In Great Britain, anyone who works on gas appliances, fittings or pipework for payment must be on the Gas Safe Register. That includes boilers, cookers, hobs, gas fires and the pipework connecting them.
Why it matters
Badly fitted or poorly maintained gas appliances can leak gas or produce carbon monoxide — a gas you can't see, taste or smell. Registered engineers are trained and assessed on the specific appliances they work on, and their work can be inspected.
How to check an engineer
- Ask to see their Gas Safe ID card. It has a photo, licence number and expiry date.
- Check the back of the card: it lists the type of gas work they're qualified to do (for example, domestic boilers or cookers).
- Verify the number on the Gas Safe Register website or by calling the register.
Signs of an unsafe appliance
- A lazy yellow or orange flame instead of a crisp blue one
- Black marks or soot around the appliance
- Excess condensation in the room
- A pilot light that keeps going out
- Headaches, dizziness or nausea that ease when you leave the house
Fit an audible carbon monoxide alarm in every room with a gas appliance — they're inexpensive and could save a life.
Landlords
If you rent out property, you're legally required to have a gas safety check every 12 months and keep the record.
All LPS gas work is carried out by Gas Safe registered engineers who will happily show you their card. Book a boiler service or get in touch.
