Kitchen Renovation Cost Calculator

Kitchen renovation is typically the single most expensive room in a house to renovate. Kitchen refurbishments run 8,000-40,000+ depending on size, specification, appliances, and structural work. Individual fitted kitchens from major suppliers typically run 5,000-25,000 for units alone, before appliances, worktops, installation, flooring, or decoration.

The main cost componentsunits and worktops (the biggest line, 40-60% of total), appliances (15-25%), installation and trades (15-25%), flooring and finishes (5-15%). Appliance choice dramatically swings the total — built-in appliances from premium brands (Miele, Gaggenau) can exceed 10,000 vs 2,000-3,000 for mid-range freestanding.

Structural work (removing walls, moving services) adds 2,000-10,000+ depending on scope. Open-plan kitchen-dining renovations often hit 25,000-50,000+ because they combine kitchen with living space requirements.

How to use it

Input kitchen size, cost per linear metre of units, appliance budget, labour days, daily rate, and contingency. The tool produces realistic total with breakdown.

What the result means

Total is full renovation cost including units, appliances, and labour. Per-metre metric allows comparison to typical ranges (basic 500-1,500/metre, mid 1,500-3,000, premium 3,000-6,000+). If your number is significantly outside range, either specification is atypical or estimate needs revisiting.

Quick example

With linear metres of units of 8 and cost per linear metre of 1,500 (plus appliance budget of 4,000 and installation days of 10), the result is 21,620.00. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.

Which inputs matter most

You enter Linear Metres of Units, Cost per Linear Metre, Appliance Budget, Installation Days, and Daily Labour Rate. Not every input has equal weight. Adjusting one input at a time toward extreme values shows which ones move the result most.

What's happening under the hood

Sums unit costs (linear metres × per-metre), appliances, labour (days × rate), then applies contingency. The formula is listed in full below. If the number looks off, you can retrace the calculation by hand — that's the point of showing the working.

Why run the numbers before the purchase

Big purchases reward slow thinking. The calculation here is fast; the decision it informs isn't. Running this before you shop is the cheapest way to avoid the "seemed fine in the showroom" trap.

What this doesn't capture

Purchase decisions rarely come down to payback alone. Reliability, time saved, enjoyment, and alternatives outside the calculation all matter. The figure gives you the money side cleanly so you can weigh it against everything else honestly.
