you have to establish where it is fed from , it could well be a direct circuit from your consumer unit , and if it is then removing its fuse and disconnecting its cables could well be sufficent , however it could be a spur off your sockets , or if there is 6 cables in , 2 reds 2 blacks and 2 earths then it is directly in your sockets , so really good insulation and seperation is required, but it can be done, if 6 cables then join up your 2 reds to each other , join up your blacks to each other and your earths to each other too, to keep your ring main constant, and if you sell up then let your buyers know that the cables are there.
