The gross lending volume of bridges during H1 2012 was 130% higher than H1 2011.
Secured and second charge loan numbers were also up sharply during the first half of this year relative to the first six months of 2011.
The overall number of loans arranged was 40% higher while gross lending volumes rose by 55%.
Danny Waters, CEO of Enterprise Finance, said: "This first half data confirms what most in the short-term finance industry already know: the bridging sector is experiencing rapid growth.
"There is not only more demand relative to a year ago, but the loans people are taking out are also a lot bigger on average, which reflects both borrower and specialist lender appetite.
"While the secured loans sector is still a shadow of its former self, it has certainly come back from the brink. Cheaper rates and improved supply from new and existing lenders have injected all-important liquidity into the sector. We expect secured loans to be particularly robust in the short to medium term, as loan availability increases to meet strong demand."
