What you do
Gas engineers install and maintain domestic and commercial gas appliances including boilers, cookers, and fire heaters. You commission new-build central heating systems, service boilers annually, diagnose faults, carry out safety checks on properties, and respond to gas emergencies. All gas work must be carried out by Gas Safe Registered engineers. Many gas engineers also hold qualifications in oil heating and heat pump installation, giving access to the rapidly growing renewable heating market.
Why this career is resilient
Gas Safe registration is a legal requirement for all gas work in the UK — it is not possible to cut costs by using unqualified labour. The 17 million gas-heated homes in the UK require annual servicing. The UK government's decarbonisation programme will require retrofitting millions of homes with heat pump and hybrid systems over the next 15 years — creating new demand for heating engineers with renewable energy skills rather than eliminating existing work.
