Consumer Unit Upgrades

An RCBO protects each circuit individually, combining overload, short-circuit, and residual current protection in one device. This means a fault on one circuit is less likely to turn off power to the whole property. We can advise whether an RCBO consumer unit is the best option for your home.

Surge protection helps protect your electrical equipment from voltage spikes, which can damage appliances and sensitive electronics. A Surge Protection Device, or SPD, is often recommended as part of a modern consumer unit upgrade. Contact us and we can explain whether surge protection is suitable for your property.

A typical consumer unit replacement can often be completed within a day, depending on the condition of your existing wiring and the amount of testing required. If any faults are found, these may need to be repaired before the new unit can be safely connected. Get in touch and we can give you a more accurate timescale.

Sometimes, but the wiring must be tested first. If the existing wiring is safe and suitable, a new consumer unit may be fitted. If faults are found, they will need to be repaired before the upgrade can be completed safely. Book an inspection with us and we can check your wiring before recommending the next step.

Yes. A consumer unit replacement should be tested and certified once the work is complete. We provide the relevant electrical certification for our work, so you have clear proof that your installation has been checked and completed properly.

In England and Wales, replacing a consumer unit is generally notifiable under Part P of the Building Regulations. Using a registered electrician helps make the process straightforward, as the work can usually be notified through the correct scheme. Contact us and we can explain what is required for your property.

The cost of a consumer unit upgrade depends on the number of circuits, the type of consumer unit, whether surge protection or RCBOs are required, and whether any faults are found during testing. Get in touch for a quote and we can give you a clear price based on your installation.

Many people use the terms interchangeably, but “fuse box” often refers to an older unit with fuses, while “consumer unit” usually refers to a modern board with protective devices such as MCBs, RCDs, RCBOs, and surge protection. If you are not sure what you have, send us a photo or arrange a visit and we can advise.

Landlords must ensure rental properties are electrically safe and have the required inspections. An old consumer unit does not always mean automatic replacement, but if it is unsafe or lacks suitable protection, remedial work may be needed.
