What's it all about?

Your day-to-day duties might include:

  • installing appliances and systems
  • carrying out planned maintenance checks on systems and equipment
  • testing controls and safety devices to make sure they’re working properly
  • finding and repairing gas leaks using computerised fault-finding equipment
  • replacing or repairing faulty or old parts
  • ordering new parts
  • keeping records of work you’ve carried out
  • giving customers advice about gas safety and energy efficiency

You’ll also give customers quotes for jobs, sell additional company services and deal with complaints.

To fully qualify as a gas service technician you’ll need:

  • a recognised gas industry Level 3 qualification
  • Gas Safe registration (used to be called CORGI registration)

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.
