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.
