Understanding the labour vs materials split
Units, worktop and appliances are often the largest share of a kitchen's total cost, but fitting labour, old kitchen removal, and making good around new services add up too. A cheap quote is worth checking against the same unit/worktop spec as competing quotes, not just lower labour.
Integrated vs freestanding appliances
Integrated appliances (behind matching cabinet fronts) give a more seamless look but cost more and can be more expensive to replace later since they need to match the specific cabinet dimensions. Freestanding appliances are more flexible and often cheaper, at the cost of a less uniform appearance.
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 many quotes should you get?
Three is reasonable for most kitchen jobs. For a full refit, make sure each quote specifies the same unit range and worktop material, since kitchen quotes vary enormously based on spec assumptions that aren't always stated clearly upfront.
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.
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.
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.
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.
