The Home of PEN Fault Protection

matt:e was founded in 2013 by a team of engineers and electricians who shared a common goal: to design and develop innovative, energy-saving electrical solutions that raise industry standards.

Today, with a rapidly expanding product portfolio, matt:e remains committed to delivering robust, compliant, and easy-to-install products that save time, reduce installation costs, and, above all, prioritise safety for both installers and end users.

We proudly support British manufacturing. Wherever possible, we source components and materials from UK suppliers, maintaining high quality while strengthening local industry.

Our patented* O-PEN® technology, incorporated across key product ranges including Guardian, provides fully compliant protection against the dangers associated with an open PEN conductor on three-phase TN-C-S (PME) supplies. This ensures enhanced safety for both single-phase and three-phase loads, aligned with the latest IET:01 guidance.

For installations with a single-phase TN-C-S (PME) supply, we offer our UK-manufactured SP and IP EVCP connection centres, engineered to deliver dependable, compliant protection for EV charging applications.
