Hi everyone

My Dad is doing up the house a bit and is trying to figure out what these wires are that run up the wall. They've always been in this state. He's wanting to know if he can rip them out or if he should leave them.

The one on the left, the "figure 8" shaped one, looks a bit like a telephone cable. It enters the room from under the carpet.

The fatter one on the right comes into the house from a hole through the concrete blocks. Not sure what's on the outside in that position but the electricity meter is in the general vicinity.

Sorry about the poor photo, let me know if a better photo will be useful.

Thanks
