The starting question with full property rewires on a period flat is always the same: what does the existing installation test at? That is the standard we quote to. If something falls outside what we can do properly, we say so and point you at who does it, rather than attempting it. On stone-built valley terraces in Heolgerrig and Cefn Coed it is worth ten minutes of anyone's time.
We take the view that NICEIC certificate, photo evidence of hidden work, Part P should be established before a price is written, not after. That is slower to quote and cheaper to complete. Around CF47–CF48 it is the single most common reason a job runs long. We take a steady number of full property rewires on a period flat enquiries from Merthyr Tydfil each month, and the pattern is fairly consistent.
