Gas safety is not just about completing a check—it’s about ensuring that your certificate remains valid and compliant. Whether you're a landlord responsible for a rental property or a tenant concerned about safety, knowing how to confirm the legality of your CP12 gas safety certificate is essential.
Fraser Bond explains how to check if your CP12 is still legal, helping you avoid costly fines and unsafe living conditions.
A CP12, or Gas Safety Certificate, is a legally required document for rented properties in the UK. It confirms that a Gas Safe registered engineer has inspected all gas appliances and systems and deemed them safe for use.
The certificate must be renewed every 12 months, and a copy must be provided:
To new tenants before they move in
To existing tenants within 28 days of inspection
Locate your current certificate—either in print or digital format—and look for:
Date of inspection
Next inspection due date
If more than 12 months have passed since the date shown, the certificate is no longer valid, and a new inspection is required immediately.
Visit www.gassaferegister.co.uk and:
Use the “Check an Engineer” tool
Enter the 7-digit licence number from your CP12
Confirm the engineer is still actively registered and certified for the gas work listed
If the engineer’s registration has lapsed, the certificate may be invalid—even if it’s within the 12-month window.
A valid CP12 should include:
Engineer name and business details
Gas Safe registration number
List of all tested appliances (boiler, hob, oven, etc.)
Results of all safety checks
Clear indication that all tests were passed
Missing or incorrect details may void the certificate.
If your certificate has expired or was never valid:
Landlords can face fines, enforcement action, and invalidated insurance
Tenants may be living in unsafe conditions, and should report concerns to the landlord or local authority
Buyers should delay contracts until a new inspection confirms legal compliance
