Consumer Units for UK Domestic & Commercial Installations
Consumer units (also known as fuse boards or distribution boards) form the central point of every electrical installation. They safely distribute power across lighting, socket and appliance circuits while housing the necessary protective devices under the 18th Edition Wiring Regulations.
Our collection includes consumer units in multiple sizes, enclosure types and protection layouts - from compact domestic boards to higher-capacity commercial formats.
Quick overview: Modern UK installations require metal consumer units with appropriate RCD, RCBO and surge protection provisions. Selecting the correct board size ensures compliance and future expansion capacity.

Understanding Modern Consumer Units
Under current UK regulations, most new and upgraded installations require metal consumer units that provide fire containment and support modern protective devices such as RCBOs and surge protection.
Protection Layout Options
- Main switch boards – flexible configuration
- Split load RCD units – grouped circuit protection
- RCBO-ready boards – individual circuit protection
- SPD-compatible units – surge protection integration
Choosing the Right Size
Consumer unit size depends on the number of circuits required and future expansion. Modern homes often need additional ways for EV chargers, heat pumps, outbuildings and kitchen upgrades.
