Consumer unit & fuse box replacement
Swap an old, unprotected fuse box for a modern consumer unit with RCD/RCBO protection — safer, compliant, and tested. NICEIC-certified across Essex & London, usually done in a single visit.
Why upgrade your fuse box?
Your consumer unit is the heart of your electrics — it distributes power and, just as importantly, cuts it off when something goes wrong. Older boards often lack the protection a modern home needs, leaving you exposed to electric shock and fire risk.
Signs you need a new consumer unit
- An old board with rewireable (ceramic) fuses rather than breakers
- No RCD protection (no "test" button), or a single RCD that takes out the whole house when it trips
- A wooden or older plastic enclosure (current units are metal-clad)
- Scorch marks, a burning smell, or fuses/breakers that keep tripping
- Adding an EV charger, an extension, or a rewire
What's involved
We isolate the supply, fit a modern metal consumer unit with the right RCBO/RCD protection for each circuit, then test every circuit and issue your certificate. Where needed, we'll sort earthing and bonding at the same time so the whole installation meets current regulations.
How much does it cost?
A straightforward consumer unit replacement typically runs from around £450–£750 across Essex and London. Extra circuits, relocating the board, or remedial work found during testing can add to that. Get a guide price from our instant estimate tool, confirmed with a free visit.
