Tower Hamlets is the second most affordable London borough for home buyers.

The latest figures published in research by Property Partner , showed the average house there cost a little under nine times the average salary in 2015.

It was only beaten by Barking and Dagenham where the equivalent property was 7.26 times a typical annual wage packet.

However, both these figures were still far above the Bank of England’s recommendation that mortgage lenders restrict borrowing to 4.5 times salary. Nowhere in England, according to the study, fell below that threshold.

Property Partner analysed data from the Department For Communities And Local Government from the year 2000 to 2015.

These showed the median salary in London in 2015 was £34,320 meaning even in the cheapest borough buyers could expect to pay around £249,163 for a home.

Overall house prices in 28 of the 33 London boroughs were found to be at least 10 times average salaries including Newham at 10.1, Greenwich at 10.62 and Lewisham at 11.32.

In 2000 only Kensington and Chelsea rose above the same threshold with a ratio of 14.43.

It remains the most expensive borough with prices 38 times earnings in 2015, an increase of 164%.

Tower Hamlets house prices have accelerated away from earnings at a much slower rate, with 61% increase since 2000, when homes cost 5.41 times earnings.

Affordable housing in the capital was a key electoral battleground in the race to become the new Mayor of London and CEO of property Property Partner, a real estate crowdfunding platform, Dan Gandesha said whoever took over needed to tackle the issue better than either Ken Livingstone or Boris Johnson had.

He said: “This research shines a harsh spotlight on the desperate issue of affordability in the capital.

“Whoever wins needs an innovative approach to help resolve the supply crisis.”

He said the solution needed to be “radical” with housebuiling needing to double and building on the green belt seriously considered.

“Perhaps the British obsession with mass home ownership needs to change too. With government support for build-to-rent initiatives, long-term renting could eventually fill the gap, with larger institutional landlords taking over the sector, providing affordable rents and professionally-managed properties rather than multiple, small private ones.”

The survey also revealed Hackney had become less affordable, more quickly than any other area in the UK in the last seven years.

In 2008 house prices in the borough were 8.58 times the median earnings of £28,330, in 2015 they were 14.68 times the median salary of £35,140, an increase of 71%.

At first glance the City appeared to have beaten this as houses prices were 7.7 times earnings in 2008 and 15.2 times in 2015, an increase of 97%. But in that period the median salary there had risen at a faster rate from £53,110 to £63,620.

London remains the least affordable place in England to buy a home with prices 11.04 times earnings on average. The most affordable area is the North East where the ratio is 4.93.
