WT Knowles

W T Knowles & Sons Limited has been manufacturing and supplying an extensive range of clay chimney pots and cowls since 1906. Their West Yorkshire factory is still owned and managed by the 4th generation family.

Based in Elland in West Yorkshire, the Company remains one of the few UK clay pot manufacturers supplying an unrivalled and comprehensive range of clay chimney pots to the UK housing market through building and roofing merchants nationwide.

Despite being in business for over 100 years, many of the traditional manufacturing processes have been maintained, including salt-glazing. W T Knowles remains the only manufacturer of salt glazed chimney pots in the UK and also has the widest selection of inserts for existing chimneys and redundant flues, available in both glazed and unglazed finish.

A wide range of chimney pots, inserts and gas flue terminals have been independently type tested and certified by BSI to BS EN 13502:2002, are CE marked and comply with the Construction Products Regulations. Chimney pots and inserts are available for Solid Fuels, Gas, Multi-Fuel and Redundant Flues.

With over 160 different products in the chimney pot and accessories range, W T Knowles has one of the most extensive product listings in the UK. Their focus is on producing high quality products supported by relatively short delivery schedules.

Their flexibility enables them to provide our customers with a range of standard and more specialised products, frequently from stock. Many of their chimney pot designs have been tailored to suit customer needs. Not only are different styles and designs available but also different colours too. The most popular colour of the chimney pots is terracotta red but the unique salt glazed finish complements the striking finish of buff.
