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.
What affects the cost
Cost depends on worktop material (laminate vs stone vs wood), whether the layout is changing (moving plumbing/electrics vs replacing in place), unit quality, and appliance integration. Moving a sink or hob position adds cost beyond the units themselves because of the pipework and electrical work involved.
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.
Kitchens as part of a wider extension
A kitchen fitted as part of a house extension needs closer coordination between the builder and kitchen fitter on timing — services (electrics, plumbing, ventilation ducting) need to be roughed in during the build phase, before the kitchen fitter's own first-fix stage begins.
Common kitchen fitting jobs
Kitchen fitters handle everything from a single worktop or cupboard door replacement to a full gut-and-refit: removing old units, fitting new cabinetry, worktops, and coordinating the plumbing and electrical work a kitchen needs (sink, dishwasher, oven, extractor). Many fitters manage the whole job and bring in a plumber or electrician for specific parts.
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.
Workmanship guarantees on kitchen fitting
Ask what's covered by a workmanship guarantee specifically — unit installation and worktop fitting should be explicitly included. Appliance manufacturer warranties are separate and worth registering promptly; some require registration within a set period after installation to be valid.
Choosing a kitchen sink and tap
A single, larger bowl is often more practical than a traditional 1.5 bowl for modern dishwasher-owning households. A boiling water tap adds real convenience but needs a dedicated under-sink unit and its own electrical supply — worth deciding early if you want one, since it affects the plumbing and electrical first-fix.
