What you need to do is run some 3 core SWA from the C/U / fuse board to a outside switch panel like this. http://www.ebay.co.uk/itm/Toggle-Sw...Lighting&var=610206316885&hash=item48585a3cd1
Also it needs to be RCD/RCBO protected.
Will trace where the taped up wire goes and try and work out how it was originally wired. There must be a hole in the wall somewhere. Someone's spent time/money ripping it all out, god knows why
If it was wired in flex it was wired up wrong and they could of ripped it out due to not wanting it coming up when selling the house.
