Gas engineering · free to start

Learn about gas engineering from the basics

Short lessons on what a gas engineer does, what to do if you smell gas, who the law lets do gas work in Great Britain and Northern Ireland, and how gas burns. Each sitting takes a few minutes on your phone.

Our free gas path teaches the knowledge side: safety, the law and how gas burns. It does not qualify you, assess you or put you on the Gas Safe Register.

Smell gas?

Everyone should know this, engineer or not.

No switches, flames or cigarettes. Open doors and windows if it is safe, get everyone out and call from outside: 0800 111 999 in Great Britain, 0800 002 001 in Northern Ireland, or the supplier’s emergency line for LPG. Call 999 if anyone is in danger.
