London Rental Market Report: Supply, Demand, and Price Pressure in H2 2025
As London enters the second half of 2025, its rental market remains a vibrant yet challenging landscape. Driven by a persistent imbalance between available properties and an ever-growing pool of prospective tenants, rental prices continue to exert upward pressure, albeit with some moderation compared to the record surges of recent years. For landlords, tenants, and investors, understanding these nuanced dynamics is crucial for navigating what remains one of the world’s most competitive rental environments.
This report provides a comprehensive H2 2025 overview of London’s rental market, delving into average prices, the critical supply-demand balance, the impact of affordability, and how recent regulations are shaping the landscape.
1. London Rental Prices: Persistent Growth, Signs of Moderation
London’s average rental prices continue to set new records, reflecting the underlying market pressures.

- Overall Average Rent: As of June 2025, the average rent in London stands at approximately £2,249 per calendar month (pcm), marking a 7.7% increase year-on-year (Office for National Statistics, ONS). Other sources, using different methodologies (e.g., advertised new lets), place the average higher, around £2,698 pcm (Rightmove, March 2025 data).
- Recent Growth Trajectory: After double-digit growth in 2023 and early 2024, the pace of increase has shown signs of slowing. While London saw an 11.5% annual rise to December 2024, growth for new lets moderated to 2.8% to April 2025 (Zoopla). However, a significant surge in demand in May 2025 reportedly led to 10-15% year-on-year increases in some boroughs, suggesting continued volatility.
- Forecasts for 2025/2026: Experts predict rental inflation for London to range from 2.5% (Savills) to 3-4% (Zoopla) over 2025. Looking further ahead, London rents are forecast to rise by 14.2% over the next five years (Savills).
Action Point: Landlords should monitor hyper-local market data closely for specific property types and boroughs to ensure competitive pricing while optimising yield. Tenants should be prepared for continued upward pressure on rents.
2. The Supply-Demand Imbalance: A Core Driver
The fundamental mismatch between available rental properties and tenant demand remains the primary force driving London’s rental market.
- Tenant Demand: While demand has cooled slightly from its absolute peak in 2021-2022, it remains elevated. In May 2025, the market experienced a “boom” in demand, fueled by pent-up activity from earlier in the year, the student influx, and corporate relocations. This created a “supercharged” environment, with new listings often attracting multiple applications.
- The number of prospective tenants looking to move in June 2025 was 7% lower than a year ago but still 10% higher than pre-pandemic 2019 levels (Rightmove).
- Supply of Properties: The number of new rental listings coming onto the market has increased, with new properties in March 2025 being 11% ahead of the same period last year. Overall, available rental homes are 18% higher year-on-year (Rightmove). This increase is partly supported by a rise in new buy-to-let lending.
- Competition: Despite the modest increase in supply, London still faces fierce competition. While the national average of enquiries per property cooled from 16 to 12, London properties still receive an average of 8 applications per listing, highlighting the persistent imbalance.
Action Point: For landlords, proactive marketing and efficient referencing are key to capitalising on strong demand. For tenants, being prepared with all documentation and acting quickly on desirable properties is essential.
3. Affordability Crunch: Reshaping Tenant Behaviour
The sustained surge in rental prices has pushed London to an “affordability ceiling,” compelling tenants to adapt their living situations.
- Income vs. Rent Gap: Over the last five years, rents in London have increased by approximately 40%, while average wages have risen by only 31%. This stark disparity means Londoners often spend a significant portion (40-57%) of their household income on rent, a figure considered unsustainable.
- Shift to Outer Boroughs: To combat rising costs, tenants are increasingly seeking more affordable options further from the city centre. The cheapest boroughs for renters are predominantly in outer London:
- Bexley: Average £1,325 pcm
- Havering: Average £1,380 pcm
- Croydon: Average £1,420 pcm
- Even the “cheapest” inner London borough, Greenwich, averages £1,800 pcm.
- Smaller Properties & Flat-Sharing: The affordability squeeze is driving more tenants towards smaller properties or into shared living arrangements, leading to a surge in demand for flatshares.
- Commuter Belt Migration: Some higher-income renters, especially those who can work remotely or have less frequent office commutes, may consider leaving London entirely for more affordable commuter towns if mortgage rates continue to ease.
Action Point: Landlords in outer boroughs or those offering smaller, well-managed HMOs may find their properties in particularly high demand due to this affordability-driven migration.
4. Impact of Regulations: A Complex Picture
Forthcoming legislation, particularly the Renters’ Rights Bill, is casting a long shadow over the rental market, creating a complex interplay of effects.
- Landlord Sentiment & Exodus: Many landlords perceive the Bill (with its Section 21 abolition, periodic tenancies, and expanded tenant rights) as increasing uncertainty and burden. Some are choosing to exit the market, which, by reducing the overall rental stock, exacerbates the supply shortage and puts further upward pressure on rents.
- EPC Requirements: The anticipated future requirement for privately rented homes to achieve a minimum EPC Band C by 2030 (new tenancies from 2028) may also prompt some landlords to sell properties that would be too costly to upgrade.
- Real-World Rent Increases: While the Bill aims to prevent excessive rent hikes by limiting increases to once a year and allowing tenants to challenge them, the underlying severe supply-demand imbalance means landlords can still set higher ‘market-rate’ rents, leading to continued “real-world” increases for tenants.
- Professionalisation: Conversely, the Bill, along with the Decent Homes Standard, is pushing landlords to professionalise their operations, potentially leading to better quality housing stock in the long run. Some professional landlords are adapting rather than exiting, and new institutional investment in the Build-to-Rent (BTR) sector continues to grow.
Outlook for H2 2025: London’s rental market is expected to remain highly competitive through the summer, driven by seasonal demand (students, relocations) and continued supply constraints. While affordability ceilings are being reached in some areas, the sheer intensity of tenant competition, coupled with a fundamental housing shortage, suggests that price pressure will persist for the foreseeable future. Both landlords and tenants must remain adaptable and informed to navigate this dynamic environment.
