We are proudly B Corp™ Certified!

Thanks to the hard work of our whole team, Celtic & Co. is now a certified B Corporation™, joining a global community of businesses held to the highest standards for people and planet.

With a score of 87.9, everything we do, from our ethical supply chains to how we care for our team, has been independently assessed and verified. We have always believed that quality and conscience go hand in hand. This certification proves it.

We continue to grow our range of recycled fiber styles and champion British Wool across our signature knitwear. From our factory in Newquay, Cornwall, our shearling boots and slippers are built to last, and through Celtic Relived, we help them last even longer with our repair and resole service.

“As leaders of the slow fashion movement from the very beginning with our dedication to high quality, timeless style, it’s great to have our commitment to the planet and our people recognized through this internationally renowned certification. Well done to the whole team for all the hard work they put into achieving this accolade.” - Marta Przybyl, Sustainability Manager

B Corp Explained

B Corp Certification means we've been independently verified against B Lab's rigorous standards for social and environmental impact. The certification recognises our commitment to responsible business practices across our entire operation. It's a legal commitment to do right by people and planet, and to be open about how we're doing it.

Our Score

We scored 87.9 in 2025. Every part of how we work has been independently assessed, from our supply chain to our team. We're proud of that. But it's not a finish line. There's always more to do.

Why B Corp?

Here at Celtic & Co, we've always believed in doing the right thing for people and for the planet. But believing you're doing good isn't the same as proving it. We wanted to go deeper, challenge ourselves, and have the backing of something bigger. That's why we started the B Corp journey.

Getting certified means every thread of what we do, from our supply chain to our team culture, has been independently assessed, verified, and scored. It's helped us build trust with our customers, our partners, and ourselves. Not by measuring against others, but by holding ourselves to higher standards year after year.

Where next?

We're not done. We never will be. B Corp gives us a framework to keep improving, but the drive to do better has always been part of who we are. We'll keep measuring, keep challenging ourselves, and keep you in the loop as we go. Because the natural world deserves nothing less.
