Fresh research suggests that the UK’s private rented sector may be heading in the opposite direction to what the government has been claiming, with the supply of rental homes continuing to decline across much of the country.
While ministers argue that the private rented sector has doubled in size since the early 2000s, new figures indicate that available rental stock is shrinking rapidly, particularly in London and other major urban areas.
The latest analysis, carried out by Savills for The Telegraph, highlights a growing imbalance between the number of homes available to rent and the number being placed on the sales market.
Rental supply falls sharply in London
According to the research, the number of rental properties available in London has dropped by 21.7% compared with two years ago.
At the same time, the number of homes being listed for sale in the capital has increased by 17.6%.
This shift suggests that many landlords may be choosing to exit the private rented sector altogether, putting their properties up for sale instead of continuing to let them.
The trend appears even stronger within the flat market, which has traditionally attracted a large share of buy-to-let investors.
Flat sale listings in London reportedly rose by 30.9%, reinforcing the view that landlords are steadily reducing their exposure to the rental market.
Similar trends emerging across the UK
The pattern is not limited to London.
Across the wider UK, the number of homes available to rent has fallen by around 17% over the past two years, while homes listed for sale have increased by roughly 10%.
Nationally, homes advertised to let are estimated to have declined by 20.6%, while properties entering the sales market rose by 14.8%.
These figures point towards a broader restructuring of the market, where landlords are reassessing whether remaining in the sector still makes financial sense.
Why landlords are leaving the market
Several factors appear to be driving this shift.
Many landlords have faced rising costs in recent years, including higher mortgage rates, stricter tax rules, and increasing maintenance expenses.
The removal of mortgage interest tax relief through Section 24 changes has already reduced profitability for many buy-to-let investors, particularly those with mortgages.
At the same time, landlords are also preparing for stricter regulations under the Renters’ Rights Act, which has introduced major changes to tenancy rules and tenant protections.
There are also concerns around proposed energy efficiency requirements, including future EPC targets that may require expensive upgrades to older properties.
For smaller landlords in particular, these combined pressures are leading some to question whether property investment remains worthwhile.
Government insists the sector is expanding
Despite the decline in rental stock shown by the latest research, the government continues to defend its position that the private rented sector remains strong.
A spokesperson from the Ministry of Housing, Communities and Local Government said that the sector has doubled in size since the early 2000s.
The government also argues that the Renters’ Rights Act will improve conditions for tenants by providing stronger protections and greater security.
Among the measures included in the legislation are stronger powers for tenants to challenge above-market rent increases, as well as the abolition of Section 21 no-fault evictions.
Ministers say these reforms are intended to create a fairer and more stable rental market for millions of renters across England.
Concerns over the long-term impact
However, many property professionals remain concerned about the long-term effect these policies could have on rental supply.
Industry figures have repeatedly warned that increasing regulation and financial pressure may encourage more landlords to sell their properties rather than continue renting them out.
Lucian Cook said the market is likely to see additional landlord exits in the months ahead, although he suggested the sector may be nearing the peak of the current sell-off.
Even if the pace of landlord exits slows, many experts believe rental supply will remain tight for some time.
Rental shortages continue to affect tenants
The reduction in available rental homes is becoming an increasing issue for tenants across many parts of the UK.
When supply falls but demand remains high, competition between renters intensifies. This can lead to longer property searches, bidding wars, and rising rents.
In major cities such as London, Manchester, and Birmingham, demand for rental housing continues to significantly exceed available stock.
Many tenants are already finding it harder to secure suitable accommodation, particularly in areas where affordability is already stretched.
While the government’s reforms are designed to improve tenant protections, critics argue that reducing landlord confidence could ultimately make it more difficult for renters to find homes in the first place.
The growing divide in the housing debate
The latest figures reflect a wider debate taking place across the UK housing market.
Supporters of the Renters’ Rights Act argue that stronger regulation is necessary to improve standards and provide tenants with greater stability.
On the other hand, many landlords and industry groups believe the pace of regulatory change is placing too much pressure on the private rented sector at a time when supply is already under strain.
There are also concerns that rising compliance costs may favour larger institutional landlords while smaller independent landlords gradually leave the market.
This could fundamentally reshape the structure of the UK rental sector over the coming years.
What happens next?
The next 12 to 24 months may prove crucial for the future of the private rented sector.
Much will depend on how landlords respond to the latest reforms, whether mortgage rates begin to ease, and how future housing policies are implemented.
If rental supply continues to fall while demand remains high, affordability pressures for tenants could intensify even further.
At the same time, the government will face growing scrutiny over whether its housing reforms are achieving the intended balance between protecting tenants and maintaining enough rental supply across the country.
For now, the latest research suggests that, despite official claims of growth, the private rented sector is continuing to shrink in many areas of the UK.
