Belfast's Victorian and Edwardian terraced housing, built during the city's era as a major shipbuilding and linen manufacturing centre, 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 Belfast 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 a completion certificate confirming compliance with Building Regulations (Northern Ireland), from a registered electrician.
