About Surge Protection Devices Ltd

Founded in 2006, we have spent the last 20 years helping electrical wholesalers, contractors, consultants and engineers protect electrical installations from the damaging effects of lightning and transient overvoltages.

At Surge Protection Devices Ltd, we believe that great technical solutions start with great people. Whilst our products protect some of the UK’s most critical installations, including commercial, industrial and public sector projects, we remain a close-knit, family-run business at heart. Our size allows us to do something many larger manufacturers struggle to achieve – provide genuine technical support from people who truly care about getting the right solution for every customer.

Our reputation has been built on honesty, integrity and technical expertise. We don’t believe in simply selling products; we believe in helping our customers understand surge protection and ensuring devices are specified and installed correctly.

Over the years, we have become recognised throughout the electrical industry for our educational approach. Through CPD seminars, contractor training sessions, technical guidance and industry involvement, we are committed to raising standards and improving knowledge across the sector.

Today, our products are protecting electrical installations across the UK and beyond, but our philosophy remains unchanged: provide outstanding technical advice, exceptional customer service and reliable surge protection solutions that customers can trust.

Whether you’re a contractor looking for installation advice, a wholesaler seeking expert support, or a consultant working on a complex specification, our team is here to help.

Because protecting electrical installations is what we do.
