There is a short version and a long version of consumer unit upgrades for home buyers. The short version: test it, then decide. That is the lens we quote through. The regulations move; installations do not. Part of the job is explaining which differences actually matter and which are simply age. That is checked with instruments, not by eye.
This is routine work carried out weekly across CF47–CF48, so the process is settled: check NICEIC certificate, photo evidence, record it, quote it, complete it, certify it. That detail is what a proper survey is for. Before booking anywhere in Merthyr Tydfil County Borough Council, it is worth knowing which parts of the job are fixed and which depend on your property.
