Your fuse box (also known as a consumer unit) is the heart of your home’s electrical system—and one of the most important parts of keeping your property safe, legal, and insurable.
But is yours compliant with current UK electrical standards?
If you live in South West London—in areas like Wimbledon, Fulham, or Clapham—chances are your home may still have an outdated fuse box that needs attention.
In this guide, the certified electricians at Lumiel explain:
The consumer unit is where all your circuits are controlled and protected. It distributes power throughout your home and automatically cuts electricity when there's a fault.
A modern consumer unit includes:
If your fuse box lacks these, it may not meet current standards.
The 18th Edition of the IET Wiring Regulations (BS 7671) is the latest version that all electrical systems must follow. It includes requirements such as:
✅ RCD protection on most circuits
✅ Proper earthing and bonding
✅ Use of fire-resistant consumer units (metal enclosures)
✅ Correct labelling and circuit segregation
✅ Surge protection (mandatory in most homes since 2022)
All new or altered electrical installations must comply with these rules.
A homeowner in Fulham SW6 was installing a new kitchen and EV charger. We found a 1990s plastic fuse board with no RCD protection.
We replaced it with a modern metal consumer unit with RCBOs and surge protection in just one day.
✅ Fully compliant, certified, and future-ready.
Lumiel includes this inspection in all rewire assessments and EV charger installations.
