If your home still runs on an old-fashioned fuse box, it may be time to consider an upgrade. A modern consumer unit offers far better protection against electrical shocks, overloads, and fire risks. At NICEIC Electricians, we specialise in safe and certified fuse box replacements across London, with a particular focus on residential properties in Barnet and nearby areas.
Many homeowners don’t realise their fuse box is outdated until something goes wrong. Whether you’re renovating, renting out, or just want peace of mind, a consumer unit replacement is a wise investment in your home’s electrical safety.
Why Replace an Old Fuse Box?
Old fuse boxes often rely on rewireable fuses. These are no longer considered safe by modern standards. Here’s why a replacement is necessary:
-
Lack of RCD protection – crucial for detecting earth leakage and preventing fatal shocks.
-
No overload protection – risk of fire from overheated circuits.
-
Hard to maintain – replacing fuse wire is time-consuming and risky.
-
Non-compliance with BS 7671 regulations – especially important if you’re renting or selling.
At NICEIC Electricians, we replace outdated systems with 17th or 18th Edition compliant consumer units, fitted with RCDs and MCBs to modern safety standards.
What’s in a Modern Consumer Unit?
A typical replacement consumer unit installed by NICEIC Electricians includes:
-
Main Switch: Isolates electricity for maintenance or emergencies.
-
RCDs (Residual Current Devices): Cut off power if an imbalance is detected.
-
MCBs (Miniature Circuit Breakers): Trip automatically during overload or short circuit.
-
RCBOs (optional): Combine MCB and RCD protection in one device for individual circuits.
-
Busbar & Neutral/Earth terminals: Organise safe electrical distribution.
All components are arranged for optimal accessibility and safety. We only use materials approved under UK standards.
