Signs your boiler needs a repair

No hot water or heating Your boiler appears to be running but is producing no heat or hot water — the most common sign of a fault.
Pressure keeps dropping If your boiler pressure falls below 1 bar repeatedly, there is likely a fault or a leak somewhere in the system.
Unusual noises Banging, kettling, or whistling often indicates limescale build-up, air in the system, or a failing pump.
Fault codes on display Modern boilers show error codes when something fails — these need a Gas Safe engineer to diagnose and clear correctly.
Boiler keeps cutting out A boiler that fires then shuts off repeatedly can indicate low pressure, a frozen condensate pipe, or a failing component.
Pilot light won't stay lit A pilot light that keeps going out usually points to a faulty thermocouple or a gas supply issue — both require a Gas Safe engineer.
