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.
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.
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.
Knocking through for an open-plan kitchen
Removing a wall between a kitchen and adjoining room to create an open-plan space is a structural job, not just a kitchen fitting one — it needs a structural engineer's assessment and, if the wall is load-bearing, a supporting beam, plus building control sign-off. This is usually coordinated with, not done by, the kitchen fitter directly.
Kitchen ventilation and extraction
An extractor hood vented to the outside removes cooking odours and moisture more effectively than a recirculating (filter-only) hood, but needs ducting planned into the layout — easier to arrange during a full refit than retrofit afterwards. Building Regulations require adequate ventilation in kitchens generally.
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.
Aftercare after a kitchen refit
Keep electrical certification (for new circuits) and appliance warranties together with your kitchen paperwork. Check cabinet doors and hinges after a few months of use and re-adjust if needed — a normal part of settling in that most fitters will do free of charge shortly after completion.
What a good kitchen quote should include
A proper quote should specify unit and worktop brand/spec (not just "units, worktop"), whether appliances are supplied or just fitted, whether electrical and plumbing work is covered directly or subcontracted, and what happens if hidden issues are found once old units are removed.
