Over 40 years of Excellence

E Preston has been a specialist distributor of electrical and electronic components since 1980, offering thousands of products to meet a wide variety of needs and applications.

But we do more than simply sell components – we have built a reputation as a company who does business the traditional and honest way. Paying attention to the simple things – like phoning people back when we say we will – has kept our customers coming back for over four decades.

Our staff are experts in their fields, we maintain appropriate stock levels, and all of our processes are fully computerised to ensure a smooth operation.

We also understand that business is carried out between people, not companies. We do the hard work to maintain relationships with our suppliers as well as our customers. That way everybody in every part of the supply chain is satisfied – from the manufacturer to the end customer.
