Property118 is publishing this analysis because the private rented sector is shrinking in plain sight, and the people who pay the price first are tenants.

Property118 has long argued that landlord confidence is not an abstract concept; it is the fuel that keeps rental supply flowing. Remove confidence and participation falls. When participation falls, supply tightens, rents rise, and choice disappears.

Against that backdrop, Property118’s founder has criticised Shelter for campaigning in a way that, in Property118’s view, has helped create the political conditions for a landlord exodus.

“Shelter has been highly effective at influencing policymakers,” he said. “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.”

What the landlord exodus looks like in practice

“Landlord exodus” can sound like a slogan until you see how it plays out on the ground.

It is the portfolio landlord who sells one house each time a tenancy ends, not because they want to leave, but because keeping the property no longer meets their risk and return requirements.

It is the long-standing landlord who decides not to re-mortgage, because the next product comes with higher rates, stricter affordability, and a compliance burden that feels unending.

It is the landlord who would have bought again five years ago, but now chooses to de-lever, simplify, or step away entirely.

Property118 has covered this trend repeatedly. Recent examples include commentary on landlords exiting under regulatory pressure and still achieving strong sale prices, which often accelerates decision-making because the exit route appears commercially attractive. See: landlords exiting in under 28 days.

Property118 has also reported on broader indicators of declining confidence, including the interaction between rising costs, legislation and the practical strain of running rental homes to an ever-tightening standard. See: landlord confidence plummets amid soaring costs and new legislation.

Why John Lewis matters, and why it changed the argument overnight

For years, the default response to concerns about landlord exits has been to suggest that institutional capital will simply replace individual landlords. The theory is that build-to-rent will scale up and fill the gap.

Then came John Lewis.

The John Lewis Partnership announced a high-profile entry into build-to-rent, with ambitious plans that were widely interpreted as a sign of confidence in long-term rental housing. It carried the authority of a trusted national brand and the financial weight of an institution that plans in decades.

Property118 has now reported that John Lewis is exiting those build-to-rent ambitions, citing the commercial reality of higher borrowing and construction costs, and a changed market environment. See: John Lewis exits build-to-rent housing projects.

This matters because institutional investors do not leave the sector due to emotion. They leave when the numbers no longer work.

Property118’s view is straightforward. If a well-capitalised institution reassesses and retreats, it becomes far harder to dismiss the warnings coming from smaller landlords, letting agents and lenders.

“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,” Property118’s founder said. “This is not about sentiment. It is about viability.”

Shelter’s influence, and the problem with campaigning without supply accountability

Property118 is directly critical of Shelter for one central reason. In Property118’s view, Shelter has been a leading force in pushing a political narrative that frames landlords primarily as a problem to be constrained, rather than as participants who must remain willing to provide housing if supply is to hold up.

Shelter is a major national charity with significant financial resources, receiving income from donations and grants that runs into many millions of pounds each year. Its work includes campaigning, policy advocacy, and the provision of advice and support services. It does not, however, build or provide housing at scale.

Property118’s concern is not that Shelter campaigns, it is that the campaigning environment has become disconnected from supply accountability. The louder the pressure to constrain landlords becomes, the weaker the incentive becomes to stay in the sector and maintain rental homes.

Property118 has previously reported on Shelter’s public commentary around rising rents and the temporary accommodation crisis, alongside warnings from industry bodies about landlord exits. See: Shelter blames rising rents as NRLA warns of landlord exodus.

“Shelter’s objectives are framed around protecting tenants,” Property118’s founder said. “The difficulty is that policies which discourage landlords from providing housing ultimately reduce supply. The result is fewer homes and higher rents.”

Renters’ Rights Act uncertainty, and a government that admits it did not assess supply impact

The Renters’ Rights Act represents one of the most significant shifts in the private rented sector for a generation. It changes the practical balance of risk, enforcement, and certainty around possession and tenancy structures.

What is astonishing, and now firmly in the public domain, is that the government has admitted it did not carry out an impact assessment on how key elements of the Renters’ Rights Act might affect rental supply.

Property118 has reported this directly, including the written question that triggered the admission. See: government admits no impact assessment of Renters’ Rights Act on supply.

For Property118, this is not a procedural footnote. It is the heart of the problem.

If government does not model the impact on supply, it risks designing reforms that feel morally satisfying but deliver worse outcomes, especially for the renters they aim to protect.

Property118 has also reported on related issues around readiness and capacity, including claims about court preparedness, and the reality of extended waiting times. See: government claims courts will be ready for Renters’ Rights Act.

Reform UK’s pledge to scrap the Renters’ Rights Act shows how politically fragile the framework has become

Legislation that reshapes a market should ideally settle into place and remain stable for years. The private rented sector relies on long-term commitments; mortgage terms, refurbishment cycles and portfolio planning all operate on multi-year horizons.

Instead, the Renters’ Rights Act is already politically contested, with Reform UK signalling an intention to repeal it.

Property118 has published commentary on this point and its implications for confidence and supply. See: Property118 analysis on Reform UK and the Renters’ Rights Act.

For Property118, the key issue is not which party is right. It is what this level of political volatility does to supply.

Landlords and institutional investors watch signals. If they believe the rules may change again, they delay investment, reduce exposure, or exit. That does not require a conspiracy, just rational decision-making.

The consequence tenants feel first: less choice, higher rents, and reduced mobility

It is tempting for campaigners to talk about landlords as though they are optional, but the housing system does not work that way.

Social housing is not expanding fast enough to meet need. Owner-occupation remains inaccessible for many. The private rented sector is the pressure valve, and it only functions when enough people are willing to provide homes to rent. When the pressure valve tightens, tenants feel it. Not in theory, but in daily life.

Viewings become competitive, tenants make rushed decisions, families accept compromises on location, size and condition. People stay put because moving is too hard, even when work, school or family life would benefit from flexibility.

Property118 has also explored the wider directional risks, including international policy reversals where governments tightened rules, triggered exits, then scrambled to reverse course. See: anti-landlord policy U-turns abroad spark warnings for the UK.

Property118’s position: stop pretending supply is automatic

Property118 is not asking for a return to the past, the sector has moved on, and standards have risen and must continue to rise.

Property118 is asking for a policy approach that accepts one basic truth; rental supply is not automatic. It is the product of commercial decisions made by individuals and institutions over many years. When those decisions turn negative, rental housing disappears. It may reappear later, but often at a higher rent level, or in a different ownership model, or not at all.

That is why Property118 believes Shelter must take responsibility for the consequences of campaigning that pushes policy in one direction without acknowledging supply effects.

“This is not about defending landlords,” Property118’s founder said. “It is about protecting tenants from the predictable consequences of shrinking supply. If we keep reducing participation, we will keep increasing rents and instability.”

Why Property118 continues to publish this reporting

Property118 exists to report openly on developments affecting landlords, tenants, and the housing market. Property118 does not operate behind a paywall. Property118 does not restrict access to its reporting. Property118 remains free to read because access to accurate information protects landlords from costly mistakes and helps maintain confidence in the sector.

Property118 articles now appear in more than 3,000,000 Google search impressions each month. That reach exists because landlords, lenders, journalists and policymakers rely on Property118 as a primary source of commercially grounded reporting on the private rented sector.

Maintaining that independence requires ongoing support. Property118 receives no government funding and does not rely on political sponsorship. Its independence allows Property118 to publish evidence-led analysis without compromise.
