When to use this template

Form 4A is the statutory notice you must use to propose a new rent on a periodic assured tenancy. From commencement of the Renters' Rights Act 2025, every assured tenancy is periodic by default — so this is now the only valid mechanism for raising rent on existing tenancies.

Key rules to follow

  • Rent can be increased no more than once in every 52-week period (HA 1988 s.13(2)(b)(ii), as amended by RRA 2025 s.6).
  • Notice period is at least two months before the new rent takes effect.
  • The proposed rent must be the open market rent — the Tribunal will refuse increases that exceed it.
  • Tenant has the right to challenge by applying to the First-tier Tribunal (Property Chamber).
  • Use the same wording GOV.UK publishes — Tribunal applications can be rejected on form-defect grounds.

What's in the template

  1. Tenant + landlord party block
  2. Notice of new rent + the date it takes effect
  3. Notice period statement (≥ 2 months)
  4. Right-to-challenge text + Tribunal application instructions
  5. Frequency + open-market-rent caveat
