Surrey County Council sets up or backs current credit unions like Surrey Saver
In a similar way to the building investment given through buildsurrey.net that has given investment of over £400k to businesses for infrastructure projects in Surrey http://news.surreycc.gov.uk/2013/05/16/firms-win-400000-of-council-deals-as-surrey-lands-government-business-award/
This would help the promotion, stability and lending & investment opportunities of credit unions - increasing their available credit to lend to their members, rather than credit unions having to wait for more investors before they can lend.
There is a return on investment built in and at a more reasonable rate to the applicant than from highstreet banks. Works on a basis of responsible lending and was mentioned this week at PM Questions as a means to reduce the growth of pay day lenders.
Any return can be invested in other projects such as buildsurrey.net which includes schools improvements or other things like roads, public transport etc
