The bank began offering specialist funding to SMEs two years ago and the increase has taken the total value of its book to more than £800m and total assets to more than £1bn.
Aldermore said it supports more than 9,500 business customers.
Ian Wilkins, group managing director of commercial finance at Aldermore, said: “At a time when the big banks are falling short of their business lending targets, Aldermore is exceeding all expectations.”
He said that Aldermore’s Invoice Finance business made more than £130m of funding available to SMEs in July, up 42% on the same period of 2010.
In addition, its Asset Finance business, which began lending last year, increased the group’s balance sheet by £100m, with £32m of new loans written in July.
Wilkins said: “We have clearly demonstrated our ambitions and willingness to lend to deserving small and medium sized businesses throughout the country.
“In a short space of time we have developed a specialist SME lending proposition which is in tune with the needs of our customers and is capable of providing a fast, reliable and high quality service.”
