Form 4A Rent Increase Notice: Free Template and Generator for Landlords

Why Every Rent Increase Now Requires Form 4A

From 1 May 2026, Section 6 of the Renters' Rights Act 2025 made the Section 13 procedure the only lawful way to increase rent on a private assured periodic tenancy in England. Contractual rent review clauses, including CPI linked uplifts, fixed percentage increases, and stepped rent provisions, no longer have any legal effect. (Source: Renters' Rights Act 2025, section 6; Housing Act 1988, section 13(4A) as inserted.)

The prescribed form for this procedure is Form 4A. A letter, an email, or a landlord drafted document containing equivalent information does not satisfy the statutory requirement, even if every relevant detail is included. Only the official GOV.UK form is valid. (Source: GOV.UK, Assured tenancy forms for privately rented properties from 1 May 2026.)

If a landlord serves an invalid notice, the rent increase does not take effect. The tenant continues paying the existing rent, and the landlord must start the process again with a fresh Form 4A and a new two month notice period.

What Form 4A Asks For

Form 4A runs to nine pages, but the substantive information a landlord must provide fits into five sections. The fields that cause the most problems in practice are questions 4.4, 4.5, 4.6, and 4.7.

Questions 1 to 3 cover the property address, the landlord's name and address, and whether an agent is acting on the landlord's behalf. These are straightforward, but the names must match the tenancy agreement exactly. A discrepancy between the name on the notice and the name on the tenancy can give a tenant grounds to challenge the notice.

Question 4.4 asks for the date of the first rent increase after 11 February 2003. This date feeds into the 52/53 week calculation (see below). If the tenancy started after that date, this is the date of the first increase under the current tenancy. If there has never been an increase, the field is left blank.

Question 4.5 is the proposed new rent. This figure is the landlord's ceiling at the First-tier Tribunal. If the tenant challenges, the tribunal may confirm the proposed rent or reduce it. Under the amended rules, the tribunal cannot set a figure higher than the amount stated in the notice. (Source: Housing Act 1988, section 14(A1) as inserted by Renters' Rights Act 2025, section 7.)

Question 4.6 is the proposed start date for the new rent. This single date must satisfy three requirements simultaneously. Getting any one of them wrong makes the notice defective.

Question 4.7 asks the landlord to break down any service charges or charges included within the rent. If none are included, each line should show nil. Leaving the section blank entirely may create ambiguity.

The Three Timing Rules That Catch Landlords Out

The date in question 4.6 must satisfy all three of the following requirements, set out in section 13(2) of the Housing Act 1988 as amended.

Rule 1: Two months' notice. The notice must be served at least two calendar months before the new rent can start. For a monthly tenancy, this means a notice served on 1 July cannot propose a new rent start date earlier than 1 September. (Source: Housing Act 1988, section 13(3) as amended.)

Rule 2: The 52 week minimum. The first rent increase cannot take effect until at least 52 weeks after the tenancy began. Any subsequent increase must be at least 52 weeks after the previous increase took effect. (Source: Housing Act 1988, section 13(2)(b).)

Rule 3: The 53 week edge case. If the proposed start date for the new rent would fall more than six days before the anniversary of the date entered in question 4.4, the landlord must wait an additional week, making the minimum gap 53 weeks instead of 52. This prevents rent increase dates from drifting earlier each year, which matters most for weekly tenancies. (Source: Form 4A, Note A3; Regulatory Reform (Assured Periodic Tenancies) (Rent Increases) Order 2003.)

Rule 4: Alignment with the tenancy period. The new rent must start on the first day of a tenancy period. If rent is paid monthly from the 15th, the new rent must start on the 15th of a month. If rent is paid weekly from a Monday, the new rent must start on a Monday. (Source: Form 4A, Note A4.)

Calculating all of these by hand, especially across a portfolio of properties with different start dates and increase histories, is where mistakes are most commonly made.

Generate Your Form 4A in Minutes

LLCR's free Form 4A generator removes the guesswork. Enter your tenancy details, and the tool completes the official GOV.UK template with built-in date validation. It flags timing conflicts before they become invalid notices.

The tool is free, requires no account, and produces a PDF instantly. After downloading, the landlord prints the notice, signs it by hand, serves it on the tenant, and retains proof of service.

After You Serve: What to Keep and Why

A valid Form 4A is only useful if the landlord can prove it was served. Courts and tribunals expect evidence of service, and under the Renters' Rights Act, compliance records are scrutinised more closely during Section 8 possession proceedings.

Landlords are advised to keep a signed copy of the completed Form 4A, proof of service (a certificate of posting, tracked delivery receipt, or signed acknowledgement from the tenant), and a record of the date the notice was served and the method used.

These records matter well beyond the rent increase itself. If a landlord later needs to bring a possession claim on a rent arrears ground, the tribunal will check whether the current rent was validly increased. A gap in the paper trail can undermine an otherwise sound case.

One System for Notices, Certificates, and Deadlines

LLCR stores every Form 4A alongside your gas safety certificates, EICRs, deposit protection records, and tenancy documents. When a deadline approaches, you receive a reminder before it expires. If your compliance records are ever needed for a tribunal, a council inspection, or a possession claim, the Compliance Defence Pack pulls your evidence into a structured bundle at one click.
