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.
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.
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.
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.
Planning kitchen storage during a refit
Pull-out larders, corner carousel units, and drawer-based (rather than cupboard-based) storage all make better use of available space than standard cupboards, but need planning into the layout from the start rather than added afterwards. Worth discussing storage needs before finalising unit choices.
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.
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.
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.
