Want to become a CALM verified supplier?
Not only will you gain access to all the fantastic benefits of our CALM Verified Supplier Certification but you’ll also gain a place on our Preferred Supplier list.
Our aim is to provide an independent verification of your business which you can use in your marketing but also create a powerful list of Preferred Suppliers so we can refer you to customers as they need you.
You can find the questions you will need to answer during the application here (sorry about the tiny font, who know’s what’s happening with the settings at the moment) and we follow this up with a company credit check, review of your standard terms of business & insurances.
You can find out more about our CALM Verified Supplier Certification & our CALM Supplier Directory if you need more information.
We’re looking for suppliers who are open, transparent and supportive of their customers. Check out our Supplier Code of Conduct.
