Holt Lloyd
Problem Solved

Holt Lloyd or “Holts” has been solving car problems since 1919, and for over 100 years, we have been working hard to keep your car on the road.

Using our years of expertise, Holts prides itself on developing products to eliminate those clunks, leaks and squeaks that develop over time, with as little fuss as possible.

With ownership of consumer brands such as Redex, Simoniz, Prestone, and Holts, we manufacture and distribute some of the most well-known and trusted brands in the automotive industry today.

Since Douglas Holt first started selling car parts in 1919, the company has been committed to helping drivers to maintain their cars and keep driving. As a British company who develop, test and manufacture products right here in the UK to export across the globe, we’re proud of our heritage and place in the automotive industry.

Over the years we’ve forged links with mechanics and professionals as well as consumers, constantly innovating to ensure our products meet the needs of modern cars. We’ve also built up a family of 4 brands – Holts, Prestone, Simoniz and Redex – which offer high quality products across fuel additives, car care, maintenance and repairs.

With this family now in place, we decided the time had come to update our logo to reflect this history and where we are now.

The new design lets us display our proud British heritage, and lets you know that we’ve been here since 1919 and we’re still driving forward – always pushing to innovate, looking for new ways to help you look after your car and meeting gaps in the market, whether it’s in the UK or in one of the many global locations we operate in.


At Holt Lloyd, we’re proud that our products are developed, tested and manufactured here in the UK. We have a lab in Manchester where our highly skilled and experienced Research and Development team make sure each of our products perform for you on the road.

Phil Carruthers, Research & Development Manager

As our Research and Development Manager, Phil oversees all operations at the lab. Having been with Holts for 10 years, it’s safe to say that whatever Phil doesn’t know about Holts products, isn’t worth knowing!

Phil is also our chief ‘RedExpert’ – looking after the Redex product range.

“I enjoy working in R&D due to the variety of products we work on, I get to combine my interest in cars with my job and each day is different from the last.

Not to mention that it’s always good to see something you developed on a retailer’s shelf.”
