Common causes of why there’s no power coming to your boiler
One of the leading causes of no boiler power is a blown fuse.
This can occur if the boiler is old or there is a power cut. Unless the fuse is functioning properly, the boiler won’t turn on.
A gas engineer will need to examine the boiler and replace the fuse if necessary; followed by a test to check whether the issue has been successfully resolved.
Fuse box tripping
The RCB (fuse box) keeps the electricity running through your home. However, one small fault from the box can cause a boiler power shortage.
It would be wise to check your fuse to make sure that all of the switches are facing the right way.
If just one switch is down, you’ll get no power, but a simple flick upwards should restore power to your boiler.

Boiler not firing up? it may be down to a circuit board failure (PCB).
