Check the dates on a Form 4A rent increase before you serve it, and write the cover note to your tenant

The problem

Since 1 May 2026 a rent increase for an assured periodic tenancy in England must go on Form 4A, at least two months before the new rent starts, once a year at most, with the date falling at the start of a tenancy period and at least 52 weeks after the last increase (or 53 in some cases). A wrong date is easy to make, and the tenant can ask the First-tier Tribunal to decide the open-market rent. AI can lay out a date worksheet with blanks and draft a short, friendly cover note. It does not work out your dates or say your notice is valid: you count them on a calendar against the form's own notes.

What AI does

AI lays out a worksheet for the dates on a rent increase notice, with blanks for you to fill in, and drafts a short, friendly cover note for your tenant. It does not work out your dates or say the notice is valid; you check them against the official form's notes (England).

Time

The steps, in short

1. Gather the relevant tenancy dates from your own records.
2. Read the official form's notes and count the dates yourself.
3. Have AI lay out the worksheet and draft the cover note.
4. Complete the official form yourself, and get advice from a solicitor or landlord body before serving it if unsure.

A short sample prompt

I'm a landlord in England preparing a rent increase notice. Lay out a worksheet with blanks for the dates I will fill in myself: [the dates you need]. Then draft a short, friendly cover note for my tenant. Do not calculate dates or comment on validity.
