Modern consumer units offer far greater protection than older fuse boards. If your Dulwich property still has rewireable fuses or no RCD protection, this 2025 guide explains why upgrading is essential.
What’s the Difference Between a Fuse Board and a Consumer Unit?
Fuse boards contain fuses that melt when overloaded, while consumer units use resettable circuit breakers (MCBs) and life-saving RCDs. The upgrade improves safety, efficiency, and compliance with BS 7671 standards.
Signs You Need a Fuse Board Upgrade
- Rewireable or cartridge fuses instead of circuit breakers.
- No RCD protection on sockets or outdoor circuits.
- Buzzing or burning smells from the fuse board area.
- Frequent tripping or outdated labels.
Benefits of a 2025 Consumer Unit Upgrade
- Improved RCD protection against electric shock.
- Enhanced fire safety from arc fault and surge protection devices.
- Clear labelling and easier fault isolation.
- Compliance with landlord and EICR regulations.
