Britain's private rented sector has grown by an estimated 6.6% over the past decade, according to new research from LegalforLandlords, though the figures reveal sharply different trends across England, Scotland and Wales.
Analysis of rental market data between 2015 and 2025 shows the estimated size of Britain's PRS increased from 2.98 million properties to 3.17 million. For landlords and investors, the more revealing story lies in how that growth has played out regionally, and what it means for returns.
England has driven the overall expansion, with rental stock rising by 10.1% over the decade and adding more than 240,000 homes to the market. Scotland and Wales have moved in the opposite direction, with rental supply falling by 6.3% and 10.6% respectively.
The contrast points to how differing housing policies and regulatory approaches across the three nations have shaped landlord confidence and investment decisions.
Average rents have climbed substantially across Great Britain over the same period. In 2015, the average monthly rent stood at £924; by 2025, this had reached £1,343, a rise of 45.3%. Sustained tenant demand, combined with constrained housing supply in many areas, has underpinned the increase.
House prices, however, have grown even faster. The average house price across Great Britain rose from £178,966 in 2015 to £270,783 in 2025, an increase of 51.3%. Because property values have outpaced rental growth, average yields have remained largely stable rather than improving:
- 6.2% in 2015 compared with 6.0% in 2025
- PRS size: up 6.6% (2.98 million to 3.17 million properties)
- England rental stock: up 10.1%
- Scotland rental stock: down 6.3%
- Wales rental stock: down 10.6%
- Average rent: up 45.3% (£924 to £1,343 per month)
- Average house price: up 51.3% (£178,966 to £270,783)
- Average yield: 6.2% in 2015 versus 6.0% in 2025
Sim Sekhon, group chief executive at LegalforLandlords, said the divergence between nations was one of the most striking findings. "These figures paint a fascinating picture of how Britain's rental market has evolved over the last decade. While rental supply has increased overall, the divergence between England, Scotland, and Wales is particularly striking and may reflect how different policy environments influence landlord confidence and investment decisions."
"At the same time, rents have risen substantially as demand has continued to outpace available housing, creating affordability challenges for many tenants. What's notable is that despite rents increasing by more than 45%, landlords have not seen a corresponding increase in yields because property values have risen even faster."
Sekhon added that the sector's ability to absorb a decade of upheaval points to underlying resilience, though he cautioned that future policy decisions will shape whether supply can keep up with demand. "The result is a sector that has demonstrated resilience through a period of significant regulatory change, tax reform, economic uncertainty, and shifting tenant expectations.
"As policymakers continue to consider reforms to the private rented sector, maintaining a healthy balance between tenant protections and investment incentives will be essential if rental supply is to keep pace with demand in the years ahead."
