FC United of Manchester

FC United of Manchester is the UK’s largest 100% fan-owned football club — founded by supporters who refused to accept that football should be about profit over people. Formed in 2005 by Manchester United fans who stood up against the Glazer takeover, we built something new: a democratic, community-driven club where every member has an equal say, and where the game remains affordable, inclusive, and rooted in local values. Based at Broadhurst Park in Moston, we compete in the Northern Premier League and continue to show that a different kind of football is not only possible, but thriving. As a Community Benefit Society, everything we do is about creating social value — from delivering education and health programmes to running grassroots sport and championing inclusion. We don’t just play football. We use it to bring people together, change lives, and prove that fans, when united, can build something powerful and lasting: ⚽ Responsible ownership in football – Football clubs should serve their supporters and communities, not private interests. We’re committed to transparency, long-term sustainability, and making decisions that benefit the many, not the few. ⚽ Affordable football – The game should be accessible to all. That’s why we keep ticket prices low, offer flexible season tickets, and make sure families, young people, and those on lower incomes aren’t priced out of matchdays. ⚽ Protecting fan culture – Football is nothing without its fans. We’re proud to protect the traditions that make matchdays special—standing terraces, a passionate atmosphere, and a club that listens to supporters, not sponsors. ⚽ Inclusivity – Everyone is welcome at FC United. We believe in football without barriers, bringing people from all backgrounds together through love of the game. ⚽ Sustainability – We’re committed to doing our part for the planet, from backing local green initiatives to making our operations more environmentally friendly. Be part of it!
