Partnerships UK chief executive James Stewart said at Partnership for Schools annual conference that that BSF was one of the bright spots in the construction industry at the moment.
He added: “I think we have not reached the bottom of this market yet and the events of the last few days have proved that.”
Mr Stewart said that while banks were very reluctant to finance deals and contractors needed to bring in more banks.
“We have seen a reduction in spending… But the banks are still lending.”
He said he though BSF was faring the best of the PPP projects out there because the programme was expected to last a long time and because the developments were small and it was easier to borrow £100 million than £500 million.
He added “BSF is okay and banks are open.”
