Boiler Not Firing Up
Boiler Not Firing Up
Boiler not firing up in Kingston upon Thames or South West London? Gas Safe engineers diagnose no-ignition faults properly instead of resetting it and hoping.
About this service
Boiler Not Firing Up in South West London, done properly the first time
A boiler that will not fire is usually one of a short list: low system pressure locking it out, no gas at the appliance, a failed ignition lead or electrode, a faulty gas valve, a blocked condensate trap holding the pressure switch open, or a PCB fault.
Repeated resetting is the worst thing you can do — most lockouts are the boiler protecting itself, and forcing repeated ignition attempts can flood the combustion chamber.
We test in order: pressure, power, gas supply and pressure, condensate, ignition components, then controls. You get the actual cause and a fixed price to fix it, plus an honest view on whether the repair is worth it on an older appliance.

Frequently asked
Your questions, answered
Why does my boiler lock out and show a fault code?
A lockout is a safety response — no flame detected, overheat, low pressure or a fan/pressure switch fault. The code narrows it down but does not confirm the cause on its own.
Can I reset it myself?
Once is reasonable. If it locks out again, stop and call us — repeated resets can make the fault worse and can be unsafe.
Will you have the part with you?
We carry common ignition leads, electrodes, sensors and pressure switches. Brand-specific gas valves and PCBs are usually next-day.
