What happens on the day
Replacing a fuse board is a systematic process requiring several hours of planned work, during which the mains power is switched off while safety is prioritised.
- Pre-replacement testingBefore disconnecting the existing equipment, tests are run across every circuit to identify hidden insulation breakdown or existing earth faults. Catching these issues early prevents newly installed sensitive safety devices from tripping immediately upon re-energising.
- Board installation and labellingThe old unit is removed and the new metal enclosure is mounted securely. Circuit conductors are neatly routed, connected into matched protective devices, and clearly labelled so each switch corresponds directly to its room or appliance.
- Final testing and walk-throughOnce the board is wired, live testing checks trip times, earthing paths and loop impedance. The mains supply is restored, circuit operation is confirmed, and the working layout is demonstrated before departure.

WhatsAppHow long will the power be off during the replacement?
A standard consumer unit replacement generally takes between half a day and a full day. The mains electrical supply must remain isolated for the majority of this period while the old board is removed and the new unit is assembled and wired.
Can my existing cables be connected to a new consumer unit?
In most cases, existing cables connect directly into modern breakers. Because new boards feature sensitive trip devices, each circuit is tested before connection to ensure there are no pre-existing neutral-to-earth faults that could cause persistent nuisance tripping.
What is the difference between a fuse board and a consumer unit?
A traditional fuse board contains rewirable wire fuses or plug-in cartridges that melt when overloaded. A consumer unit uses modern miniature circuit breakers and residual current devices that switch off automatically in milliseconds to protect human life against electric shocks.
Is a fuse board upgrade covered by building regulations?
Yes. Swapping a consumer unit is notifiable electrical work under Part P of the Building Regulations. You will receive an Electrical Installation Certificate and official notification documentation once the testing is verified.
What happens if a circuit fault is discovered during testing?
If testing reveals an underlying issue such as damaged cable insulation or poor continuity on a ring circuit, the cause will be explained along with a clear price to repair the fault before that circuit is safely energised on the new board.
