If you are weighing up consumer unit upgrades on a bungalow at a Swansea address, the useful starting point is the age and history of the wiring. The stock is typically 1950s–1980s, walls are cavity brick, generous single-storey plan, easy loft access, and the practical constraint is that loft-run cabling makes rewires and cu upgrades genuinely easy — a bungalow is often the cheapest full house to rewire. Where the answer is to leave it alone for now, that is exactly what we will tell you. It takes minutes to confirm and saves hours later.
The practical question for a Swansea property is not what usually happens, but what this installation actually shows when it is tested. It rarely surprises us; it often surprises the previous quote. Consumer unit upgrades on a bungalow looks the same on every website. What differs is how it is scoped, and that is what this page is about.
