More than 17,000 homes have been bought under the Government's Help to Buy scheme, according to the latest official figures.
The vast majority (80%) have been bought by first time buyers, while 77% have been purchased outside of London and the South East.
The figures were released today by Downing Street, just days after George Osborne announced it was to be extended until 2020 with a £6 billion boost in the budget to help an estimated 120,000 more households purchase a new-build home.
Prime Minister David Cameron said: "Help to Buy is a key part of our long term economic plan, giving thousands more people the security and independence that comes from owning their own home."
Of the 17,395 homes purchased with the Help to Buy scheme the vast majority (14,823) were bought using the equity loan option while 2,572 were bought using the mortgage guarantee element.
The two-part scheme enables buyers to get on the house ladder with as little as a 5% deposit with a loan from the Government, but there are growing concerns the initiative is fuelling a housing bubble.
Earlier this month Halifax warned the scheme was pushing house prices further out of some people's reach by creating strong demand in a market where the supply of properties was not keeping up.
There are also concerns in particular that the second phase of the scheme - the mortgage guarantee offered on new and existing homes worth up to £600,000 - is pushing prices too high in London and the South East.
However, it is thought Help to Buy had such a dramatic initial impact due to pent-up demand from those previously shut out of the property market, and that this clamour may now be beginning to fade.
The figures show the average house price was £194,992 with the most sales made in the South East.
Uptake of Help to Buy has been the least popular outside of England, with only 33 sales in Northern Ireland, 416 in Scotland and 131 in Wales.
Labour argued the cost of housing would remain high unless more properties were built to meet the demand.
Emma Reynolds MP, Labour's shadow housing minister, said: "Any help for first time buyers struggling to get on the property ladder is to be welcomed.
"But rising demand for housing must be matched with rising supply if this scheme is to bring the cost of housing within the reach of low and middle-income earners.
"Instead, under this Government house building fell to its lowest level in peacetime since the 1920s and home ownership continues to fall.
"You can't deal with the cost-of-living crisis without building more homes."
State-backed Lloyds Banking Group, which includes Lloyds Bank and Halifax, said by the end of January it had seen 1,435 home purchases completed through the mortgage guarantee part of the Help to Buy scheme.
The group said the average property value was £146,147, with eight in 10 applications from borrowers outside London and the South East and more than 85% from first-time buyers.
Mortgage director Stephen Noakes said: "The applications - across the UK - show that the scheme is helping those that can afford the monthly payments but until now, have not been able to get the necessary deposit."
Lloyds, which is 33% owned by the taxpayer, said it continued to be a strong supporter of the equity loan element of Help to Buy and that at the end of 2013 it accounted for 58% of the market.
