If a previous certificate exists, full property rewires on a post-war semi usually starts by checking whether it still reflects reality. Materials and methods we spec on post-war semi work: metal-clad 18th Edition CU with RCBO per circuit; SPD retrofit; shower feed uprated to 10mm where the run length demands it. Where an installation has been extended over decades, the sensible approach is to establish a baseline before adding anything else to it. That holds whether the property is owned, let or being sold.
Newport sits inside the area we work daily, so a follow-up visit is not a logistical problem if one is needed. Two properties on the same street can differ on this entirely. Full property rewires on a post-war semi is one of the more commonly misquoted jobs, largely because nobody tests before pricing it.
