Quarterly housing registrations have jumped by almost 5,000, bringing the total for the period between December and February to 26,004.
And February 2013 – the most recent month for which figures are available – saw affordable registrations more than double from 1,373 in 2012 to almost 3,000 this year.
The figures, for the period December 2012 to February 2013, show most activity in London, followed by the South East and East of England.
NHBC attributed the growth to the government’s £2.2bn Affordable Homes Programme – which plans to deliver 170,000 new homes by April 2015 – and schemes such as NewBuy and Funding for Lending.
All 170,000 homes on the AHP have to be built by the 2015 deadline.
NHBC commercial director Richard Tamayo said: “The big rise in new homes being registered – particularly affordable homes – is very encouraging news for Britain’s housebuilding industry which has been through a very difficult time in recent years.
“The dramatic rise in affordable homes is good news for first time buyers and social housing tenants. However, it is important that quality is not compromised in the rush to build these new houses before the Government’s April 2015 deadline.”
“These figures, combined with the boost for housing announced in the Budget, are a welcome shot in the arm for builders up and down the country.”
