New research has ranked the cities where letting agents have the most listings.

Nottingham is top with an average of 31.4 available rental listings per agency, more than double the average seen across 21 major British cities.

The research analysed available rental property listings and active letting agency numbers across 21 major British cities this month, July 2026. 

Propoly used estimated figures for available lets and active letting agencies, based on market data sourced via Rightmove, to calculate the snapshot average number of available rental listings being handled by each agency in every city.

Across the 21 cities analysed, there were an estimated 71,536 available rental properties being marketed by 5,454 letting agencies, equating to an average of 13.1 available lets per agent. 

Nottingham recorded by far the highest level of activity, with 3,078 available rental listings being handled by 98 agencies, resulting in an average of 31.4 listings per agent.

Newcastle ranked second, with an average of 23.5 available lets per agency, based on 2,886 available rental listings and 123 active letting agents. 

Aberdeen ranked third with an average of 18.2 listings per agency, followed by Birmingham (17.2) and Leeds (16.5).

Elsewhere, Plymouth recorded an average of 15.6 available lets per agency, ahead of Bournemouth (15.3), Leicester (15.1) and Portsmouth (15.1). 

Sheffield averaged 14.9 listings per agency, followed by Southampton (14.3), while Liverpool (13.8) and Bristol (13.4) both sat broadly in line with the overall city average.

At the lower end of the rankings, London and Cardiff each recorded an average of 12.2 available lets per agency. 

Despite having by far the largest volume of rental stock, London’s 33,473 available listings were spread across an estimated 2,744 agencies, resulting in an average of 12.2 available lets per agent.

Manchester also ranked below the overall city average, with 10 listings per agency, while Sunderland averaged 11.9 and Swansea 11.1. Glasgow and Newport recorded the lowest levels of activity, with Glasgow averaging 8 available lets per agent and Newport recording just 6.8, the lowest figure of any city analysed.
