What boiler is it? Are you sure it’s live neutral and earth?
 
Boiler is 10+ years old no name on it as I can find was in when we moved into it in 9 years ago and definitely only 3 wires in flex
 
Is it a combi boiler? - these only require a live neutral and earth. What is it you’re trying to achieve?

Blood and stone spring to mind. What are you wanting to do? Can you post a photo of said boiler?
 
If they are the only wires to the boiler, then the Live will be a Switched Live, won't it?
Otherwise it would be on all the time.

It's a Glow Worm Space Saver MK1 from the 1970's to 1980's. It only needs a switched live, neutral and earth, as per the diagram posted by @EFLImpudence

It has a permanent pilot light, so no electronic ignition. No pump overrun either.

no name on it as I can find

What does it say here?

yup, indeed but there is a school of thought that suggests that it won't be very efficient ... :whistle: lucky if it's > 70%
