Co-operatives UK is a British co-operative federation described as "the central membership organisation for co-operative enterprise throughout the UK". It was founded in 1870 as the Co-operative Central Board, changing its name to the Co-operative Union before finally becoming Co-operatives UK following its merger with the Industrial Common Ownership Movement (ICOM) in 2001. Historically associated with consumer co-operatives, the merger broadened its scope to include worker co-operatives and it now exists to support and promote the values of the entire co-operative movement throughout the UK.
During its history it has been responsible for the organisation of the Co-operative Congresses, the establishment of both Co-operative Commissions and the creation of the Co-operative College and the Co-operative Party. The head office, Holyoake House in Manchester, is a Grade II listed building, and was built in 1911 in memory of the co-operative activist George Jacob Holyoake.
Membership of Co-operatives UK includes organisations as diverse as the Woodcraft Folk, Suma Wholefoods and the Co-operative Group. It is controlled by a board elected by its membership, is a member of the International Co-operative Alliance (ICA), the trustee of the Co-operative College, and retains a nominated seat on the National Executive Committee of the Co-operative Party.
