Membership and engagement

Another year of sustained progress 

Our growth reflects the continued relevance of the IoD’s offer and the trust placed in us by directors navigating an increasingly complex environment. Our focus is not solely on attracting more members, but ensuring growth translates into greater impact.

Membership growth

Membership numbers increased for the third consecutive year, rising from 19,342 in 2024 to 19,686 in 2025. We strengthened how members connect, develop and contribute, aligning our networks, professional development and thought leadership more closely with the needs of modern directors.

Regions, nations and international

Engagement across our national, regional and international communities remained strong. Increasingly, activities are moving beyond traditional networking towards purposeful collaboration, enabling members to exchange ideas and insights, address shared challenges and promote responsible leadership.

Special Interest Groups (SIGs)

SIGs are central to supporting directors to deliver growth that is responsible, resilient and future-focused. They provide a critical link between sector expertise, regional engagement and global opportunity, enabling members to navigate regulatory complexity, rapid technological change and geopolitical uncertainty.

A more connected membership offer

During the year, we continued to transition towards a more integrated membership model. Rather than operating as distinct channels, our events, networks and professional communities are increasingly aligned as a single, connected ecosystem.

For Ellie Jobes, success at Bagnall is reflected in the opportunities it creates. Apprentices gain skills and experience through early responsibility, while the family business invests in its people, supporting development and contributing to wider social and economic value.

James Barber

CEO and Co-Founder, Harker

For James Barber, business enables others to create impact. His company supports charities to evidence their work, secure funding and extend their reach, amplifying their contribution through the many lives improved by those they support.

Linda McMillan

Chief People Officer, Fibrus Group

For Linda McMillan, business connects people to opportunity. Through the expansion of high-speed broadband to underserved communities, the business is improving access to work, education and daily life, supporting economic activity and demonstrating infrastructure’s contribution to long-term impact.

Looking Ahead

We remain focused on growing a more diverse, active membership that reflects the breadth of the UK business community. By deepening engagement and broadening participation, we increase both the relevance of our offer and the impact of membership.
