If you're a landlord, property owner, or even a tenant in the UK, knowing who’s qualified to carry out gas work is essential. Under UK law, only a Gas Safe registered engineer is legally permitted to work on gas appliances, boilers, or pipework.
Fraser Bond outlines the legal and safety reasons why it’s critical to ensure your engineer is properly registered.
A Gas Safe registered engineer is a professional who has passed industry-recognised assessments and is listed on the official Gas Safe Register—the UK’s legal authority on gas work qualifications. This register replaced CORGI in 2009 and is the only trusted source for confirming an engineer’s legitimacy.
Every registered engineer:
Has a unique 7-digit licence number
Must carry a Gas Safe ID card
Is qualified for specific types of gas work (e.g., boilers, fires, cookers)
Is subject to audits and compliance checks
According to the Gas Safety (Installation and Use) Regulations 1998, all gas work in rented or owned property must be completed by a Gas Safe registered engineer. This applies to:
Boiler installations and servicing
Gas appliance fitting
Pipework repairs or installation
Landlord safety checks (CP12 certificates)
Failing to comply can lead to prosecution, fines, or imprisonment.
If gas work is carried out by an unregistered person—even if done correctly—it can invalidate your property insurance. In the event of a fire, explosion, or carbon monoxide incident, your insurer may refuse to pay out.
Unqualified gas work puts lives at risk. Poor installations or undetected faults can lead to:
Gas leaks
Fires
Explosions
Carbon monoxide poisoning
Using a registered engineer helps prevent these dangers.
Ask to See Their Gas Safe ID Card
Confirm the photo, licence number, and expiry date. Check what types of gas work they’re certified for.

Use the “Check an Engineer” tool to verify their status by licence number or business name.
Keep Records
Save a copy of their ID or record their licence number for future reference—especially if you’re a landlord needing to provide evidence during inspections.
