More than half of landlords planning to reduce their portfolios intend to leave the private rented sector entirely, according to new figures from LandlordBuyer, pointing to a significant and potentially lasting shift in the UK rental market.
Why landlords are walking away
The 57% figure emerges against a backdrop of mounting pressure on private landlords. Higher mortgage costs, increased taxation, rising maintenance expenses and sweeping legislative reform have combined to make the economics of buy-to-let considerably harder than they were just a few years ago. House prices have remained broadly flat through the first half of 2026, removing capital growth as a cushion against tightening margins.
The introduction of the Renters' Rights Act has sharpened decision-making for many. The removal of Section 21 notices and the arrival of new tenancy rules represent the most significant legislative overhaul of the private rented sector in a generation, and for landlords already operating on squeezed margins, the reforms have prompted a fundamental reassessment of long-term plans.
"What makes this statistic so significant is that we're not simply seeing landlords sell one or two properties," said Jason Harris-Cohen, managing director of LandlordBuyer. "More than half of those reducing their portfolios are looking to leave the sector entirely."
Harris-Cohen pointed to the changed investment case for buy-to-let. "Many landlords have enjoyed strong returns over the last decade, benefiting from rising property values and consistent rental demand. However, the economics of buy-to-let have changed considerably. The combination of higher borrowing costs, increased regulation and slower capital growth means many investors are reassessing whether the effort and risk are still worthwhile."
The rental market implications
Despite the growing volume of exits, rental demand remains strong across much of the UK. Average rents rose 3.5% in the year to April 2026, reaching £1,381 per month, with some regions continuing to see substantial growth. For many landlords, however, that has not been enough.
"At LandlordBuyer, we're speaking to increasing numbers of landlords who have reached a natural decision point," Harris-Cohen said.
"They've built up significant equity over the years and are now looking at alternative investments, retirement planning or simply reducing the amount of time and responsibility involved in managing property."
"Many are choosing to sell while market conditions remain stable, particularly where they can achieve a quick sale and avoid the uncertainty of future regulatory changes," he added.
Industry observers warn that the trend carries wider consequences. If landlord exits continue at scale, a sustained reduction in available rental stock could place further upward pressure on rents in already stretched markets. With rental demand expected to remain resilient through the rest of 2026, the supply side of the equation looks increasingly fragile.
The 57% figure may yet prove to be one of the defining data points of the year, marking the moment a critical mass of landlords concluded that the private rented sector no longer offered the returns to justify staying in.
