Why the License Number Is Important

Follow these steps to confirm that your engineer is registered and qualified:

Step 1: Visit the Official Gas Safe Register

Navigate to the UK’s official database at:
www.gassaferegister.co.uk

This is the only legitimate platform for checking certified gas professionals.

Step 2: Use the ‘Check an Engineer’ Tool

Select the “Check an Engineer” feature on the site. Then:

  • Enter the six-digit licence number

  • Alternatively, search by business name or postcode

Step 3: Review the Engineer’s Profile

The search results will display:

  • Full name of the engineer or plumber

  • Business or employer details

  • Registration status (active or expired)

  • Types of gas appliances they are qualified to work on (boilers, cookers, LPG)

  • Contact details, where available

What to Look For

  • The licence must be currently active

  • The engineer’s certifications must match the type of gas work you require

  • The name should align with their Gas Safe ID card and any official documentation you have received
