Kitchen Renovations

Kitchen Renovations near you

A British kitchen refit usually happens inside a room that already exists: new units, worktops, appliances, flooring and lighting, often with the wall into the dining room taken out, or with the whole kitchen moved into a single-storey rear extension and the old kitchen turned into something else. Whether you are refreshing the doors and worktop or starting from bare brick, the shape of the job is set less by the design than by which parts of it are controlled work.

Most of a kitchen refit is uncontrolled. Fitting units, tiling, decorating and laying a floor need nobody's approval. Three things change that. Gas work is controlled by criminal law and can only be done by a registered business. Electrical work falls under Part P of the Building Regulations, and a kitchen refit almost always involves new circuits. And if you are creating a kitchen in a room that never had one, building control will want to see adequate ventilation and drainage, along with structural stability, electrical safety and fire safety.

Planning permission rarely bites on a kitchen inside the existing footprint. It bites on the extension you are wrapping around it, on flats and maisonettes, and on listed buildings, where consent is needed for internal work that affects the building's special interest.

Does a new kitchen need planning permission in the UK?

For a kitchen inside the existing house, almost never. The Planning Portal's position is that a planning application for installing a kitchen or bathroom is generally not required unless it forms part of a house extension. Replacing units, moving the sink, changing the layout and re-flooring are not development in the planning sense.

The exceptions are worth taking seriously, because two of them carry consequences well beyond a refused application. In a listed building you should consult the local planning authority before you start: listed building consent is required for work affecting the building's character as one of special architectural or historic interest, internal work included, and carrying it out without consent beforehand is a criminal offence. In a flat or maisonette, the householder permitted development rights that cover houses simply do not apply.

  • The kitchen is part of a new extension, in which case the extension itself is what needs assessing against permitted development limits or a planning application.
  • The property is listed, where consent is needed for internal alterations that affect its special interest, not only for what shows from the street.
  • The property is a flat or maisonette, which has no householder permitted development rights at all.
  • The work puts something new on the outside in a conservation area or other designated land, such as a flue or an extract terminal.
  • The project changes the use of the building, for example by creating a separate unit with its own kitchen.

Building control for a kitchen: refits, new kitchens and knocking through

The Planning Portal states that work to refit a kitchen with new units and fittings does not generally require building regulations approval, although the drainage or electrical work forming part of that refit may. The threshold moves when the kitchen goes somewhere it has never been: providing a kitchen in a room that did not have one is likely to need approval, so that the room has adequate ventilation and drainage and meets requirements for structural stability, electrical safety and fire safety.

Removing the wall between a kitchen and a dining room is a different matter again. That is structural work: the opening needs a beam sized by someone competent to size it, with bearings and support below, and it is building control work from the outset. The same applies to forming a wide opening into a new extension. Electrical work interacts with the structure here too — Approved Document P notes that Part A governs the depth of chases in walls and the size of holes and notches in floor joists, which is exactly where kitchen cabling and pipework tend to go.

You can use either your local authority's building control service or a private registered building control approver. Either way, ask your builder which route they are using and make sure the job ends with a completion certificate, because without approval you will not have the certificates of compliance you may need when selling.

Gas hobs and gas supplies: why this is Gas Safe territory, not a builder's

Gas is the part of a kitchen where the law is unambiguous. Regulation 3 of the Gas Safety (Installation and Use) Regulations 1998 provides that no person shall carry out any work in relation to a gas fitting unless competent to do so, and that an employer or self-employed person must be a member of a class of persons approved by the Health and Safety Executive — in practice, the Gas Safe Register. Disconnecting a hob to fit a worktop, moving the supply to a new island, capping off a redundant pipe or relocating the meter are all gas work.

Checking is quick and worth doing on the day. HSE points homeowners to the Gas Safe Register's check service, where the licence number from the engineer's ID card brings up their photograph and the details of their qualifications. The back of the card lists what the engineer is actually qualified to work on, so confirm the category covers the appliance in your kitchen rather than just that the card exists. Gas Safe Register is also one of the government-authorised competent person schemes, so a registered engineer can self-certify the building regulations side of the work.

Kitchen electrics and Part P: what is notifiable and who can certify it

Approved Document P covers electrical safety in dwellings in England, and it defines a short list of notifiable work: installing a new circuit, replacing a consumer unit or fuse box, and altering existing circuits in a special location. In England, special locations are the spaces around baths and showers, so a kitchen is not itself a special location and adding a socket to an existing kitchen circuit is generally not notifiable.

A real kitchen refit is a different story, because it usually brings new circuits with it — a dedicated supply for an electric oven or induction hob, new ring or radial circuits for worktop sockets, a rewire back to a consumer unit that then needs replacing. All of that is notifiable, and it must be certified. The straightforward route is an electrician registered with a competent person scheme such as NICEIC or NAPIT, who can self-certify compliance instead of you applying to building control.

  • A completely new circuit for an oven, hob or utility appliance is notifiable work wherever it runs in the house.
  • Replacing the consumer unit, which older kitchens often force because there are no spare ways, is notifiable in its own right.
  • Alterations to existing circuits are notifiable only in special locations, which in England means the spaces around baths and showers rather than kitchens.
  • Approved Document P expects installations to be designed and installed in accordance with BS 7671, the national wiring standard.
  • Ask for the electrical installation certificate describing the work carried out, which Approved Document P treats as part of the information a householder should be given.
  • If your electrician is not scheme-registered, the work has to be notified to a building control body or certified by a registered third party instead.

Extract ventilation over the hob: what Approved Document F expects

The Planning Portal's guidance is that any new kitchen, bathroom or shower room, utility room or toilet should be provided with a means of extract ventilation to reduce condensation and remove smells, with the detail set out in Approved Document F. Where a kitchen is being refurbished rather than created, the requirement is to ensure that existing extract ventilation is retained or replaced, so taking out a working extractor and not putting one back is a step in the wrong direction.

This matters more in British housing than the paperwork suggests. Cooking is one of the largest sources of moisture in a home, and in a solid-walled Victorian or Edwardian house with cold external walls, that moisture finds the coldest surface and condenses there. A recirculating hood with a charcoal filter deals with smells but returns the water vapour to the room; ducting to the outside is what actually removes it. If the layout is being redrawn anyway, that is the moment to plan a duct run rather than to discover later that there is nowhere for one to go.

What drives the cost of a kitchen renovation in a British home

Describing a kitchen as a single figure is meaningless, because two kitchens of identical size can differ by a multiple depending on how much of the building has to change around them. The variables below are the ones that move a British quotation most, and they are worth settling before you compare tenders, so that everyone is pricing the same job.

When you are ready to gather quotations, LokalMatch lets you set out the kitchen once — the room, whether the layout or the services are moving, your postcode and your timing — and matched kitchen fitters and builders contact you themselves; the professionals pay for the requests they receive. LokalMatch does not do the work, does not set or influence prices, and does not vet, rank or recommend the businesses that respond, so comparing their registrations, insurance and written scope is still your job.

  • Whether the services move: relocating the sink, the soil connection or the gas supply costs more than reusing the existing positions, because it draws in controlled trades and floor work.
  • Whether a wall comes out: a structural opening needs a designed beam, support below it and building control involvement, which is a project in itself.
  • Worktop material and how it is templated and fitted, since stone and composite worktops are measured and cut after the units are in.
  • Appliance specification, and particularly whether you are moving from gas to induction, which usually means a new circuit rather than a like-for-like swap.
  • The condition of what is behind the old units in an older house, including uneven walls, failed plaster, redundant pipework and floors that need levelling.
  • Access in a flat or a terrace with no off-street parking, where everything is carried in by hand and waste is carried back out the same way.
  • Whether the kitchen forms part of an extension, which brings planning or permitted development checks, building control, and often a party wall notice.

Guarantees on a kitchen: workmanship, products and your statutory rights

There are three separate layers of protection on a kitchen and they are easy to muddle. The first is your statutory rights: under the Consumer Rights Act 2015 the fitting must be carried out with reasonable care and skill, and if it is not, you can require repeat performance at the trader's cost or a reduction in price. Those rights cannot be excluded by anything in the contract.

The second is the trader's own guarantee. TrustMark registered businesses are expected to provide a minimum two-year guarantee, backed by insurance that covers workmanship, the rectification of defects and non-compliance with the Building Regulations if the business stops trading — which is the scenario an ordinary written guarantee does nothing about. Where a complaint cannot be settled with the business or its scheme provider, TrustMark members are subject to the Dispute Resolution Ombudsman.

The third is product warranty: units, worktops and appliances carry manufacturer guarantees with their own conditions, often including how they were installed. Keep the paperwork together with the electrical installation certificate and the Gas Safe record, because those are the documents that show the controlled work was done properly.

Kitchen Renovations: frequently asked questions

Do I need planning permission to replace my kitchen?

Generally not. The Planning Portal's guidance is that a planning application for installing a kitchen is not usually required unless the work forms part of a house extension. The exceptions are listed buildings, where you should consult the local planning authority and where consent covers internal work affecting the building's special interest, and flats and maisonettes, which have no householder permitted development rights and so need an application for work that a house could do freely.

Does a kitchen refit need building regulations approval?

Refitting an existing kitchen with new units and fittings does not generally require approval, but the drainage and electrical work within that refit may, and new circuits almost always do. Creating a kitchen in a room that never had one is likely to need approval so the room has adequate ventilation and drainage and meets requirements for structural stability, electrical safety and fire safety. Removing a wall is structural work and needs building control regardless.

Who is allowed to connect a gas hob?

Only someone working for a Gas Safe registered business. Regulation 3 of the Gas Safety (Installation and Use) Regulations 1998 requires anyone carrying out work on a gas fitting to be competent, and requires the employer or self-employed person to belong to a class of persons approved by HSE. Ask for the engineer's ID card, check the licence number on the Gas Safe Register, and confirm from the back of the card that they are qualified for that type of appliance.

Does my electrician have to be registered with a scheme?

Not legally, but it is much simpler if they are. Notifiable work — a new circuit, a replacement consumer unit, or altering circuits in a special location — has to be certified. An electrician registered with a government-authorised competent person scheme such as NICEIC or NAPIT can self-certify compliance with the Building Regulations. An unregistered electrician's work must instead be notified to a building control body or certified by a registered third party, which takes longer and costs more.

Does a cooker hood have to vent outside?

New kitchens are expected to have a means of extract ventilation to reduce condensation and remove smells, with the detail in Approved Document F, and on a refurbishment any existing extract ventilation should be retained or replaced. A recirculating hood filters odours but puts the moisture back into the room, so in a house with cold solid walls a ducted extract is the option that actually reduces condensation. Plan the duct route while the layout is still on paper.

Is the guidance the same across the UK?

No. Approved Document P and the English Approved Documents apply in England, and Scotland and Northern Ireland run separate systems entirely. In Scotland you may need a building warrant from the council before work starts, and it is an offence to begin work requiring one without it. Northern Ireland works to the Building Regulations (Northern Ireland) 2012, administered by district councils' building control. Gas Safe registration, by contrast, is a UK-wide legal requirement.

What affects the cost of kitchen renovation

Prices depend on the details of your project. We only publish price ranges when they’re backed by real LokalMatch quote data or reliable sources. Until then, here’s what usually changes the price:

  • Size of the kitchen and whether the layout changes
  • Cabinets: stock, semi-custom or custom
  • Countertop material
  • Moving plumbing, gas or electrical
  • Appliances and ventilation
  • Flooring, backsplash and lighting
  • Wall removal or other structural work

How to compare kitchen renovation contractors before you hire

  • Look for a contractor or designer who has finished kitchens similar to what you have in mind, and ask to see photos and a few in person if possible.
  • Settle the layout and the cabinet, counter and appliance choices before you compare final quotes.
  • Ask who coordinates the cabinet maker, countertop installer, plumber and electrician.
  • Get a written contract with the scope, the timeline and a payment schedule tied to stages of work.
  • Ask how long you'll be without a working kitchen and plan for it.

Questions to ask kitchen renovation contractors before you hire

  • Is this quote for a full remodel or a refresh, and what exactly is included?
  • Who orders the cabinets, counters and appliances, and what happens if they arrive late?
  • Will plumbing, gas or electrical lines need to move, and who will do that work?
  • Does this project need a permit, and will you get it?
  • How long will the kitchen be out of use?
  • What warranty do you offer on your work, and what do the product warranties cover?

Kitchen renovation permits and local rules

Some kitchen renovation work needs a permit or has to meet local bylaws. Rules vary by municipality, so ask your pro whether a permit is needed and who will apply for it — and check with your city or town if you’re unsure.
