Eicr — electrical safety checks on a 1930s semi is one of the more commonly misquoted jobs, largely because nobody tests before pricing it. Materials and methods we spec on 1930s bay-fronted semi work: 18th Edition metal-clad CU; RCBO per circuit; additional CU for a loft or garage sub-main where the main board is short of ways. A written record matters as much as the work. Anything we find at a NP10–NP20 address is documented in a form you can hand to someone else. That detail is what a proper survey is for.
If you have had conflicting advice, it is usually because someone quoted without checking wiring generation on record (rewired 1980s–2010s) so the quote. Two electricians looking at the same readings tend to agree. That is one reason our price does not move after the survey. A short guide to eicr — electrical safety checks on a 1930s semi for Newport property, written by the person who would do the work.
