Cardiff's Victorian terraced housing, built rapidly during the city's era as the world's largest coal-exporting port, typically predates modern wiring regulations by well over a century and has usually been rewired at least once, often only partially.
Why a site visit matters
Given how many Cardiff terraces have a patchwork wiring history, an electrician genuinely can't give an accurate full-rewire quote without inspecting the property first.
What's actually included
A full rewire should include a new consumer unit, complete new cabling, socket and switch replacement, and an EICR at completion, from a NICEIC or NAPIT registered electrician.
