Why This Matters

It is illegal for any engineer to carry out gas work unless they are registered with the Gas Safe Register — the official body appointed by the Health and Safety Executive. Unregistered gas work is dangerous, invalidates your home insurance, and is a criminal offence for the person carrying it out. Each year, dozens of people in the UK die from carbon monoxide poisoning linked to poorly fitted gas appliances.

How to Check the Gas Safe Register

Online: Visit gassaferegister.co.uk and search by the engineer's name, company name, or licence number. The search is free and instant.

By phone: Call Gas Safe Register on 0800 408 5500.

Check the ID card: Every Gas Safe registered engineer carries a photo ID card. The back of the card lists the appliances they're registered to work on. Ask to see it before any work begins.

What to Look for on the ID Card

  • A unique licence number
  • The Gas Safe Register logo
  • An expiry date (cards must be renewed annually)
  • A list of "appliance categories" — this shows which gas work the engineer is qualified to carry out
