When to use this template
Use this letter when you are a landlord or tenant and wish to formally acknowledge, in writing, that a fixed-term assured shorthold tenancy has transitioned to a periodic assured tenancy under the Renters' Rights Act 2025. It confirms the new statutory framework and updated rights and responsibilities for both parties. Useful at the commencement of the transition to avoid disputes.
When NOT to use this template
Do not use if the tenancy is excluded from the Renters' Rights Act 2025 (e.g. Crown tenancies, certain student lettings, tenancies at very high rents). Do not use as a notice to quit or as a replacement for a Section 8 notice. Do not use if the tenancy commenced after the Act's commencement date — in that case it will be a periodic assured tenancy from the start.
Legal Basis
Renters' Rights Act 2025 (UK), abolishing assured shorthold tenancies and converting existing ASTs to periodic assured tenancies. The Act also restricts rent increases to once per year (via s.13 Housing Act 1988 procedure), abolishes 'no-fault' eviction under former s.21 Housing Act 1988, and introduces new mandatory and discretionary grounds for possession (as amended by the 2025 Act).
Before you send
- Serving a Section 21 notice after the Act's commencement date — s.21 is abolished; the notice will be invalid
- Attempting to impose a new fixed term — the tenancy is now periodic by statute and cannot revert to a fixed term
- Increasing rent more than once per 12 months or by more than what can be referred to the Tribunal — process must follow s.13 HA 1988

[YOUR FULL NAME (LANDLORD OR TENANT)] [YOUR ADDRESS] [YOUR EMAIL ADDRESS] [DATE OF LETTER] [RECIPIENT'S FULL NAME] [RECIPIENT'S ADDRESS] --- Dear [SALUTATION], **Re: Tenancy at [FULL ADDRESS OF THE RENTED PROPERTY] — Renters' Rights Act 2025 Transition** I am writing in connection with the tenancy of the above property, which was originally granted as an assured shorthold tenancy commencing on **[DATE THE ORIGINAL TENANCY BEGAN]** [ORIGINAL FIXED TERM DETAILS (E.G. 'FOR A FIXED TERM OF 12 MONTHS ENDING 31 MARCH 2026')]. **Transition to Periodic Assured Tenancy** The Renters' Rights Act 2025 has now come into force. As a result, and in accordance with the transitional provisions of the Act, the tenancy of the above property has automatically converted to a **periodic assured tenancy**, with a rental period of one month. No action is required by either party to effect this conversion; it has occurred by operation of law. **Key Changes under the New Framework** The following key changes now apply to this tenancy: 1. **Security of tenure:** The tenancy continues on a periodic basis until lawfully ended by the landlord serving a valid notice under one of the grounds for possession set out in Schedule 2 to the Housing Act 1988 (as amended by the 2025 Act). The former 'no-fault' Ground (Section 21) has been abolished. 2. **Rent increases:** Rent may only be increased once in any 12-month period, using the statutory process under Section 13 of the Housing Act 1988. Any proposed increase must be notified using Form 4 and the tenant has the right to refer the proposed increase to the First-tier Tribunal (Property Chamber). 3. **Tenant's rights:** You continue to enjoy all the rights you held as an assured shorthold tenant, together with the enhanced rights conferred by the Renters' Rights Act 2025, including the right to keep a pet (subject to reasonable conditions) and protection against retaliatory eviction. 4. **Landlord's obligations:** The landlord remains obliged to maintain the property in good repair, comply with gas and electrical safety obligations, maintain the energy performance certificate, and comply with all applicable licensing requirements. **Continuity** All other terms of the original tenancy agreement (including rent, tenant obligations, and deposit arrangements) remain in full force and effect, save as modified by the Renters' Rights Act 2025 or other applicable legislation. **Questions** If you have any questions about this letter or the effect of the Renters' Rights Act 2025 on your tenancy, please do not hesitate to contact me. Both parties are encouraged to seek independent advice from a housing adviser, Citizens Advice, or Shelter if needed. Yours sincerely, [YOUR FULL NAME (LANDLORD OR TENANT)]
