Landlord confidence and the shrinking private rented sector

Property118 has highlighted a concerning trend: the private rented sector in the UK is contracting as landlords lose confidence and exit the market. According to Property118’s founder, landlord confidence is not an abstract idea but the essential driver that sustains rental supply. When confidence diminishes, fewer landlords participate, leading to tighter supply, rising rents, and reduced choice for tenants.

In this context, Property118 has openly criticised Shelter, a major housing charity, for campaigning in ways that have contributed to political conditions prompting landlords to leave the sector. The founder stated, “Shelter has been highly effective at influencing policymakers. The unintended consequence is that many landlords no longer see the sector as commercially sustainable. When landlords exit, the supply of rental housing falls. That inevitably drives rents higher and makes life harder for tenants.”

Understanding the landlord exodus in practice

The term “landlord exodus” may sound abstract, but Property118 explains it through real-world examples. Portfolio landlords often sell properties at tenancy end not out of desire but because the investment no longer meets their risk and return expectations. Long-standing landlords may avoid remortgaging due to higher rates, stricter affordability checks, and increasing compliance demands. Others who would have expanded their portfolios in previous years now choose to reduce leverage or leave the sector entirely.

Property118 has repeatedly reported on this trend, including landlords exiting quickly while still achieving strong sale prices, which can accelerate decisions to leave. The platform has also documented the interplay of rising costs, legislation, and operational challenges that contribute to declining landlord confidence.

Crucially, most landlords exit incrementally rather than abruptly, meaning the sector can shrink over several years before political recognition of the issue. By then, rents have often risen, and reversing supply loss becomes difficult. This trend has reached parliamentary debate, with concerns raised about landlords “voting with their feet” amid new tenancy legislation.

Institutional investors and the significance of John Lewis’s withdrawal

For some time, it was assumed that institutional investors and build-to-rent developments would fill gaps left by individual landlords. However, the John Lewis Partnership’s recent decision to exit its build-to-rent ambitions has challenged this assumption. Property118 reported that John Lewis cited higher borrowing and construction costs, alongside a changed market environment, as reasons for retreating.

This development is significant because institutional investors typically base decisions on commercial viability rather than sentiment. The founder of Property118 remarked, “When a major institutional investor enters the sector with long-term ambitions and then withdraws after assessing the commercial realities, it reinforces what private landlords have been experiencing for years. This is not about sentiment. It is about viability.”

While build-to-rent remains part of the housing mix, John Lewis’s withdrawal raises urgent questions about whether it can scale sufficiently and at appropriate price points to offset supply lost through landlord exits.

Shelter’s campaigning and the issue of supply accountability

Property118’s critique of Shelter centres on the charity’s role in shaping a political narrative that frames landlords primarily as a problem to be constrained, rather than as essential providers of housing. Shelter, a well-funded national charity, focuses on tenant protection through campaigning and policy advocacy but does not build or provide housing at scale.

The concern is that campaigning which emphasises constraints on landlords without acknowledging supply consequences weakens incentives for landlords to remain in the sector. Property118’s founder explained, “Shelter’s objectives are framed around protecting tenants. The difficulty is that policies which discourage landlords from providing housing ultimately reduce supply. The result is fewer homes and higher rents.”

While stronger regulation to improve standards and protect renters is widely supported, the combination of regulation, tax, and political messaging can reduce landlord participation. This contraction in supply leads to increased competition among tenants, higher rents, and fewer choices—outcomes driven by market mechanics rather than ideology.

Legislative uncertainty and its impact on rental supply

The Renters’ Rights Act represents a major shift in the private rented sector, altering risks, enforcement, and tenancy structures. However, the UK government has admitted it did not conduct an impact assessment on how key elements of the Act might affect rental supply. Property118 has highlighted this admission as central to the problem, warning that reforms designed without supply impact modelling risk unintended negative outcomes for tenants.

Additional challenges include court preparedness and extended waiting times, which further complicate enforcement and operational realities. Property118 emphasises that the sector requires not just new rules but predictable enforcement, workable processes, and policies that reflect how landlords make decisions. Stability and clarity in the legislative framework are essential to maintaining landlord participation.

Political volatility also threatens supply. Reform UK has pledged to scrap the Renters’ Rights Act, signalling ongoing uncertainty. Property118’s founder noted, “Housing investment depends on stability. When the legislative framework becomes uncertain or politically contested, landlords pause or withdraw. That inevitably tightens supply.”

Consequences for tenants: reduced choice and increased rents

As the private rented sector contracts, tenants experience the effects first. Social housing is not expanding quickly enough, and owner-occupation remains out of reach for many, making the private rented sector the critical “pressure valve.” When this valve tightens, tenants face competitive viewings, rushed decisions, compromises on location and condition, and reduced mobility.

Property118 has also drawn attention to international examples where anti-landlord policies triggered exits and subsequent policy reversals, highlighting the risks of ignoring supply dynamics.

The platform stresses that tenant protection and rental supply are interconnected objectives. Improving standards requires enforcement against rogue landlords and support for professionalism, but maintaining stable rents and choice also demands conditions that encourage landlords and institutions to provide homes.

Property118’s call for supply accountability in housing policy

Property118 advocates for recognition that rental supply is not automatic but the result of commercial decisions by landlords and institutions. When these decisions become negative, rental housing disappears or reappears under less favourable conditions, often at higher rents or different ownership models.

The founder urged Shelter to acknowledge the consequences of campaigning that pushes policy in one direction without considering supply effects: “This is not about defending landlords. It is about protecting tenants from the predictable consequences of shrinking supply. If we keep reducing participation, we will keep increasing rents and instability.”

Property118 will continue to report on landlord exits, institutional investment changes, and the impacts of legislation as they unfold, emphasising that policymakers and campaigners must anticipate outcomes rather than be surprised by them. For tenants, the priority remains clear: more homes, more choice, and greater stability.

Supporting independent landlord-focused reporting

Property118 operates as an independent platform providing open, commercially grounded reporting on the private rented sector, free of paywalls and political sponsorship. Its articles reach millions monthly, serving landlords, tenants, journalists, lenders, and policymakers seeking clarity on housing supply issues.

The platform invites support from landlords to maintain its independence and continue delivering evidence-led analysis without compromise.
