Registered in England and Wales (Company No. 17079497), we are headquartered in Merthyr Tydfil, Wales, and serve electricians, contractors, and trade professionals throughout the United Kingdom.

What We Do

We supply a comprehensive range of electrical components designed for domestic, commercial, and industrial installations. Our product portfolio includes miniature circuit breakers (MCBs), residual current devices (RCDs and RCBOs), consumer units, surge protection devices (SPDs), modular contactors, disconnector switches, and a growing line of intelligent EV charging equipment.

Product ranges are supplied with the technical documentation held for them, and our technical support team can confirm what is available for a specific product. We work closely with our manufacturing partners to ensure consistent quality, competitive pricing, and reliable supply.

Our Mission

Our mission is to make high-quality electrical components accessible and affordable for UK professionals. We believe that safety-critical products should not come with inflated price tags, and that every electrician deserves a supplier who understands the standards they work to.
