Something significant is happening in the UK rental market right now, and if you own property in London, you need to understand it.
Landlords are leaving the private rented sector at a rate not seen in modern history. Industry estimates suggest that approximately 700 rental homes are being listed for sale every single day across the UK in 2026. The scale of this exit is reshaping the London property market for buyers, sellers, tenants, and investors alike.
This is not a media panic. The data is clear, the causes are documented, and the consequences are already being felt on London streets.
In this guide, we break down exactly what is driving landlords out of the market, what it means for house prices, rental availability, and tenants in London, and what landlords who are considering their options should know before making any decisions.
The Scale of the Landlord Exit: What the Data Shows
The numbers behind this story are striking.
According to industry research published in May 2026, approximately 93,000 landlords exited the private rented sector during 2025, with a further 110,000 forecast to leave during 2026 (Source: Kalkine, May 2026).
Around 18,000 rental properties have already moved out of the lettings market since the final quarter of 2025, on top of roughly 290,000 rental homes sold out of the sector between April 2021 and October 2024 (Source: Kalkine, May 2026).
Perhaps the most telling statistic of all: 15% of homes currently listed for sale across the UK were previously rental properties, up from approximately 10% just a year earlier (Source: Kalkine, May 2026). Only a small fraction of those properties are being re-let by the new owners when they sell.
This is not a trickle. It is a sustained, structural shift in the composition of the UK housing stock.
Why Are Landlords Leaving? The Real Reasons
Understanding why so many landlords are selling is essential context for anyone navigating the London property market right now. The motivations are not simple, and they do not reduce to one single cause. They cluster around three interconnected pressures: legislation, taxation, and rising costs.
1. The Renters Rights Act 2025
The Renters Rights Act came into force on 1 May 2026 and represents the most significant change to the private rented sector in over 30 years. Section 21, the so-called no-fault eviction notice, has been permanently abolished. Every possession claim must now be made under Section 8, citing a specific ground. Fixed-term tenancies have been replaced with periodic rolling agreements for all tenancies, existing and new.
Almost two in five landlords surveyed in early 2026 said the Renters Rights Act would either force them out of the market or significantly accelerate their plans to sell (Source: Kalkine, May 2026). The removal of Section 21 in particular has changed the risk calculation for many landlords, especially smaller portfolio holders who have relied on that route as a backstop.

2. Taxation Changes Over the Last Decade
Tax has been an equally important driver of the landlord exodus. The journey began in 2017 with the phasing out of mortgage interest relief, which significantly increased the effective tax rate on rental income for higher-rate taxpayers. Additional costs have been layered on in the years since, including:
- The 3% Stamp Duty Land Tax surcharge on second properties and buy-to-let purchases
- Changes to Capital Gains Tax rates on residential property disposals
- Increasing compliance costs around energy efficiency and property licensing
For landlords who purchased properties at lower price points years ago, the combination of these changes has eroded the return profile of buy-to-let in ways that were not foreseeable at the point of purchase. Many are now weighing up whether the numbers still work.
3. Rising Mortgage and Compliance Costs
The interest rate environment of the last two years has squeezed buy-to-let landlords with mortgaged properties particularly hard. The average two-year fixed mortgage rate stands at 5.75% as of 18 May 2026, up from 4.83% at the start of March, following inflationary pressures linked to geopolitical uncertainty (Source: Moneyfacts, via MoneyWeek, May 2026).
Landlords coming off low fixed rates taken out in 2019 to 2021 are finding their monthly costs have increased dramatically on remortgage. For properties where rental income was covering the mortgage with limited headroom, this is a genuine financial pressure, not merely a theoretical one.
Add to this the ongoing requirements around Energy Performance Certificate compliance, electrical inspection reports, and property licensing in many London boroughs, and the total cost of operating compliantly has increased substantially.
What This Means for London House Prices
The flood of former rental properties onto the sales market is contributing to the significant increase in available stock across London in 2026.
According to Rightmove’s May 2026 House Price Index, the number of homes for sale is at its highest level since 2015 for this time of year, and almost a third of listings have had their asking price reduced. Homes that were correctly priced from the outset sold in an average of 36 days, while those that required a price reduction took an average of 127 days to find a buyer (Source: Rightmove House Price Index, May 2026).
For London specifically, the picture is one of downward pressure on asking prices. London asking prices are down 2.4% year-on-year as of May 2026, while London property values dropped 1.4% in the year to April, according to Zoopla (Source: Rightmove HPI and MoneyWeek, May 2026).
Knight Frank, in their Q2 2026 UK Housing Market Forecast, noted that prime central London prices are forecast to drop by 2% in 2026, with prime outer London prices expected to be flat for the year (Source: Knight Frank, April 2026).
For buyers, this represents a genuine opportunity. Increased stock, more realistic sellers, and improved negotiating power are creating conditions that have not been seen in London for several years.
A Buyer’s Market in London
Multiple estate agents and analysts are now describing London as a buyer’s market for the first time in a long time. Winkworth noted that “buyers may have a little more choice, and sellers are becoming more realistic. The best parts of central London still look good value compared with their previous peak and many other world cities” (Source: Winkworth, January 2026).
Benham and Reeves research found that the affordability ratio will fall to 8.2 in 2026, easing the home-buying journey for thousands of buyers, as wage growth outpaces house price inflation in the UK (Source: Benham and Reeves, 2026).
What This Means for London Renters
Here is the troubling consequence of the landlord exit that receives far less attention than the sales story.
Every landlord who sells a rental property is, in most cases, removing one home from the pool of available rentals. Buyers purchasing former rental properties are typically owner-occupiers. The rental stock does not get replaced. And the pace of new landlords entering the market is not keeping up with the rate at which existing ones are leaving.
Zoopla’s March 2026 Rental Market Report confirmed that rental supply remains 23% below pre-pandemic levels across the UK, and rents are still expected to rise through 2026 despite the broader market calming (Source: Zoopla Rental Market Report, March 2026).
The average rent for a new let in the UK stands at £1,319 per month as of March 2026, having risen 1.9% over the past year (Source: Zoopla Rental Market Report, March 2026). While the pace of growth is slowing from the extreme levels seen in 2022 and 2023, rents are not falling. The structural shortage of rental homes is keeping the floor elevated.
For London renters specifically, the picture remains tight. Demand from professionals, students, and international workers remains robust. With fewer rental homes available and landlords exiting the sector, competition for quality properties is not going away.
Zoopla forecasts that rents for new lets will rise by 2.5% across the UK in 2026, with Winkworth forecasting approximately 2% growth in average advertised rents for the year (Source: Zoopla, via Big Issue, 2026; Winkworth, March 2026).
Should London Landlords Sell in 2026?
This is the question many landlords are asking, and it deserves an honest answer rather than a reflexive one.
The case for selling is not unreasonable. Higher mortgage costs, increased regulatory obligations, the removal of Section 21, and a window of elevated buyer demand due to high stock levels all make 2026 a viable time to exit if you have been considering doing so.
However, the case for staying is equally coherent. Rental demand in London remains structurally strong. Rents are still rising, albeit more slowly. The landlords who are exiting are, in many cases, those with smaller portfolios, mortgaged properties, and limited professional management support. Landlords with equity-heavy portfolios and professional management in place are typically absorbing the regulatory changes more comfortably.
Winkworth noted that buy-to-let mortgage data in 2026 shows an increase in both new purchases and remortgaging activity, “suggesting that some investors are taking advantage of improved borrowing conditions and choosing to hold onto rental stock rather than exit the sector” (Source: Winkworth, March 2026).
The decision should not be made based on headlines alone. It should be made based on your specific portfolio, your mortgage position, your tax situation, and your medium-term goals. That is a conversation worth having with a professional who understands both the current regulatory environment and the London market in detail.
What Happens Next: The Outlook for the Rest of 2026
Knight Frank forecasts UK house price growth of 1.5% for the full year, down from earlier forecasts of 3%, with expectations of 3% growth in 2027 and 4% in 2028 as market conditions stabilise (Source: Knight Frank, Q2 2026 Housing Market Forecast).
For London specifically, the broad consensus among analysts is that prices will remain flat to modestly lower in 2026, before recovering more meaningfully in 2027 and 2028 as mortgage rates ease further and pent-up demand returns.
The key uncertainty for the rest of 2026 centres on interest rates. The Bank of England’s ability to cut rates has been constrained by renewed inflationary pressure. If rates begin to fall again in the second half of the year, both buyer confidence and landlord borrowing economics will improve, which could slow the rate of landlord exits and stabilise rental supply.
On the regulatory front, the PRS Database is expected to launch in late 2026, which will require all private landlords to register. Failure to register will affect the ability to use certain possession grounds under Section 8. Landlords who are not already aware of this deadline should factor it into their planning now.
