Boiler Ignition Fault Repair

What boiler ignition fault repair covers

If your boiler is failing to ignite or stay lit, this service is designed to find the fault quickly and get the system running safely again. It typically includes:

• Checking fault codes and boiler behaviour to narrow down the issue
• Testing ignition and flame detection components (for example ignition electrode and flame sensor)
• Checking related controls and safety circuits (such as fan proving, air pressure switch and PCB signals)
• Confirming adequate gas supply and correct operating pressures where applicable
• Inspecting for common contributing issues like condensate problems or damaged wiring
• Repairing connections or replacing failed parts with your approval
• Completing safety checks and functional testing before leaving

When this service is the right fit

This service is most relevant if:

• Your boiler is showing ignition related fault codes or repeatedly locking out
• You have no heating or no hot water, or both
• The boiler tries to start but fails, clicks repeatedly, or lights then shuts down
• The issue is intermittent and getting worse over time
• You need a clear diagnosis and a reliable fix rather than repeated resets

How the repair is carried out

The visit starts with a structured diagnosis: visual checks, fault code review and targeted testing. Once the cause is confirmed, you will be talked through the options, likely parts required, and what the repair will achieve. After the repair, the boiler is tested through normal operation to confirm stable ignition and safe running.

After the repair

You will be shown what was done and what to watch for. If the fault suggests wider issues (for example recurring condensate freezing, system debris, or overdue servicing), you will get practical next steps to reduce the chance of a repeat breakdown.
