The Renters’ Rights Act 2025 came into force in its first phase on 1 May 2026, and it represents the most significant change to the private rented sector in England for a generation. The abolition of Section 21 no-fault evictions, the end of fixed-term assured shorthold tenancies and the introduction of a new assured periodic tenancy structure have fundamentally altered the legal framework that underpins every buy-to-let investment in England.

For property investors acquiring residential property in 2026, understanding the implications of these changes — and how they affect the pre-acquisition review process — is now a core part of informed investment decision-making.

The End of Section 21 and What Replaces It

Section 21 of the Housing Act 1988 previously allowed landlords to recover possession of a property let on an assured shorthold tenancy by serving two months’ written notice, without needing to establish any ground for possession. This is now abolished for all tenancies in England that fall within the Act’s scope.

Under the new framework, landlords wishing to recover possession must establish one of the statutory grounds for possession set out in Schedule 2 to the Act (as amended). Key grounds that remain available to investors include:

  • Ground 1 — the landlord (or a family member) intends to occupy the property as their only or principal home.
  • Ground 1A — the landlord intends to sell the property.
  • Ground 8 — the tenant has rent arrears of at least two months (or eight weeks) at both the time of service and the hearing.
  • Ground 14 — the tenant is causing nuisance or antisocial behaviour.

Where a landlord wishes to sell a tenanted property, the new Ground 1A is now the appropriate legal mechanism. However, it requires a period of notice (currently four months for new tenancies) and cannot be used until the tenancy has been in existence for a specified period. This has important implications for investors acquiring tenanted properties with the intention of selling with vacant possession.

What This Means for Tenanted Acquisition

For investors acquiring a property that is already let to tenants, the changed possession framework means that the route to vacant possession has changed materially. Buyers should assess:

  • The current tenancy structure — whether tenants are in the first year of a new tenancy (during which certain grounds are not available) or in a more established periodic tenancy.
  • Whether the intended strategy requires vacant possession and, if so, on what timeline and through which legal ground.
  • Rent arrears position — whether any existing arrears are sufficient to support a Ground 8 claim, and whether a new owner would want to pursue that route.
  • The notice periods applicable to the relevant ground — which in some cases are longer under the new legislation than under the previous regime.

An investment strategy that previously relied on the straightforward exercise of a Section 21 notice — buying a tenanted property with the intention of quickly achieving vacant possession — will need to be reassessed against the new possession grounds.

New Tenancy Structure: No More Fixed Terms

The Act abolishes fixed-term assured shorthold tenancies for new tenancies granted from 1 May 2026. All new tenancies are automatically periodic — typically monthly — from the outset. This means there is no fixed-term minimum, and tenants can give two months’ notice to leave at any point (subject to any restrictions in the early months of the tenancy under the legislation).

For investors, this changes the character of what is being acquired when a tenanted property changes hands. There are no fixed-term protections creating certainty of occupation through to a set date — tenants can leave more easily, and the void management picture therefore needs to be considered in yield forecasts.

Implications for Buy-to-Let Strategy

The new possession framework does not make buy-to-let investment unworkable. Millions of tenancies operate entirely without possession proceedings, and the rental market remains structurally undersupplied relative to tenant demand. But the changed legal landscape does require investors to think more carefully about:

  • Tenant selection and references — with possession proceedings now more involved and time-consuming, selecting tenants carefully is more important than before.
  • Property management quality — well-managed properties with good tenant relationships are less likely to generate possession proceedings in the first place.
  • Exit strategy — where sale with vacant possession is part of the investment plan, the timeline and legal route need to be mapped out before acquisition, not after.
  • Pricing of tenanted properties — where a property is being sold with sitting tenants, the complexity of achieving vacant possession under the new framework may justify a price adjustment relative to the vacant possession value.

For investors reviewing a legal pack on a tenanted property in 2026, the tenancy-related documents are now more important than ever. Key items to look for include:

  • Current tenancy agreements — confirming the date of grant, the current rent, and the tenancy type.
  • Rent arrears — any history of arrears and the current position.
  • Prior notices served — whether any possession notices have been served and what stage any proceedings have reached.
  • Deposit protection compliance — whether tenants’ deposits have been protected in a government-approved scheme within the required timeframe, and whether prescribed information has been served. Non-compliance is a bar to certain possession claims.
  • HMO-related documentation — where the property is an HMO, the tenancy structure and compliance position are both relevant.
