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.
Kitchen flooring options
Vinyl and laminate are budget-friendly and reasonably water-resistant. Porcelain tile is more durable and higher-end but needs a sound, flat subfloor. Engineered wood looks warmer but needs more care around water near the sink and dishwasher — worth weighing durability against look for how the kitchen is actually used.
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.
Sizing appliances to your household
An oversized fridge-freezer or dishwasher costs more to buy and run than one properly sized to household needs, while an undersized one means more frequent shopping trips or wash cycles. Worth discussing realistic household size and habits with your fitter rather than defaulting to the largest option that fits.
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.
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.
