cavity brick with plasterboard finishes, concrete lintels. Good loft access, generous under-floor voids and a straightforward driveway make the physical work easy; the variable is always the CU generation.
The awkward part of full property rewires on a Merthyr Tydfil post-war semi isn't the install — it's the route. Good loft access, generous under-floor voids and a straightforward driveway make the physical work easy; the variable is always the CU generation.
We map the route at survey, mark it up on a photo, and price against that specific plan. Nothing gets discovered mid-job that could have been priced at quote stage.
Focus on the hallway or garage, the consumer unit location, and the intended cable route. Usually 15–30 minutes on-site or a short photo set.

Wiring generation on this stock is typically rewired 1990s–2010s; kitchen and bathroom often updated separately with mixed board vintages. On a post-war semi you should expect us to flag: kitchen refit added post-rewire, socket circuit no longer matches the original ring layout; bathroom shower feed on a 6mm radial with an isolator hidden above the ceiling; outside tap or outside socket added on a spur without RCD protection.
Materials and methods we spec on post-war semi work: metal-clad 18th Edition CU with RCBO per circuit; SPD retrofit; shower feed uprated to 10mm where the run length demands it. Everything is priced on the quote — nothing added on invoice.
