What Is Consumer Unit / Fuse Box Installation?
A consumer unit (commonly called a fuse box) is the central hub of your property's electrical installation. It distributes electricity to all circuits and provides overcurrent and fault protection through MCBs (Miniature Circuit Breakers) and RCDs (Residual Current Devices). A consumer unit installation involves replacing your old fuse box with a modern unit that meets current BS 7671 wiring regulations, providing superior protection against electric shock and fire.

Why You Need Consumer Unit / Fuse Box Installation
Old fuse boxes with rewirable fuses or outdated MCBs do not provide RCD protection, which can detect earth leakage faults in as little as 30 milliseconds and disconnect the supply — potentially saving lives. If your EICR identifies your consumer unit as non-compliant, replacement is typically required. Modern consumer units also provide better circuit segregation and surge protection.
Building Regulations
Consumer unit replacement is notifiable work under Part P of the Building Regulations. Our engineers are registered to self-certify this work.
EICR Compliance
If your EICR identifies an outdated fuse box as a C2 observation, a consumer unit upgrade is typically required to achieve a satisfactory result.
Who Needs Consumer Unit / Fuse Box Installation?
