Gas Safe is the only badge that matters on the doorstep.
Every gas appliance in your home — boiler, cooker, fire, flue — must legally be worked on by a Gas Safe registered engineer. Here's what that means, why it protects your family, and how to check the engineer at your door.
Not sure what's wrong? Ask Dale to help work out the fault before you book.
Gas is invisible. The consequences of getting it wrong aren't.
A badly fitted boiler can leak gas, spill carbon monoxide into the room, or fail catastrophically under pressure. You can't smell CO. You can't see a hairline flue crack. And you almost never get a second warning.
The Gas Safe Register exists so every homeowner in the UK can, in under thirty seconds, verify that the person about to touch their gas is trained, tested and legally allowed to do it.
"No person shall carry out any work in relation to a gas fitting… unless he is competent to do so and is a member of a class of persons approved for the time being by the Health and Safety Executive."

A short, clear guide to understanding the Gas Safe Register, spotting an illegal gas worker, and keeping your home and family safe.

Every year in the UK, illegal gas work still kills.
These aren't abstract numbers — they're the reason the register exists, and the reason we never let anyone unregistered near a customer's home.
Four quick checks before any gas engineer starts work
Takes less than a minute. Saves you from the one job you never want to have to fix.
- 1Ask for the ID card
Every Gas Safe engineer carries a photo ID card with a licence number, start & expiry date and appliance categories they're qualified on.
- 2Check the licence number
Search the seven-digit number on gassaferegister.co.uk — it confirms the engineer, their business and what gas work they can do.
- 3Confirm the categories
Boilers, cookers, gas fires and commercial gas are separate qualifications. Match the card to the job before work starts.
- 4Keep the paperwork
A Benchmark logbook entry, service record or CP12 is your proof the work was done to Gas Safe standards. Store it with your deeds.
What being on the register actually means
Not just a logo on a van — an ongoing, enforced standard your family can rely on.
Only Gas Safe engineers may work on your gas appliances. Anyone else is breaking UK law and putting your home at risk.
Every registered engineer is trained, examined and re-inspected. It's not a one-off badge — it's continuous competence.
Correct installation and annual servicing catch carbon monoxide, flue spillage and gas leaks before they hurt anyone.
Boiler manufacturers and home insurers require a Gas Safe engineer. Skip it and you void both — the day you need them most.

If you've ever had a job done by someone who told you "the paperwork's not really necessary" — please, get a Gas Safe engineer to check it. It could be the most important call you ever make.
Frequently asked questions
What is the Gas Safe Register?
It's the official UK gas registration body — the legal replacement for CORGI since 2009. Only engineers listed on the Gas Safe Register are legally allowed to work on gas appliances, boilers, cookers or flues in your home.
How do I check my engineer is Gas Safe registered?
Ask for their Gas Safe ID card and check the seven-digit licence number on the back of the card against the register at gassaferegister.co.uk. Our number is 204352 — you can look us up in seconds.
Is it illegal to use an unregistered engineer?
Yes. Under the Gas Safety (Installation and Use) Regulations 1998 it is a criminal offence for anyone not on the Gas Safe Register to carry out gas work. Using one also invalidates your boiler warranty and your home insurance.
What are the risks of a badly installed gas appliance?
Carbon monoxide poisoning, gas leaks, fires and explosions. Every year around 30 people die and hundreds more are hospitalised in the UK from unsafe gas work. The vast majority is preventable.
How often should my boiler be serviced?
Annually. A Gas Safe engineer will strip, clean and pressure-test the boiler, check the flue for spillage and issue a service report. It's a legal requirement in rented homes and a manufacturer-warranty requirement in most owned ones.
What is a Gas Safety Certificate (CP12)?
A landlord safety certificate — an annual inspection of every gas appliance in a rented property, carried out and signed off by a Gas Safe engineer. We issue CP12s across Brighton & Hove for both landlords and letting agents.
