Wales has a distinctive mix of housing, from Victorian and Edwardian terraces in the south to stone-built cottages and rural properties across the rest of the country. Carmarthenshire and the wider area around Swansea and the Valleys include many older properties that present challenges for boiler & gas engineer work. Stone walls, exposed locations, and older infrastructure all tend to push costs toward the higher end.
