Annual service checklist

Try to arrange your service during the summer months, before the traditionally busy autumn & winter season, when people start putting the heating on and there are more breakdowns.

The checklist below shows the key things you will have done during a full boiler service.

  A visual check to ensure your boiler still meets current standards

  Boiler fired to identify any working faults

  Boiler casing removed to check all main boiler components (burner, heat exchanger, main injector, spark/sensor probe).

  Checks to ensure flue terminals are unobstructed and internal flue components are sealed properly

  Gas valve adjusted to check that burner is combusting efficiently and properly
  (normally using a flue gas analyser).

  Inside casing surfaces cleaned

  Boiler parts cleaned if necessary

  Gas tightness test conducted to ensure no leaks

  Boiler casing put back on - check that properly sealed

  You should will recieve a service report if requested that shows everything the engineer has done to
  maintain your boiler.
