What is the Gas Safe Register?

The Gas Safe Register is a campaigning body that promotes gas safety standards in the UK. The register itself is the official list of gas engineers who are registered to work safely and legally on boilers, cookers, fires and all other gas appliances. The Gas Safe Register was created in 2009, previously it was known as CORGI. By law, all gas engineers must be on the Gas Safe Register. 

What does the Gas Safe Register do?

The Gas Safe Register seeks to improve safety-standards around the installation and maintenance of gas appliances. It carries out regular inspections of Gas Safe registered engineers to ensure all the engineers are suitably qualified to work with gas. It has a national investigations team, which tracks down illegal gas workers. It investigates reports of unsafe gas work and educates consumers about gas safety.

Which gas jobs must be done by a registered engineer?

All gas work carried out in your home should be done by a Gas Safe Register-accredited engineer. Gas work includes:

  • installing, repairing or servicing a gas boiler
  • installing or repairing a gas fire, gas cooker or hob.

Not all gas engineers are qualified to do all types of gas work. Every Gas Safe registered engineer should carry a Gas Safe ID card, featuring the Gas Safe triangle. The engineer's qualifications will be listed on the back of the card - always check what type of work your gas engineer is qualified to undertake.

How to find a registered engineer

The Gas Safe Register website lists local registered businesses and traders. You can search for a registered engineer using your address or the name of the trader or business, if known. The website shows you the names of any engineers working for registered businesses and specifically which gas appliances individuals are qualified to work on. You can also contact Gas Safe Register on 0800 408 5500 to check local traders and businesses.

Alternatively, you can find a Which? endorsed gas engineer on Which? Trusted Traders. All our endorsed traders that work with gas are listed on the Gas Safe Register - we check their listing as part of our assessment process.

Always check the engineer's Gas Safe ID card

Before you let a gas engineer into your home, make sure you check the front and the back their Gas Safe ID card. If they don’t show this to you when they turn up at your door then don’t be afraid to ask to see it.

Details to check on the front of the card: 

  • the engineer's photo
  • the start and expiry dates
  • the licence number
  • the security hologram
  • the engineer is from the business you employed

Details to check on the back of the card:

  • the engineer is qualified to carry out the gas job you need them to do
  • their qualifications are up to date
