Check if a gas engineer is Gas Safe registered before allowing them to work on your boiler, cooker, gas fire or pipework. This is one of the most important safety checks a homeowner, landlord or tenant can make in the UK.
Gas work should be carried out by appropriately qualified, Gas Safe registered engineers.
This helps protect people from unsafe work on boilers, cookers, gas fires, meters and pipework.
Unsafe gas work can lead to serious safety risks, including fire, explosion or carbon monoxide danger.
Checking registration is therefore a basic but essential step before work begins.
A genuine Gas Safe registered engineer carries an ID card.
Before work starts, ask to see it.
Do not feel awkward about doing so.
A legitimate professional should expect this question.
You are checking both identity and qualification.
Do not just glance at the card.
Take a proper look.
Check:
This last point is especially important.
An engineer may be registered, but not qualified for every type of appliance or category of gas work.
You can use the official Gas Safe Register website to check whether an engineer or business is currently registered.
Depending on what details you have, you may be able to check using:
This is a useful second step in addition to checking the physical ID card.
The back of the ID card shows what kind of gas work the engineer is qualified to carry out.
That matters because different categories can apply to different appliances or types of work.
For example, checking a domestic gas boiler is not the same as working on every possible gas installation.
Before letting work begin, make sure the engineer is qualified for the appliance or job in question.
Many people stop at “yes, the person is registered”.
That is only part of the check.
You should also confirm that:
This is especially important if the job involves a boiler, flue, meter position, pipework alteration or another more specific gas-related task.
Be cautious if:
These signs do not automatically prove wrongdoing, but they are reasons to pause and verify.
Do not allow gas work to proceed if you are not satisfied that the engineer is properly registered and qualified for the job.
It is far better to delay an appointment than allow unsafe or unverified gas work in your home.
If an appliance is suspected to be unsafe, do not continue using it until it has been checked appropriately.
Landlords should use Gas Safe registered engineers for maintenance and annual gas safety checks on gas equipment they provide for tenants.
If you are arranging a landlord gas safety visit, you should still verify that the engineer is correctly registered and competent for the work.

Ask to see the engineer’s ID card and verify the registration details through the official Gas Safe Register.
No. You should also check the expiry date and the qualifications on the back.
Not necessarily. Registration does not automatically mean the engineer is qualified for every type of gas work. Always check the relevant appliance categories.
Yes. Where relevant, checking the business details can be useful alongside the individual engineer check.
Do not proceed until you are satisfied that the engineer is correctly registered and qualified for the job.
