What happens on the day

A consumer unit installation generally requires between half a day and a full day to complete, depending on the number of circuits. The electricity supply remains switched off during the replacement work while safety procedures are followed.

  • Pre-installation circuit testingBefore removing the old enclosure, every circuit undergoes dead testing to check insulation resistance and continuity. Identifying preexisting wiring faults beforehand prevents newly installed sensitive trip switches from disconnecting immediately when powered up.
  • Board removal and new enclosure fittingThe old fuse box is safely disconnected and removed from the wall. We mount a sturdy, non-combustible metal consumer unit equipped with dual RCD protection or individual RCBOs and integral surge protection devices.
  • Wiring connection and circuit labellingAll circuit conductors are neatly dressed, terminated securely into their respective breakers, and clearly labelled so you can identify which breaker controls each room, socket ring, or fixed appliance.
  • Live testing and handoverOnce the power is restored, we run live diagnostic checks across all switches and RCD mechanisms. You receive a full walkthrough explaining the trip switches and the integral surge protection device.

Frequently asked questions about fuse board replacements

Still have a question?

How long will the electricity be turned off during the upgrade?

The power is typically switched off for the majority of the installation, which generally lasts between half a day and a full day. We isolate the incoming supply to safely disconnect the old unit, mount the new enclosure, and connect each circuit before carrying out live testing.

Will my existing cabling work with a modern consumer unit?

In most cases, existing wiring connects successfully to a new board. We perform testing across every circuit before wiring it into the new unit. If an underlying cable defect or insulation issue is uncovered that would cause modern RCDs to trip, we discuss the necessary repair options and costs before proceeding.

What is the difference between an old fuse box and a modern consumer unit?

An older fuse box uses replaceable fuse wire or early cartridge fuses that only guard against circuit overloads and short circuits. A modern consumer unit houses sensitive RCDs or RCBOs that cut power within milliseconds of detecting an earth leakage current, dramatically lowering the risk of severe electric shocks.

Is a consumer unit replacement notifiable under building regulations?

Yes. Replacing a consumer unit is notifiable domestic electrical work under Part P of the Building Regulations. We certify and register the installation, and you receive an official Electrical Installation Certificate for your records.

Do I need to replace my fuse board before getting an EV charger installed?

Adding a dedicated high-draw circuit like an electric vehicle charger often requires spare capacity, compatible surge protection, and specific RCD types that older boards lack. If your current unit is full or outdated, upgrading the consumer unit first ensures your new charging point operates safely and legally.
