Hole and water ingress at mains incomer

[Kaymo]

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.
