Rent Increase Notice (Form 4A) — landlord obligations in England
If you want to increase the rent for an assured periodic tenancy, you must serve a valid notice using Form 4A. You can only increase rent once every 12 months, and the notice period must be at least 2 months. This applies to notices served on or after 1 May 2026.
