Hmm... the last ducting I was supplied for new cable work was black as was the *hockey stick* for the meter box. Things change:-) In '95 yellow Elephant trunk flex was OK for gas. I think it now has to be pierced.
The 11KV joint failure which involved digging up my field yesterday had
3 orange cables heading off to the neighbour's transformer but I don't know if they were just tails or ran all the way.
It's just that I've seen blue (water), yellow(gas) red and black pipes going in to a big site. I didn't know what the last 2 were, so assumed that electricity would be red. Brighter colours make more sense.
Not quite what we're talking about here, but the professionals can get it seriously wrong

Many holes and trenches were dug around large parts of Dundee, involving multiple road and lane closures. This lasted for several weeks, then they announced the cable was faulty. As it says, they'll have another crack at it next year, but meantime Scottish Water have dug much of the same road up, with great disruption, to lay new water pipes.
Thanks, the only cable that I have buried in my garden happens to be a fibre optic one. Though not strictly necessary, it is inside blue plastic water pipe just for physical protection. Other coloured piping is harder to buy.
Very possibly. But my buried water supply pipe from the stopcock was black 20mm MDPE, before I changed it to blue 25mm, and i think 20mm was not generally used for above ground.
