Consumer Unit Upgrades on a post-war semi in Merthyr Tydfil is a physical problem before it is an electrical one. The stock is c.1945–1965, walls are cavity brick with plasterboard finishes, concrete lintels, and the practical constraint is that good loft access, generous under-floor voids and a straightforward driveway make the physical work easy; the variable is always the cu generation.

That shapes every line on the quote. We survey the hallway or garage, the cable route and the consumer unit location before pricing — because on this property type the standard scope is only standard once you know what you're working around.

Construction & access

Good loft access, generous under-floor voids and a straightforward driveway make the physical work easy; the variable is always the CU generation.

Wiring generation & likely findings

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 we spec

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.

What we build into every quote

Wiring generation on record (rewired 1990s–2010s) so the quote reflects what's actually in the house, not what the brochure assumes.
Fixed price at quote stage, calibrated to c.1945–1965 construction — not a generic South Wales rate.
Certificate at the end, delivered the same evening, in the format your next EICR or agent will expect.

FAQs — post-war semi in Merthyr Tydfil

What materials do you spec on this property type?+

metal-clad 18th Edition CU with RCBO per circuit; SPD retrofit; shower feed uprated to 10mm where the run length demands it. All on the written quote.

Is a CU swap enough for a post-war semi, or do I need a rewire?+

A CU swap is usually enough. We test every circuit at survey and only recommend rewiring where the readings genuinely justify it.

What's specific about consumer unit upgrades on a post-war semi?+

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.

Will the work affect any original features?+

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.

How common is a post-war semi in Merthyr Tydfil?+

Common enough that we work on this stock most weeks. stone-built terraces in Heolgerrig and Cefn Coed, ex-council semis in Gurnos, and newer developments around Pant and Dowlais — the post-war semi is a recognisable slice of that mix.
