From SEEE Wiki
Cooperatives (and mutuals) are democratically owned businesses, which give employees, customers or members a stake in the business. As they have been operating since the 19th Century, co-operatives are often seen as forerunners of the modern social enterprise
movement. Across the UK, there are now more than 400 co-ops, employing 27,000 people, turning over more than £4.6bn per year and with combined assets of more than £22bn. They operate in sectors as diverse as agriculture, finance, housing and health as well as widely recognised retail co-ops.
In the East of England, co-operatives are represented by Co-operatives East.
Other legal structures associated with social enterprises are:
Community Interest Company - CIC
Charitable Incorporated Organisation - CIO
