If a previous certificate exists, eicr — electrical safety checks on a post-war semi usually starts by checking whether it still reflects reality. The stock is c.1945–1965, walls are cavity brick with plasterboard finishes, concrete lintels, and the practical constraint is that good loft access, generous under-floor voids and a straightforward driveway make the physical work easy; the variable is always the cu generation. The order of work matters: isolate, test, explain, then price. Skipping the middle two is how people end up paying twice. Around SA1–SA7 it is the single most common reason a job runs long.
Where an installation has been extended over decades, the sensible approach is to establish a baseline before adding anything else to it. For coastal terraces and detached homes in Mumbles and Sketty that detail matters more than it does elsewhere. Eicr — electrical safety checks on a post-war semi is one of the more commonly misquoted jobs, largely because nobody tests before pricing it.
