What’s the difference between a fusebox and a consumer unit?

Ultimately, a fusebox and consumer unit refer to the same thing. The only difference is how they are wired:

Traditional fuseboxes have rewireable fuses and were used in older homes
Modern consumer units use MCBs (miniature circuit breakers) and RCDs (residual current devices), which offer improved safety and faster fault detection

Can I fit a new consumer unit myself?

No. Replacing a consumer unit is notifiable work under Part P of the Building Regulations and must be carried out by a qualified electrician.

DIY installation is unsafe and illegal unless you're properly certified. A registered electrician will ensure compliance and issue the correct certification.

Do I need Building Regulations approval to change a consumer unit?

Yes. Consumer unit replacement must comply with UK Building Regulations (Part P).

Your consumer unit installer will notify the local authority or self-certify through a competent person scheme and provide certification once the work is complete.

Can you replace a fusebox without rewiring the house?

In many cases, yes, you can replace a fusebox without rewiring the house. That’s provided the existing wiring is safe and passes inspection.

Before installation, the electrician will carry out checks (often an Electrical Installation Condition Report) to ensure the system is suitable for a new unit.

If wiring is outdated or unsafe, updates may be needed.
