My father has said he has a 415V sticker on the feed into his meter box.
From what he's told me there is the normal arrangement of master fuse,
meter, then into the house to the consumer unit. The house was built in
1985ish and is detached. I've never seen inside the meterbox myself,
only the consumer unit, which looked like a normal run of the mill row
of circuit breakers with one master at the end, 100A. If there were
three phases in the meterbox I'd expect his description to include a lot
more. Now the previous owner did have an ironwork hobby with "high
powered equipment", but he was a very frugal sort and I doubt he would
have got three phases installed if he didn't absolutely have to - mind
you I believe he was the first owner of the house and designed it
himself, so maybe it's just as cheap to get three phases when building
the property? The reason this has come up is they've just had a 10kW
electric shower fitted (used to run from the hot water tank, but that
one wa
s
old and leaky) and are considering replacing their ageing oil boiler
with an electric one, which the electrician fitting the shower warned
would require a relay to switch off the boiler so it didn't run at the
same time as the shower as he'd run out of juice. When he saw 415V he
was wondering if he infact had more phases available.

You could well be right, there might or might not be 3 phase available.

It's very unlikely that there would be a 415V sticker if it wasn’t.

If the current electrician cannot advise, then you need someone who works
on (small) industrial sites.

Or he could just check if there is 3 phase there.

Sounds like perhaps the 3 phase meter has been taken out and replaced with
a single phase one.

Easy to prove.
