Fair point, however it is 'most likely'' that 10mm will suffice. I
doubt anyone at wherever it is that the OP rings will have a clue
what he's on about anyway!

Yes, that occurred to me - getting through to someone that can answer
technical questions ain't easy.

Hmmm, you can, I'll stick to 10mm thanks! I can't see someone
rewiring there own house buying 100m of 16mm earth to use 3m of it
though!

A 50m reel isn't particularly expensive though, and you'll probably need
more than 3m to get to the water and gas pipes...
