Due to the situation with the coronavirus, we are currently operating with a reduced workforce.

We have partially resumed operations to support our distributor and direct partners, who supply essential products and services to end users in this unprecedented fight against COVID-19.

We are working hard to respond to your orders and queries and will get back to you as soon as possible.

Waiting times may be longer at the moment so please feel free to contact us at www.starrett.co.uk/contact
