Consumer Unit Upgrades
Modern protection for today's electrical demands.

Why upgrade
Older fuse boards weren't built for modern homes.
EV chargers, induction hobs, heat pumps & dozens of always-on devices place demands on an installation that older fuse boards were never designed to meet. A modern consumer unit brings the whole home up to current standards.
Modern protection
Layered safety, quietly built in.
01
MCB
Miniature Circuit Breakers protect each circuit from overload & short-circuit faults, resetting cleanly without replacement.
02
RCD
Residual Current Devices detect earth leakage & disconnect the supply in milliseconds to protect against electric shock.
03
RCBO
One breaker per circuit combining MCB & RCD protection - a fault trips only the affected circuit, never the whole house.
04
AFDD
Arc-Fault Detection Devices identify damaged cables & loose terminations before they overheat & ignite.
05
Surge
Surge protection guards sensitive electronics from lightning strikes & grid-side voltage spikes.
Compare

Let's talk
Upgrade the heart of your electrical installation.
A consumer unit upgrade is usually completed in a single day & includes full testing, certification & building control notification.
