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.
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.
What a good kitchen quote should include
A proper quote should specify unit and worktop brand/spec (not just "units, worktop"), whether appliances are supplied or just fitted, whether electrical and plumbing work is covered directly or subcontracted, and what happens if hidden issues are found once old units are removed.
Cabinet handles and hardware, a small but real cost
Handles, hinges and drawer runners are a small line item individually but add up across a full kitchen, and soft-close mechanisms cost more than standard hinges — worth clarifying what's included as standard in a quote versus what's an upgrade, since this varies between fitters.
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.
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.
Planning a kitchen-diner layout
Combining kitchen and dining space needs enough clearance around both the cooking area and the table for comfortable movement, and often benefits from a slightly different lighting and ventilation plan than a standalone kitchen — worth discussing how the space will be used for both cooking and eating before finalising layout.
