Families in west London are the most likely to have failed to benefit from the Government's Help to Buy schemes.
Just two homes out of 5,200 sales over the past two years in Kensington & Chelsea were bought using Help to Buy, while it was eight out of 5,609 in Hammersmith & Fulham and 10 out of 6,899 in Westminster.
The £600,000 purchase price limit may be behind the low number of purchases under the scheme within these expensive areas.
Families in Hounslow and Hillingdon were the most likely to benefit from the schemes, with the number of homes bought using the scheme making up 2.5% of the total - although this is still almost half the rate of England as a whole.
In the two years from April 2013 to March 2015, 280 homes in west London have been bought using the Mortgage Guarantee scheme and 334 through the Equity Loan scheme.
The figures are based on completions through both the Help to Buy (Equity Loan) scheme, which covers April 2013 to March 2015, and the Help to Buy (Mortgage Guarantee), which covers October 2013 to March 2015.
The number of house sales comes from the Land Registry for the period April 2013 to March 2015, compiled by the Trinity Mirror data team.
The Help to Buy equity loan scheme, which is available only in England, will provide £3.5bn of additional investment to help people into home ownership. The scheme will help up to 74,000 home buyers, as well as providing a boost to the UK's construction sector.
Under the scheme, the government will provide an equity loan worth up to 20% of the value of a new-build home, interest free for the first five years, which can be repaid at any time or when the home is sold.
The scheme is available to both first-time buyers and those looking to move up the property ladder, with a maximum home value will be £600,000 and there will be no income cap constraint.
The Help to Buy mortgage guarantee scheme has been open since October 2013 and is available across the country.
Under the scheme, the Government offers lenders the option to purchase a guarantee on mortgage loans where the borrower has a deposit of between 5% and 20%.
The scheme can be used for mortgages on both new-build and existing homes, and can be used by first-time buyers, home movers and for those remortgaging.
