How to Check if Your Gas Engineer Is Registered – UK Property Safety Guide

Why It’s Vital to Check Gas Engineer Registration

In the UK, only Gas Safe registered engineers are legally permitted to carry out gas work—including boiler installations, servicing, repairs, or issuing CP12 Gas Safety Certificates. If your engineer isn’t registered:

• Gas work may be illegal and unsafe

• Certificates (like CP12) will be invalid

• Insurance policies can be voided

• You may face prosecution as a landlord

Checking their registration protects you, your tenants, and your property.
