Chief executive of the HCA, Pat Ritchie, said: “This is a good result and we are where we expected to be in our delivery programme.
“We will be reviewing and monitoring delivery for the coming year of the Programme, to ensure that our funding offers the best value for public money and helps meet government aspirations of delivering up to 170,000 new homes by 2015.”
Housing minister Grant Shapps said: "Far from the predictions of the doom merchants, today's figures show work has started on over 15,000 new affordable homes since last September - a massive increase on the previous six month period.
“This is clear evidence that our efforts to get Britain building are starting to yield impressive results.
“This rapid and dramatic progress means that we are well on track to exceed all original expectations and deliver up to 170,000 new affordable homes over the next few years.”
