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 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.
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.
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.
Common kitchen fitting myths, busted
"A bigger kitchen always costs proportionally more" — layout complexity and worktop material often matter more than raw size. "Flat-pack units are always lower quality" — carcass quality varies more by brand than by whether it's flat-pack or pre-assembled. "You need to replace everything to update a kitchen's look" — new doors and worktop alone can transform an existing layout.
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.
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.
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.
