Rent increase date calculator
Give the day the tenancy started, and the day of the last increase if there was one. The calculator gives the first day a new rent can start and the day the notice must be given by.
In short: In England a landlord can raise the rent once every twelve months, with a section 13 notice on Form 4A that gives at least two months of notice. The new rent must start on a rent day. A rent review clause in the agreement no longer counts.

Give the day the tenancy started to see the first day a new rent can begin.
The rule
- A rent increase needs a section 13 notice on the official form, Form 4A. A letter, a text or a clause in the agreement is not enough.
- The notice must give at least two months before the new rent starts.
- The rent can go up once in twelve months: not within twelve months of the start of the tenancy, and not within twelve months of the last increase.
- The new rent must start at the beginning of a rent period: a rent day.
- The law counts the twelve months as 52 weeks. This calculator uses twelve calendar months, which is never earlier than the law allows.
- There is no cap on the amount, but the tenant can ask the First-tier Tribunal, free, to decide the market rent. The tribunal can never set a rent higher than the landlord proposed.
- Allow extra days for the notice to arrive if it is posted.

Questions people ask
How often can a landlord increase the rent in England?
Once every twelve months, and only with a section 13 notice on Form 4A that gives at least two months of notice.
How much notice is needed for a rent increase?
At least two months, and the new rent must start on a rent day.
Can the rent go up in the first year of a tenancy?
A new rent cannot start within twelve months of the day the tenancy began. The notice can be given earlier, as long as the new rent starts after that.
Does a rent review clause in the agreement still work?
No. Since 1 May 2026 the only way to raise the rent of a private tenancy in England is the section 13 notice, or an agreement with the tenant after a tribunal decision.
Can a tenant challenge the new rent?
Yes. Before the new rent starts the tenant can apply, free, to the First-tier Tribunal, which decides the market rent. It can never set more than the landlord asked for.
