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.
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.
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.
Kitchen condition and selling your home
A well-maintained, reasonably modern kitchen is one of the strongest factors in buyer appeal, and any electrical certification from work done during a refit is worth keeping for buyers' solicitors. A dated or poorly maintained kitchen is one of the most common things buyers plan to immediately replace.
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.
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.
Red flags in a cheap kitchen quote
A quote well below others is worth questioning — check it specifies the same unit brand/range and worktop material as competing quotes, covers who handles electrical and plumbing work, and includes disposal of the old kitchen.
How kitchen fitting quotes work
Describe the current layout and what's changing — an initial estimate can follow, but a firm price for anything beyond a straightforward like-for-like refit usually needs an in-person visit, since existing plumbing/electrical positions significantly affect cost once work starts.
