Fuse Board Replacement Cost London 2026 — Consumer Unit Upgrade Prices
Fuse Board Replacement Cost London 2026 — Consumer Unit Upgrade Prices
Short answer: A consumer unit (fuse board) replacement in London costs £550–£950 inc VAT for a standard domestic property — fitted, NICEIC-certified, Part P notified, 6 years’ NICEIC warranty. The job takes 3–5 hours, leaves you with a fully RCD or RCBO-protected board, and clears most C2 items from a failed EICR in one visit. Call 07407 627542 or 07500 721453.
Prices include the unit, all RCDs/RCBOs, isolator switch, labour, full NICEIC certification, Part P notification, and 6 years’ NICEIC warranty.
RCD board vs RCBO board
RCD-protected board: Two RCDs protect groups of circuits. Cheaper. If one circuit faults, the whole RCD trips and 3–6 circuits go off at once. Most landlords go for this.
RCBO board: Every circuit has its own combined MCB + RCD. If one circuit faults, only that one trips. Adds £150–£300. Recommended for EV chargers/induction hobs.
Why London fuse boards fail EICRs
Pre-2008 Wylex/MEM/MK/Crabtree boards fail on 2 counts: no RCD protection on sockets/concealed cables (18th Edition breach), and non-fire-rated enclosure (17th Ed Amendment 3). Both produce C2 codes — unsatisfactory EICR, council-licensing trouble in Hackney/Tower Hamlets/Newham.
