Can I Install a Gas Cooker Myself?
You should not install a gas cooker or hob yourself. The law requires anyone doing gas work to be competent to do it, anyone doing it as part of their job to be on the Gas Safe Register, and landlords to use a registered engineer for any gas appliance in a let property. The Gas Safe Register's advice is to use a registered engineer for all gas work, including plugging in a freestanding cooker on a bayonet hose, and most cooker makers make that a condition of the warranty. The reason is not the connection itself but the checks that go with it: a gas tightness test, correct pressure, safe flames, working flame safety devices, a stability bracket and the right clearances.

What the law actually says. Gas work in homes is covered by the Gas Safety (Installation and Use) Regulations 1998. They say nobody may carry out work on a gas fitting unless they are competent, and that anyone doing gas work for payment, or as part of a business, must be a member of the Gas Safe Register. Connecting, disconnecting, moving or replacing a gas cooker or hob counts as gas work. If you are a landlord, the rules are stricter again: every gas appliance you provide has to be installed and maintained by a registered engineer and checked every year. In practice there is no sensible route for a householder to become competent at gas work without training, so the answer for almost everyone is a registered engineer.
Why a bayonet hose does not make it DIY. Many freestanding gas cookers connect through a flexible hose that clicks into a bayonet socket on the wall, which looks as simple as plugging in a kettle. The risks sit around it. The hose must be the right type and length, must not be kinked, stretched or resting on the hot back of the oven, and the socket must be in good order. The cooker must be fitted with a stability bracket or chain, so that it cannot tip forward if a child climbs on the open oven door or someone leans on it, pulling the hose out of the socket. The engineer then tests the whole installation for leaks, checks the working pressure at the cooker, and lights every burner, the oven and the grill to confirm they burn properly and that the flame failure devices shut the gas off when a flame goes out.
What a proper installation includes. A Gas Safe registered engineer connecting a cooker or hob will check the existing gas pipework is sound and correctly sized, carry out a tightness test on the installation, make the connection with the right fittings, fit a stability device on a freestanding cooker, and check the working pressure. They will check the flame picture on each burner, test the flame supervision on the hob and oven, and check the clearances the maker specifies to side walls, worktops, wall cupboards and any cooker hood above. They will also look at the ventilation in the kitchen against the maker's instructions and make sure the appliance is suitable for the gas supply, since a cooker set up for bottled LPG will not run safely on mains gas without conversion.
Built-in hobs and dual fuel range cookers. A built-in gas hob is usually connected with fixed pipework rather than a hose, and it is often part of a larger kitchen fit where the hob is cut into a new worktop. Range cookers are heavy, often dual fuel, and need both a gas connection and an electrical supply suited to their electric ovens. Large electric ovens and induction hobs often need their own dedicated circuit from the consumer unit, which is a job for an electrician rather than a gas engineer. If you are fitting a new kitchen, plan the gas point, the electrical supply and the cooker position together so neither trade has to undo the other's work.
Moving a cooker to a new position. Moving a gas cooker or hob means extending or rerouting the gas pipe, which is gas work from start to finish. In Chelsea's period houses the existing gas supply to a kitchen can be old steel or early copper pipe running under floors and behind panelling, and in mansion blocks it may come from a shared riser. An engineer will check the size and condition of the pipework before extending it, since a pipe that was fine for a small cooker may be too small once a bigger range cooker or a second appliance goes on the same run. Our guide to moving plumbing during a renovation covers the wider planning.
Switching from gas to induction. If you are replacing a gas cooker or hob with an electric or induction one, the gas supply to the old appliance must be disconnected and capped by a Gas Safe registered engineer. Pulling the hose out and leaving the bayonet socket, or cutting a pipe and pushing a cap on, is not safe. The engineer caps the pipe correctly, tests the installation for tightness afterwards and makes sure nothing else on the same run has been left without gas. If the cooker was the only gas appliance in the flat, speak to your gas supplier about the meter.
Mansion blocks and leases. Before buying a new gas cooker for a flat in a mansion block or converted house, check your lease and ask the managing agent. Some buildings restrict new gas appliances, some have rules about work on gas pipework in shared areas, and some require notice before any contractor works on the building's services. It is much easier to find out before the cooker arrives than after.
Signs an existing cooker was badly fitted. A faint gas smell near the back of the cooker, especially when you pull it out to clean, a hose that is kinked or trapped against the wall, a cooker that rocks or tips forward when you open the oven door, burners with lazy yellow flames, or soot on pans can all mean the cooker was not fitted or maintained properly. Turn the cooker off at its controls and have it checked. If you smell gas at any time, do not operate switches, open the windows, turn off the gas at the meter if you can safely reach it, leave the property and call the National Gas Emergency Service on 0800 111 999. Our guide on what to do if you smell gas explains each step, and our gas leak detection service covers the follow-up once the emergency line has made the property safe.
Why DIY gas work is a false saving. A cooker connection done badly can leak slowly for months before anyone notices, and a cooker burning poorly can produce carbon monoxide. Home insurance and cooker warranties can both be affected by unregistered gas work, and if you sell or let the property, a buyer's surveyor or a tenant's safety check may pick it up. Our guide to common DIY plumbing mistakes covers gas work alongside the water jobs that are safe to try yourself.
Getting it done properly in Chelsea. Emergency Plumber Chelsea sends Gas Safe registered engineers to connect and test gas cookers and hobs, cap off gas supplies when you switch to induction, and check an existing cooker that does not seem right. If you are a landlord, the cooker can be checked alongside the boiler on the same visit through our gas safety certificates service. Call 020 3002 6667 and tell us the make and model of the cooker, whether it is freestanding or built in, and whether the gas point is already in the right place. We cover Chelsea, Knightsbridge, Sloane Square, South Kensington and Fulham, and there is no call-out fee on jobs over 3 hours.
Quick tips
- Ask to see the engineer's Gas Safe ID card before any gas work starts, and check what type of work it covers.
- A freestanding cooker on a hose must have a stability bracket or chain fitted.
- Never leave a disconnected bayonet socket or cut pipe uncapped when switching to induction.
- Check your lease or ask the managing agent before fitting a new gas appliance in a block of flats.
- If you smell gas near the cooker, turn it off, open windows, leave and call 0800 111 999.
FAQs
Is it illegal to fit your own gas cooker?
The law requires anyone doing gas work to be competent, and anyone doing it for payment or as a business to be Gas Safe registered. Landlords must always use a registered engineer. The Gas Safe Register advises that all gas work, including connecting a cooker, is done by a registered engineer, and without training a householder is very unlikely to meet the competence requirement.
Can I connect a gas cooker with a bayonet fitting myself?
It is not recommended. The connection is quick, but a proper installation also includes a tightness test, a pressure check, burner and flame safety checks, the correct hose and a stability bracket. Most manufacturers require a Gas Safe engineer to fit the cooker for the warranty to apply.
Does a gas cooker need a stability chain?
A freestanding cooker connected with a flexible hose should have a stability bracket or chain fitted, so it cannot tip forward and pull the hose from the wall if weight is put on the open oven door. The engineer fitting the cooker should fit and check it.
Who can cap off the gas when I switch to an induction hob?
A Gas Safe registered engineer. They disconnect the old appliance, cap the supply correctly and test the installation for leaks afterwards. The new induction hob may also need its own circuit, which is a job for an electrician.
Does a gas cooker need a carbon monoxide alarm?
The rules that require landlords to fit carbon monoxide alarms exclude gas cookers, but a cooker can still produce carbon monoxide if it burns badly. An alarm in or near the kitchen, sited as the maker recommends, is a sensible precaution in any home with gas.
