The Swansea version of this job is shaped by the local housing: coastal terraces and detached homes in Mumbles and Sketty. 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. There is a version of this job that is quick and a version that is not, and the difference is almost always focus on the hallway or garage, the consumer unit. A short survey tells us which one your property is. Focus on the hallway is the part worth confirming rather than assuming.
Owners in Swansea often ask whether this is a repair or the start of something bigger. Testing answers that; opinion does not. Which is why the price follows the test rather than the other way round. If you are weighing up consumer unit upgrades on a post-war semi at a Swansea address, the useful starting point is the age and history of the wiring.
