Non-Combustible Enclosure
A metal consumer unit, built to contain a fault rather than add to it.
Consumer Unit Replacement
Consumer Unit Upgrades in High Wycombe & Beaconsfield
Is it time to bring your electrics up to current safety standards? A modern consumer unit (fuse board) has a non-combustible enclosure, surge protection as standard and an RCBO on every circuit, so one faulty circuit no longer cuts the power to the whole house.
Consumer Unit (Fuse Board) Replacements
Bring Your Fuse Board Up to Current Standards
Many of the homes we visit still have old rewirable fuse boards. They were fine in their day, but protection has moved on a long way since then. A new consumer unit gives you:
- A non-combustible metal enclosure
- RCBO protection (30mA) on every circuit, so a fault only switches off the circuit affected
- Surge protection as standard
- A heat-activated fire suppression device fitted inside the unit as standard
- Type A RCD protection, suitable for EV chargers
- Clearly labelled circuits
- The fixed wiring throughout your property fully tested
What You Get
What's Included With a New Consumer Unit
Every consumer unit we fit is built around current safety standards, with protection on each individual circuit and the whole installation tested before we leave.
RCBO on Every Circuit
Each circuit has its own 30mA protection, so a fault switches off that circuit only, not half the house.
Surge Protection
Fitted as standard to help protect your electronics and appliances from voltage spikes.
EV Charger Ready
Type A RCD protection, suitable for EV chargers.
Built-In Fire Suppression
Every unit we install includes a heat-activated aerosol fire suppression device as standard, for extra protection inside the enclosure.
Tested & Certified
Circuits are clearly labelled, the fixed wiring throughout your property is tested, building control is notified and you receive your certificate.

Is It Time?
Signs It May Be Time to Upgrade
You don't have to wait for something to go wrong. These are the most common reasons our customers decide to replace their consumer unit.
1. An Old Fuse Board
Rewirable or cartridge fuses, often with no RCD protection at all.
2. Nuisance Tripping
One fault cutting the power to several circuits at once, because they all share a single RCD.
3. New Demands on Your Electrics
Adding an EV charger, an extension or new circuits, when the existing board has no spare capacity or suitable protection.
