House renovation cost in London
A whole-house figure tells you the scale of a renovation but not where the money goes. This guide sets out typical 2026 London ranges for cosmetic and full refurbishments, then prices the individual jobs inside them: rewiring, heating, kitchen, bathroom, windows and opening up walls. A worked budget shows how the pieces add up.

Quick answer
In 2026, cosmetic updates in London typically cost about £15,000–£30,000 and a full house refurbishment about £60,000–£120,000. Inside that, rewiring a three-bedroom London house costs about £8,100, an average new kitchen £10,000–£20,000 and a bathroom about £6,000. Keep 10–15% back for what opening up the house reveals, and check whether each figure includes 20% VAT.
London renovation costs by scope
Start by deciding which kind of renovation you are planning. These typical 2026 London ranges are rough estimates.
| Scope | Typical London range | What it usually means |
|---|---|---|
| Cosmetic update | £15,000–£30,000 | Painting, flooring and minor changes, with the layout and services left as they are |
| Kitchen and bathroom upgrade | £20,000–£40,000 | New kitchen and bathroom, with the plumbing and electrics they need |
| Full house refurbishment | £60,000–£120,000 | Most rooms renewed, often with a rewire, new heating, replastering and new kitchen and bathroom |
VAT may not be included in these ranges. Keep 10–15% for unexpected costs. For lofts and extensions, see our loft conversion cost and house extension cost guides.
Price the renovation job by job
A full refurbishment is a bundle of separate jobs. Pricing each one shows where a quotation is high, low or missing something.
| Job | Typical cost | Basis and scope |
|---|---|---|
| Full rewire, London house | 2-bed £5,600 · 3-bed £8,100 · 4-bed £10,500 | London, September 2026. Excludes replastering and redecoration; 5–7 days for a terrace or semi |
| Full rewire, London flat | 1-bed £4,000 · 2-bed £5,600 | London, as above; 3–4 days |
| Central heating where there is none | About £4,000 | Average three-bedroom home, UK |
| Replacement combi boiler | About £2,700 | UK average |
| New kitchen | £10,000–£20,000 on average | UK average |
| New bathroom | About £6,000 on average | UK average |
| Replacement uPVC window | £400–£600 each, installed | UK average |
| Knocking through an internal wall | Around £3,500 | UK average. Load-bearing walls need a structural design |
| Full structural survey before you buy | £500–£1,500 | UK average |
The UK-wide figures above rise in London and the South East, so treat them as a floor for a London budget.




Trade day rates behind the prices
Use day rates to sense-check the labour lines in a quotation, not to price the job yourself.
| Trade | Typical day rate |
|---|---|
| Electrician | Around £400 |
| Plumber | £325–£375 |
| Plasterer | Around £300 |
| Kitchen fitter | £250–£350 |
| Joiner | £240–£360 |
UK figures; London rates are usually higher.
A worked budget for a three-bedroom London terrace
A hypothetical full refurbishment, priced only from the typical figures above. It shows how the jobs add up, not a price for your house.
| Budget line | Lower figure | Higher figure |
|---|---|---|
| Full rewire, 3-bed London house | £8,100 | £8,100 |
| Central heating where there is none | £4,000 | £4,000 |
| New kitchen | £10,000 | £20,000 |
| New bathroom | £6,000 | £6,000 |
| 8 replacement windows at £400–£600 | £3,200 | £4,800 |
| Knocking through one internal wall | £3,500 | £3,500 |
| Subtotal of the priced jobs | £34,800 | £46,400 |
| Contingency at 10–15% | £3,480 | £6,960 |
| Total with contingency | £38,280 | £53,360 |
That total is well below the typical £60,000–£120,000 London range for a full refurbishment. The gap is the work with no single standard price: replastering, flooring, joinery, decoration, structural design, building control, protection, waste and, where figures exclude it, 20% VAT. Ask for those lines to be priced from your room-by-room schedule. Most of the job figures are UK averages, so a London quotation for the same items will usually be higher.
What pushes a London renovation price up
Older London houses often hide work that only shows once the house is opened up.
The age of the house
Victorian and Edwardian houses can have lath-and-plaster ceilings, old lead or galvanised pipework and wiring that was never designed for today’s loads. Replacing services usually means replastering the walls they run through.
What opening up reveals
Rot, damp and asbestos are the usual surprises. An asbestos survey before strip-out is required for refurbishment work in many buildings; read our refurbishment asbestos survey guide.
Changing the layout
Moving walls, the kitchen or the bathroom adds structural design, steelwork and new drainage routes. See structural alterations.
Living in during the work
Staying at home means phasing the rooms, keeping a working kitchen or bathroom and protecting the hallway and stairs. That adds time and protection costs, but can save on rent.
Access, parking and waste
Skip and parking-bay permits, restricted delivery times and carrying materials through the house all add to London prices. Read our construction waste guide.
Get the sequence right so nothing is done twice: services before plaster, plaster before joinery, joinery before decoration. Our renovation order of work guide sets out the stages.
Compare renovation quotations on the same basis
Renovation quotations differ most in what they leave out. Ask each builder to answer the same questions.
| Question | What to check |
|---|---|
| VAT | Is every figure shown with or without 20% VAT? |
| Room-by-room scope | Is each room priced separately, so you can see what changes if you drop or add one? |
| Strip-out and waste | Are removal, skips, permits and disposal included? |
| Unknowns | What provisional sums cover rot, damp or asbestos, and how is extra work priced? |
| Making good | After the rewire and plumbing, who replasters and redecorates the disturbed walls? |
| Supply | Who supplies the kitchen, bathroom fittings, tiles and flooring, and who fits them? |
| Living in | If you stay at home, which rooms stay usable and how long is each phase? |
| Payment stages | Are payments tied to completed stages? See our payment stages guide. |

House renovation cost questions
How much does a full house renovation cost in London?
A full house refurbishment in London typically costs about £60,000–£120,000. Lofts, extensions and structural changes come on top. The figure for your house depends on its size, condition and the specification you choose.
How much does it cost to rewire a house in London?
A London price guide updated in September 2026 gives about £5,600 for a two-bedroom house, £8,100 for three bedrooms and £10,500 for four, excluding replastering and redecoration.
How much contingency should I keep?
Allow around 10% of the total, or 10–15% for a London renovation. Older houses and larger strip-outs justify the higher end.
Do I need planning permission to renovate?
Most internal renovation does not need planning permission. Listed buildings need listed building consent, and a leaseholder may need the freeholder’s consent. Electrical, structural and heating work must meet Building Regulations.
Is it cheaper to stay in the house during the work?
It can save rent, but phasing, protection and a temporary kitchen or bathroom add time and cost. Ask for both options to be priced.
