Mitre - Suppliers of luxury linen to the hospitality industry since 1946

Cala Sustain has advised and supported Mitre Linen in meeting rigorous sustainability requirements required by the Royal Warrant Household Association.

A complex range of responsible business topics are reviewed when applying for a new or renewing an existing Royal Warrant. These include ethical, environmental and social considerations during sourcing, manufacturing, assembly, distribution and use of products.

Mitre achieved successful renewal of the Royal Warrant in 2019.

Cala Sustain is proud to have successfully guided Mitre during its Royal Warrant application and to have supported Mitre in successfully gaining ISO’s 14001, 9001, 45001 and 50001.


I just wanted to thank you for all the support you gave us with the renewal of our Royal Warrant.

We all breathed a big sigh of relief when we found out that we had been successful, and we couldn’t have done it without you!

Thanks again
