What you need to know
Gas cooker installation in SW18: what you need to know
Gas Safe requirement
Connecting any gas appliance to the mains supply is illegal for anyone who is not Gas Safe registered — it is a criminal offence under the Gas Safety (Installation and Use) Regulations 1998, not merely dangerous. This applies to freestanding cookers, built-in hobs, and range cookers. You can verify any engineer at GasSafeRegister.co.uk.
Freestanding gas cookers
A freestanding gas cooker connects to the gas supply via a wall-mounted bayonet point and a CE-marked flexible hose. The bayonet connector is a quick-release fitting — the flexible hose must be no longer than 2 metres and should be replaced at least every 5 years. Both the bayonet point and the flexible connector require an annual inspection.
Built-in gas hobs
A built-in gas hob requires a permanent hard pipe connection — a flexible hose and bayonet connector cannot be used. The engineer routes rigid copper pipework from the gas supply through or under kitchen units, which may require worktop cutouts or floor access. This work is more involved than a freestanding swap and takes 2 to 3 hours.
Flue and ventilation
Open-flued appliances require adequate room ventilation under Building Regulations Part J. Kitchen extraction fans can depressurise the room and affect combustion appliance performance. We check that extraction systems do not create a negative pressure environment and confirm ventilation requirements are met before commissioning.
What the job includes
We isolate the existing appliance safely, check the integrity of existing supply pipework, connect the new appliance, perform a full gas tightness test, functionally test all burners, and issue commissioning paperwork. No job is complete until a gas tightness test confirms zero pressure drop on the installation.
Landlord obligations
Gas cookers and hobs in rental properties must be included in the annual Gas Safety Check (CP12). A CP12 that does not cover all gas appliances — including the cooker — is not compliant and exposes landlords to criminal liability. We issue a fully compliant CP12 certificate covering every gas appliance on the property.
