Quick (but lon winded explanation!) query that I thought someone may be able to help with. We have a bay window in our front room and want to install a radiator into the bay. This is being done tomorrow along with other plumbing & heating works. On clearing the room out I noticed (rather late in the day) that there is a plug socket in the middle of the wall where I want the rad. It has been added within the last 10 or 20 years and is surface mounted. Its not on the downstairs ring I don't think as it just had red, black and green going in and the wiring doesn't go on anywhere else. Basically it will be in the way of where the rad needs to go. If I pop the power off and take the surface mount box off and disconnect the wiring my intention was to lift the floorboard up and pull the wiring back into the floor cavity so that I can run the spur to another wall in the same room. What I need to know is what I should use and how to make the wires 'safe' whilst they temporarily reside in the floor cavity so that I can put the power back on? Insulation tape, connection block? Obviously I have to keep the red and black isolated and separate but is it safe to leave it in the floor cavity? Any help appreciated!
