Fuse Box / Consumer Unit Replacement in Barnet & North London
An old or damaged fuse box is one of the biggest safety risks in a home. MONOCO Electrical replaces consumer units across Barnet, North London and Greater London — upgrading you to a modern 18th Edition unit with individual RCBOs on every circuit for better protection and fewer nuisance trips.
Signs your fuse box needs replacing
Frequent tripping, a fuse box with rewireable fuses, no RCD protection, visible scorching or corrosion, a burning plastic smell, or a unit older than 15 years all indicate a replacement is due. Insurance surveys, mortgage reports and EICRs regularly flag these units as unsatisfactory (C2 or C3 codes).
What a modern consumer unit gives you
New 18th Edition units use RCBOs — one device per circuit — which means a fault on the fridge circuit no longer takes out the lights. All units are made from metal (not plastic) as required by current regulations, and include surge protection where appropriate.
Fitting and certification
Most consumer unit replacements are completed in a single day. We isolate the incoming supply safely, install the new unit, transfer and label every circuit, then carry out full insulation resistance, earth loop and RCD tests before issuing your Electrical Installation Certificate. Work is notified to Building Control under Part P.
