Kitchen Cost Calculator

Kitchen costs vary enormously with specification. A budget kitchen of flat-pack units, laminate worktops and basic appliances, the sort sold by Howdens or B&Q, costs £5,000 to £10,000. A mid-range fit-out with solid-wood doors, quartz worktops and integrated appliances from the likes of Wren or Magnet runs £10,000 to £20,000. Premium bespoke cabinetry, natural stone and high-end appliances from Neptune, deVOL or Plain English can exceed £25,000 to £40,000.

Installation is quoted separately and adds £3,000 to £8,000 depending on scope. That covers stripping out the old kitchen, plumbing, electrics including any new circuits an induction hob needs, tiling, plastering and flooring. A full refit takes 2 to 4 weeks, during which the room is out of use. Some of the work has to be notified under Building Regulations, particularly new electrical circuits and any move of the gas supply, which the calculator flags.

Enter your kitchen size, specification level and the scope of work, and the estimate breaks into units, worktops, appliances, plumbing, electrics, tiling and fitting labour. Measured along the wall, a fitted kitchen costs £700 to £3,000 per linear metre once units, worktops and appliances are counted, and the Which? survey put the average British kitchen in 2026 at £12,500 all in. Of that total, units take about 30%, worktops 20%, appliances 25% and installation 15%, with the remaining 10% going on flooring, lighting and plumbing.

Worktops carry more of the look than anything else in the room. Laminate at £25 to £80 per m² is the budget choice, with a life of 8 to 15 years. Solid wood at £80 to £200 is warm but wants regular oiling. Quartz, the most popular premium surface in Britain, costs £200 to £500 and lasts 25 years and more without staining. Granite at £150 to £500 is natural and very hard, though it stains if the sealer lapses, and marble at £250 to £700 is lovely and scratches. Corian and similar solid surfaces at £200 to £500 sand back, while stainless steel at £300 to £600 gives a commercial look.

Appliances add up faster than most budgets allow for. A built-in oven is £300 to £2,000 and beyond, an induction hob £350 to £1,500, an extractor hood £200 to £1,000 and a built-in microwave £200 to £800. An integrated fridge-freezer costs £600 to £2,500, a dishwasher £350 to £1,200 and a washing machine £300 to £1,000. Statement pieces cost more again, with a range cooker at £800 to £8,000, an American-style fridge £800 to £4,000, a wine fridge £400 to £2,500 and a £600 premium for a pyrolytic self-cleaning oven. Bosch, Miele and Neff dominate the mid to premium market, with AGA and Rangemaster for country kitchens.

The costs that break budgets are the ones nobody quotes for. Plumbing alterations for a moved sink or dishwasher run £400 to £1,500. Electrical work covering rewires, extra sockets and lighting is £800 to £3,000. Plastering after the old kitchen comes out is £400 to £1,500, new flooring in tile or LVT £1,500 to £4,000, a splashback £300 to £2,000, lighting £500 to £2,000, decoration £400 to £1,500, and a skip for the old units £200 to £400. Budget 15 to 25% above the quoted price.

There are sensible places to economise. Replacing the doors on existing carcasses costs £1,500 to £3,000 against £8,000 and up for new units. Mid-range Bosch or Whirlpool appliances are reliable at a fraction of Miele or Gaggenau prices. LVT flooring looks like wood at 30 to 50% of the cost, and B&Q LED downlights at £5 to £15 do the same job as designer fittings at £50. Put the saved money into worktops, the sink and taps, flooring and door handles, because cheap handles make an expensive kitchen look cheap.
