The average rent for a one bed property has reached £1,329 per month as nearly one in three London households are renting privately.

In Kensington and Chelsea, tenants are sacrificing 81% of their monthly salary on rent, the highest out of all the London boroughs.
Those in Hackney give 81% of their monthly salary to pay for rent closely followed by Westminster where single tenants use up to 79%.
Single tenants in Bromley and Havering spent the lease of their monthly salary on renting their one bedroom properties in London at 42%.
Robby Du Toit, managing director of Sell House Fast, said: “As demand has consistently exceeded supply over the last few years, Londoner’s have unfortunately been caught up in a very competitive property market where prices haven’t always reflected fair value.
“For those single tenants with ambitions to climb up the property ladder – their intentions are painfully jeopardised, as they can’t set aside a sufficient amount each month to save up for a deposit or explore better alternatives.
“It’s not only distressing for them but worrying for the property market as a whole – where the ‘generation rent’ notion is truly continuing too spiral further.”
