Section 13 rent increase calculator
Since 1 May 2026, rent for private tenancies can only go up once a year, using a Section 13 notice on Form 4A with at least two months' notice. Work out the first date a new rent can start.
The rules in short
- New rent may take effect no earlier than two months after service of the notice. RRA s.6(4)(a) replaced 'the minimum period' with 'two months' and s.6(5) omitted s.13(3) (old period-based minimum). Source
- If rent was previously increased by s.13 notice or s.14 determination, the next increase cannot take effect before 52 weeks after the last increase took effect (53 weeks in the s.13(3B) day-drift case). Source
- The new rent must take effect at the beginning of a new period of the tenancy specified in the notice. Source
- Tenant may apply to the tribunal under s.14(A3) to challenge a proposed new rent; the proposed rent takes effect as stated unless, before the new period begins, the tenant applies or the parties agree a lower rent (or no change). Source
- Tribunal determines open-market rent; the new rent is the open-market rent if lower than the proposed rent, otherwise the proposed rent (new s.14ZB(5)). Source
- New s.13(4A): rent for a period may not exceed the previous period's rent except via a s.13 notice (or agreement following one), a s.14 determination, or a written agreement for a lower rent after a determination. Any tenancy term providing for increases otherwise (rent review clauses, indexation, stepped rents) is of no effect. Source
- Written adverts/offers must state a specific rent; landlord/agent must not invite or encourage offers above the stated rent or accept such offers. 'To let' signs at the property are excluded. Penalty up to £7,000 (additional penalty for repeat within 5 years). Source
Questions
How often can I increase rent?
Once every 52 weeks, using a Section 13 notice. Rent review clauses in tenancy agreements no longer have any effect.
How much notice do I need to give?
At least 2 months, and the new rent must start at the beginning of a rent period.
Can the tenant challenge the increase?
Yes, at the First-tier Tribunal, before the new rent starts. The tribunal cannot set a rent higher than you proposed.
