For Edwardian terraces in Penrhiwceiber with shared party walls in particular, eicr — electrical safety checks on a edwardian semi throws up a fairly predictable set of findings. Wiring generation on this stock is typically rewired 1970s–2000s; front-bay circuits and porch lighting frequently missed on partial rewires. Work in Mountain Ash is planned so that the disruptive part is as short as it can reasonably be. Anyone testing properly will reach the same conclusion.
The practical question for a Mountain Ash property is not what usually happens, but what this installation actually shows when it is tested. It rarely changes the price, but it does change the plan. You can spend a lot on eicr — electrical safety checks on a edwardian semi or very little. Which one is right depends on measurements, not on the quote.
