Kitchen renovation cost in London (2026): the two levers that set the price

A kitchen renovation in London costs somewhere between £16,000 and £125,000 in 2026, and two decisions set most of that range: what your cabinetry is made of, and whether you move the layout. Get those two right and the rest of the budget — worktops, appliances, tiling, decoration — falls into a predictable band around them. This guide gives you the cost tiers organised by how the cabinetry is built, a plain map of where the money is worth spending and where it isn't, and the two things that quietly add the most: a structural opening, and the services nobody sees.

The two levers, before anything else

Spend a minute here and the price stops being a mystery.

Lever one is the cabinetry. The carcasses and doors are the largest single slice of almost any kitchen, and they range from flat-pack chipboard you assemble, through factory-built melamine units, up to real-timber fronts on a stock carcase, to fully made-to-measure joinery. That one choice can swing the bill by tens of thousands on its own.

Lever two is whether the layout moves. Keep the sink, the run and the appliances broadly where they are and you save on plumbing, waste, electrics and — crucially — structural work. Open the kitchen into the next room or out to the garden and you've added a wall removal, a steel beam, building control, and usually a doubling of the flooring area. Same cabinets, very different total.

Everything below hangs off those two.

Cost tiers, by how the cabinetry is built

Organising by cabinetry construction tells you more than a bare price band, because that's the part that lasts (or doesn't):

• Flat-pack carcasses, same layout — £16,000–£26,000. Self-assembly or trade-supplied chipboard units, laminate or entry quartz tops, mainstream integrated appliances, existing floor kept. Fast to fit. The right call for a rental or a sound layout you simply want renewed.
• Factory-built units, same layout — £26,000–£42,000. Made-to-order melamine cabinetry, engineered-stone worktops, upgraded appliances, proper integrated lighting, new flooring. A finished, durable kitchen without going bespoke.
• Real-timber doors or bespoke joinery, often with a layout change — £42,000–£62,000. In-frame or Shaker fronts in solid wood on a sturdy carcass, natural stone or top-tier quartz, better appliances, frequently a structural opening and a full re-service. Where most "forever kitchen" briefs land.
• Design-led, fully bespoke, often extended — £62,000–£125,000+. Cabinetry built to the room, premium appliances, rare stone, rooflights, underfloor heating and structural work to open the plan. The limit is the brief, not the building.

Each band is a 2026 London figure for materials plus labour, pinned down at the survey.

Where to spend, where to save

If the budget is finite — and it usually is — here's the honest steer:

Spend on the things you touch and the things you can't redo cheaply: the carcass quality (a sagging chipboard box in ten years undoes everything above it), the worktop, the drawer runners and hinges, the tap, and the layout itself. These are daily-contact items and structural decisions; getting them right is what makes the kitchen feel expensive long after fitting.

Save, sensibly, on the things that are easy to upgrade later or that nobody clocks: door fronts can be painted rather than sprayed in some ranges, a mid-range integrated appliance often does the same job as a badge that costs three times more, and a handsome porcelain can stand in for stone on a splashback. The trap is the reverse — pouring the budget into a statement worktop sat on weak cabinetry, or a wall of premium appliances in a layout that never worked.

The structural opening — the line people underestimate

Opening the kitchen into the next room or knocking out the rear wall is where a "kitchen" quietly becomes a building project. In a London terrace the back or spine wall normally carries load, so taking it out means a structural engineer sizing a beam, the beam propped while the wall comes down, padstones bedded in the walls that remain, and building control inspecting before anything is boarded over. Budget £4,200–£8,500 to cover engineering, steel and installation for a typical internal opening, and remember the knock-on: when two rooms become one, the new floor normally has to run through both, which doubles the flooring quantity. If the steel lands in a party wall, your neighbour has to be notified first under the party-wall rules.

Services and ventilation — the invisible costs

Three services items catch people out because they don't show in the finished room:

• Electrics. A new kitchen almost always needs an added circuit and a dedicated supply for the oven; any new circuit is notifiable under Part P and must be certified. Plan it at first fix — rewiring once units are in is slow and expensive.
• Gas and the meter. Moving a gas hob's position is regulated work for the right registered engineer, notified to building control; switching to induction simply caps the old gas point. Relocating a gas meter or the distribution board brings supplier and (in flats) freeholder charges.
• Ventilation. A ducted extractor vented outside clears moisture and smell; a recirculating hood — often the only option in a flat with no external duct route — does neither well. Settle the route before the units are designed in.

How the price is locked

The surest way to end up paying for a kitchen twice is a change of heart mid-build. So the spec is fixed before a tool moves: the design signed off, the appliance list closed, the worktop confirmed, the flooring chosen, and the lead times — anything from a fortnight for flat-pack to three or four months for bespoke joinery — built into the programme so nothing arrives late. We quote it broken to trade level, agree the dates in advance, and keep one point of contact across the whole job. Any change after sign-off is priced and agreed on paper first, so the figure you approved is the figure you pay.

Closing CTA

A kitchen price turns on the cabinetry, the layout and what the walls are carrying — none of which can be judged down a phone line. PrimeCraft Surface Solutions surveys the space, gets an engineer's view on any opening, and returns a trade-level quote that separates the cabinetry, the worktops, the appliances and the structural work, so every pound is visible and any line can be trimmed.
