The number of homes sold on the Right to Buy scheme rocketed across west London last year.

Hounslow recorded a giant leap as sales in the borough went from 13 in 2013 to 134 in 2014, 10 times higher than the previous year.

In neighbouring borough Hammersmith and Fulham, sales more than doubled in a year climbing from 37 to 88, while in Hillingdon, they were up from 105 to 189. And in Harrow they jumped from 26 to 45.

Across west London, Right to Buy sales have soared to 774 in 2014, up by three quarters from 434 sales in 2013, and nearly 27 times higher than the 29 sold through the scheme in 2009.

The statistics were compiled by the Trinity Mirror Data Journalism Unit from statistics released by the Department for Communities and Local Government (DCLG).

Since April 2012, local authorities have been allowed to keep receipts from Right to Buy, with the aim that each home sold through the scheme will be replaced with a new affordable home to rent.

Despite selling 1,282 homes through the scheme during that period, just 28 homes have been acquired or construction started across the whole of the west London area over this period, five in Hounslow, 13 in Kensington & Chelsea, and 10 in Westminster.

In 2014, 12,361 homes were sold through Right to Buy in England, up from 10,329 in 2013, and 1,572 new dwellings were started or acquired.

Sales were at their highest in 2007 at 13,982 and at their lowest in 2009 with 1,891 sales.

Since April 2012, when the new policy of one-for-one replacement was brought in, 2,712 new properties have been acquired or started to replace 22,690 - or one replacement for every eight sold.

In the third quarter of 2014-15, between October and December, local authorities sold an estimated 3,285 homes under the scheme, an increase of 15% in the same quarter of 2013-14. London accounted for 33% of sales.

Receipts local authorities received during this period were approximately £247m from Right to Buy sales, 26% higher than the £197m in the same quarter of 2013-14.

There was a downward trend in Right to Buy sales in the mid 2000s, and the number of sales decreased greatly between 2006-07 and 2009-10 (possibly caused by the financial crisis). Sales were relatively stable for the next couple of years until 2011-12.

The increase in Right to Buy sales since then may, in part, be explained by the increased discounts available to tenants since April 1, 2012, the reducing of any effect of the financial crisis and the increased marketing surrounding the changes.

In April 2012, DCLG changed the maximum cash discount available for Right to Buy sales to £75,000 across England.

In March 2013, in recognition of the increasing property prices in London, the government increased this amount to £100,000 for tenants living in London boroughs.

Since July 2014, DCLG changed the maximum cash discount available to £77,000 in England and £102,700 in London.
