Boiler Problems
Common Boiler Faults We Fix
We repair common boiler faults across different makes and models. Tell us what the boiler is doing, and include any visible fault code when booking.
Pressure Loss and Leaks
Repeated pressure drops may point to a leak, valve problem or another system issue. We diagnose the cause before recommending a repair.
Fault Codes and Ignition
Fault codes help narrow down the problem but still require proper diagnosis. Ignition faults can prevent the boiler from firing safely.
Frozen Condensate Pipe
Cold weather can freeze external condensate pipework and stop a boiler operating. We check the pipe and the wider system before restarting it.
Pump and Valve Faults
Circulation pumps and internal valves can fail or become restricted. This may leave parts of the system cold or stop heating altogether.
Banging or Gurgling Noises
Unusual boiler noises can indicate trapped air, circulation problems or another internal fault. We investigate before replacing any component.
Repair Visits
How Our Boiler Repair Visits Work
Every visit starts with diagnosis. We do not guess at parts or begin chargeable repair work without first explaining what we have found.
- We diagnose the fault first. The engineer checks the boiler, controls and relevant heating components.
- You receive an honest explanation. We describe the problem in plain language and outline the sensible repair options.
- A fixed price is agreed. You know the repair cost before the chargeable work begins.
- We repair it during the same visit where possible. Some faults may require a return visit if a specific part is needed.
- We leave the area tidy. The boiler and heating system are checked before the visit is completed.

Common Questions

It depends on the boiler's condition, the fault, the likely repair cost and whether further failures are expected. We assess the specific boiler and explain whether repair or replacement appears more sensible.
