There is no single price for consumer unit upgrades on a edwardian semi in Swansea, and anyone quoting one before looking is guessing. On this stock the sensible answer is metal-clad 18th Edition CU — matched to the wiring generation, not a lift-and-shift from a new-build brochure. Owners in Swansea often ask whether this is a repair or the start of something bigger. Testing answers that; opinion does not. For coastal terraces and detached homes in Mumbles and Sketty that detail matters more than it does elsewhere.
We do not upsell a full replacement where a component is at fault, and we do not patch something that has reached the end of its life. We would explain the same thing on site, just with the board open. This page is for anyone in Swansea trying to work out whether consumer unit upgrades on a edwardian semi is their next job or next year's.
