House Renovation Costs UK 2026: Room-by-Room Breakdown
2026-05-13
Every property investor knows that renovation is where value is created. Buy a tired house, refurbish it properly, and the uplift in value or rental income can dwarf the cost of the work. But "properly" is doing heavy lifting in that sentence. The difference between a profitable renovation and a financial disaster almost always comes down to one thing: how accurately you estimated the costs before you started.
This guide gives you the 2026 numbers. Room by room, trade by trade, with the contingencies and hidden costs that every budget spreadsheet forgets.
The Reality of UK Renovation Costs in 2026
Material prices stabilised through 2025 after the volatility of 2022-2024, but they haven't come down. They've settled at the new, higher level. Timber is 30-40% above pre-pandemic prices. Copper, steel, and cement have all plateaued above their 2021 levels. Labour costs have risen too, driven by skilled trade shortages that show no sign of easing.
The result: renovating a house in 2026 costs roughly 25-35% more than the same work would have cost in 2019. Anyone using pre-pandemic cost guides is underestimating by a significant margin.
:::stats 25-35% | Cost Increase vs 2019 £1,200-£1,800/m² | Light Renovation £1,800-£2,500/m² | Full Renovation £2,500-£3,500/m² | High-Spec / Structural :::
Kitchen Renovation
The kitchen is typically the highest single-room cost in a renovation and the room most likely to add genuine value. Get the balance right between spend and specification.
Budget Kitchen (Rental Standard)
Suitable for buy-to-let or HMO. Functional, durable, no frills.
| Item | Cost Range |
|---|---|
| Units + worktop (flat-pack, laminate) | £1,500-£3,000 |
| Installation | £1,000-£1,500 |
| Plumbing (sink, washing machine, dishwasher) | £400-£800 |
| Electrics (sockets, cooker point, extractor) | £300-£600 |
| Tiling (splashback only) | £200-£400 |
| Flooring (vinyl plank) | £300-£600 |
| Decoration | £200-£400 |
| Total | £3,900-£7,300 |
Mid-Range Kitchen
For flips or higher-end rentals. Solid timber carcasses, stone-effect worktop, integrated appliances.
| Item | Cost Range |
|---|---|
| Units + worktop (mid-range, quartz or solid surface) | £4,000-£8,000 |
| Installation | £1,500-£2,500 |
| Plumbing | £500-£1,000 |
| Electrics | £500-£800 |
| Tiling (full walls or splashback) | £400-£800 |
| Flooring (LVT or porcelain) | £500-£1,000 |
| Decoration | £300-£500 |
| Total | £7,700-£14,600 |
[!tip] The investor rule on kitchens For BTL: spend the minimum that looks clean, modern, and durable. Tenants need a functional kitchen, not a showroom. For flips: spend enough to match the neighbourhood expectation. Over-speccing a kitchen in a £180,000 terrace doesn't get you £180,000 terrace + kitchen cost back.

| Total | £3,350-£6,700 |

Bedroom Renovation
Bedrooms are usually the cheapest rooms to renovate, which is why they offer good ROI when done right.

|---|---|---|
| Decoration (walls + ceiling) | £300-£600 | Per room, professional |
| Flooring (carpet) | £200-£500 | Per room, fitted |
| Flooring (LVT/laminate) | £300-£700 | Per room, fitted |
| New door + handles | £100-£250 | Fire door for HMO: £200-£350 |
| New radiator | £200-£400 | Including fitting |

| Total (light refresh) | £500-£1,100 | |
| Total (full refurb) | £1,200-£2,500 |
Living Room / Reception
| Item | Cost Range |

| Feature wall / fireplace removal | £300-£800 |
| Coving / skirting replacement | £200-£400 |
| Total | £1,000-£2,500 |
Structural and Major Works
This is where budgets get serious. Structural work is the single biggest source of cost overruns in renovation projects.
| Work | Cost Range | Notes |
|---|---|---|
| Full rewire (3-bed) | £3,500-£5,500 | Add £500-£1,000 for consumer unit upgrade |
| Full replumb (3-bed) | £3,000-£5,000 | Hot/cold, radiators, bathroom feeds |
| New central heating system | £3,000-£6,000 | Boiler + radiators + controls |
| Boiler replacement only | £2,000-£3,500 | Combi, installed |
| Damp proofing | £1,500-£5,000 | Depends on extent and method |
| Roof repair (patch) | £500-£2,000 | Slate/tile replacement, flashing |
| Roof replacement (full) | £5,000-£12,000 | Dependent on size and access |
| Structural wall removal | £1,500-£3,500 | Including RSJ, building regs |
| Underpinning | £10,000-£25,000+ | Worst case — avoid unless essential |
| New windows (full house) | £3,000-£8,000 | UPVC, 6-8 windows |
| Loft conversion (dormer) | £35,000-£55,000 | Including stairs, bathroom, building regs |
| Single-storey extension | £30,000-£60,000 | Dependent on size and spec |
[!warning] Structural surveys save thousands A Level 3 (full structural) survey costs £500-£1,000. It regularly uncovers problems that would cost £10,000+ to fix. Never skip the survey on a property you plan to renovate. The money you "save" by going with a basic valuation is a gamble with terrible odds.
The Costs Everyone Forgets
These are the line items that silently blow renovation budgets:
Skip hire: £250-£400 per skip. A full house renovation can easily need 3-4 skips. Budget £1,000-£1,500.
Scaffolding: £600-£1,200 per week for a standard 3-bed terrace. If your roofer, window fitter, and renderer all need scaffolding at different times, coordinate or you'll pay for it three times.
Building regulations: Structural work, electrical rewiring, plumbing changes, and window replacements all need building control sign-off. Fees are typically £300-£600 per application.
Party wall agreements: If your renovation affects a shared wall (terraced or semi-detached), you may need a party wall agreement. Surveyor costs: £700-£1,500 per neighbour.
Asbestos: Present in many pre-1990 properties. Testing: £50-£100 per sample. Removal: £500-£3,000+ depending on type and location. Legally, you cannot just rip it out yourself.
Utilities disconnection/reconnection: Moving a gas meter or upgrading the electrical supply can cost £500-£2,000 and take weeks to arrange.
Council tax on empty property: Many councils charge full council tax (some charge 200-300% premium) on empty properties. If your renovation takes 6 months, that's a real cost.
Cost Per Square Metre Benchmarks
For quick estimates, cost per square metre is a useful sanity check:
| Renovation Level | Cost/m² | What It Covers |
|---|---|---|
| Cosmetic refresh | £500-£800 | Decoration, flooring, basic kitchen/bathroom refresh |
| Light renovation | £1,200-£1,800 | New kitchen, new bathroom, full redecoration, some electrics |
| Full renovation | £1,800-£2,500 | Rewire, replumb, new heating, kitchen, bathroom, all finishes |
| Structural + high spec | £2,500-£3,500 | Everything above plus structural changes, extensions, high-end finishes |
A 90m² Victorian terrace at "full renovation" level: 90 x £2,000 = £180,000 baseline estimate. Add 15% contingency = £207,000.
Regional Price Variation
Labour costs vary significantly across the UK:
| Region | Labour Index | Notes |
|---|---|---|
| London | 130-150% | Highest labour, highest material delivery costs |
| South East | 110-125% | Premium, especially near London |
| South West | 100-115% | Bristol higher, rural areas lower |
| Midlands | 90-100% | Baseline pricing |
| North West | 85-95% | Good value, strong trade availability |
| North East | 80-90% | Lowest labour costs in England |
| Scotland | 85-100% | Edinburgh/Glasgow higher, Highlands add travel costs |
| Wales | 80-95% | Generally lower, but limited trade availability in rural areas |
These are rough indices. A kitchen that costs £5,000 to install in Sunderland might cost £7,500 in Surrey.
Building Your Renovation Budget
The professionals don't guess. They write a detailed specification — room by room, item by item — before they price a single trade. This is the only reliable way to get accurate quotes and control costs during the project.
The Renovation Spec tool lets you build a professional-grade specification with UK pricing baked in. Room by room, you select the work, adjust quantities, and get a total with line-item detail. It's the same approach used by quantity surveyors, adapted for property investors.

The 70% Rule for Flippers
If you're renovating to flip, a common rule of thumb is the 70% rule:
Maximum Purchase Price = (After Repair Value x 70%) - Renovation Cost
On a property worth £250,000 after renovation, with £40,000 of work needed: (£250,000 x 0.70) - £40,000 = £135,000 maximum purchase price
This leaves room for SDLT, finance costs, selling costs, and profit. If you can't buy at or below this number, the deal doesn't work. For a full flip cost breakdown, see Property Flip Calculator.
Run the full acquisition and renovation numbers through the Deal Analyser to stress-test whether the deal still works if costs overrun by 15-20%.
