Company Overview

Singleton Birch Limited has celebrated more than 200 years since the company was founded. Over these two centuries and more we have established ourselves as the UK’s leading independent lime supplier and have built an exceptional reputation for quality and service.

We have diversified into a number of different sectors; each of our operations is part of the Singleton Birch family and encompasses the same standards of excellence in all we do.

Birch Lime continues to focus on  lime and chalk products. Lime is a natural and traditional material used in environmental control, the production of steel, various chemical processes, waste and water treatment, production of lightweight building materials and  other sectors of the construction industry.

Birch Chemicals is the new name for our subsidiary, Innovo, which supplies high quality products to the global plastics and rubber industry,

Birch Solutions operates in the renewable energy and utilities sector and incorporates our technical services department.

Birch Waste is our waste management division incorporating our non-hazardous landfill and waste treatment processes.

During the early part of the 20th century the majority of the shares in the company were owned by Lionel Martin, who also founded the Aston Martin racing car company. His wife Katherine left most of her shares in trust for the benefit of the NSPCC, RSPCA and Barnados.  The Katherine Martin Charitable Trust remains our largest shareholder today.
