cavity brick (early cavity construction), plasterboard-on-batten internally on some ceilings. Roof-space access is straightforward, loft cabling is easy — but plasterboard-on-batten ceilings mean second-fix downlight work needs careful joist mapping.
Two things dominate full property rewires on a 1930s semi in Caerphilly: ring finals extended into the kitchen or a rear extension without checking the R1+R2, and back-boiler removals leaving abandoned wiring in the airing cupboard. Both are known variables on this stock, and both belong on the quote — not the invoice.
We work across CF83 weekly and see the same patterns street after street. That means the quote reflects real experience of this property type, not a template price.
Focus on the porch or hallway, the consumer unit location, and the intended cable route. Usually 15–30 minutes on-site or a short photo set.
Priced against your 1930s 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 — roof-space access is straightforward, loft cabling is easy — but plasterboard-on-batten ceilings mean second-fix downlight work needs careful joist mapping.
NICEIC certificate, photo evidence of hidden work, Part P where applicable — all emailed the evening the job signs off.

Wiring generation on this stock is typically rewired 1980s–2010s; ring finals commonly extended without upgrading the CU. On a 1930s semi you should expect us to flag: ring finals extended into the kitchen or a rear extension without checking the R1+R2; back-boiler removals leaving abandoned wiring in the airing cupboard; loft-conversion feeds spurred off the upstairs ring rather than a dedicated circuit.
Materials and methods we spec on 1930s bay-fronted semi work: 18th Edition metal-clad CU; RCBO per circuit; additional CU for a loft or garage sub-main where the main board is short of ways. Everything is priced on the quote — nothing added on invoice.
Across CF83 the 1930s semi stock we've worked on shares consistent patterns: ring finals extended into the kitchen or a rear extension without checking the R1+R2. That local pattern is baked into the quote, not discovered on the day.
18th Edition metal-clad CU; RCBO per circuit; additional CU for a loft or garage sub-main where the main board is short of ways. All on the written quote.
Rarely a full rewire — usually a partial rewire covering the extension plus a CU upgrade so the new circuits are properly protected. We quote both scopes.
Two things: ring finals extended into the kitchen or a rear extension without checking the R1+R2, and the wiring generation — rewired 1980s–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.
Common enough that we work on this stock most weeks. new-build estates in Bedwas, traditional valley terraces in Senghenydd, and detached homes towards Abertridwr — the 1930s semi is a recognisable slice of that mix.
