Renters’ Rights Act 2025: what landlords must do before May 2026

The Renters’ Rights Act 2025 is expected to bring major changes to the private rented sector in England from 1 May 2026. For buy-to-let landlords, the impact is likely to be felt in three areas: how tenancies end, how rent increases are handled, and how possession for arrears may work in practice.

This article focuses on practical implications for landlords and preparation points that can help reduce avoidable disruption as the new framework beds in.

Key changes coming in from 1 May 2026

1) Section 21 is abolished (no more “no-fault” evictions)

From 1 May 2026, landlords will no longer be able to use Section 21 to regain possession without relying on a specific reason.

In practical terms, possession will need to be pursued under the Section 8 route (ground-based possession). That shift matters because it changes how landlords plan:

• Exit timing: strategies that previously depended on Section 21 notice periods may need to be reworked.
• Documentation and process: grounds-based possession typically requires careful attention to the legal basis and evidence.
• Tenancy expectations: landlords may need to manage tenant relationships with a longer-term view, since “resetting” a tenancy timeline may be harder.

2) Tenancies move towards a more uniform rolling model

The Act is expected to change how tenancies operate in practice. Landlords should expect a move away from the previous fixed-term/notice-driven approach and towards rolling periodic tenancies.

For landlords, this can affect:

• How and when changes can be made
• Planning for sale or re-let
• The administrative rhythm of managing tenancies year to year

3) Rent increases face more structure and more opportunities to challenge

The Act introduces a more formalised approach to rent increases, including tighter timing and process requirements.

A key practical risk for landlords is cash flow timing. If a tenant challenges a rent increase through the relevant tribunal process, the higher rent may not apply until the dispute is resolved. That can mean:

• Longer periods at the previous rent level
• Affordability pressure if mortgage costs rise or if rental income is expected to increase to maintain coverage

For buy-to-let investors, this is especially relevant when rent increases are part of the financial plan to support:

• Interest rate changes
• Refinancing assumptions
• Ongoing servicing costs (insurance, maintenance, and service charges where applicable)

4) Possession for rent arrears becomes more demanding

The Act is expected to make eviction for non-payment more restrictive. While the detail can vary by circumstance, the direction of travel is that landlords may face higher thresholds and longer lead times before possession for arrears can be pursued.

From a portfolio perspective, this can increase exposure to:

• Periods of reduced or no rent
• Longer arrears management cycles
• Greater importance of early intervention

Important dates landlords should be aware of

While landlords should always check the latest official guidance and their own circumstances, the following dates are commonly referenced in the run-up to the changes:

• 30 April 2026: the final day to serve a Section 21 notice (where applicable)
• 1 May 2026: the new framework takes effect, including the abolition of Section 21
• 31 May 2026: a deadline for providing tenants with the government information sheet about the new rules

Missing a deadline can create complications, so it’s worth treating these dates as part of a wider compliance timetable rather than isolated tasks.

What this means for buy-to-let landlords’ mortgage planning

The Renters’ Rights Act 2025 is not only a legal change—it can influence the financial assumptions many landlords use when planning refinancing and long-term portfolio performance.

Cash flow and stress-testing

If rent increases are delayed by tribunal challenges, or if arrears take longer to resolve, landlords may need to ensure their rental income projections remain realistic under less favourable timing.

A practical approach is to stress-test scenarios such as:

• rent increases not landing when expected
• temporary shortfalls due to arrears
• extended voids or delays in regaining possession

Refinance timing and product suitability

Landlords may also want to consider whether their current mortgage arrangements align with the new operating environment—particularly if a product ends around the changeover period.

Even where lenders’ criteria are not directly “changed” because of the Act, the way lenders assess risk can be influenced by how rental income and possession outcomes may behave under the new rules.

Portfolio structure and operational readiness

Some landlords may review how they manage tenancies and whether their portfolio approach is resilient to a more complex regulatory environment.

That can include reviewing:

• tenancy management processes
• arrears monitoring and escalation routines
• how rent review plans are documented and communicated

Preparation steps landlords can consider now

The most useful preparation is often practical: ensuring the landlord’s processes, records and plans are ready for a world where “resetting” tenancies is less straightforward.

Review tenancy strategy and exit planning

With Section 21 no longer available, landlords may need to revisit how they plan:

• when a property might be sold
• when a landlord intends to move back in
• when a property might be re-let after a tenant leaves

Tighten rent increase planning

Because rent increases may be more contestable, landlords should ensure rent increase decisions are supported by clear evidence and that the process is followed carefully.

This can help reduce avoidable disputes and the risk of income delays.

Strengthen arrears prevention and early action

Given the increased friction around arrears-based possession, early intervention becomes more important. Landlords may want to ensure they have a consistent approach to:

• identifying arrears early
• communicating clearly with tenants
• documenting steps taken

Check compliance processes and deadlines

The May 2026 changes come with specific timing requirements. Landlords can reduce risk by building a simple internal timetable that covers:

• notice and tenancy documentation
• tenant information requirements
• any planned rent increase activity

The bigger picture

The Renters’ Rights Act 2025 is designed to strengthen tenant protections and make the private rented sector more consistent and predictable. For landlords, that typically means less flexibility and more process discipline.

For buy-to-let investors, the opportunity is in adapting early: aligning tenancy management, cash flow planning and mortgage strategy with the new operating reality.

Related considerations for landlords

Landlords often find it helpful to review other areas that commonly intersect with regulatory change, such as:

• how refinancing assumptions are built into portfolio plans
• whether portfolio structure supports long-term resilience
• how lender assessments may react to changes in rental income stability

If you’re planning around the May 2026 transition, the most effective preparation is usually a combination of legal awareness, operational readiness, and financial stress-testing.
