What the job is

Gas work is the most tightly regulated of the building services trades: you cannot legally work on gas appliances unless you are Gas Safe registered, and registration depends on holding current assessed qualifications.

That legal gate is why gas engineers earn well. Most come through a plumbing or gas engineering apprenticeship, then keep their ACS assessments renewed every five years. Service and breakdown work is year-round with a winter peak, and many engineers work on manufacturer or social housing contracts with company vans and steady hours.

A typical day

  • Install, commission and service gas boilers and appliances
  • Test for tightness, check pressures and analyse flue gases
  • Diagnose and repair breakdowns on heating systems
  • Carry out landlord gas safety checks and issue certificates
  • Advise customers honestly about repair versus replacement
