I currently have sunken spotlights in my kitchen. I am in the process of removing some of my kitchen units and thus the spotlights contained within them. As the lights are wired through my attic, with my house in the format it is, I have difficulty getting access to totally remove the wiring for the spots in question. Would it be safe to terminate the ends of the removed spotlight wires on termination blocks, tape them up to prevent any potential fire hazard and simply place them behind my plasterboard wall and plaster over to hide? Thanks in advance.
