The starting question with emergency callouts on a victorian terrace is always the same: what does the existing installation test at? Cable routing is planned around the front bay, the hallway and the ceiling voids — not the walls. Where previous work has no certification behind it, we test it rather than take it on trust. That is the difference between a guess and a measurement.
This is routine work carried out weekly across CF45, so the process is settled: check wiring generation on record (rewired 1970s–1990s, often part-upgraded, record it, quote it, complete it, certify it. That holds whether the property is owned, let or being sold. We take a steady number of emergency callouts on a victorian terrace enquiries from Mountain Ash each month, and the pattern is fairly consistent.
