In the UK, to fully qualify as a gas service technician you’ll need:

To get Gas Safe registration, you’ll need a qualification that covers the safety requirements for the type of appliances you want to work on, for example boilers. If your qualification doesn’t cover all the safety requirements, then you could get your skills and knowledge assessed through the Accredited Certification Scheme (ACS).

You could also get into this career through an apprenticeship.

The job can be physically demanding and may involve working in small, cramped spaces or at height.

Career Path & Progression:

With experience, you could move into gas engineering, or supervisory and management roles.

You could also set up your own gas fitting business, but you’d need considerable experience to do this.
