The HCA said that, in 2009/10, it completed a total of 64,811 housing starts on site, against a target of 53,315. In percentage terms, that means the HCA achieved 107 per cent of its target on completions, while on starts it achieved 122 per cent.
The agency added that it had been responsible for 56,118 housing completions in England in 2009/10, against a target of 52,325.
The HCA said that more than half of the housing starts were in London, the South-East and the South-West, while more than half of the housing completions were in London, the South-East and the East of England.
Last month, the HCA revealed that it had frozen all new spending after having £230 million cut from its budget for this year and being warned by ministers that a further £610 million of funding is at risk.
HCA chief executive Sir Bob Kerslake said: "These figures further demonstrate what we believe has been a successful first year. This is an excellent result, considering the extremely fragile market, and illustrates how we are making a significant impact in areas facing the greatest challenges in maintaining a supply of affordable housing.
"This is, however, no time for complacency. Looking to the year ahead, whatever the outcome of the June Budget, it is clear that with less public funding available to support housing, we will need to focus our efforts where they have most impact at local level and drive value for money in key areas such as affordable housing."
