Construction will start on a third fewer social homes next year, in a vivid sign of wider impending restraints on government spending.
The news comes as the country's new property quango reveals that the value of its development assets has plunged £1.1bn as a result of the housing crash.
Gordon Brown made social housing one of the government's main priorities in June when he announced an extra £1.5bn for new homes. The flagship promise meant shifting funding from various other departments including transport, health, education and the Home Office.
But this financial fillip will only have a temporary impact, according to targets set by the Homes and Communities Agency, the property quango.
Overall completions will continue to rise from a total of 55,625 this year to 61,500 next year, partly as a result of the government's injection of money. But housing starts will drop away next year, suggesting that there will be fewer completions in the coming years.
Only 29,900 grant-funded housing starts are scheduled for 2010-11, a drop of 34 per cent from the 45,500 target for the current financial year. Of those, the number of "social rented" homes built under the National Affordable Housing programme will halve from 30,389 in 2008-09 to 14,500 next year.
Ministers face an uphill struggle because each unit of social housing now requires a much larger government grant than before the credit crunch.
For the three years to 2011, the social house building target has fallen to 116,576 from 156,000 before the property crash. As a result it will be much harder for Mr Brown to highlight social housing in next month's pre-Budget report without shearing funding once again from other departments.
The news comes as the HCA today (10th November) reveals that the value of its development assets has fallen from £1.9bn to under £800m.
The agency owns vast brownfield sites around the country which rose rapidly in value during the boom but are now worth only a fraction of their previous value. The drop includes an impairment charge of £540m and a £600m reversal of gains made during the rising market.
The quango said this was an accounting write-down that would not affect its ability to build new homes. However, it admitted that the drop in proceeds from the sale of land and buildings - down to £51m last year compared with £333m the previous year - could have an impact.
The HCA will say in its annual report today that it has completed 53,000 new homes in the past year, which saw its creation from the merger of the old English Partnerships and Housing Corporation quangos. Bob Kerslake, chief executive, will say the group has spent £3.9bn through its housing and regeneration programmes. Circumstances have been "particularly challenging" for the entire housing market, he is to say, but the HCA has "maintained the momentum" of its programmes.
The agency will also write off £13m after the insolvency of a private developer with which it was working - now why doesn't any of this surprise me??
