When it comes to gas appliances in your home—such as boilers, cookers, and fires—safety should always be your number one priority.
n the UK, that responsibility is overseen by the Gas Safe Register, the official list of engineers legally allowed to work on gas systems.
Whether you’re a homeowner, landlord, or tenant, understanding what the Gas Safe Register is and why it matters can help you avoid dangerous mistakes and ensure your property is in safe hands.
What Is the Gas Safe Register?
The Gas Safe Register is the UK’s official gas registration body, appointed by the Health and Safety Executive (HSE).
It replaced CORGI registration in 2009 and now acts as the single authority for all gas engineers across England, Scotland, Wales, Northern Ireland, and the Isle of Man.
Any engineer who wants to carry out gas work—whether it’s installing a boiler, servicing a gas fire, or fixing a gas leak—must be listed on the Gas Safe Register by law.
You can check whether a business or individual is registered by visiting the official Gas Safe Register website, where you can search by company name, engineer number, or postcode.
Why Is the Gas Safe Register So Important?
1. It Protects You from Unsafe Work
Gas work that isn’t completed properly can lead to serious risks, including:
- Gas leaks
- Explosions
- Carbon monoxide poisoning
Only registered engineers have the necessary qualifications and are regularly inspected to ensure their work meets industry standards. Hiring someone not on the Gas Safe Register puts your household and property in danger.
2. It’s a Legal Requirement
In the UK, it is illegal for any person or company to carry out gas work without being on the Gas Safe Register. This applies to all types of gas appliances and pipework in both domestic and commercial properties.
Landlords, in particular, are legally required to use Gas Safe registered engineers when conducting annual gas safety checks and issuing Gas Safety Certificates (CP12).
3. You Can Verify Engineers Easily
One of the best features of the Gas Safe Register is the ability to verify an engineer’s credentials quickly and easily. Every registered gas engineer carries a Gas Safe ID card, which shows:
- Their license number
- The appliances they’re qualified to work on
- The expiry date of their registration
Don’t be afraid to ask to see their card before any work begins—any reputable engineer will be happy to show it.
What Work Must Be Done by a Gas Safe Registered Engineer?
You should always use a registered engineer for the following:
- Boiler installation, servicing, and repair
- Fitting or fixing gas fires or cookers
- Installing or maintaining gas pipework
- Gas safety inspections for landlords or new home buyers
- Diagnosing carbon monoxide alarms or leaks
Trying to save money by hiring an unregistered engineer may not only void your home insurance—it could put lives at risk.
How to Check if an Engineer Is on the Gas Safe Register
It’s easy to check if an engineer or business is registered:
- Visit gassaferegister.co.uk
- Click on “Check an Engineer”
- Enter their name, ID card number, or business name
- Review their qualifications and areas of work
This quick step can save you a lot of trouble and give you peace of mind that your property is in capable hands.
What Should You Do if You Suspect Illegal Gas Work?
If you believe someone is working with gas appliances without being on the Gas Safe Register, you should report it immediately. The Gas Safe Register investigates illegal gas work and takes appropriate enforcement action when needed.
Reports can be made directly through the Gas Safe website or by calling their helpline.
