Length of the base-unit run.

Measure along the wall, including the run under the sink and hob. A corner unit costs the same per unit of run but holds much less, which is the real reason a galley kitchen stores more than an L of the same length.

Carcass, door, drawer and fitting per linear metre.

This rate is per linear METRE of run and carries no dimension, so it stays exactly as typed, while the run length above does follow the unit toggle and switches to the imperial length unit for a US visitor. US price books quote fitted cabinetry per linear foot, and one metre is 3.28084 times that length: multiply a per-foot rate by 3.28084 before entering it, so 200 per linear foot becomes 656 per metre — this page's own example rate, 650 per metre, is 198.12 per foot. Type the per-foot number in unconverted and the cabinetry line comes out 3.28084 times too small: a 20-foot run is stored as 6.096 m, and 6.096 × 200 = 1,219 against the 4,000 that run really costs, an under-report of 69.5%. Nothing warns you, because every realistic cabinet rate falls inside this field's 0 to 100,000 range and is accepted exactly as typed. The wall cabinet rate below works the same way.

Length of the wall-unit run.

The run of WALL units only, measured along the wall they hang on — base units are entered separately because they cost more per metre and carry the worktop. Leave out the gaps: an extractor, a window or a tall unit interrupt the run and are not wall cabinets. Where wall units turn a corner, the corner unit belongs to one leg and not to both.

Typically 55-65% of the base rate.

Wall units cost less per metre of run than base units — no worktop over them, fewer drawers, a shallower carcass — which is where the 55-65% rule of thumb comes from. Price them from your own quote where you can rather than deriving them from the base rate. This field wants the rate PER METRE of run whichever unit system the page is set to: it carries no unit of its own, so it stays exactly as you typed it, while the run length above it does follow the toggle. A US price book quotes cabinetry per linear foot, and one foot is 0.3048 m exactly, so the 380 per metre in this field's own example is 115.82 per linear foot. Type 115.82 here and the wall-cabinet line comes out at 30.48% of what it should be — a 69.52% under-report, about 1,057 short on a 4 m run at that rate — and 115.82 sits well inside the 0 to 100,000 range, so it is accepted in silence. Multiply a per-linear-foot rate by 3.28084 before entering it.

Worktop area.

Include the island. Stone worktops are templated after the cabinets are fitted, which is a scheduling constraint as much as a cost one — the kitchen sits unusable for one to three weeks.

Including template, cutouts and fitting.

THIS RATE IS PER SQUARE METRE AND THE UNIT TOGGLE DOES NOT REACH IT. There is no dimension for a price per unit area, so the number stays exactly as typed, while the worktop area directly above it IS dimensioned — switch the page to US units and that box changes unit while this one does not. A US quote for a worktop supplied and fitted is priced per SF, a square of one foot on a side, and 1 m² is 10.7639 of them (1 / 0.09290304 exactly), so a per-SF price has to be multiplied by 10.7639 before it goes in here: the 420 per m² this page offers as its example rate is 39.02 the other way round. Typing the smaller number is neither refused nor flagged — 39.02 sits inside this field's 0 to 100,000 range, so it is silently ACCEPTED rather than clamped to a bound, and the range is far too wide to catch a worktop price in either denominator. The worktop line is simply the area multiplied by this rate, so it comes back at 9.29% of what it should be whatever the area is, and the contingency, being a percentage, shrinks with it: the worktop all but disappears from the breakdown while the total still reads as a plausible kitchen.

Everything you are buying, as one figure.

One number for the appliances, because their spread is wider than anything else in a kitchen and an average would mislead in both directions. Include what has to be bought and not what is being reused, and remember the ones that are easy to forget: extractor, sink and tap, waste disposal, and the integrated housings a built-in appliance needs. Installation of a gas hob or a new electrical circuit is trades work and belongs in the lines below.

The work behind the walls.

New circuits, moving a waste, capping and reconnecting gas, extract ducting. This is the part nobody sees and the part that is genuinely difficult to change later — it is worth spending here in preference to on doors.

Everything after the units are in.

Flooring, tiling, decorating and the making-good that follows a kitchen — the work that happens once the units are fitted and that people leave out of a kitchen quote because the kitchen company does not do it. On a room being replaced rather than built new, this line also carries the repairs that appear when the old kitchen comes off the wall.

Kitchens hide more than most rooms.

Fifteen percent minimum. Removing old units routinely exposes damaged plaster, undersized wiring, a waste that runs the wrong way, or a floor that is nowhere near level — and all of it is discovered on the day the units arrive.

What this calculation does not cover

  • Excludes structural work — removing a wall, forming an opening, or moving a soil stack are separate and much larger items.
  • Excludes the cost of living without a kitchen, which on a long fit is a real expense people do not budget for.

Frequently asked questions

Where should the money go if the budget is tight?
Into the services and the worktop, and away from the doors. Wiring, waste runs and extract ducting are buried behind and under everything else, and changing them later means taking the kitchen out again. Cabinet doors, by contrast, unscrew — a carcass with cheap doors can be transformed in a weekend in five years' time. The breakdown shows the cabinetry share so you can see which way your budget leans.
Why is 15% contingency the minimum here?
Because a kitchen strip-out is one of the most reliable generators of unwelcome discoveries in domestic work. Behind the units you find damaged plaster, a circuit that will not take an induction hob, a waste running the wrong direction, and a floor that is 20 mm out across the room. None of it is visible while the old kitchen is standing, and all of it is found on the day the new one is delivered.
Does this include taking the wall down?
No, and that is deliberate. Structural work — forming an opening, inserting a beam, moving a soil stack — belongs in its own budget with its own design fees and sign-off. Folding it into a kitchen figure is how a £20,000 kitchen becomes a £55,000 project without anyone noticing where it happened.
Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction.
