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.
Kitchen plumbing and appliance connections
A new sink, dishwasher or washing machine needs its own isolation valve and a proper waste connection — moving the sink position, in particular, often means new pipework rather than just reconnecting to the old point. Check whether your fitter handles this directly or brings in a plumber.
Food waste disposal units, what to know
An under-sink food waste disposal unit needs its own electrical connection and specific plumbing configuration — not every kitchen sink setup can accommodate one without modification, so it's worth deciding early in the planning rather than as an afterthought once plumbing is first-fixed.
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.
Why an in-person survey matters for kitchens
Walls and floors are rarely perfectly square, especially in older properties, and a survey catches this before units are ordered to a size that won't actually fit cleanly. Skipping a proper survey in favour of a quick estimate is a common cause of on-site problems during fitting.
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.
Making corner units actually usable
A standard corner cabinet often wastes significant depth unless fitted with a proper carousel or pull-out mechanism — worth specifying this upfront rather than accepting a basic corner unit by default, since retrofitting a carousel mechanism later usually isn't practical.
Kitchen lighting layers
A well-lit kitchen usually combines general ceiling lighting, task lighting (under-cabinet lights over worktops, where most food prep happens), and sometimes accent lighting — a single central ceiling light alone often leaves worktops in shadow. Worth planning lighting circuits before, not after, unit installation.
