What happens on the day
A consumer unit replacement takes between half a day and a full day depending on the number of circuits. Power remains isolated while the old board is removed and the new installation is connected.
- Pre-installation circuit testingBefore touching the old board, each circuit undergoes electrical testing to detect pre-existing wiring faults, crossed neutrals or insulation resistance issues that could trip modern sensitive breakers.
- Board removal and metal enclosure mountingThe outdated fuse box is dismantled and safely removed. A non-combustible metal consumer unit is secured to the wall, complete with modern surge protection and residual current devices.
- Circuit reconnection and identificationEvery existing circuit conductor is terminated into its designated protective breaker, neatly arranged inside the enclosure, and marked clearly on the board directory.
- Final testing and handoverThe entire installation is powered up and tested under live conditions to verify trip speeds and earth continuity, followed by a run-through of the new controls and test buttons.

WhatsAppWhat is the difference between a fuse board and a consumer unit?
A traditional fuse board uses rewireable fuses or early cartridge fuses that blow when overloaded but do not protect against earth leakage. A modern consumer unit contains miniature circuit breakers and residual current devices that trip in milliseconds to prevent shocks and electrical fires.
How long does a consumer unit replacement take?
Most consumer unit upgrades take between half a day and a full day to complete. The electrical supply must be turned off for the majority of this period while the old board is removed, the new unit wired, and each circuit individually tested.
Will my existing property wiring work with a new consumer unit?
In most instances, existing wiring works safely with a new board. We test all circuits prior to final connection to verify there are no hidden faults, crossed neutrals or insulation issues. If a problem is identified, options and costs are explained before repairing it.
Do I get an electrical certificate after the fuse board is replaced?
Yes. Replacing a consumer unit is notifiable work under building regulations. You receive an Electrical Installation Certificate confirming the testing results and compliance of the newly fitted board and all connected circuits.
Does a new consumer unit protect against electrical surges?
Modern consumer units are installed with surge protection devices. These devices safeguard delicate electronics, boilers, computers and home appliances from unexpected voltage spikes originating on the electrical grid.
