• No heating and/or hot water. This could be caused by a variety of things including failure of motorised valves or low water levels.
  • Pilot light going out. This could because the thermocouple needs replacing or it may because because of a blocked or faulty gas valve.
  • Condensate pipe freezing. During extremely cold weather the condensation in this pipe may freeze and cause a blockage this in turn causes a blockage which makes the condensate ‘back up’ into the boiler and cause a shutdown. If your condensate does freeze click here to see our tips 
  • Kettling. When lime scale builds up on your boilers heat exchanger and restricts the flow of water.
  • Losing pressure. The most common reason for losing pressure is that there may be a leak somewhere on the system.
  • Boilers which keep switching off. This can be caused by enough air in the system, closed valves, a broken pump or low pressure.
  • Thermostat issues. The thermostat could be incorrectly temperature fluctuating, dead batteries or could have a build up of dirt.
  • Leaking and dripping. Several issues could cause your boiler to leak water. The location of the leak would need to be found in order to identify the problem. 
  • Strange banging noises. If your central heating system is creating strange noises such as banging, whistling or gurgling sounds it may be because there is air in the system or maybe the system could need power flushing.
  • Radiators not getting hot. If your radiator is warm at the bottom and cold at the top, there may be air in the radiator which can be fixed by bleeding the radiator. If this is not the case, it may need a power flush to clear the sludge and dirt from the system.
