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. Consumer loan and reliable savings - these are the main goals, which mean "natural persons" having decided to unite in credit consumer cooperative. In the UK, credit unions are a source of financing of people groups. This tool is not widely used. Standards by which credit unions build their work do not coincide with the standards and regulations of consumer cooperation of the usual type. The right to use the services of the credit union have only its members. The specifics of credit unions and, in some sense, their uniqueness lies in the fact that they work not for profit and do not appropriate profit.
