Credentials
Every reference below is a number you can check with the body that issued it. We list the issuing body, the scope and the expiry date rather than a wall of logos, because a logo proves nothing and a certificate number does. Where a record sits on a members-only platform rather than a public registry, we say so and share it on request.

We hold our own marks in both our home market and the US. We register them for the same reason you register yours — so nobody else can. That is also why your artwork, patterns and tech packs stay yours: we do not resell a customer’s design, and we do not list it under a mark of our own.
