Short answer: no — not unless you are Gas Safe registered. In the UK it is illegal for anyone who is not on the Gas Safe Register to connect a gas cooker or carry out gas work. You can plug in an electric cooker, but the moment a gas connection is involved, the law requires a Gas Safe registered engineer. Here is what that means, what you can do yourself, and what a proper installation looks like.
Is it legal to install my own gas cooker?
Under the Gas Safety (Installation and Use) Regulations 1998, gas work must be carried out by a competent person who is Gas Safe registered. Fitting, connecting or disconnecting a gas cooker counts as gas work. If you are not registered, doing it yourself is a criminal offence, and the Health and Safety Executive can pursue substantial fines or even a custodial sentence for dangerous, unregistered gas work.
It is a common myth that “it is your own home, so you can do what you like.” You cannot. The law applies regardless of who owns the property, because a badly connected cooker does not only put you at risk — it puts neighbours and future occupants at risk too.
What can I legally do myself?
Very little, and that is deliberate. You are allowed to operate or replace parts designed for the user — for example, a control knob that has pulled off. What you must not touch is anything that disturbs the gas-carrying components: the supply pipe, the bayonet connection, the flexible hose, or anything that affects how the gas burns. If a job involves the gas supply in any way, it is an engineer’s job.
What does a proper gas cooker installation involve?
When we fit a gas cooker in a kitchen across East London, a standard installation runs roughly like this:
- Check the existing supply. We inspect the gas point, isolation tap and pipework before anything is connected.
- Connect with the correct components. A freestanding cooker is connected with an approved bayonet fitting and a flexible hose of the right length and rating — not stretched, kinked, or resting against the hot oven.
- Secure it. Freestanding cookers should have a stability bracket or chain so the appliance cannot tip forward when a child or a pan pulls on an open oven door.
- Tightness test. We carry out a gas tightness test to confirm there are no leaks.
- Check it burns correctly. Every burner is lit and checked. The flame should be crisp and blue; a lazy yellow or orange flame is a warning sign. On ovens we confirm the flame supervision device works.
That stability bracket and the flame-supervision check are the two steps DIY installs almost always skip — and they are exactly the things that turn a cheap “saving” into a dangerous appliance.
Signs of a badly installed gas cooker
If a previous cooker was fitted by someone unregistered, watch for a smell of gas, yellow or orange flames instead of blue, black or sooty marks around the appliance, a flexible hose touching the oven or stretched tight, or no stability bracket on a freestanding cooker. A yellow flame can mean incomplete combustion, which produces carbon monoxide — a gas you cannot see or smell. If you ever suspect a leak, turn off the supply at the meter, open windows, avoid switches and naked flames, and call 0800 111 999. We can then locate and repair the cause — see our gas leak detection page.

Frequently asked questions
Is it illegal to fit my own gas cooker?
Yes. Only a Gas Safe registered engineer may connect a gas cooker. A homeowner doing their own gas work is breaking the law and can face prosecution.
Can I plug in a gas cooker myself?
A gas cooker is not simply plugged in — it must be connected to the gas supply with the correct fitting and tightness-tested by a Gas Safe registered engineer.
Do you confirm the cooker is safe?
Yes. After installation we confirm the appliance is safe and working. We can also check your other gas appliances at the same time, useful for landlords needing a CP12 certificate.
