Lol, compared to the neighbours install it really is a work of art!
It was only when I was repairing a fence post that I noticed the neighbours identical wire stapled against it, otherwise I'd be querying this would you all also!
As it was the exact same wire as next door, I stopped worrying about it. Like you say it could be a DIY job as I doubt Virgin would have dug underground to the extent. I might catch up with the neighbour and check if he knows what it might be.
I’ve an attached an image, it’s the same wire but in black.
Given it's leaking/broken you have missed the boat on protecting it from damage and now should replace the pipe and ideally dig out deeper. Unless you're using it as a soakaway. You won't really get a better opportunity than this to sort it out!
Regarding the concrete it's not recommended in case of movement and you're supposed to lay it on gravel to allow it to flex slightly.
