I don't think you'll need three phases. It sounds like you could get
away with having the EB put in the new one and take the old one out.
Be careful if they suggest using a three phase meter. EBs bill to 3x the
highest consumption phase.

Richard

It must be _very_ EB-dependent- unless your fuse is remarkably small-
even
when adding a fairly large load to an existing supply (this is an
outdoor
centre with 4 electric showers, 3 immersion heaters, various small
kitchen
electrics, lighting, some additional electric heating (all on a single
phase 100A fuse)), the local EB (Hydro) came out, had a look at the
cables,
and said "We'll just stick a bigger fuse on for you"... I've
never had
the
misfortune to have to submit an 'additional load form', especially to
fit
something not much bigger than an immersion heater, and about the same
size
as an electric oven... you don't have a gas cooker but cable for an
electric one by any chance?

I think you maybe ought to get a second opinion- either post to uk.d-i-y
if
you don't mind some donkey-work, email me once you get more details on
your
existing fuse and say what you currently have connected, or ask another
electrician (with the last option being best by far). The EB will very
unlikely have to upgrade _anything_ to give you another phase, unless
your
road's cables are on their last legs anyway. Are you _certain_ that he
did
contact the EB, and isn't just having you on? Have you spoken to them?
This 'balanced 2-phase' bit has me convinced something is not quite
pukka
about this...

If you do have to go 3-phase, and they want you to guarantee balanced
loads
(and I have to say at this point that someone is trying to make money
out
of you or doesn't know what they're talking about), then you would have
to
worry about 3-phase X10, if you keep all your existing equipment on one
phase and only have a shower on the other, you don't have to worry about
it- single phase is one of the three phases anyway, there's nothing
special
about it.
But, until I see evidence to the contrary, I have to reckon that someone
is
'at it', having _never_ seen a domestic 3-phase supply required.
I'll be speaking to someone who works on the technical side of the local
EB
tonight- I'll ask him what he reckons...
