- Condition of the property: Old wiring, damp or a weak roof add extra work.
- Location: London and the South East usually cost more, because labour is dearer there. Materials cost about the same across the country.
- Quality of materials: Budget tiles and premium stone can differ by thousands of pounds.
- Structural work: Removing walls or adding steel beams needs engineers and approvals.
- Labour rates: Skilled trades often charge roughly £200 to £350 per day, depending on the trade and area.
- Hidden problems: Surprises behind walls are common in older homes.
In short, the cost of full home remodel goes up with every change to the structure of the house.
Hidden Costs Many Homeowners Forget
A builder’s quote often covers the main work, but real projects have extra bills. Remember to plan for:
- A building survey before you buy or start work
- Architect or designer fees
- Planning and building regulation fees
- VAT, which is usually 20% on building work if the builder is VAT-registered (ask if your quote includes it)
- Rent or storage if you cannot live in the house during the work
- Extra skips and waste removal
- Decorating, curtains and furniture at the end
How Much Extra Money Should You Keep for Surprises?
Experts often suggest keeping 15% to 20% on top of your cost for full house renovation, just in case. Old houses hide problems, and prices of materials can change while the job is running.
This advice matters. In one small survey of 300 UK homeowners in April 2026, about two in three said their project went over budget, and about six in ten said it ran late. Most people were still happy with the final result. The stress came from money and time, not from the quality of the work.
How Long Does a Full House Renovation Take?
For a typical three-bedroom home, a full renovation often takes about three to six months. Bigger jobs, structural changes, planning delays or slow deliveries can make it longer. Ask your builder for a written timeline, and agree what happens if the work runs late.
Tips to Lower the Cost for Full House Renovation
You cannot control every price, but you can control many choices. These tips help:
- Get three or more quotes. Compare the full scope, not only the total.
- Keep the layout. Moving kitchens, bathrooms and walls is expensive. Keeping them where they are saves money.
- Do the easy jobs yourself. Painting and clearing out rubbish can save labour costs.
- Choose mid-range materials. Spend more where it matters, like windows, and less on small decorations.
- Decide early. Changing your mind halfway costs time and money.
- Order big items early. Waiting for deliveries can delay everything.
- Pay in stages. Link payments to finished work, not to dates.
- Check your builder. Look at reviews, insurance and past work. There is no compulsory licence for builders in the UK, so checking is your job.
Final Thoughts on the Cost for Full House Renovation
A whole-house project is one of the biggest spends most people make. The smartest way to start is to decide how deep your renovation will go, work out the price per square metre, and then ask for detailed written quotes.
The cost for full house renovation can feel scary at first, but good planning removes most of the fear. Set a clear budget, keep 15% to 20% spare, avoid big changes mid-project, and choose a trusted builder. Do that, and you will be in a much better place to finish on time and enjoy your new home.
