Since 1 May 2026

Every rise needs Form 4A, and every Form 4A has three date rules.

Rent review clauses stopped working on 1 May 2026. Get one date wrong and that rise waits until you serve again: a whole rent period lost, at least, on every tenancy you got wrong.

Rule 1

Two months' notice

Every notice must reach the tenant at least two months before the new rent starts. A day short and that notice is no good.

Rule 2

52 weeks, sometimes 53

No rise within 52 weeks of the last one or of the tenancy starting, and 53 weeks once the dates have drifted. The form's question 4.4 exists for this.

Rule 3

The first day of a rent period

The new rent has to start on a rent day: the 20th for a tenancy that began on the 20th, a Monday for one that began on a Monday.

How it works

Every date, worked out

For each tenancy: the new rent, the earliest date it can lawfully start, and the last day you can serve the notice to keep that date.

Every notice, in one PDF

A schedule for the office, then each tenancy's completed Form 4A, ready to sign and serve. Hundreds of tenancies come out in minutes.

Straight answers

Is this the official Form 4A?
Every notice is Form 4A (05.26), the form prescribed for private landlords in England from 1 May 2026, laid out question by question with the government's wording unchanged and your figures filled in. The blank form is on GOV.UK if you want to compare.
How do you work out the earliest date the new rent can start?
The three rules in Note A of the form. The notice must be served at least two months before the new rent starts. No rise can start within 52 weeks of the tenancy starting or of the last rise, or 53 weeks where the form's Note A3 says so. And the new rent must start on the first day of a rent period. Rentdial takes the latest of those dates and moves it to the next rent day. We count the two months strictly (a notice served on 1 September supports 2 November, not 1 November), so every date we give you has a day to spare rather than a day too few.
What is the 53-week rule?
Because 52 weeks is a day or two short of a year, increase dates creep earlier. If the next 52-week date would fall more than six days before the anniversary of the tenancy's first increase after 11 February 2003, the landlord has to wait 53 weeks. That's why the form asks for that date (question 4.4), and why the tenancy list has a column for it.
Which tenancies does it cover?
Private-sector assured tenancies in England, including every tenancy that was an assured shorthold before 1 May 2026, with rent paid weekly, fortnightly, every four weeks or monthly. Not social housing (that's Form 4), agricultural occupancies (Form 5A), lodgers, or Rent Act regulated tenancies.
Can I still put the rent up using the rent review clause?
No. Since 1 May 2026 a rent increase only takes effect through a section 13 notice on Form 4A (or a tribunal decision), even when the tenant agrees to it. A rent review clause in the agreement no longer raises the rent.
What if a tenant challenges the increase?
The tenant can ask the First-tier Tribunal to set the market rent, as long as the application arrives before the new rent's start date. Until the tribunal decides they keep paying the current rent, and the tribunal can't make them pay more than you proposed. The tenant's route is explained on the notice itself and on GOV.UK.
How do I serve the notices?
Use a method your tenancy agreement allows. If it doesn't say, hand it to the tenant, leave it at their address, or send it by registered post, and keep proof. Enter the day each tenant will actually get the notice as the service date. If you post them, use the day they'll arrive.
Do you keep my tenants' details?
No. Your list is read in memory to work out the dates and draw the PDF, then it's gone. Nothing is saved, logged or used for anything else, and there's no account to set up.
What does the licence get me?
A code that takes the PREVIEW marks off. The same pack comes out clean, ready to sign and serve, for every rent review you do that year.
