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.
Registering appliance warranties promptly
Many appliance manufacturers require warranty registration within a set period (often 30-90 days) after installation to be valid — worth doing this as soon as appliances are fitted rather than assuming purchase alone activates the warranty automatically.
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.
Background checks and identity verification
Since kitchen fitting isn't gated by a single mandatory certification, checking trading history, a verifiable business address, and reviews referencing specific completed jobs matters more here than for trades with a clear registration body.
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.
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.
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.
Adding a kitchen island, what to consider
An island needs enough surrounding clearance to be usable (not just fit), and if it includes a sink or hob, plumbing and electrics need to reach it — often via the floor, which is far easier to plan during a full refit than retrofit into an existing floor later.
