Evening All,
Came across this today and wondered what people's thoughts were.
An old terreced property had a single story extension at some point. Prior to the extension, I assume the main service cables ran up the outside wall and through to the meter above the back door.
The extension was built, I assume, over/around these cables. Today I came across them hidden under the plaster above the door (opposite side of the meter, where they would have ran above the outside door before the extension).
These should surely be protected, anyone drilling through them will have no protection device to protect them!
