Consumer Unit Upgrades Cardiff
Replace dangerous wooden-backed or outdated fuse boxes with non-combustible metal consumer units featuring RCBO breakers and Surge Protection Devices (SPD).
The Heart of Your Property's Electrical Protection
Your consumer unit (or fuse board) is the central safety hub of your home. Outdated boards with rewireable copper fuses or early plastic casing provide little to no protection against electric shocks or electrical fires.
Under current 18th Edition wiring standards, domestic boards must be non-combustible steel and incorporate RCD/RCBO protection that trips in milliseconds if an earth fault occurs. Surge Protection Devices (SPDs) are also installed to shield sensitive electronics, TVs, and appliances from mains spikes.
Every consumer unit upgrade completed by DW Electrical Specialists includes full pre-installation circuit checks, neat installation, and an Electrical Installation Certificate (EIC).
Benefits of Modernizing Your Consumer Unit
Fire-rated steel construction contains internal arcing and heat in the unlikely event of a fault.
If one circuit trips (e.g. a kettle), only that specific breaker trips — the rest of your house remains powered.
Protects smart TVs, laptops, heat pumps, and home office tech from lightning and utility surges.
Every existing circuit in your home is measured and certified, ensuring overall installation safety.
