Figures recently unveiled by the Office for National Statistics (ONS) showed that rent prices in London rose by 6.2% year-on-year in September, up from 5.9% in August.
This figure marks the biggest increase of any region in the UK and the biggest jump since data began to be tracked in 2006.
Rent prices in London make up almost 1/3 of the country's rental spending, with tenants in the city seeing costs hit new highs this year.
London is facing a shrinking supply of apartments available to rent, which has enabled many landlords to raise their rents and "desperate" tenants to overbid for homes.
Rental platform Goodlord found last month that almost half of UK landlords have tried to sell their property in the past year, with more than three-quarters of respondents in London citing high mortgage payments as a reason for exiting the market residence.
