The affordability "gap" between wages and house prices has grown up to 40% in parts of east London, according to exclusive figures.

The median house price in Shoreditch was 14.4 times greater than the annual median wage in 2014, a huge increase of 41% on the equivalent figure of 10.2 greater for 2010.

In Bethnal Green and Bow prices are 12.6 greater than the average wage compared to 9.4 times in 2010, an increase of 34.3%.

In Poplar and Limehouse prices prices are 10 times the media wage, a rise of 19.7% on the last election with only East Ham, which covers the Docklands, keeping reasonable pace with pay. Prices are 8.9 times the average median wage compared to 8.0 the last time the country went to the polls, a rise of 11.8%

Elsewhere in London, the median house price in Westminster North was 18.9 times greater than the annual median wage in 2014, a huge increase of 67% on the equivalent figure of 11.3 for 2010.

Only Vauxhall, out of 573 in England and Wales has seen a bigger decrease in its residents’ ability to afford housing in the area.

The constituencies of Kensington and Chelsea and Fulham were also in the 10 areas where house price affordability had fallen most since 2010.

In Kensington the average house price in 2010 was 16.3 times as much as the average annual wage in the area, compared to 26.6 times greater in 2014.

This equates to housing becoming 63% less affordable in the constituency.

In the average English and Welsh constituency, house prices were around 4% less affordable in 2014 than they were in 2010.

However, this figure hides some huge differences in house price affordability across the country.

The least affordable area of the country is also, unsurprisingly, located in central London with average house prices in Chelsea and Fulham currently 26.9 times greater than the median wage in the constituency.

Economists believe the greatest policy in the battle to keep homes in line with wages is to build more houses.

However, George Osborne pressed more fiscal levers in his Budget, pledging to help first-time buyers through a new Help To Buy Isa. For every £200 saved towards a deposit for a first home, the Government will give a bonus of £50.

This policy has come under fire from the Institute for Fiscal Studies (IFS) which said that it would add further “distortions” to the market and only assist those on the right path to finding a deposit anyway.

IFS economist Stuart Adam told the Telegraph: “There will be some people who will be persuaded to save more as a result of the policy, but certainly those who will find it easiest to qualify for the maximum top-up [of £50 a month] are those who have the money anyway or have wealthy parents.”

“If policymakers are genuinely worried about housing affordability, then they need to focus more on [planning reforms]. It is very sclerotic, and on top of that the Government itself isn’t building houses in a way that social housing was built in decades past.”
