Fuse Board Upgrades

Modern protection against shocks and fire

Your consumer unit (fuse board) is the heart of your electrical system. Old wooden-backed or plastic boards with rewireable fuses offer little protection against electric shock or fire. A modern metal-clad board with individual RCBO protection isolates faults instantly and keeps the rest of your home powered.

A new consumer unit is notifiable work — you receive an Electrical Installation Certificate and Building Control sign-off.

What’s Included

Everything covered, done to standard

RCBO Boards

Each circuit gets its own RCBO so a single fault never plunges the whole house into darkness.

Surge Protection

Type 2 SPDs guard sensitive electronics — boilers, TVs, computers — against power-line surges.

Pre-Upgrade Testing

We test existing circuits first so we can flag any issues before energising the new board.

Tidy Installation

Clearly labelled circuits, neat cable management and a printed schedule for your records.

FAQs

Fuse Board Upgrades — your questions answered

Why should I upgrade my fuse board?

Older boards with rewireable fuses or a single RCD offer limited protection. A modern metal-clad consumer unit with individual RCBOs isolates faults instantly, protects against electric shock and fire, and means a single fault won’t cut power to the whole house. It’s often the single biggest safety improvement you can make.

How long does a fuse board upgrade take?

Most consumer unit replacements are completed in a single day. We test the existing circuits first, fit the new board, label everything clearly and issue your certificate before we leave.

Faultless EV charger install
Booked Brightwell to fit a 7kW charger and they sorted the whole grant claim for me. Tidy, on time and explained everything. The app setup was done before they left. Couldn’t fault them.

Rewired our 1930s semi beautifully
Full rewire on a lived-in house. They protected the carpets, cleaned up every day and the making-good was spot on. Certificate came through two days later. Genuinely premium service.

LED downlights throughout
Had the whole ground floor fitted with downlights and some extra sockets. The finish is immaculate — you’d never know walls had been chased. Polite, careful and great value.
