From £499 – supply, fit, testing & certificate
Replace your old fuse box with a modern 18th Edition consumer unit. CA Electrical & Building Services carries out consumer unit replacements and fuse board upgrades across Middlesbrough, Stockton-on-Tees, Yarm and Hartlepool. Established 2008.

Old fuse board removed and a new 18th Edition consumer unit fitted, tested and certified.
Typical UK prices for a consumer unit upgrade in 2026 are about £350–£800. Our fuse board upgrades start from £499 – fully tested and certified.
Bigger homes, extra circuits or remedial work (such as earthing and bonding upgrades) can add to the cost – you'll always get a clear price before work begins.
Fuse boxes with fuse wire offer far less protection than modern circuit breakers and are awkward to reset.
RCDs cut the power in a fraction of a second if there's an earth fault, helping protect against electric shock and fire.
A board that keeps tripping can point to faults or an overloaded, outdated consumer unit.
Adding an EV charger, electric shower or other big load often needs a consumer unit upgrade first.
Safe isolation and removal of your old fuse board or consumer unit.
A modern consumer unit with RCD or RCBO protection, fitted to current wiring regulations (BS 7671).
Every circuit tested before and after the swap.
Electrical Installation Certificate provided and the work notified to building control under Part P.

Warning signs include old rewireable fuses (fuse wire), no RCD protection, frequent tripping, a wooden or plastic-backed old board, scorch marks or buzzing. You may also need an upgrade before adding an EV charger or electric shower.
