Fuse box replacement in Horfield
A modern consumer unit with RCD protection on every circuit, fitted and certified in a day.
The Horfield pattern is the newer-board-older-wiring hybrid: a consumer unit swapped in the nineties or 2000s onto cabling from decades earlier, which passes the glance test and fails the insulation-resistance test. Board upgrades here start with testing what the board would feed, and the honest outcome is sometimes a staged plan: upgrade now with the worst circuit renewed, the rest scheduled. Where the wiring genuinely is sound, the 1930s semi gives the tidiest board swap in the city, meter and board sensibly co-located by the front door. The Horfield extra is the garage: many semis carry a decades-old switchfuse feeding garage lighting and a freezer, wired with optimism. When the main board upgrades, we bring that sub-main under proper protection at the same visit, which usually costs less than the call-out its eventual failure would.
The houses we see in Horfield
Predominantly interwar semis: cavity brick, accessible lofts, floorboards over joists, and original two-pin history long since overwritten by sixties and eighties rewires now ageing themselves. Kitchen extensions and loft conversions are steady, and the Victorian terraces of Bishopston's southern streets add an older layer. Ownership is long-term family with a renovation wave arriving as houses change generation.
Working in Horfield: the practical bit
The 1930s semi is the most cooperative house in Bristol to work on: lofts give clean access to the first floor, suspended timber ground floors take cables without drama, and cavity walls chase predictably. The electrical histories are the complication: many carry a sixties or seventies rewire now past its own lifetime, sometimes with a newer board bolted onto old cable runs, an arrangement that looks modern at the wall plate and is not. Surveys test rather than trust.
We cover all of Horfield, Bishopston, Ashley Down, Golden Hill, Gloucester Road corridor, Filton fringe and the streets between.
What fuse boxes involves
Replacing a fuse box (consumer unit) in Bristol costs £450–£750 excluding VAT and takes most of a day. That covers a new metal consumer unit with RCD or RCBO protection on every circuit, surge protection as the current regulations expect, full testing of every circuit it feeds, and the Part P certification. An old rewireable fuse board still works, but it cannot protect people the way a modern board protects them; this is the single highest-safety-return job in domestic electrics.
This is for you if
- Your board still has rewireable fuses or a wooden backboard
- The electrics trip and you have no idea which circuit or why
- A survey or EICR flagged the consumer unit
- You are adding a big load: an EV charger, an electric shower, a kitchen extension
- There is no RCD protection, so a damaged cable means a shock, not a trip
- The board is a plastic one from the 2000s and you want current-standard protection
What's included
- A survey of every circuit the board feeds before we quote
- A modern metal consumer unit with RCBO protection per circuit
- Surge protection (SPD) fitted as standard, not sold as an extra
- Main bonding to gas and water checked and upgraded where needed
- Dead and live testing of every circuit, with the results recorded
- Part P notification and the Electrical Installation Certificate
The standard we work to
Consumer unit replacement is notifiable under Part P; installed and certified to BS 7671 including surge protection assessment; main bonding to gas and water verified before energising.
