Rolyberkin. None of the works have been tested as far (we were waiting until completion) All of the wiring is still visible in one of the two houses. The other is post-plaster. But can be accessed by lifting the floor boards in the right places and cutting out the plasterboard (not desirable, but possible) We’ve got one house fully open and everything is visible. The plastered house is a carbon copy of the one in which the wiring is still exposed. So this indicates the methods used. Any thoughts going forward?
I must admit I was being facetious! I would recommend you speak to your BCO and discuss your situation and ask their advice (they like that!) most councils will allow you to commission an EICR at your cost and pay an additional regularisation of works charge to comply with building regs.
