What Paperwork Do You Need for a Kitchen Fit?
Kitchen installations still need paperwork tailored to the work. Here is everything you need — from Part P electrics and Gas Safe certificates to COSHH, RAMS, and insurance.
TL;DR
- • Part P applies to domestic electrical work, but only specified work is notifiable. England and Wales have different kitchen rules; check the job and keep the right certificates.
- • Any gas work (cooker, hob, boiler) must be done by a Gas Safe registered engineer. Working on gas without registration is a criminal offence.
- • Assess COSHH risks where adhesives, grouts, epoxies, cleaning products or cutting dust could expose people to hazardous substances.
- • Construction work on a domestic kitchen needs a proportionate CPP; assess the work risks and check whether the client or site asks for written RAMS.
- • Public liability cover is generally voluntary but often requested. Employers’ liability is generally required where you have staff, subject to exemptions.

Why does a kitchen fit need paperwork?
Kitchens are one of the most common jobs for tradespeople in the UK, and many fitters treat them as straightforward domestic work that does not need much in the way of documentation. That is a mistake. A kitchen fit routinely involves electrical work that may need notification, gas connections, plumbing alterations, and the use of hazardous substances — all of which come with legal paperwork requirements.
Beyond the legal requirements, proper paperwork protects you commercially. If a homeowner sells their property and the conveyancer asks for the electrical, gas or building-control records that apply to the work, and they do not exist, the homeowner will come looking for you. If a worktop joint fails because the adhesive was not suitable and you have no COSHH assessment or method statement showing how it was installed, you are exposed. If someone trips over your tools in the client’s hallway, you may face a claim and unexpected costs.
The good news is that the paperwork for a kitchen fit is not complicated. Most of it is lightweight, and much of it is produced by the specialists you bring in (electricians, gas engineers). Your job as the kitchen fitter is to make sure it all gets done, collected, and handed over. Think of it as the professional standard that separates a proper kitchen company from someone selling units out of the back of a van.
What are the electrical regulations for a kitchen fit?
Domestic electrical work falls under Part P of the Building Regulations in England and Wales. Notification rules differ between the two countries; Scotland and Northern Ireland have separate regimes. Work on circuits and appliances must still be safe even when building-control notification is not required.
In England, the following Part P work is notifiable. A registered competent-person electrician can self-certify it; otherwise arrange building-control approval before work starts:
- Installing a new circuit — for example, a dedicated cooker circuit, a new ring main for worktop sockets, or a circuit for under-cabinet lighting.
- Replacing or upgrading the consumer unit (fuse board).
- Adding to or altering an existing circuit in a specified special location, such as the area around a bath or shower or a room containing a swimming pool or sauna heater. A kitchen sink is not a special location in England.
Wales has wider kitchen notification rules: extending an existing circuit in a kitchen can be notifiable. Its Approved Document P uses 3 metres from a sink only as a guide to the boundary of an open-plan kitchen, not as a universal notification zone. Check the Welsh rules for the particular job.
Replacing a socket like for like, or connecting an appliance to an existing point without a new circuit, may be non-notifiable. All electrical work still needs appropriate safety checks. A registered electrician can issue the relevant Electrical Installation Certificate or Minor Works Certificate; for notifiable work, obtain the separate Building Regulations compliance record through their scheme or building control.
For a deeper look at electrical risks on site, see our electrical safety guide.
When do you need a Gas Safe engineer?
Any work on a gas installation — including pipework, appliances, and flues — must be carried out by a Gas Safe registered engineer. This is a legal requirement under the Gas Safety (Installation and Use) Regulations 1998. Working on gas without registration is a criminal offence that carries an unlimited fine and up to two years in prison.
In a kitchen fit, you are likely to need a Gas Safe engineer for:
- Removing or reinstalling a gas cooker or hob as part of the refit, beyond a temporary move to clean its usual space.
- Capping off a gas supply pipe during the fit-out period.
- Reconnecting or commissioning a gas cooker, hob, or oven in the new kitchen.
- Moving or extending a gas supply pipe to a new appliance location.
- Installing, moving, or reconnecting a gas boiler if the boiler is within the kitchen.
Ask the Gas Safe engineer which work record or Building Regulations Compliance Certificate applies to the job. A compliance certificate is issued for gas work that must be notified, not for every gas connection. Keep any documents issued with the project file and give the homeowner a copy. Plan the engineer’s visit around the kitchen programme.
HSE says temporarily moving a freestanding cooker with a bayonet fitting to clean the space it normally occupies is not gas work under these regulations. Installation or reinstallation as part of a kitchen refit is gas work for a Gas Safe registered engineer. If the job goes beyond that narrow temporary move, check with the engineer before work starts.
What plumbing and waste paperwork do you need?
Domestic plumbing in England and Wales has no single blanket certification scheme. An approved contractor who installs, alters, connects or disconnects a water fitting must provide a signed compliance certificate under regulation 6 of the Water Supply (Water Fittings) Regulations 1999. The Water Supply (Water Fittings) Regulations 1999 set requirements for all plumbing installations to prevent contamination of the water supply, and some plumbing work is notifiable to the local water company.
Regulation 5 lists work that needs advance notice to the water undertaker, including a bidet with an ascending spray and certain water-treatment equipment, garden-watering systems and outside pipework. An ordinary outside tap or every new kitchen connection is not automatically notifiable. Check the exact fitting and any approved-contractor exemption before work starts. Moving a sink or connecting appliances still requires compliant fittings and backflow protection.
Waste connections must comply with Part H of the Building Regulations. For a kitchen fit, this mainly means ensuring that the sink waste, dishwasher waste, and washing machine waste are properly connected to the drainage system with appropriate traps and gradients. If you are moving the waste run significantly — for example, relocating the sink from one wall to another — you may need to run new pipework through the floor void or along the wall, and building control may want to inspect this if the alteration is substantial.
In Scotland, plumbing work falls under the Scottish Water Byelaws, and Scottish Water requires notification for specified work under Byelaw 5. Check the applicable byelaw and the property’s water supply.
What COSHH assessments do kitchen fitters need?
COSHH — the Control of Substances Hazardous to Health Regulations 2002 — requires you to assess the risks from every hazardous substance your team uses on site and put controls in place to protect their health. Kitchen fitting involves more hazardous substances than most people realise.
Silicone sealants
Most silicone sealants release acetic acid vapour during curing (the vinegar smell). In a small, enclosed kitchen with poor ventilation this can cause eye and respiratory irritation. Many kitchen and bathroom sealants also contain fungicides. Your COSHH assessment should specify adequate ventilation during and after application, and gloves to prevent skin sensitisation from prolonged contact.
Tile adhesives and grouts
Cement-based tile adhesives and grouts contain Portland cement, which is a well-known skin sensitiser. Prolonged or repeated skin contact can cause allergic contact dermatitis — a condition that is permanent once developed. Your COSHH assessment should require gloves (nitrile, not latex), long sleeves, and eye protection when mixing. Dust from mixing powdered adhesive requires an FFP2 mask.
Contact adhesives and epoxies
Worktop joints are typically bonded with two-part epoxy or colour-matched sealant. Some worktop installers use contact adhesive for edging strips. These products contain solvents, hardeners, and resins that can cause skin sensitisation, respiratory irritation, and in some cases occupational asthma. Check the safety data sheet for each product and specify the appropriate PPE.
Cutting dust
Cutting laminate, MDF, or solid timber worktops generates wood dust, which is a workplace exposure limit (WEL) substance. MDF dust in particular contains formaldehyde and is classified as a respiratory sensitiser. Cutting stone, quartz, or porcelain worktops generates silica dust — a cause of silicosis, a serious and irreversible lung disease. Your COSHH assessment should specify wet cutting or dust extraction for all worktop cutting, and RPE (minimum FFP3 for silica dust) where extraction alone is insufficient.
For a comprehensive guide to COSHH obligations, see our COSHH for builders guide.
Do you actually need RAMS for a kitchen fit?
The short answer is: assess the risks first. Employers and self-employed contractors must assess relevant health and safety risks and put suitable controls in place. A kitchen fit involves power tools, electrical work, potential gas work, heavy manual handling, hazardous substances, and work in an occupied domestic property. That qualifies as significant risk.
If you are working for a commercial client — a housing association, a local authority, a property management company, a hotel chain, a restaurant group — the client may require written RAMS before site access. Check the contract and site rules. If you are fitting kitchens for a housebuilder or a principal contractor, CDM 2015 requires you to plan, manage and monitor the health and safety of your work. Written RAMS can help explain those arrangements where the client or principal contractor asks for them.
Even on domestic jobs, having RAMS is good practice. It does not need to be a 30-page document. Use a proportionate assessment of the actual hazards (electrics, gas, manual handling, substances and work in an occupied home). A short method statement can help brief the team on the work sequence; a signed RAMS document is not a universal legal requirement.
If your kitchen fitting company works with housing associations, student accommodation providers or care homes, clients may ask for RAMS that describe the actual kitchen work and site conditions. For more on what RAMS involves, see our guide to RAMS.
Do you need a construction phase plan for a kitchen?
Yes. In Great Britain, CDM 2015 requires a CPP for construction work, including a kitchen fit. Regulation 12(1) makes the principal contractor responsible where more than one contractor is involved; regulation 15(5) covers the only contractor on a single-contractor job. There is no size exemption, but a small kitchen plan can be proportionate. Northern Ireland has separate CDM 2016 rules.
A lightweight CPP for a kitchen fit should cover:
- A brief project description — the property address, the scope of work, the expected duration, and the key dates.
- The significant hazards — electrics, gas, manual handling, COSHH substances, and the fact that the property is occupied during the works.
- Welfare arrangements — access to a toilet (the client’s, if they agree), hand washing facilities, and a place for workers to take breaks and eat (not in the room where you are using adhesives).
- Emergency procedures — what to do in case of a gas leak (move people away, avoid ignition sources and call 0800 111 999 from a safe place), an electrical incident (isolate supply, call 999), a fire, or an injury.
- Coordination — if you have an electrician and a gas engineer visiting on separate days, your CPP should describe how their work is sequenced and how information is shared between trades.
This can genuinely fit on a single A4 page. The point is not to create paperwork for the sake of it, but to show that you have thought about the risks before starting work. For more detail on what a CPP looks like, see our guide to construction phase plans.
What insurance do kitchen fitters need?
Some insurance is required by law in particular circumstances, while clients may require other cover by contract. The insurance you need for kitchen fitting depends on your business structure and the clients you work for.
Public liability insurance
Public liability insurance is generally voluntary, though clients often ask for it. It may cover eligible third-party injury or property-damage claims, subject to the policy terms and exclusions. Check the cover limit required by each contract.
Employers’ liability insurance
If you employ staff, including apprentices, employers’ liability insurance of at least £5 million is generally required under the 1969 Act. Exemptions can apply, including some unincorporated family businesses and companies whose only employee owns at least half the shares. Check whether your business qualifies.
Professional indemnity insurance
May cover eligible claims arising from advice or design, subject to policy terms. If you advise on worktop materials, layouts or appliances, check that those services are included. This is increasingly important if you offer kitchen design services as part of your fitting package.
Contract works (all-risks) insurance
May cover eligible damage to work in progress or materials, subject to policy terms. Check limits, excesses and exclusions for water damage and theft.
Keep copies of all insurance certificates in your project file. Many clients will ask to see them before you start work, and having them ready demonstrates professionalism.
What certificates and sign-offs should you collect?
At handover, give the homeowner the certificates and records that apply to the work, plus useful manuals and warranties. A buyer’s conveyancer or insurer may later ask for relevant records, but requirements depend on the job and circumstances.
- Appropriate Electrical Installation Certificate or Minor Works Certificate for electrical work, plus Building Regulations compliance evidence where notification is required.
- Gas work record or Building Regulations Compliance Certificate from the Gas Safe engineer, where applicable to the work.
- Building Regulations compliance or building-control completion evidence where applicable to structural, drainage or notifiable electrical work.
- Appliance manuals and warranty registrations for all fitted appliances.
- Worktop warranty documentation, including care instructions.
- Your own certificate of completion or handover document confirming the scope of work, the completion date, and your warranty terms.
- Copies of insurance certificates where held or required by the contract.
Before handover, assemble the certificates, warranties and relevant job records in one pack and give the homeowner a copy they can refer to later.
What does a complete kitchen fit paperwork checklist look like?
Here is the full list of paperwork you should have in place for a typical kitchen installation. Not every item will apply to every job, but this gives you the complete picture.
Before you start
Proportionate CPP and risk controls for the work; written RAMS where useful or required by the client; COSHH assessments for hazardous substances where exposure arises; applicable insurance details, Gas Safe registration for gas work, and your electrical self-certification or building-control arrangements.
During the work
Brief workers on the relevant risks and controls. Keep a briefing acknowledgement if useful or required by the contract, along with proportionate progress notes, changes to scope and photos of hidden work where helpful.
At handover
Electrical Installation Certificate or Minor Works Certificate, gas work record or Building Regulations compliance certificate where applicable, appliance manuals and warranties, and your completion and insurance records.
If this list looks daunting, remember that specialist certificates and manuals are often produced by your electrician, gas engineer or suppliers. Your job is to coordinate it, collect it, and hand it over. And if you want to automate the RAMS and COSHH assessments, that is exactly what The Site Book is built for.
Frequently asked questions
Do I need RAMS for a kitchen fit?
You must assess the risks of the work and control them. A client or principal contractor may ask for written RAMS as a contractual or site-entry requirement; CDM 2015 does not make a document called RAMS or worker signatures mandatory on every job. Even on domestic jobs, having RAMS demonstrates professionalism and protects you legally. A kitchen fit involves electrical work, potential gas work, COSHH-rated adhesives and sealants, manual handling of heavy worktops and appliances, and working with power tools in an occupied home. All of these carry significant risk. A concise RAMS covering the key hazards and your control measures takes very little time to produce and could save you a great deal of trouble if something goes wrong. Check the particular client's requirements before work starts.
Can I do kitchen electrics myself or do I need a Part P electrician?
It depends on the work and location. In England, Part P notification covers a new circuit, consumer-unit replacement, or an addition or alteration to an existing circuit in a specified special location such as the area around a bath or shower; a kitchen sink is not itself a special location. Wales also requires notification for some extensions to existing circuits in kitchens. A like-for-like socket replacement may be non-notifiable, but all electrical work must be safe and comply with the applicable standards. For notifiable work, use an electrician registered to self-certify or arrange building control before work starts. Keep the appropriate Electrical Installation Certificate or Minor Works Certificate and, where required, the separate Building Regulations compliance record.
Do I need a gas safe engineer for a kitchen fit?
Gas installation, reinstallation and pipework changes must be carried out by an engineer registered and qualified for that work. That includes moving a gas supply, capping a pipe, or installing a cooker, hob or boiler during a refit. HSE makes a narrow distinction for temporarily moving a freestanding cooker with a bayonet fitting to clean the space it normally occupies: that is not treated as gas work. It does not cover installing or reinstalling the appliance as part of a kitchen change. Ask the engineer what work record or Building Regulations compliance certificate applies, and keep any documents issued with the project file.
What insurance do I need for kitchen fitting?
Public liability insurance is generally voluntary but is often required by clients and is worth considering for third-party claims. A suitable policy may cover eligible third-party injury or property-damage claims, subject to its terms and exclusions. Check each client's contract for any required cover limit. If you employ staff, employers’ liability cover of at least £5 million is generally required, subject to exemptions such as some unincorporated family businesses and owner-only companies. You should also consider professional indemnity insurance, which may cover eligible claims arising from faulty design or advice — for example, if you recommended a worktop material that turned out to be unsuitable. Finally, contract works insurance (also called all-risks insurance) may cover eligible damage to work in progress, subject to policy terms — for example, if a flood damages the kitchen before it is handed over.
Do I need a construction phase plan for a kitchen fit?
In Great Britain, CDM 2015 requires a CPP for construction work, including a kitchen fit. Regulation 12(1) places the duty on the principal contractor where more than one contractor is involved; regulation 15(5) places it on the only contractor on a single-contractor job. There is no size exemption, but a small domestic plan can be proportionate. Under regulation 12(2), it should set out the health and safety arrangements, site rules and any applicable Schedule 3 measures. Regulation 15(6) applies those content requirements to the sole contractor. Northern Ireland has separate CDM 2016 rules.
What COSHH assessments do I need for kitchen fitting?
Assess substances where the work may expose people to a health risk, then identify suitable controls under COSHH. Common substances include silicone sealants (many contain fungicides and release acetic acid fumes during curing), tile adhesives and grouts (contain Portland cement, which is a skin sensitiser and respiratory irritant), PVA adhesives and contact adhesives for worktop edging, solvent-based cleaning products, two-part epoxy adhesives for stone or composite worktops, and dust from cutting worktops, tiles, or MDF. For each substance, your COSHH assessment should identify the hazards (from the safety data sheet), the people at risk, the control measures you will use (ventilation, PPE, skin protection), and the emergency procedures in case of exposure. In practice, most kitchen fitters use a small number of products regularly, so you can maintain a library of COSHH assessments and pull in the relevant ones for each job.

Kitchen-fit paperwork — the realistic minimum
Pros
- A kitchen fit needs a proportionate CPP; use risk assessments, method statements and COSHH controls where the work calls for them.
- Specialist electrical and gas trades provide the records required for their work; check what applies and collect them for handover.
- A proportionate paper trail protects you if the kitchen later leaks, fails, or injures someone during use.
- Having certs ready at handover reassures homeowners — a small compliance pack turns into a referral engine.
Cons
- Skipping the CPP because 'it's just a kitchen' breaches CDM 2015 — reg 15(5) where you are the only contractor, reg 12(1) where there is more than one contractor — and there is no size exemption.
- Missing required electrical or gas work records can leave a handover pack incomplete — check which certificates apply to the actual work.
- A generic 'kitchen fitter' RAMS template is not site-specific — the fragile worktop being lifted at 14 Acacia Avenue is different.
- Without a signed scope letter the homeowner may argue later that you agreed to work that was never in the quote.
