Caswell FRD is a division of C. Caswell Engineering Services Limited , a privately-owned Ventilation and Air-Conditioning contracting business established over 50 years ago.
As our name suggests, we are Fire Resisting Ductwork specialists and manufacture CASWELL FIRESAFE® systems under licence from Firesafe Fire Rated Ductwork Limited, winners of a Queen’s Award for Enterprise in 2019.

CASWELL FIRESAFE® was developed in the UK in 2003 and is now recognised as a leading international brand. Specified worldwide, CASWELL FIRESAFE® systems have been installed within countless prestigious and iconic building projects across the globe over the past 17 years.

C. Caswell Engineering Services Limited, known simply as ‘Caswell’ throughout the industry, are part of C. Caswell Holdings Limited, which also incorporates Firesafe Fire Rated Ductwork Limited and Konvekta Limited. The Caswell business was formed in the UK in 1969 by Colin Coxen. Ownership and management then passed to the next generation – through siblings Richard, Charles, Carolyn & Robert – and has been run as a successful family business from our manufacturing base in Lancashire ever since.
