In 32 per cent of cases, projects have been put back by at least one year, the study said. Meanwhile, the public sector is taking on an increasing share of the funding of the top regeneration projects.
The public sector has committed to £8.26bn of spending this year on 65 projects compared to a commitment of £4.92bn on the same projects in 2008. In contrast, the private sector's committed funds increased by 26 per cent, from £8.2bn in 2008 to £10.3bn.
The switch is partly attributed to the need for projects to be seen by banks as low risk, to attract loans.
The average number of planned homes per scheme has fallen by one per cent.
