Average Cost of a Kitchen Renovation Per m² 2026 (UK)
A kitchen renovation costs £1,000–£1,500 per m² at budget spec, £1,500–£2,500 per m² mid-range and £2,500–£4,000 per m² at high end in 2026 — before any structural work. So an average 12m² kitchen lands around £16,000–£28,000, and a small 8m² galley from about £10,000. The per-m² lens is the quickest way to sanity-check a quote and see where your money is going. Here is what each tier actually buys, when spending more adds value, and how rates shift across the UK.
Kitchen renovation cost per m² (2026)
| Spec tier | Cost per m² (2026) | 12m² kitchen ≈ |
|---|---|---|
| Budget refit | £1,000–£1,500 per m² | £12,000–£18,000 |
| Mid-range renovation | £1,500–£2,500 per m² | £18,000–£30,000 |
| High-end renovation | £2,500–£4,000 per m² | £30,000–£48,000 |
| Structural / layout change | +£2,000–£8,000 | Moving walls, RSJs, drainage |
Per-m² rates are for the finished kitchen — units, worktops, appliances, tiling, flooring, electrics and plastering — based on the kitchen's floor area. London and the South East typically sit 20–30% above these figures.
What each tier actually buys
The per-m² figure is really a proxy for specification. At the budget tier you are keeping the existing layout, fitting flat-pack or entry trade units, laminate worktops and freestanding appliances, with minimal replastering. The mid-range tier — where most UK renovations land — brings rigid-built units, a solid or quartz-effect worktop, integrated appliances, new flooring and a part rewire. The high-end tier adds bespoke or in-frame joinery, natural stone or thick quartz, premium appliances, and often a moved or opened-up layout. Two kitchens of the same size can differ by £25,000 purely on these choices, which is why a per-m² rate only means something once the spec is pinned down.
Where the money goes
| Element | Share of budget | Notes |
|---|---|---|
| Units and cabinetry | 30–40% | Flat-pack vs rigid vs bespoke is the biggest lever |
| Worktops | 10–20% | Laminate to quartz to natural stone |
| Appliances | 10–20% | Freestanding vs fully integrated |
| Labour (fitting, trades) | 20–30% | Fitter, electrician, plumber, plasterer, tiler |
| Flooring, tiling, decoration | 10–15% | Rises with large-format tiles or engineered wood |

Is a kitchen renovation worth it?
A kitchen sells a home more than almost any other room, so up to your street's ceiling price a mid-range renovation is usually money well spent — it both improves daily life and supports the sale value. Spending into the high-end tier is a lifestyle decision: worth it for a forever home, but rarely recovered in full at resale if you are moving within a few years. The clearest waste is over-improving — fitting a £40,000 kitchen into a home whose local market caps well below what that implies. Match the tier to how long you will stay and to the value of the street, not to the showroom.
How to bring the per-m² rate down
- Keep the layout — moving the sink, hob and walls is where budgets balloon. A same-footprint refit stays in the lower tiers.
- Mix the spec — splurge on the worktop and handles that you touch daily, save on carcasses hidden behind doors.
- Standard unit sizes — bespoke joinery is beautiful but multiplies the per-m² rate; standard modules with a good fitter get you 90% of the look.
- Get 3 like-for-like quotes — on the same plan and spec, so you are comparing the same job rather than different scopes.
Regional price differences
| Region | Against UK average |
|---|---|
| London | +20–30% |
| South East and Southern | +10–20% |
| Midlands and Eastern | Around the average |
| North West, Yorkshire, North East | −5–15% |
| Wales and Scotland | −5–15% |
A 12m² mid-range kitchen at £22,000 in the North East can pass £28,000 in outer London for the same specification. Judge any quote against local rates — our kitchen renovation cost guide and kitchen refit per-m² comparison break the bands down further.
Choosing the fitter: checklist
- Two recent kitchen renovations you can visit or phone about at a similar spec to yours.
- A Part P registered electrician (NICEIC or equivalent) for the rewire, and a Gas Safe engineer if the hob or boiler moves.
- £2m+ public liability insurance, verified, and a written workmanship guarantee.
- An itemised quote splitting units, worktops, appliances and labour so you can compare like for like.
- Three quotes on the same plan and spec so the per-m² numbers are genuinely comparable.
Red flags
- A single lump-sum price with no split between units, appliances and labour.
- No Part P electrician or Gas Safe engineer named where the wiring or gas is moving.
- A per-m² rate far below £1,000 at "finished" spec — something is missing from the scope.
- Large cash deposits or VAT-free offers with no written contract.
