Solving the problems that are difficult to see, but too important to overlook.
Since 1989, Tolbest has developed and supplied specialist dyes and powders for applications across a number of industries where a clear, visible result matters.
From tracing hidden water routes and revealing rodent activity to marking condemned animal by-products, managing algae and weed growth and checking spray coverage, our products help you see what is happening and where action may be needed.

Specialist knowledge since 1989

From our base in the Northwest, Tolbest began by specialising in tracing dyes, drain-testing equipment and dyes used to mark waste food. During its early years, our range expanded to include rodent tracking dusts and other specialist products, building the foundations of the business we are today.
From public-sector utilities and global distributors to food manufacturers, pest-control specialists and award-winning estates, our products are used wherever a clear, reliable result is needed.
What connects these very different applications is the specialist knowledge behind them and the confidence that Tolbest products will perform consistently. It’s an approach that has helped us build customer relationships spanning decades, with some continuing for 28 years…and counting.
Different applications. The same specialist approach.
Tolbest supplies distributors, equipment providers, public-sector and regulated organisations, field operators and businesses purchasing products for supply under their own brand. Each may buy or use our products differently, but all depend on consistent performance, practical support and clear information.
Specialist manufacturing
Tolbest’s expertise lies in specialist products developed for defined applications, rather than general-purpose products. All of our products are formulated, manufactured, mixed, blended, filled and packed at our own site in Warrington, where they are produced and supplied under the Tolbest brand. We also have the capability to manufacture and supply products on a white-label or contract-manufacturing basis.
Part of a wider specialist group
Tolbest is part of PHD Industrial Holdings’ Speciality Chemicals Division, alongside other established UK manufacturing businesses. Being part of a wider specialist group supports the next stage of our development, bringing together complementary manufacturing expertise and capabilities while retaining the specialist knowledge and practical focus we have built since 1989.
