Currently the 10mm cable that the original land owner laid is just direct buried. When we did the excavations on site last month for the turning circle and retaining wall we laid down 30m of ducting from the edge of our plot to the dwelling entrance. For the sake of a few quid we will be laying ducting for the rest of the cable run.
Thanks for that tip regarding laying two cables, perhaps the current 10mm cable could be utilised somehow if it is fit for purpose.
Unfortunately, that would be highly unlikely!! That cable is a dead duck i'm afraid.
May be you can save it, and use for garden/ shed / garage, installations etc...
