OK, some time ago I rewired my house, with a sparky installing a new CU on the wall of my understairs cupboard and myself then putting in the new rings and lighting circuits by myself. All of the cables reached the understairs cupboard via the void under the wooden hallway floor. Unfortuntately the cupboard under the stairs has a concrete floor so as a temporary thing I simply brought the cables up in the hallway (the wooden floor is soon to be replaced) then straight into the cupboard under the stairs. This resulted in the cables laying across the floor of the cupboard before going up the wall to the CU. Obviously I have not been using the cupboard under the stairs whilst the cables were in this state but now I am about to replace the hallway floor so at the same time I want to put the cables in thier permanent position. The attatched diagram should crudely show the current situation:
