Form 4A (section 13 notice to increase rent)

Form 4A is the prescribed form for a landlord proposing a new rent on an assured tenancy in the private rented sector in England. GOV.UK's landlord guide says you complete Form 4A and give it to your tenant at least 2 months before the increase starts, and calls this the section 13 process. It says you can only increase the rent once a year and not in the first year of the tenancy. It also says to follow the section 13 process every time you increase the rent, even if the tenant has already agreed.

Form 4A names the tenants and the premises, so each tenancy has its own notice. If you have already completed one, you do not need to type the landlord and agent details again.

Upload the Form 4A you completed and the blank 05.26 form. RepeatForm copies the landlord and agent details across. Tenant, rent and dates can carry over too, but they belong to the old tenancy. Change each one.

RepeatForm lists every field it carried before you download. Check each one. Read Note A on the form for the dates. The signing date does not carry over, so you date and sign each notice yourself.

It does not fill your first one. You need a completed Form 4A to start from.

The sections below set out what GOV.UK says about notice, timing and a tenant's challenge. RepeatForm does not give legal advice.

GOV.UK's assured tenancy forms page lists Form 4A for landlords of privately rented property and Form 4 for social housing. The Form 4 itself says private landlords must not use it, apart from a narrow exception for some notices served before 1 May 2026. If a rent increase notice before that date used Form 4, GOV.UK says the notice period and rent in that form still apply. RepeatForm does not decide which form fits your tenancy. Read the GOV.UK guidance.

Form 4A is on GOV.UK's assured tenancy forms page, a 9-page PDF marked 05.26. RepeatForm does not supply the blank form. The link to GOV.UK is in the current edition section below.

1. The tenant(s) details. Names of each tenant (every tenant on a joint tenancy) and the address of the premises.

2. Details of the landlord. Name, contact address, phone and email. The form notes that phone and email are recommended but optional, and that giving an email address means the tenant and the tribunal may use it to serve documents on you.

3. Details of the agent, if you use one. Name, contact address, phone and email.

4. The rent. Current rent and how often it is paid; the date the tenancy started; the date of the most recent increase, if any; the date of the first increase after 11 February 2003, if any; the proposed new rent and its frequency; the date the new rent starts; and, for any charges included in the rent (council tax, water, fuel, communication services, fixed service charges), the existing and proposed amounts. The form's Note A sets out the dates the new rent can start on, and Note B covers the charges.

5. Signature. The landlord or the landlord's agent signs and dates it, and prints their name. For joint landlords, each signs in the additional signatures box, or they agree for one to sign for all.

Section 5 of the form, headed "What you (the tenant) should do next", is information for the tenant and is not filled in.

The form's Note A gives three requirements for the date in question 4.6: serve at least two months before the new rent starts; no first increase until 52 weeks after the tenancy began, and after that normally at least 52 weeks after the previous increase (53 weeks in some cases, as the note explains); and the new rent must start at the beginning of a tenancy period. Read Note A on the form itself, because RepeatForm does not work the dates out for you.

The form says you need to be able to evidence that you served the notice. If your written tenancy agreement sets agreed methods of service, use one of those. If it does not, the form says you can hand it to the tenant in person, leave it at the tenant's address or send it by registered post.

The tenant's part of the form says the new rent starts on the date in question 4.6 unless they agree a change in writing or refer the proposed rent to the tribunal before that date. This is the tenant's right under the form, not something you fill in.
