I have a situation where the fuse box and service entry is located within a very small cabinet built into the outer leaf of what originally was an external cavity wall to a house. A garage was subsequently added on to the side of the house making the external cavity wall now an internal one. I have the job of installing a new consumer unit and would make sense to locate it on the cavity wall near to the original cabinet now inside the garage. I need to run cables from the consumer unit though the cavity wall and into the house. Problem is that the cavity is filled with polystyrene balls as insulation and I am aware of the plasticity probs this can cause. I would also need to run the cables vertically for about 0.5m to get from the consumer unit up to the level of the first floor void as the floor is higher than the flat garage roof.
What would be your views please of how to get the circuits from the consumer unit through the cavity wall and into the house for distribution? Obviously I would prefer to avoid heavy derating factors.
