Why the rise in guarantor-tenancies signals change ahead for UK buy-to-let portfolios
What’s Changing in the Rental Landscape
The UK’s private rented sector is shifting. With the Renters’ Rights Bill moving through Parliament, landlords and agents are bracing for tighter regulations — from the abolition of Section 21 ‘no-fault’ evictions to stronger tenancy protections.
A key early signal of adjustment: the sharp rise in tenancies that now require a guarantor. According to The Negotiator, guarantor-tenancies have surged by nearly 18% year-on-year and more than 30% compared with 2023. Meanwhile, the English Private Landlord Survey 2024 (EPLS) found that more than half of landlords now use either a guarantor or advance rent for their latest letting.
This isn’t just a short-term precaution — it reflects deeper shifts in how landlords assess tenant risk, structure tenancies, and plan for future income stability.
Why Are More Landlords Requesting Guarantors?
a) Regulatory and legal uncertainty
The Renters’ Rights Bill proposes to abolish Section 21 evictions and strengthen tenants’ rights to longer occupancy. While the aim is greater fairness and security, it also means landlords face longer timeframes to regain possession in cases of rent arrears or anti-social behaviour.
Letting agents interviewed by The Negotiator note that many landlords are responding pre-emptively — adding guarantor clauses to mitigate potential delays or losses in future possession disputes.
b) Economic pressures on tenants
Persistent inflation, elevated mortgage rates and high living costs have increased the likelihood of late or missed rent payments. A guarantor arrangement provides an additional safeguard against arrears, especially as cost-of-living challenges continue to squeeze disposable incomes.
c) Shift in landlord risk management
The EPLS 2024 reported that 14% of landlords asked for a guarantor and 7% requested both rent in advance and a guarantor. This shift indicates a growing perception of tenant-risk, with landlords building more robust screening into tenancy agreements.
Implications for Buy-to-Let, Supported Living, and Social Housing Investors
a) Underwriting and finance
Buy-to-let lenders and brokers may begin factoring guarantor trends into underwriting. Investors could see greater emphasis on tenant affordability and repayment guarantees when assessing mortgage eligibility.
b) Tenant accessibility
While guarantors offer financial protection, they can also narrow the tenant pool — particularly among younger renters or those without family support networks. For supported living or social housing providers, where tenants may not have access to guarantors, this trend could complicate allocations unless offset by alternative measures such as rent-guarantee insurance or service-level partnerships.
c) Portfolio resilience and exits
The EPLS 2024 found that 31% of landlords plan to reduce their portfolios within two years — up from 22% in 2021. Combined with concerns about future regulation, this suggests rising caution and potential supply tightening.
In fact, Landlord Zone warns that the Renters’ Rights Bill could trigger a “landlord exodus,” particularly among smaller investors who struggle with compliance costs.
How Investors Should Respond
Reassess tenant-vetting frameworks — Review how guarantor requirements interact with your rent-arrears policy, tenancy agreements, and insurance coverage.
Plan for longer holding periods — The removal of Section 21 will likely mean slower exits; ensure cashflow models account for longer notice and recovery timelines.
Explore specialist tenancy models — For supported-living or social-housing investors, consider long-term lease partnerships with care providers or housing associations that guarantee rent directly.
Factor compliance into ROI — Administrative, legal and management overheads will rise. Revisit yield projections to maintain realistic returns under a stricter regime.
Monitor secondary-market shifts — If smaller landlords do exit, larger or institutional investors may find acquisition opportunities — but due diligence and EPC alignment remain key.
Policy Link and Outlook
The Guide to the Renters’ Rights Bill confirms its intent to rebalance power between tenants and landlords — yet as seen in the EPLS 2024, the resulting uncertainty is already shaping market behaviour.
While increased guarantor-use may offer reassurance to landlords, it also highlights a transitional moment: one in which the PRS must evolve toward more formalised risk management, better tenant engagement, and sustainable portfolio models.
For buy-to-let and supported-living investors, recognising these signals early — and adapting business structures accordingly — will be essential to maintaining both compliance and resilience in a changing regulatory climate.
