Would value advice on this one. Family member needs a CU change. Old wylex at the mo. Considering doing it for cost esp as he's putting us up for a few days. As I am not self employed I am not sure how to go about the paperwork side of things. I was going to test the property and provide a cert from a photocopy of the sample in the BRB along with sched of inspections and test results etc. I guess it still needs to be notified to LABC etc what sort of costs would be incurred in that?
