When it comes to gas safety in UK properties, verification is everything. Whether you’re a landlord arranging a CP12 inspection or a tenant wanting to check your boiler installer, you must ensure your engineer is Gas Safe registered.
Fraser Bond explains how to search the Gas Safe Register online to confirm an engineer or business is legally certified—and protect your property from unsafe or illegal work.
The Gas Safe Register is the official list of engineers legally allowed to work on gas appliances in the UK. It replaced the CORGI system in 2009 and is the only recognised authority for gas engineer certification.
It exists to:
Protect homeowners, tenants, and landlords from unqualified installers
Provide a transparent, searchable database of registered professionals
Help enforce the Gas Safety (Installation and Use) Regulations 1998
Using an unregistered gas engineer can lead to:
Unsafe installations and gas leaks
Carbon monoxide poisoning
Fines, legal action, or invalid insurance for landlords
Verifying an engineer before work begins is not just good practice—it’s a legal safeguard.
Go to www.gassaferegister.co.uk – this is the only authorised site.
The site allows you to:
Check an engineer by licence number
Search for a business by name or postcode
Find a local registered engineer by work type and location
If you already have a CP12 or quote from an engineer, do the following:
Click “Check an Engineer”
Enter the 7-digit licence number on their Gas Safe ID card
Confirm:
The engineer is actively registered
They are certified for the type of work you need (e.g. boilers, pipework, cookers)
Their registration hasn’t expired
To verify a company (e.g. if you hired through an agency):
Click “Check a Business”
Enter the business name or postcode
View:
Business status and contact info
Engineers working under that business
Areas of certified gas work
Once verified, take a screenshot or save the page for your records—especially if you’re a landlord needing proof for compliance checks or property audits.
