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.
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.
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.
Kitchen regulations, FAQ
Do I need building control sign-off for a kitchen refit? Usually not for a like-for-like layout, but new electrical circuits need a registered electrician's certification, handled as part of that work. Can I fit my own units? Yes, unit fitting itself isn't regulated — it's the electrics and plumbing behind it that are.
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.
Kitchen electrics need a registered electrician
A kitchen refit usually means new dedicated circuits for higher-draw appliances (oven, hob, dishwasher) rather than sharing a ring main, plus RCD protection near the sink — this is notifiable work under Part P. If your kitchen fitter isn't a registered electrician themselves, ask who handles this part and whether they're NICEIC or NAPIT registered.
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.
First fix and second fix in a kitchen refit
"First fix" is pipework and electrical cabling before units go in; "second fix" is fitting appliances and connecting services once units and worktop are in place. Getting the sequence right avoids having to remove finished units to fix an overlooked service run.
