Consumer Unit Upgrades on a 1930s semi in Caerphilly is a physical problem before it is an electrical one. The stock is c.1925–1939, walls are cavity brick (early cavity construction), plasterboard-on-batten internally on some ceilings, and the practical constraint is that roof-space access is straightforward, loft cabling is easy — but plasterboard-on-batten ceilings mean second-fix downlight work needs careful joist mapping.

That shapes every line on the quote. We survey the porch or hallway, 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.

What to expect

03
Booked around access
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.

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.

What we build into every quote

Common 1930s semi findings we flag before quoting: ring finals extended into the kitchen or a rear extension without checking the R1+R2.
Access constraints priced into the diary — a 1930s semi in Caerphilly isn't the same working day as a new-build with an empty garage.
Wiring generation on record (rewired 1980s–2010s) so the quote reflects what's actually in the house, not what the brochure assumes.
Fixed price at quote stage, calibrated to c.1925–1939 construction — not a generic South Wales rate.

Construction & access

Roof-space access is straightforward, loft cabling is easy — but plasterboard-on-batten ceilings mean second-fix downlight work needs careful joist mapping.

Wiring generation & likely findings

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 we spec

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.
