This page covers everyday accessory work on existing circuits: like-for-like replacements, grouped refreshes after decorating, practical USB upgrades where the current point allows, local spur or isolator replacement, and careful back-box tidy-up where the issue stays at the point itself.
Quick fit check: stay here for contained accessory swaps, loose plates, local spurs, isolators or grouped socket and switch refreshes. Use electrical repairs for one failed fan, spur or local point, and electrical fault finding for repeated tripping, heat damage, dead points with no clear local cause or intermittent power.
