While investigating dampness issue I found a hole under the shallow footings (200 year old house). Tried pushing a drain pole down to see if it went all the way into the house and therefore a possible cause of the dampness, and found that it came through in the meter cupboard near the mains incomer. Lifting the floor here it looks like a lot of the base of the wall here has eroded away and there is a hole about a half metre going out through the wall under the ground in the same area.

I'd like to be able to put some blocks in under the floor here and pour some concrete to stabilise the base of the wall and also do the same outside, but I am not sure if I can pour concrete around an incomer, or if I should contact the Electricity network people?

Ideally, it would be better if the meter was on the outside and coming in a bit higher up so that it didn't interfere with the footings, but not sure if they would entertain that.

Probably a bad idea to poor concrete directly onto the the cable as it obviously has small stones would could br pressing against the cable, and if there is any movement in the concrete, then as this will have stuck itself onto the cable, this could result in stress being applied to it.

Only thing I can think of atm is a bit of black underground flexi duct slit along the length, popped over the cable, and closed up again with tie wraps, and poor around the outside of that
 
Thanks Adam, was doing a bit of a search myself about concrete/cement and cables and found the below basically saying that the energy company will do their nut if you pour concrete around their cables. Allegedly it can corrode them.

I wonder if I can shield the cable with a half pipe or something and fill the hole around the cable with pea gravel and the other side of the pipe with concrete so that the cable is not in contact with the concrete.

Thanks. Just checking that I was clear enough that this cable is the incoming cable from the electricity supply network. There is no fuse/circuit breaker prior to this so I am a bit wary of getting too close to it and I am not sure if I am allowed to mess with the cable owned by the network.

If I was to tie strap on conduit it would be difficult to do this without touching against it and it would be difficult to get tie straps around it as its running under the foundations of the house.
 
Old cable gets brittle and in some instances can “snap”. I wouldn't go any where near it.
Yes, I was a bit wary of getting to close and personal with it, even putting aside the fact that you are not supposed to mess around with the power company cable. I mean its a live cable capable of carrying well over 100 amps, there's no coming back from that if it goes wrong!

What I did in the end was to build up a small stage with blocks and concrete from the ground below up to just below the level of the cable and around the sides where it comes in, then I poured some pea gravel around the cable so that I wouldn't be touching it with any cement. Its setting now but that should stop the base of the wall there from continuing to erode and I should be able to fill the gap around the under the footings without touching the cable.

I suspect when they have fitted this cable many years ago they have just battered a hole through under the base of the wall, not realising how shallow the footings were, and over time water has been coming in there and eroding the base of the wall.
