Work Activities

As a Gas Service Engineer, you will fit gas appliances and piping in homes and businesses.

You will firstly pick up your daily appointment list - often by email or telephone. Then you'll collect any spare parts and materials you'll need either from the local heating merchant, or have the spares delivered to specified pick-up points. You may use a laptop or tablet to keep in touch with a service centre and order spare parts.

Many Gas Service Engineers do routine service visits for customers who have a service contract with the company.

Once you reach a customer's premises, you'll:

  • test appliances thoroughly, paying strict attention to safety procedures.
  • use your fault finding skills to spot problems
  • answer customer questions and show them how best to use appliances
  • advise the customer on how to buy a new appliance (if a repair isn't possible)

You might also advise customers on energy efficiency and how best to improve their central heating systems.

Gas Service Engineers also carry out Landlords' safety checks in rented accommodation.
