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.
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.
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.
Planning bin storage properly
Built-in pull-out bin drawers, sized for recycling separation, are far easier to plan into a layout during a refit than to add afterwards — worth deciding on bin capacity and separation needs (general waste, recycling, food waste) before cabinet layout is finalised, not after.
Kitchen layout, the "working triangle" and beyond
The traditional advice is to keep the sink, hob and fridge in an efficient triangle so you're not crossing the kitchen constantly while cooking — still a useful starting point, though open-plan and island layouts sometimes work better with a different logic. Worth discussing how you actually use a kitchen day to day, not just the theory.
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.
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.
