Common boiler issues we can repair

The boiler shuts off unexpectedly
This could be due to low water pressure, thermostat issues, or a lack of fuel. It's often a safety feature to prevent further damage.
There’s no heating or hot water
This usually indicates an issue with the thermostat, pressure, or a broken valve, preventing proper heat distribution.
The boiler is leaking wate
Leaks may stem from worn-out seals, corrosion, or pressure-related issues, requiring immediate attention to avoid water damage.
The condensate pipe has frozen
In cold weather, the external condensate pipe can freeze, blocking proper drainage and causing the boiler to shut down.
Error codes are flashing on the display panel
These indicate specific faults within the system, ranging from electrical malfunctions to gas supply problems.
The boiler makes loud, frequent banging or kettling noises
This often happens due to a build-up of limescale or air in the system, causing pressure fluctuations and overheating.
The thermostat isn't working properly
If the thermostat malfunctions, it can't accurately measure or control the heating, resulting in either no heat or overheating.
The boiler pressure is low
Low pressure reduces the system's efficiency and could be due to leaks, valve issues, or recent bleeding of radiators.
The pilot light keeps going out
A faulty thermocouple, gas valve, or a draft can cause the pilot light to go out, preventing the boiler from igniting.
Radiators are not heating properly
This could be due to trapped air in the radiators, sludge build-up, or a fault in the pump or valves, restricting heat flow.

Why repairing your gas boiler is a smart choice

  • Improved Reliability: A boiler in good repair is less likely to break down, especially during the colder months when you need it most.
