This page covers for property in Mountain Ash and the surrounding CF45 postcodes, in the order the work happens. Everything else — brand of gear, exact scope, upgrade suggestions — is downstream of that. The regulations move; installations do not. Part of the job is explaining which differences actually matter and which are simply age. We would say the same to a family member.
Properties around Mountain Ash that have changed use — a room converted, an extension added — usually need a wider look than the original request implies. You will get the plain version, not the technical one, unless you ask. Ask three electricians about consumer unit upgrades for warehouses & trade units and you may get three answers. Ours is based on what the readings say.
