How to Check if a Tradesperson is Gas Safe Registered
Gas Safe registration is a legal requirement for anyone working on gas appliances in the UK. Here's how to verify it — and why it matters.
If you're having any work done on a gas boiler, cooker, fire or pipework, the person doing it must be Gas Safe registered. This isn't a recommendation — it's a legal requirement. Hiring an unregistered engineer puts your family at risk and could invalidate your home insurance.
What is Gas Safe registration?
Gas Safe Register is the official list of gas engineers who are legally allowed to work on gas appliances in the UK. It replaced CORGI registration in 2009. Every registered engineer carries a Gas Safe ID card showing their licence number, the types of gas work they're qualified to carry out, and the expiry date of their registration.
How to check registration
You can check any engineer's registration on the Gas Safe Register website at gassaferegister.co.uk. Enter the engineer's licence number or their business name. The register will confirm whether they're currently registered and what types of gas work they're qualified to do.
Always ask to see the engineer's Gas Safe ID card in person before work starts. The card has a hologram and a QR code you can scan to verify it's genuine. Check both sides — the front shows personal details, the back lists the specific appliances and work types they're qualified for.
Why the type of work matters
Registration isn't a blanket qualification. An engineer registered to work on domestic boilers may not be qualified to work on LPG appliances or commercial equipment. Always check that the engineer's qualifications cover the specific work you need done.
What about boiler servicing?
Annual boiler servicing must also be carried out by a Gas Safe registered engineer. It's not just a good idea — many boiler warranties require it. A service typically takes around an hour and should include a visual inspection, a flue gas analysis, and a check of all safety controls.
Red flags to watch for
- Engineer can't produce a Gas Safe ID card
- Card is expired or the licence number doesn't match the register
- Engineer says Gas Safe registration 'isn't necessary' for the job
- Quote is significantly cheaper than others — unregistered engineers often undercut on price
- No written quote or invoice provided
