Property Investments UK has analysed the capital using criteria such as tenant satisfaction, affordability, and the number of rented properties.
Tower Hamlets topped the list with 89,513 rented properties, but only 69 per cent of tenant satisfaction.
The borough’s rental demand is partly attributed to its large student population and 582 transport stops, making it appealing to commuters.
Robert Jones from Property Investments UK said: “Tower Hamlets continues to thrive as a rental hotspot, particularly for students and young professionals.
“Its proximity to Canary Wharf and excellent transport links make it a desirable location, though affordability concerns may be a growing challenge for long-term renters.”
Hackney followed closely with 77,351 rented properties and a 64 per cent tenant satisfaction rate.
With 444 transport stops, it remains a preferred choice despite its low affordability ratio of 13.66.
Mr Jones added: “Hackney’s popularity stems from its vibrant social scene and creative industries, making it a hotspot for young professionals.
“However, rising costs may push renters to seek more affordable alternatives in neighbouring boroughs.”
Westminster, with 68,159 rented properties, remains a sought-after rental location, thanks to its large student population and 693 transport stops.
However, its high house-buying affordability ratio of 18.04 limits ownership options.
On the other end of the spectrum, Havering and Bexley emerged as the least renter-friendly boroughs.
Havering has 29,921 rented properties with a tenant satisfaction rate of 65 per cent, but limited transport stops and a lack of university presence make it less appealing to transient renters.
Bexley, with 28,620 rented properties, also suffers from low tenant satisfaction (53 per cent) and a lack of rental-focused amenities.
Mr Jones noted: “Havering’s strong employment and affordability make it ideal for families looking to buy rather than rent.
“Bexley’s affordability makes it attractive for first-time buyers rather than renters.”
Bromley, Sutton, and Richmond upon Thames also featured among the least renter-friendly boroughs.
Robert Jones at Property Investments UK warned: “Renting in London is increasingly becoming a long-term reality for many, as rising house prices and mortgage rates outpace wage growth.
“Inflation and high living costs make it more difficult for renters to save for a deposit, keeping rental demand high across the capital.”
