Some may remember my question from a week or so ago about fitting a
gas meter box. I have fitted the box and it all went fine, no
calamaties with the whole wall collapsing and it has turned out pretty
neatly.

My next question relates to the earth wire which must be run to a
point just after the meter. Do I need to sleeve this wire as it comes
through the wall or will the PVC coating suffice?

The cable doesn't need sleeving for it's protection, but you
do need to prevent any leaking gas getting into the wall.

Why are you running the earth through the wall anyway?
Just connect it to the pipe on the inside, as it emerges
from the sleeve.
