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.
