Who needs a new fuse board
People book this when the old board is dated, overloaded or flagged on an electrical safety report, known as an EICR. We do the work for homeowners, landlords and small businesses in Peterborough, Cambridgeshire and the covered Essex towns.
- Old fuse wire boardsMany houses still have a wooden or plastic box with rewirable fuses. Those boards lack modern residual current devices, which cut the power if a circuit leaks. We swap them for a consumer unit with the right protection for today’s loads.
- Failed EICR on the consumer unitLandlords and buyers often need a new board after an EICR finds missing RCD cover, damaged busbars or circuits that no longer match the labels. We replace the unit and retest the circuits that feed from it.
- No spare ways for new circuitsAn EV charger, solar inverter, electric shower or extra kitchen sockets often needs a spare way. If the old board is full, we fit a larger consumer unit so the new circuit can land cleanly.
- Shop and office boardsSmall commercial premises in Witham and Maldon still run lighting and sockets from a domestic-style board. We replace those units where the load has grown or the old fuses no longer suit the installation.
What happens on the day
Power is off while the board is changed. We talk you through the outage before we isolate the supply.
- Arrival and isolationWe confirm the written price, check the meter tails and isolate the supply. Furniture and stored items in front of the cupboard need to be moved so we can work at the board.
- Fitting the new consumer unitThe old fuse board comes off. We mount the new consumer unit, land the tails and earth, and connect each circuit to the correct breaker. Ways are marked as they go in.
- Testing and the certificateWe test insulation, continuity and RCD or RCBO operation, restore the supply and walk the property so lights and sockets come back as expected. You receive the certificate before we leave.

“Ten years on Colchester housing stock and I have seen most of it: terraces where the lighting circuit has been extended once too often, boards fitted before RCDs were standard, new builds with sockets nowhere near the kitchen. I check the earthing, the bonding and whether the supply will carry another load before I price anything, because the age of a house settles nothing on its own.”

How much does fuse board replacement cost?
Consumer unit replacement starts at £450. A larger board, a metal enclosure or awkward access can take the labour above that starting figure. We confirm the written price before we isolate the supply.
How long is the power off?
A straightforward domestic swap is usually done in one visit. The supply stays off from isolation until the new consumer unit is tested and switched back on.
Do I need a certificate for a new consumer unit?
Yes. Replacing a fuse board is notifiable electrical work. Applicable paperwork is issued and notified through NAPIT so the record sits with the local authority.
Can you change a fuse board in a rented house?
Yes. Landlords book this after an EICR or when tenants report tripping fuses. Use the published phone or online booking; appointment scope is confirmed and applicable paperwork follows the work, including access arranged with the occupant.
Will you replace a board that still has fuse wire?
Yes. Rewirable fuse boards are a common reason for the job. We fit a modern consumer unit and move the existing circuits onto breakers with RCD or RCBO protection.
