Main service cables hidden

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!

  • well, if it was done before 1988 or so when all this zones malarky came in, it might have been compliant That is academic, as now you have uncovered them they cannot simply be re-covered. But as they are on the DNO side of the meter, if I understand you right, then you cannot simply disconnect and reroute them, and depending how it is fed, there is a risk that neither can the DNO without turning part of the street off.

    They would be OK visible, or more than 4 inches deep, or behind something un-drillable, but with modern power tools this third option may not be as easy as it was 20 years ago. metal trunking looks a bit industrial but reminds folk there is wiring within.

    A not quite compliant but safer thing to do would be to cover the opening with something that indicated cables within - "caution cables beneath this wooden panel " type thing.
