Full Property Rewires on a post-war semi is shaped by cavity brick with plasterboard finishes, concrete lintels. The scope is standard once the physical routing is planned around that construction.
The awkward part of full property rewires on a Ystrad Mynach 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.
Post-War Semi properties are a distinctive part of the Ystrad Mynach housing mix — 1970s estates in Hengoed, traditional terraces in Nelson, and rural smallholdings towards Penpedairheol, particularly around Hengoed & Nelson. We work on this stock weekly.
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.
Priced against your post-war semi's specific construction, not a template. Route sketched, materials listed, no line-item surprises.
Diary planned for the access constraint that matters on this stock — good loft access, generous under-floor voids and a straightforward driveway make the physical work easy; the variable is always the cu generation.
NICEIC certificate, photo evidence of hidden work, Part P where applicable — all emailed the evening the job signs off.
Two things: kitchen refit added post-rewire, socket circuit no longer matches the original ring layout, and the wiring generation — rewired 1990s–2010s. Both go on the quote, not the invoice.
Not unless the quote says so. On period stock in particular we route through floors, lofts and non-original plaster; cornices, dado rails and original panelling stay intact.

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.
Beyond Ystrad Mynach itself, we regularly cover post-war semi work across Caerphilly, Bargoed, Pontypridd on the same fixed-price model — same materials, same certificate format.
Bottom line: post-war semi owners in Ystrad Mynach deserve a quote calibrated to c.1945–1965 construction, not a template. That's what we do, on every job.
