Leeds is one of the fastest-growing cities in the UK, with a housing stock that spans Victorian back-to-back terraces in Hyde Park and Harehills, Edwardian semis in Chapel Allerton, inter-war housing in Morley and Pudsey, and modern developments in Kirkstall and the city centre. Many older properties across the city still have electrical installations that predate current regulations.
Under BS 7671:2018+A4:2026, Regulation 421.1.201 requires that consumer units in domestic premises be a type-tested coordinated assembly housed in a non-combustible (metal) enclosure. BS 7671 also requires 30 mA RCD protection for socket-outlet circuits and cables concealed in walls — making modern metal consumer units with RCBOs the standard across Leeds.
This guide covers everything you need to know about consumer unit replacement costs and requirements in Leeds — whether you are a homeowner in Headingley, a landlord managing HMO properties near the universities, or an electrician working across West Yorkshire.
