Thornton & Ross Reception

A company you can rely on

Founded in 1922, Thornton & Ross Ltd is the largest independent OTC pharmaceutical manufacturer in the UK and exports to over 80 countries worldwide. We continue to grow our business every year in the UK and International markets by innovation and acquisition.

From a base in Huddersfield, West Yorkshire, Thornton & Ross develop, manufacture and supply a wide and growing range of branded OTC medicines and other pharmaceutical, healthcare and hygiene products.

Our product portfolio encompasses a large number of well-known OTC brands such as Covonia®, Hedrin®, Care®, Radian B® and Setlers®, as well as the UK's leading disinfectant Zoflora®.

As a privately owned business competing with multi-national pharmaceutical manufacturers, we are able to combine the highest professional standards with the traditional levels of care that would be expected from a family concern.

Our approach is to combine good, responsive customer service and quality products, in a working environment that encourages innovation.
