Average rents agreed across the UK remained broadly flat in 2025, despite a rise in the number of homes coming to the rental market, according to the latest annual analysis from Propertymark.

The Propertymark Annual Rental Price Report 2024/25 shows that the overall average let agreed by tenants stood at £1,505 per month during 2025, marginally below the £1,511 recorded in 2024. Over the same period, the average number of rental properties newly marketed each month rose from 99,739 to 108,348.

In total, 1,300,514 rental properties were newly marketed during 2025. Propertymark cautioned that this figure does not represent a net increase in rental stock, as it reflects factors such as tenant churn and re-lets, rather than additional homes entering the sector.

SUPPLY AND PRICING TRENDS

While headline rental prices appear broadly static year on year, Propertymark said this masks considerable variation depending on property type, location and seasonal trends. The highest average let agreed in 2025 was recorded in October, at £1,629 per month, which also proved to be the busiest month for new rental listings, with 146,724 properties coming to market.

At the other end of the scale, January was the cheapest month for tenants in 2025, with an average let agreed of £1,459. December saw the lowest level of supply, with just 78,806 new properties marketed.

By comparison, 2024 saw average monthly rents rise through the summer, peaking at £1,582 in September. Supply that year was strongest in October, when 120,343 new properties were listed, before falling sharply in December.

LEGISLATIVE PRESSURES

Commenting on the findings, Nathan Emerson, chief executive at Propertymark, said: “The UK’s private rental sector has undergone profound changes over the last 12 months, with the Renters’ Rights Act in England and the Housing (Scotland) Act being two of the most recent and notable examples.

“Such changes have brought much needed new protections for many tenants, however, have added additional pressures on landlords in terms of more complex tax frameworks and future demands regarding aspects such as energy efficiency.

“As we head into 2026, it may well become a year for adaptation, as various new legislation is implemented in phases throughout the year. The rental sector is likely to face challenges and achievements in likely close measure; however, it remains imperative the sector attracts new long-term investment to keep pace with ever growing demand.”

ABOUT THE DATA

The report is compiled using agency-level data from across the industry, covering agreed rents and the number of properties newly coming to market each month between January 2024 and December 2025. Propertymark stressed that the figures represent a snapshot of activity among contributing agencies and are influenced by the type and location of properties included in the analysis.
