My gas boiler is not working what should I do?

Take a look at our troubleshooting tips before booking a repair with us.

 If your boiler is in working order, please book a boiler service to avoid a cancellation or charge.

No heat or insufficient heat 

  • Is the electricity supply to the system switched on? Check the fuse on the system isolator. If you change it, use a 3-amp fuse only.
  • Is the timeclock control set correctly?
  • If the boiler has a selector switch, have you selected 'heating'?
  • Is the boiler thermostat on the setting you require?
  • Have you reset your boiler? Always reset in accordance with the Manufacturers User Instructions.
  • If you have a room thermostat, is it set to the room temperature you require? When a room reaches the temperature set on the thermostat the radiators will cool.
  • If you have a wireless programmable room thermostat, do the batteries need replacing?
  • Is the natural gas turned on at the meter?
  • If you have a Pay As You Go meter, is your credit low?
  • If your boiler has a pilot light, is it lit? Always relight in accordance with the Manufacturers User Instructions. 
  • If the radiator is hot at the bottom only, it may need to be bled.
  • If you have thermostatic valves fitted at your radiators, are they at the settings you require?
