There is a short version and a long version of consumer unit upgrades on a 1930s semi. The short version: test it, then decide. Roof-space access is straightforward, loft cabling is easy — but plasterboard-on-batten ceilings mean second-fix downlight work needs careful joist mapping. Work in Swansea is planned so that the disruptive part is as short as it can reasonably be. That is checked with instruments, not by eye.
We take the view that materials matched to the stock should be established before a price is written, not after. That is slower to quote and cheaper to complete. That detail is what a proper survey is for. Before booking consumer unit upgrades on a 1930s semi anywhere in Swansea Council, it is worth knowing which parts of the job are fixed and which depend on your property.
