Surveys across the sector reveal a clear trend: one in three letting agents say more landlords are now putting their properties up for sale.

The UK’s private rented sector is being squeezed to breaking point, with rental supply collapsing to record lows as a rising wave of landlords heads for the exit, as a well known UK based professional property-buying company’s latest analysis shows.

Fresh data from the firm shows rental supply contracting far more quickly than new homes are entering the private rented sector. With only around 35% of privately let properties held on buy-to-let mortgages, most landlords have little or no debt, making it easier for them to exit swiftly when market conditions shift. 

Industry surveys underpinning the analysis indicate that 34% of letting agents have seen an increase in landlords selling up, with smaller, one- or two-property landlords driving the trend.

Debate around landlord exits has largely centred on rising interest rates, but the data indicates that borrowing pressures are not the primary driver for many sellers. Mortgage-free landlords, who make up a significant share of the sector, are less exposed to rate hikes and therefore feel little urgency to retain rental income.

Instead, analysts point to a growing list of non-financial pressures. Increasing regulatory complexity, shifting tax rules, higher compliance costs and the forthcoming Renters’ Rights Act 2025 are all cited as key reasons landlords are choosing to leave. For smaller landlords in particular, the administrative load has become a major concern.

According to Jason Harris-Cohen of the firm, the current wave of sales should not be mistaken for distress. He said many landlords remain financially stable but are opting to exit because the sector no longer offers a predictable or proportionate balance of risk and reward, as reported in recent coverage.

Across much of the UK, renters are still competing for too few homes, a mismatch that keeps options scarce and rents elevated. The latest figures suggest this strain is less about rising demand and more about the gradual erosion of rental stock, especially in regions where competition for homes is already intense.

According to the analysis, the departure of seasoned landlords often removes properties from the rental pool altogether. Many of these homes are bought by owner-occupiers, reducing the number of rentals available and amplifying the pressures facing tenants.
