till using an old-style fuse box with ceramic fuses? If so, your home’s electrical safety may be at risk. A modern consumer unit upgrade offers better protection, improved performance, and full compliance with current regulations. Let a qualified Electrician in London handle your fuse box upgrade with precision and safety.
What Is a Fuse Box (Consumer Unit)?
A consumer unit, commonly called a fuse box, distributes electricity throughout your home. It controls and protects each circuit. Older boxes often lack Residual Current Devices (RCDs) or Miniature Circuit Breakers (MCBs)—both crucial for safety.
Modern units detect faults fast and shut down circuits to prevent electrocution or fire.
Signs You Need a Fuse Box Upgrade
Consider an upgrade if:
- Your current box has rewireable fuses
- Lights flicker or breakers trip frequently
- You’ve added high-load appliances like EV chargers or electric ovens
- The fuse box smells of burning
- There’s no RCD protection for circuits
If your system is over 25 years old, it's time to update.
Benefits of a New Consumer Unit
Upgrading offers many advantages:
- Improved Safety: RCDs protect against electric shocks
- More Circuits: Supports modern households and tech
- Clear Labelling: Easy to identify and isolate issues
- Compliance: Meets current BS 7671 wiring standards
- Insurance Validity: Some insurers require modern systems
It’s one of the best electrical investments you can make.
How Long Does the Upgrade Take?
A full replacement typically takes 4–8 hours. Your Electrician in London will:
- Safely disconnect power
- Remove the old fuse box
- Install a new 17th/18th edition consumer unit
- Test all circuits for faults
- Provide a certificate of compliance
Minimal disruption, maximum peace of mind.
