Working With Kitchen Fitters: Costs, Process and Getting It Right

What a Kitchen Fitter Actually Does

A kitchen fitter is a specialist carpenter or joiner who takes a designed kitchen layout and physically builds it in your home. They strip out the old kitchen, assemble and install base units, hang wall units, position tall housings, fit worktops, install sinks into cut-outs, secure integrated appliances and complete the finishing work including plinths, cornices, handles and silicone seals.

What most homeowners do not realise until they start getting quotes is that a kitchen fitter, working within their core carpentry qualification, does not do everything. Gas connections must be carried out by a Gas Safe registered engineer. New electrical circuits fall under Part P of the Building Regulations and must be done by a registered electrician. Rerouting water supply pipes and waste runs is plumbing work. Plastering over cable chases requires a plasterer. Tiling the splashback is typically a separate trade. A single kitchen renovation involves five or six different trades, and the fitter is the one who coordinates them all.

This is why the distinction between a sole-trader kitchen fitter and a full-service kitchen installation company matters. A sole-trader fitter handles the carpentry and you organise the other trades yourself. A full-service company manages the entire project, bringing in certified plumbers, electricians, Gas Safe engineers and tilers as part of a coordinated programme. The headline cost is higher but the scheduling, quality control and accountability sit with one company rather than being split across five separate contractors.

The Correct Installation Sequence

The order in which trades follow each other during a kitchen installation is not flexible. Each stage depends on the previous one being complete, and getting the sequence wrong causes rework, damage and delay. This is the standard programme.

Phase 1: Strip-Out (1–2 Days)

Isolate gas, water and electricity at source. Remove old units, worktops, appliances and flooring if it is being replaced. This requires a plumber or Gas Safe engineer to disconnect gas and water safely, and an electrician to isolate circuits. The strip-out reveals the condition of the walls, floor and services behind the old kitchen.

In Manchester’s Victorian and Edwardian terraces, strip-outs frequently expose rising damp, failed damp-proof courses, blown lime render and outdated lead pipework. Solid brick walls without cavities can hold moisture that was hidden behind the old units for decades. Any damp, structural cracking or evidence of woodworm must be treated before first fix begins. Budget a contingency of 10 to 15 per cent for issues discovered at this stage. Strip-out waste including old units, worktops and appliances should be segregated for recycling where possible. Plasterboard must be recycled separately (gypsum produces hydrogen sulphide in landfill), metal fittings go into mixed metal skips, and a licensed waste carrier (with CBDU number) is required for any off-site disposal.

Phase 2: First Fix Plumbing and Electrics (2–3 Days)

The plumber extends or reroutes supply pipes and waste runs to the new appliance positions. New pipework for the sink, dishwasher, washing machine and any plumbed fridge-freezer is run and left capped. The electrician marks out and cables new socket positions, runs dedicated circuits for the oven and hob (typically 32A or 45A), cables under-unit and plinth lighting, and positions the extractor fan connection. All cables are left with tails capped, ready for second fix.

Under Part P of the Building Regulations, any new electrical circuit in a kitchen must be installed by an electrician registered with a government-approved Competent Person Scheme (NICEIC, NAPIT, ELECSA) or separately notified to Building Control. On completion, the homeowner receives an Electrical Installation Certificate and a Building Regulations Compliance Certificate. Missing Part P certification creates a legal defect that surfaces during property conveyancing.

Phase 3: Plastering (1–2 Days)

Skim repairs or full replaster over cable and pipe chases. Fresh plaster needs a minimum of three to five days to cure in normal conditions before units can be fitted against it. In winter or with poor ventilation, drying can take up to two weeks. Fitting units against damp plaster causes moisture damage to carcasses and prevents a clean finish. Do not rush this stage.

Phase 4: Flooring (1–2 Days)

Flooring is ideally installed before base units go in, not after. This allows integrated appliances to be removed easily in future without disturbing the floor, and it avoids the need to cut flooring around unit legs. Screed, levelling compound or board substrate goes down first if needed, followed by the finished floor (LVT, engineered wood, porcelain tiles or vinyl). If you choose to fit flooring after units, the fitter needs to know the final floor height to set unit legs at the correct level.

Phase 5: Unit Installation (2–4 Days)

This is the kitchen fitter’s core work. Base carcasses are assembled (if flat-pack), positioned, levelled and secured. Cross-rails and cabinet connectors link units together. Wall units are hung level and at the correct height relative to base units and tall housings. Filler panels, end panels and appliance housings are positioned and trimmed to fit.

Getting the first base unit level and plumb is critical. A 5mm error at unit one compounds across the run. By unit eight, you can have a 30mm gap that no amount of filler will disguise. Professional fitters use laser levels and spend time getting the first unit perfect before moving on.

Phase 6: Worktop Installation (1–2 Days)

Laminate and solid wood worktops are cut and fitted on site by the kitchen fitter on the day. Joints are sealed, sink and hob cut-outs are routed, and edging is applied. A competent fitter with a router and worktop jig produces clean, professional results.

Stone and quartz worktops follow a different process entirely. A templater visits after units are installed and creates a precise full-scale replica of the worktop layout using corex sheets or laser measuring tools. All dimensions are taken from the actual installed units, not from the kitchen design drawings. This is why templating always happens after unit installation, not before. Even a few millimetres of variation between the design and the reality would produce a worktop that does not fit.

After templating, the stone is fabricated at the workshop. Lead time is typically seven to fourteen working days depending on the fabricator and finish. The fabrication team returns to install the finished worktops, which typically weigh 25 to 80 kg per metre run and require specialist lifting equipment. For a comparison of worktop materials and UK pricing, see our guide to kitchen worktops.

Phase 7: Tiling and Splashbacks (1–2 Days)

Tiling always happens after worktops are fitted. Wall tiles sit on top of the worktop surface, creating a clean junction. Tiling before the worktop creates an incorrect height reference and leaves a visible gap. For glass or stone splashbacks, a separate templating and fabrication process follows the same pattern as stone worktops. A professional tiler handles this phase.

Phase 8: Second Fix and Finishing (2–3 Days)

The plumber returns to connect the sink and taps, plumb in the dishwasher and washing machine, and test for leaks. The electrician fits socket fronts, switches and light fittings, connects the oven and extractor, and issues the Electrical Installation Certificate. The Gas Safe engineer connects the gas hob or range cooker, tests the pipework and issues a Gas Safe certificate. The cooker hood or extractor fan must achieve a minimum extract rate of 30 litres per second (intermittent) or 13 litres per second (continuous) under Part F of the Building Regulations. Ducted extraction to an external wall is always preferable to recirculating carbon filters for moisture and grease removal.

The kitchen fitter completes the finishing work. Door alignment checked, drawer runners adjusted, soft-close mechanisms tested. Silicone sealed around the worktop-to-wall junction and around the sink. Handles fitted, plinths clipped in, cornices and pelmet boards secured. A thorough snagging walk-through identifies anything that needs attention before the final payment.

What It Costs

Kitchen Fitter Day Rates

The UK national average day rate for a kitchen fitter is approximately £200 per day, with a typical range of £140 to £325 depending on experience and location. In Manchester and Greater Manchester, rates sit at approximately £205 per day, very close to the national average and roughly 11 per cent lower than London (£230 per day).

For a full kitchen installation, most professional fitters quote a fixed price per job rather than working on a day rate. A fixed quote gives you cost certainty and includes the fitter’s contingency for unforeseen complications. Day rates work better for smaller, clearly defined jobs (replacing a worktop, fitting four or five replacement doors) where the scope is straightforward.

Labour Costs by Kitchen Size (Fitter Only)

These figures cover the kitchen fitter’s labour only. They do not include plumbing, electrics, gas, plastering or tiling.

Total Labour Including All Trades

Additional trade costs typically break down as: electrician (first and second fix) £500 to £1,900, plumber £300 to £1,000, plasterer £400 to £750, tiler £150 to £250 per day, flooring installer £500 to £1,000. In Greater Manchester, total project labour runs roughly 10 to 15 per cent below London and the South East.

How to Prepare Before Your Fitter Arrives

The single biggest cause of delay in kitchen installations is materials not being on site when the fitter arrives. If you are using a full-service kitchen installation company the project manager coordinates all trades and deliveries. If you are managing the project yourself and hiring a sole-trader fitter, every item on this checklist is your responsibility. Either way, the preparation must be complete before unit installation begins.

Kitchen units delivered and checked. Open every box before the delivery team leaves if possible. Sign the delivery note as “DAMAGED” or “UNCHECKED” if you cannot inspect everything immediately. Check the delivery against your order invoice — count units, verify colour and finish codes, check hinge types (soft-close versus standard), confirm worktop edge profiles. Under the Consumer Rights Act 2015 you have 30 days to reject goods for a full refund. Common missing items include end panels, filler strips, corner posts, screw packs, handles and plinth clips.

All appliances on site. Integrated appliances (oven, dishwasher, fridge) must be on site before fitting begins. The fitter needs their exact physical dimensions to build the housings correctly. Do not rely on the appliance box dimensions. Measure the appliance itself.

First fix plumbing and electrics complete. Pipes and cables must be in position with tails capped. Walls must be plastered and fully dry. Starting unit installation against damp plaster or with incomplete services behind the wall creates problems that are expensive to fix later.

Temporary kitchen set up. For a medium kitchen installation, expect five to ten working days without a fully functional kitchen. Set up a kettle, microwave, toaster and cold water access in another room.

DIY Kitchen Fitting vs Professional

A competent DIYer can realistically assemble flat-pack carcasses, fit base and wall units in a straightforward layout, fit laminate worktops using a jigsaw and worktop jig, hang cabinet doors, adjust soft-close hinges, and fit plinths, cornices and handles. For a simple galley kitchen with laminate worktops and no layout changes, a skilled DIYer can save £700 to £1,000 in fitter labour.

What you cannot legally do yourself:

Gas connections. Connecting a gas hob, oven or range cooker without Gas Safe registration is a criminal offence under the Gas Safety (Installation and Use) Regulations 1998. It also voids your home insurance. A Gas Safe engineer charges £80 to £150 for a hob connection and certificate.

New electrical circuits. Any new circuit, consumer unit modification or new fixed appliance connection in a kitchen falls under Part P. A registered electrician must install, test and certify the work. Expect £500 to £1,900 depending on the scope.

Stone worktop installation. Not a regulatory issue but a practical one. Quartz and granite worktops weigh 25 to 80 kg per metre run, require diamond cutting tools and specialist lifting equipment. This is fabricator-team work, not a DIY task.

Common DIY Mistakes

Starting with units out of level (a 5mm error at unit one creates a 30mm gap by unit eight). Using coarse-thread wood screws in MDF carcasses instead of fine-thread euro screws (the screw pulls through under load). Drilling through live cables or pipes when hanging wall units (always use a cable and pipe detector). Tiling before worktops are fitted (tiles must sit on the worktop surface, not behind it). Omitting isolation valves on each appliance supply (meaning you have to shut off the entire house water supply for any future repair).

Finding a Quality Kitchen Fitter

What the Accreditations Mean

BiKBBI / BIFIS (British Institute of Fitted Interiors Specialists) is the UK’s only government-sanctioned institute specifically for kitchen, bedroom and bathroom installation. Members are independently assessed on methodology, compliance, health and safety and customer service. With over 4,600 installation specialists nationally, BiKBBI membership is the most relevant credential specifically for kitchen fitting. Verify membership at bifis.org.

TrustMark is the UK government’s endorsed quality scheme for domestic trades. Members undergo independent technical and financial checks. Cannot be self-joined — requires entry through a licensed Scheme Provider. The most rigorous of the consumer-facing quality schemes.

FMB (Federation of Master Builders) requires trading history and financial stability checks with ongoing auditing. Provides a free dispute resolution service. Verify at fmb.org.uk.

The Guild of Master Craftsmen is a paid membership body without the independent assessment rigour of TrustMark or BiKBBI. It can supplement other credentials but should not be treated as equivalent.

Questions to Ask Before Hiring

Are you BiKBBI, FMB or TrustMark registered? Can I verify your membership number independently? Do you carry public liability insurance (minimum £2 million)? Can I see three recently completed kitchens? What does your quote include and exclude? What is your payment schedule? Who does your plumbing and electrical work, and are they Gas Safe and Part P registered respectively? What guarantee do you provide on labour? Have you worked with this specific kitchen brand before? Will you carry out a pre-fit survey before starting?

A reasonable payment structure is 10 to 25 per cent deposit, staged payments through the build, and 5 to 10 per cent retention held until all snagging is resolved. Never pay 100 per cent upfront. For a professional kitchen fitting quotation tailored to your project, our team provides free consultations covering the full scope of installation work.

Realistic Project Timelines

Stone worktops add seven to fourteen working days of fabrication time after templating. Specialist appliances (range cookers, American fridge-freezers) may have four to eight week lead times. Complex island configurations with waterfall worktop ends, bespoke cabinetry and custom stone splashbacks all extend the programme.
