Boiler wired from lighting circuit

[concerned321]

Hello. I'm just looking for a bit of advice.

I had a new boiler fitted a few months ago. An electrician came and wired it up and left me a Minor Electrical Installation Works certificate.

ive just had a plumber round to check the work and he says the electrician has wired the boiler from the lighting circuit and he shouldn't have done this because it is a 6 amp switch in the fusebox.

The electrician says it is ok because he has fitted a switch next to the boiler with a 3 amp fuse in it.

could you tell me which one of them is right please?

Many thanks

unconventional, but not a problem. a bathroom fan is usually fitted with a 3A fuseand that's wired from the lighting.

As above but Just for curiosity, is that circuit on an RCD or RCBO?

but does it need one? is cable buried< 50mm in wall/s?. does boiler blurb specify fitting one?

Presumably the load on a gas boiler is pretty low due it being just switching?

Further to the above. Presumably, if your lighting circuit tripped out you'd lose your heating at the same time.

The sparky is correct!

that short comment reminds me of the classic comment " the sherrif's a Ni**er".

Not necessarily, I'm just curious !
