Three steps to hiring the right kitchen fitter
First, ask to see photos of similar completed jobs. Second, clarify exactly who handles the electrical and plumbing work. Third, get a written quote that separates units, worktop, appliances and labour, so you can see where the money's actually going.
How long does a kitchen refit take?
A worktop or door replacement is usually a day or two. A full kitchen refit including new units, worktop and appliance connections commonly takes 1-3 weeks — worth planning for reduced kitchen access during this time, particularly for cooking arrangements.
KBSA and TrustMark, what they actually mean
The KBSA (Kitchen Bathroom Bedroom Specialists Association) is the main UK trade body for the sector, though membership is limited to a few hundred companies nationally, so not every kitchen fitter will hold it. TrustMark is a broader government-endorsed scheme covering many trades — worth asking which, if either, your fitter holds rather than assuming either is standard.
Common kitchen fitting jobs
Kitchen fitters handle everything from a single worktop or cupboard door replacement to a full gut-and-refit: removing old units, fitting new cabinetry, worktops, and coordinating the plumbing and electrical work a kitchen needs (sink, dishwasher, oven, extractor). Many fitters manage the whole job and bring in a plumber or electrician for specific parts.
Planning bin storage properly
Built-in pull-out bin drawers, sized for recycling separation, are far easier to plan into a layout during a refit than to add afterwards — worth deciding on bin capacity and separation needs (general waste, recycling, food waste) before cabinet layout is finalised, not after.
Gas hobs need a Gas Safe engineer
Installing or moving a gas hob is gas work, same as a boiler, and legally needs a Gas Safe registered engineer, not just a kitchen fitter or general plumber. If you're switching from electric to gas (or vice versa) as part of a refit, this needs coordinating separately from the general fitting work.
Kitchen layout, the "working triangle" and beyond
The traditional advice is to keep the sink, hob and fridge in an efficient triangle so you're not crossing the kitchen constantly while cooking — still a useful starting point, though open-plan and island layouts sometimes work better with a different logic. Worth discussing how you actually use a kitchen day to day, not just the theory.
What affects the cost
Cost depends on worktop material (laminate vs stone vs wood), whether the layout is changing (moving plumbing/electrics vs replacing in place), unit quality, and appliance integration. Moving a sink or hob position adds cost beyond the units themselves because of the pipework and electrical work involved.
