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 electrics need a registered electrician
A kitchen refit usually means new dedicated circuits for higher-draw appliances (oven, hob, dishwasher) rather than sharing a ring main, plus RCD protection near the sink — this is notifiable work under Part P. If your kitchen fitter isn't a registered electrician themselves, ask who handles this part and whether they're NICEIC or NAPIT registered.
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.
Kitchen fitting in older properties
Older properties sometimes have uneven floors and walls, or original chimney breasts and alcoves that affect standard unit layouts — a fitter working on a period property will usually survey these carefully before quoting, since standard-width units don't always fit cleanly into non-standard spaces.
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.
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.
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.
Respraying or painting existing units
Professionally sprayed cabinet doors can refresh a kitchen's look at a fraction of full replacement cost, provided the existing doors are a suitable material (solid wood or properly primed MDF, not all laminates take a respray well) — worth asking a fitter to assess suitability before committing either way.
