Question for any sparks on here, or those versed in the regs. I excavated what used to be the old beer cellar entrance for my building, which is a pub conversion, in order to create some outside storage space. In the process of doing so, I exposed the electrical supply cable for the block. I had the distribution company come round and check it wasn't damaged, and that was all fine. I have now built some decking at the bottom of the excavated hole with a step that keeps the cable out of the way, so it's inaccessible, and re-installed the cellar doors over the hole to protect everything inside from the elements. The nagging doubt I now have after all this work is that there is some reg that says the cable has to be buried to be safe. I've read some secondhand reports that say that as long as the cable is visible and thereby protected from accidental damage it's fine, but wanted a more definitive, regs-based answer.
