Today in the UK there are about 700 credit unions with assets exceeding 200 million pounds. When organizing the credit union it is important that people know each other and know the extent to which each of them is trustworthy. Credit union promotes the effective conservation of personal funds of its members, giving them the loans from the funds of the credit union, as well as the sharing of savings in education, housing, health care and other programs of social support and social development of its members. Cooperation between credit unions, how they would not have been named, took place always, from the moment when the movement moved outside one credit union. Credit unions historically formed as a special form of social support, initially taken upon themselves the social mission of protecting the interests of citizens in the field of financial services.
