Check the Register


Gas Safe Register is the official list of businesses that are legally permitted to carry out gas work. Every registered business employs an engineer(s), who is issued with a Gas Safe ID card. Not all engineers are qualified to do all types of gas work – so remember to check their ID card before any work is carried out.

If you need gas work done in your home or workplace, you can use the different search options below to find a registered business or check an engineer is registered and qualified for the work you need doing.

Check an Engineer

As a result of recent COVID-19 restrictions affecting the ability of registered engineers to renew their gas safety qualifications, registrations have been temporarily extended.

Therefore, if your engineer’s ID card shows a job category which has expired on or from the 1 March 2020 and this type of work is due to be carried out at your property, please check the engineer’s current registration status. You can do this by using our on-line Find and Check services.

To check if an individual engineer is currently Gas Safe registered you will need to know their unique 7-digit licence number. You will find this on the engineer's Gas Safe ID card.

Please note that we issue engineers with a new ID card annually, and each new card will have a different licence number.

The licence number is a 7 digit number on the engineer's ID card.

All Gas Safe registered engineers carry a Gas Safe ID card with a unique licence number. Always ask to see their card.


Check they're qualified to do the work

Gas engineers will often have a range of qualifications that allow them to carry out specific types of gas work. It's important to check what work they are qualified to do before you use them.
