The social lender Triodos Bank increased its UK loan book by a record 26 per cent in 2010, to a total of £312m.
The bank said it had paid out approximately £80m in new loans last year, and had also increased its lending commitments by 11 per cent to £180m.
Lending and commitments to social organisations, such as charities, social enterprises, housing associations and healthcare organisations, grew by 23 per cent.
The bank told Third Sector last year that the lender was expecting total lending to grow by about 25 per cent in 2010.
Bevis Watts, head of business banking at Triodos, said the bank's success proved there was "an alternative to socially useless banking".
