Sledge and SWM Partners Bolster Purpose-Driven Model with B Corp Certification

The agencies achieved a B Impact Assessment (BIA) score of 130, far exceeding the minimum 80 points required to gain certification

8 OCTOBER 2026, LONDON UK – Proudly employee owned and purpose-led event agencies Sledge and SWM Partners today announce they have become a Certified B Corporation™ (B Corp).

Following a rigorous process that involved an evidence-based analysis of the Group’s entire operations, covering impact areas related to practices around governance, workers, community, the environment and customers, it received a B Impact Assessment (BIA) score of 130. This sits well above the minimum 80 points required to attain B Corp status, and the 50.9 median score for ordinary businesses.

The score reflects the strength of the company’s approach across both its day-to-day operations and purpose-driven business model, whereby it embeds positive social and environmental impact into the way it operates and the value it creates through its core business.

Verified by B Lab™, the not-for-profit behind the B Corp movement, the accomplishment demonstrates the Group meets high standards of social and environmental performance, transparency, and accountability across its operations and projects, alongside a commitment to goals beyond shareholder value.

The achievement aligns with employees’ values, and marks a collective and passionate effort by all team members to guide the company and the clients it supports towards a positive future, one where purpose is placed alongside profits, and sustainability is firmly centre stage.

Sarah Yeats, who has been promoted to Group Managing Director to help take the business to the next level as it works towards its sustainability vision, says: “While we’ve been operating in line with B Corp, as well as several other industry-leading standards since the implementation of our Sustainability Management System (SMS) in 2024, becoming B Corp certified officialises our commitment to putting purpose alongside profits, and sustainability centre stage.

“As such, it’s very much business as usual at Sledge and SWM Partners, as we continue our focus on embedding sustainability into our entire business model, our culture and our events. The Group’s B Corp status is an important milestone on this journey, and will only keep us even more accountable as we ensure compliance with its best practice standards and annual reporting requirements.”

The progress doesn’t end there, with the Group currently on the journey towards obtaining the International Standard for Event Sustainability (ISO 20121) and the International Standard for Environmental Management (ISO 14001).
