There have been several threads related to this but currently, how best
to go about moving the services?

Currently gas, water and electricity all arrive in the same trench and
now disappear under the extension floor to their meter boxes.

Extending supply cables means working live as there is no local means of
isolation. Also it has been hinted that supply companies are recording
the location of meter points. As a new meter was fitted just prior to
work starting, this is certainly possible.

Gas is easier as the feed can be clamped off.

I can deal with the water as this is behind the meter but how allowable
is putting all three services in the same trench and will the
electricity co. be happy with a buried duct and a draw rope as I don't
want to leave an open trench while they **** about?
