Frequently asked questions
- What is a Section 13 notice?
- A Section 13 notice is the legal mechanism landlords must use to increase rent on assured periodic tenancies in England. It requires a prescribed form (now Form 4A) and must give the tenant at least two months' notice. The tenant can refer the proposed increase to the First-tier Tribunal if they disagree.
- What is Form 4A and why do I need it instead of Form 4?
- Form 4A (version 05.26) replaced Form 4 when the Renters' Rights Act 2025 commenced on 1 May 2026. Form 4 is now only used for social housing tenancies. Private landlords in England must use Form 4A — serving the old form will make your rent increase invalid.
- How much notice do I need to give to raise rent?
- You must give at least two months' notice. The effective date cannot fall earlier than 52 weeks after the last rent increase (or the start of the tenancy if rent has never been increased). Our date calculator handles both rules automatically.
- Can I raise rent in the first year of a tenancy?
- No. The effective date of a rent increase must be at least 52 weeks after the tenancy start date. This means you need to serve the notice at least 52 weeks minus 2 months after the tenancy began. Our calculator will tell you the earliest valid effective date.
- What happens if I serve the wrong form or wrong date?
- The notice is invalid and has no legal effect. You would need to serve a fresh notice with the correct form and recalculated dates, delaying your rent increase by at least two further months. Using Form 4A with correct dates avoids this entirely.
- Can my tenant challenge the rent increase?
- Yes. The tenant can apply to the First-tier Tribunal (Property Chamber) before the effective date. The Tribunal will determine the market rent, which could be higher, lower, or the same as the amount you proposed.
- Is this service prescribed?
- Form 4A states that the form can be completed and signed electronically. This service generates the prescribed form with your details filled in correctly. You are responsible for serving the notice on your tenant by a valid method.
