Have we decided that you really have two different *phases*

center tapped transformer).

Four wires on the power poles in the street, being a three phase
supply. We have three wires leading from the street, and two power
meters, plus a third meter for the off peak water supply.

I'll ignore the comment about power meters as you can get
power meters with all sorts of internal topologies (i.e.,
I can't deduce anything from that).

So, does *your* house have "phases" A and B dropped to it;
your neighbor gets B & C; *his* neighbor C & A; the large
*business* at the end of the block A B & C, etc.?

My neighbour appears only to have one phase. He commented to me that he
remembered that the previous owner of my property had got a second phase
installed, but didn't know why.

So, this is a way of providing you with enough "supply"
to match your needs?

E.g., here, if you need more power, you upgrade your entire
service. I.e., a 60A service might be upgraded to 100A;
100A to 200A, etc. In each case, all of the conductors
coming into the house are increased to a higher ampacity.
(you appear to be able to just "add another leg"?)

Presumably the power company tries to balance phases.

OK.
