You can spend a lot on full property rewires on a barn conversion or very little. Which one is right depends on measurements, not on the quote. That local pattern is baked into the quote, not discovered on the day. Neath properties near Swansea are covered on the same schedule, so a joint visit is often possible if a neighbour needs the same thing. Anyone testing properly will reach the same conclusion.
The practical question for a Neath 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. Full property rewires on a barn conversion sits somewhere between routine and urgent depending on what the property is doing right now.
