House Renovation Cost UK – 2026 Price Guide
How much does a house renovation actually cost in the UK in 2026? This guide uses real pricing data from 519 UK towns to show realistic figures for cosmetic refreshes, medium renovations and full gut renovations — including the rewire, replumb, new kitchen and bathroom that drive the £99,000–£160,000 bill for gutting a typical 3-bed semi.
How much does a house renovation cost in the UK? Renovating a typical 3-bed semi costs £58,000–£99,000 in 2026 for a medium-depth renovation (£650–£1,100 per m²). A cosmetic refresh runs £18,000–£40,000, while a full gut renovation — rewire, replumb, new heating, kitchen and bathroom — costs £99,000–£160,000. London prices run 20–40% higher.
How Much Does a House Renovation Cost in the UK?
The honest answer is that "renovation" covers everything from a fortnight of decorating to a year-long structural rebuild. That is why quotes for the same house can differ by £100,000. The fastest way to budget realistically is to decide which of three depths of renovation you are actually doing — then price per square metre.
The bands below are drawn from BestBuilders platform data across 519 UK towns, cross-referenced against published 2026 guides from Checkatrade and the HomeOwners Alliance, and against our own UK Home Improvement Cost Index 2026. They include labour, materials, prelims and VAT at 20%, but exclude professional fees and any extension.
Full redecoration, new flooring, internal doors, light fittings and making-good. No layout changes, no new services. 4–8 weeks.

| Renovation depth | What's included | Cost per m² | 3-bed semi (~90m²) | Timeline |
|---|---|---|---|---|
| Cosmetic refresh | Decorating, flooring, doors, fittings, making-good | £200 – £450 | £18,000 – £40,000 | 4–8 weeks |
| Medium renovation | + new kitchen, new bathroom, partial rewire, replastering | £650 – £1,100 | £58,000 – £99,000 | 3–5 months |
| Full gut renovation | + full rewire, replumb, new heating, replaster throughout, new windows | £1,100 – £1,800 | £99,000 – £160,000 | 6–12 months |
| London & South East | Same scope, higher labour and access costs | +20 – 40% | e.g. gut £120,000 – £225,000 | — |
Per-m² figures are for habitable floor area, all trades and VAT included. Structural alterations, extensions, loft conversions and professional fees (architect, structural engineer, building control — typically 5–12% of build cost) are extra.
How Much Does It Cost to Renovate a House by Size?
Floor area is the single biggest cost driver after depth of works, because plastering, rewiring, flooring, decorating and heating all scale with the square metres you own. Here is what the three renovation depths look like across common UK house types in 2026.
| House type | Typical area | Cosmetic refresh | Medium renovation | Full gut renovation |
|---|---|---|---|---|
| 2-bed terrace | ~70m² | £14,000 – £31,000 | £45,000 – £77,000 | £77,000 – £126,000 |
| 3-bed semi | ~90m² | £18,000 – £40,000 | £58,000 – £99,000 | £99,000 – £160,000 |
| 4-bed semi / small detached | ~110m² | £22,000 – £50,000 | £71,000 – £121,000 | £121,000 – £198,000 |
| 4–5 bed detached | ~125m² | £25,000 – £56,000 | £81,000 – £137,000 | £137,000 – £225,000 |
| Large detached | ~160m² | £32,000 – £72,000 | £104,000 – £176,000 | £176,000 – £288,000 |
Two things push a project towards the top of each band: condition (a house untouched since the 1970s needs everything; a 2000s house may keep its wiring and windows) and specification (a bespoke kitchen alone can swallow £30,000+).
If your plans also include adding space, price that separately — see our guides to house extension costs and loft conversion costs. Renovating existing rooms is almost always cheaper per square metre than building new ones.
What Does Each Part of a Renovation Cost?
Whole-house bands are useful for sanity-checking a budget, but builders price job by job. These are typical 2026 trade prices for each element on a 3-bed semi, drawn from the same 519-town dataset behind our individual cost guides.
| Job | Typical cost (3-bed semi) | Notes |
|---|---|---|
| Full rewire | £3,800 – £6,500 | 8–10 circuits, new consumer unit, Part P certified |
| Full replumb | £3,500 – £8,000 | All hot, cold and waste pipework renewed |
| New boiler & central heating | £4,000 – £8,000 | Boiler, radiators, controls; heat pumps cost more before grants |
| Replastering throughout | £4,000 – £7,000 | Skim and re-plaster, whole house |
| New kitchen (mid-range) | £8,000 – £20,000 | Rigid units, quartz or solid worktops, fitted |
| New bathroom | £4,500 – £10,000 | Standard suite, tiling, full refit |
| Double glazing (8–10 uPVC windows) | £4,000 – £6,000 | FENSA/CERTASS installer; aluminium or timber cost more |
| Flooring throughout | £2,500 – £7,500 | Carpet/laminate lower end, engineered wood upper |
| Decorating throughout | £3,000 – £6,500 | Prep, paint, woodwork, whole house |
| Damp treatment (if needed) | £1,500 – £4,000 | Whole-house chemical DPC with re-plastering |
| Structural knock-through + steel | £2,500 – £7,500 | Per opening, incl. engineer's calcs and building control |
| Skips & strip-out waste | £1,500 – £3,000 | A full gut typically fills 4–8 skips |
Add every line up and a full gut renovation comes to roughly £43,000–£94,000 in pure trade costs. The gap between that and the £99,000–£160,000 whole-house band is everything renovators forget: scaffolding, prelims and site set-up, waste beyond the first skips, professional fees, building control, a proper 10–15% contingency — and VAT.
If the survey flags roof problems, deal with them first — a re-roof is £6,500–£14,500 on a 3-bed semi (see our roofing cost guide) and there is no point hanging new plaster under a leaking roof.

In What Order Should You Renovate a House?
Sequencing is where self-managed renovations lose money. Fit a kitchen before the rewire and you will pay to rip chunks of it out again. The rule: watertight first, first fix before finishes, floors last.
Where Do House Renovation Costs Blow Up?
Most renovations don't fail on the headline quote — they fail on what nobody priced. These are the six blow-ups we see most often in 2026 project data, and what they typically add.
Common in pre-2000 homes: textured coatings, floor tiles, soffits, flues. A survey costs £200–£400; licensed removal typically £1,000–£3,500+. Never disturb it to save money.
Dry rot behind old plaster or under floors can add £1,000–£5,000. Get a proper survey before you exchange, not after the strip-out.
Cracked lintels, undersized joists, DIY knock-throughs by previous owners. Engineer's fees plus remedial steel can add £3,000–£10,000 on older stock.
Listed building consent, matching materials and specialist trades typically add 30–50% versus a standard renovation, and months to the programme.
Changing your mind after first fix is the most expensive habit in renovation. Every moved socket or relocated radiator is paid for twice.
Hold 10–15% of the build cost in reserve — untouched until something genuinely unforeseen appears. On a £100,000 gut renovation that's £10,000–£15,000.
Can You Save VAT on a House Renovation?
VAT is the forgotten fifth of a renovation budget. Renovation work on an occupied home is standard-rated at 20% — but there are two legitimate ways the bill comes down.
The empty-home 5% rate. If the property has not been lived in for the two years immediately before work starts, a VAT-registered builder can charge the reduced 5% rate on qualifying renovation work under VAT Notice 708. On a £120,000 gut renovation that is a saving of around £15,000. Council tax records or the local authority's empty property officer can evidence the empty period — sort this before work starts, because you cannot reclaim overcharged VAT from HMRC afterwards. Conversions that change the number of dwellings can also qualify for 5%.
Non-VAT-registered builders. Sole traders below the £90,000 VAT registration threshold don't charge VAT on their labour. That is perfectly legal and common on smaller cosmetic jobs — but be wary of anyone offering to "lose the VAT" for cash. No paper trail means no warranty, no recourse and problems when you sell.
Other savings that don't hurt quality: do your own demolition and decorating, keep the existing layout (moving soil stacks and structural walls is where money vanishes), buy sanitaryware and flooring in sales yourself, and get three itemised quotes for every package of work rather than one round number.
Common Questions About House Renovation Costs
A medium renovation of a 3-bed semi — new kitchen, new bathroom, partial rewiring, replastering and full redecoration — costs £58,000–£99,000 in 2026. A cosmetic refresh costs £18,000–£40,000, while a full gut renovation including a rewire, replumb and new heating system runs £99,000–£160,000.
A full gut renovation strips the house back to brick and rebuilds every system: full rewire, complete replumb, new boiler and central heating, replastering throughout, new kitchen, new bathroom, new flooring, full redecoration and usually new windows. Structural alterations such as knock-throughs, damp treatment and roof repairs are often added on top.
In 2026, budget £200–£450 per m² for a cosmetic refresh, £650–£1,100 per m² for a medium renovation, and £1,100–£1,800 per m² for a full gut renovation. London and the South East typically run 20–40% above these figures, while Northern England, Scotland and Wales often come in below them.
Work from the outside in and from first fix to finishes: 1) make the building watertight (roof, gutters, windows, damp), 2) strip-out and structural work, 3) first-fix electrics, plumbing and heating, 4) plastering, 5) second-fix electrics and plumbing, 6) kitchen and bathroom fitting, 7) decoration, 8) flooring last. Paying for finishes before first-fix work is complete is the most expensive mistake renovators make.
You can live through a cosmetic or room-by-room renovation, but a full gut renovation usually means moving out for 3–6 months. With no working kitchen, bathroom, heating or safe electrics, staying put slows the trades down and typically adds 10–20% to labour costs. Factor rent or temporary accommodation into your budget.
Most internal renovation work does not need planning permission — it falls under Permitted Development. You will need consent for extensions beyond PD limits, most work on listed buildings, and some changes in conservation areas. Building Regulations approval is separate and always applies to structural work, rewiring, new heating and replacement windows.
For a typical 3-bed house in 2026: a cosmetic refresh takes 4–8 weeks, a medium renovation 3–5 months, and a full gut renovation 6–12 months including design and ordering time. Add 4–12 weeks up front if you need planning permission, and longer for listed building consent.
Yes, in specific cases. If the property has been empty for two years or more immediately before work starts, a VAT-registered builder can charge the reduced 5% rate on qualifying renovation work under VAT Notice 708. Conversions that change the number of dwellings can also qualify. Ask your builder to apply it — you cannot reclaim it retrospectively from HMRC yourself.
Almost always, per square metre. Renovation reuses the existing structure, so even a full gut at £1,100–£1,800 per m² undercuts extension building costs, and a medium renovation at £650–£1,100 per m² costs roughly a third of new-build space. Renovate the space you have before you pay to build more — then compare extension quotes if you still need the room.
