These groups promote or operate as co-operative structures, which are social enterprises owned and democratically controlled by their members.
There are close to 7000 co-ops in the UK ranging from the high street supermarket, to housing co-ops, to food co-ops, car co-ops and everything in between.
The guiding co-operative principles are open and voluntary membership, democratic control, member participation, autonomy and independence, concern for community, and co-operation among co-operatives.
