Our B Corp Certification
Three years after becoming the highest-scoring B Corp in the UK (& highest fashion brand globally), we’ve just recertified with an even higher score of 168.8! We are so proud to share this major milestone in our ongoing commitment to responsible business practices.
After more than a year of hard work, Y.O.U Underwear originally certified as a B Corp in December 2021, with a score of 160.5. We wanted to show that purpose, people and planet mean more to us than profit. Giving back and sustainability are at the heart of what we do, and we wanted to have that commitment verified by something as respected as a B Corp Certification.
Recertifying three years later was no easier, particularly as a more established business, with an expanded product offering, shop in Oxford, and a wider range of suppliers and manufacturing partners. That makes our improved score even more meaningful, as we continue to show that business - & fashion - can be a force for good.
Our B Corp Score
When originally certifying in November 2021, our score was 160.5, proudly making us the highest scoring company in the UK (& top-scoring fashion brand globally) at the time.
We definitely felt the pressure when it came to recertification 3 years later, part of the commitment to continuous improvement integral to the movement. However we were thrilled to increase our score to 168.8 in June 2025, showing that we're not standing still despite the increasingly challenging environment we're working in.
The B Corp assessment evaluates your overall social and environmental performance across five key areas: governance, workers, community, environment, and customers. This holistic evaluation is one of its strengths and we're proud to have scored highly across each of the 5 key areas.
What is a B Corp?
Certified B Corporations are companies verified to meet the highest standards of social and environmental performance, transparency, and accountability.
The minimum score required to become a B Corp is 80 points on the B Impact Assessment (BIA). The BIA evaluates a company's overall social and environmental performance across five key areas: governance, workers, community, environment, and customers. The median score for ordinary businesses who complete the assessment is currently 50.9.
We're now part of a community of 9,948 businesses globally who have certified as B Corps. The B Corp community in the UK is comprised of over 2500 companies!
We're One of The Best for the World™ B Corps!
To be Best For The World, B Corps must have scores in the top 5% of one or more of the five impact areas assessed towards the certification. We achieved Best for the World in two areas - community and environment.
It's just the start
Whilst we are, obviously, thrilled with our score and certification - we know our work isn't done. We promise to strive to make our underwear, packaging and business more responsible and ethical - year on year. We have a lot of exciting ideas and projects in the works and we hope that you'll support us on our sustainable journey.
Here's to making fashion more accessible, ethical and planet-friendly!
