Overview
Assured shorthold tenancies were for many years the standard form of private residential tenancy in England, but the legal landscape has now changed materially. Since 1 May 2026, the private rented sector has moved away from fixed-term assured shorthold tenancies to a periodic assured tenancy model, with section 21 abolished and landlords required to rely on statutory grounds for possession. This affects landlords, tenants, letting agents and investors, particularly where disputes arise over tenancy status, notice validity, rent increases or legacy tenancy documents. Early legal advice is important because many disputes turn on whether a tenancy is governed by the historic AST regime or the new periodic system, and getting that wrong can lead to failed possession claims, unnecessary cost and avoidable delay. Alstern Solicitors assists clients with tenancy audits, possession strategy and dispute resolution planning.
Key Legal Principles
- Historically, private residential tenancies were often granted as assured shorthold tenancies under Housing Act 1988.
- Under Housing Act 1988, if a fixed term ended and the tenant remained in occupation, a statutory periodic tenancy could arise automatically.
- In Superstrike Ltd v Rodrigues [2013] EWCA Civ 669, [2013] 1 WLR 3848, the Court of Appeal confirmed the significance of that statutory periodic tenancy for deposit compliance purposes.
- From 1 May 2026, all assured tenancies are periodic and no new fixed terms may be created within the assured tenancy system in England.
- Existing fixed terms automatically convert into rolling tenancies from that date, and any contractual end date ceases to determine the tenancy’s end.
- Tenants may usually end the tenancy by giving two months’ notice.
- Landlords can recover possession only by relying on statutory grounds, not by using section 21.
- Rent review clauses in existing tenancy agreements no longer govern increases after 1 May 2026; landlords must instead use the Housing Act 1988, s 13 process, with written notice and ordinarily no more than one increase per year.
- A tenant can challenge a proposed increase in the First-tier Tribunal under that statutory process.
Practical point: many current disputes are not really about “AST law” in the abstract; they are about whether a historic AST has now become a periodic assured tenancy and what that means for possession, rent, and compliance.
What Evidence Is Usually Required?
- The signed tenancy agreement and any renewals or memoranda.
- A chronology showing when the fixed term began and ended.
- Rent statements and records of any increases proposed or agreed.
- Notices served by either party and proof of service.
- Deposit records, especially where a fixed term rolled into a periodic tenancy.
- Communications about surrender, arrears, repairs or renewal discussions.
What Are the Available Options?
- Informal negotiation
- Solicitor correspondence
- Mediation / ADR
- Tribunal or court action
- Compliance audit
The above information is intended for general guidance only. Every dispute involves different legal and factual circumstances. Early legal assessment, evidence review and strategic planning are often critical to achieving a successful outcome. Contact Alstern Solicitors for advice tailored to your specific circumstances.
Common Risks or Mistakes
- Assuming the phrase “AST” still answers the legal question in every case.
- Missing the change from fixed term to periodic status.
- Relying on outdated tenancy clauses for rent review.
- Failing to review historic deposit compliance when the tenancy rolled over.
- Delaying advice until after an invalid notice has been served.
- These mistakes can weaken a claim or defence, increase costs, and cause substantial delay.
Case Study from Alstern Solicitors
Background
A landlord held a portfolio of older tenancy agreements described as assured shorthold tenancies, several of which had begun as fixed terms years earlier.
Challenge
The landlord wanted possession of one property and believed the tenancy had simply “ended”, but the papers showed a legacy fixed term followed by ongoing occupation and inconsistent rent documentation.
How We Assisted the Client
Alstern Solicitors reviewed the tenancy history, identified the current status of the tenancy, assessed the effect of the post-1 May 2026 reforms, and advised on the safest possession and negotiation strategy.
Outcome
The client avoided issuing defective proceedings and resolved the matter on a clearer legal footing, reducing delay and unnecessary cost.
What Happens If You Choose the Wrong or Inexperienced Solicitor?
An inexperienced adviser may focus on old AST labels rather than the current statutory position, miss the periodic status of the tenancy, overlook deposit problems, or pursue an invalid possession route. That can lead to adjourned or dismissed claims, wasted costs and lost settlement opportunities.
