Form 4A Section 13 Rent Increase Notice (post-RRA 2026)
From 1 May 2026 in England, the only valid way to increase rent on an Assured Periodic Tenancy is to serve a Form 4A notice under section 13 of the Housing Act 1988. The old Form 4 is no longer valid. Our UK template tracks the prescribed structure, preserves the operative First-tier Tribunal challenge wording verbatim, and includes a compliance audit, comparable rent evidence schedule and joint-landlord handling.

WHAT TO DO IF YOU DO NOT AGREE WITH THE PROPOSED NEW RENT
You have the right to challenge the proposed new rent.
If you do not agree with the proposed new rent, you can apply to the First-tier Tribunal (Property Chamber — Residential Property) to decide what a reasonable rent for the property would be in the open market. You must apply before the date on which the new rent is proposed to take effect (the date in paragraph 3.3 above).
You must use Form RR1 to make the application. The form is available from the Tribunal's website at www.gov.uk/housing-tribunals/challenging-rent-increase. There is no fee to apply.
If you apply to the Tribunal, the Tribunal will decide what the open-market rent for your property would be. If the Tribunal decides on a lower figure, that figure will be the rent payable from the date this notice proposed the new rent would take effect (or any later date the Tribunal directs). The Tribunal cannot decide on a figure higher than the new rent proposed in this notice.
If you do not apply to the Tribunal by that date, the proposed new rent in paragraph 3.2 above will be payable from the date in paragraph 3.3.
You may wish to take independent advice (for example, from Citizens Advice, Shelter, your local Council's tenancy relations officer, or a solicitor) before deciding whether to apply to the Tribunal.

COMPLIANCE AUDIT — STATUTORY CONDITIONS
The Landlord confirms the following compliance checks (any "No" finding invalidates the notice and the Landlord should re-serve once the condition is satisfied):
1. 52-week tenancy duration check (Renters' Rights Act 2024 condition): CONFIRMED — the tenancy began at least 52 weeks before the proposed effective date.
2. 12-month gap check: NOT APPLICABLE — this is the first rent increase under this tenancy.
3. First-day-of-rent-period check: CONFIRMED — the effective date falls on the first day of a rent period.
1. 52-week tenancy duration check (Renters' Rights Act 2024 condition): CONFIRMED — the tenancy began at least 52 weeks before the proposed effective date.
2. 12-month gap check: NOT APPLICABLE — this is the first rent increase under this tenancy.
3. First-day-of-rent-period check: CONFIRMED — the effective date falls on the first day of a rent period.
6.
RENT INCREASE HISTORY
The chronology of past rent increases under this tenancy is set out below (provided to evidence compliance with the 12-month gap rule):
No previous rent increase. Tenancy commenced 1 September 2024 at £1,850.00 per calendar month.
No previous rent increase. Tenancy commenced 1 September 2024 at £1,850.00 per calendar month.
7.
REASON AND MARKET EVIDENCE
Reason for the proposed increase: Open-market rent for two-bedroom flats in Battersea has increased materially since September 2024. The proposed increase to £1,950 represents a 5.4% uplift, broadly below local market growth (Rightmove data 2026 — Battersea SW11 average two-bed rent £2,070).
Comparable open-market rent evidence (for the Landlord's records and any First-tier Tribunal proceedings — three comparable properties is the usual minimum):
1. Flat 12, 34 Acacia Gardens, Battersea SW11 6FT — two bedrooms, similar size and finish, currently let at £1,975 per calendar month (Foxtons listing ref FX2026-4421, June 2026).
2. Apartment 6, 18 Wisteria Court, Battersea SW11 7BH — two bedrooms, balcony, let April 2026 at £2,020 per calendar month (Hamptons letting record).
3. Flat 8, 41 Acacia Gardens, Battersea SW11 6FT — two bedrooms, identical layout, let March 2026 at £1,975 per calendar month (Knight Frank letting record).
This evidence may be relied on if the tenant applies to the Tribunal under Form RR1. The Tribunal applies an open-market test (s.14 HA 1988): what the property might reasonably be expected to be let for on the open market by a willing landlord, taking into account improvements made by the tenant other than under any obligation.

SERVICE OF NOTICE
This notice was sent by first-class post on 2026-06-15. Where service is by first-class post or by being left at the property, the notice is deemed served the working day after posting or leaving (see s.196 Law of Property Act 1925 / Tenancy Agreement service clause). Where service is by recorded delivery, service is effective on the day of signed receipt. The address for service of any reply or Tribunal correspondence on the Landlord is: 8 Beaumont Avenue, Richmond TW10 6LB.
9.
FIRST-TIER TRIBUNAL CHALLENGE PROCESS — FURTHER DETAIL
Should the tenant apply to the First-tier Tribunal (Property Chamber — Residential Property) under Form RR1, the procedure is as follows: (a) the application must be received before the effective date in paragraph 3.3 above; (b) the Tribunal will give directions, typically requiring an exchange of comparable market evidence (the Landlord should rely on the schedule in this notice and any further evidence); (c) the Tribunal will determine an open-market rent under s.14 Housing Act 1988, disregarding any improvements made by the tenant other than under an obligation in the tenancy agreement; (d) the determined rent cannot exceed the rent proposed in paragraph 3.2 above (the Tribunal cannot raise it higher); (e) the determined rent takes effect on the date proposed in paragraph 3.3 unless the Tribunal directs otherwise; (f) either party may apply for permission to appeal the decision (on a point of law) within 28 days. Both the Landlord and the tenant should approach the Tribunal as a quasi-judicial process and may benefit from professional advice.
10.
TENANT PET RIGHT — CONTEXT NOTE
Note for context: under the Renters' Rights Act 2024 (in force 1 May 2026), the tenant has a statutory right to keep a pet at the property subject to the Landlord's reasonable consent. The Landlord must not unreasonably refuse consent and any refusal must be in writing with reasons. This notice does not affect that right. Any pet damage that the tenant does not rectify or compensate may give rise to a separate s.8 ground for possession (Ground 8A — discretionary).
11.
PAYMENT DETAILS FROM THE EFFECTIVE DATE
From the effective date in paragraph 3.3, the new rent should be paid as follows:
From 1 September 2026, please pay £1,950.00 by standing order on the 1st of each month to: account name "Whitmore Property Letting", sort code 20-92-46, account number 81234572. Standing-order reference: ACACIA-4.

What Is a Form 4A Section 13 Rent Increase Notice?
Form 4A is the prescribed UK notice that a landlord must use to propose a new rent for an Assured Periodic Tenancy under section 13(2) of the Housing Act 1988. It replaced the old Form 4 under the Renters' Rights Act 2024 commencement regulations and is the only valid method for landlords in England to increase rent under a statutory periodic assured tenancy from 1 May 2026 onwards.
Form 4A is a strictly prescribed form. Its core content — including the operative wording informing the tenant of their right to challenge the proposed rent at the First-tier Tribunal (Property Chamber) — cannot be altered, abbreviated or substituted with a letter or email. A rent increase notice that is not on the prescribed Form 4A is likely to be invalid under English housing law, and the proposed new rent will not become payable.
The Form 4A regime applies to standard Assured Periodic Tenancies across England. It does not apply to four categories: high-rent tenancies (annual rent above £100,000); lodger / Rent a Room arrangements; lettings to companies; or Rent Act 1977 regulated tenancies. For these, alternative rent-review mechanisms (contractual or statutory) apply outside the post-RRA 2026 framework.

How to Create a Form 4A Section 13 Rent Increase Notice
Follow these steps to serve a valid UK Form 4A notice.
- 1
Verify Eligibility
Confirm the tenancy is a standard Assured Periodic Tenancy in England (not lodger, company, Rent Act 1977 regulated, or high-rent above £100,000/year). Confirm the tenancy began at least 52 weeks before the proposed effective date and that any previous rent increase took effect at least 12 months ago.
- 2
Enter the Landlord and Tenant Details
Provide the landlord name (matching the tenancy agreement exactly), s.48 address for service, and (if applicable) joint landlord names. Enter the tenant name(s) exactly as on the tenancy agreement — joint tenants must all be named. Where a letting agent serves the notice, record the agent's details.
- 3
Calculate the Effective Date
The proposed effective date must (a) be at least 2 months after the date of service; (b) fall on the first day of a rent period (counting from the original tenancy start); (c) be at least 12 months after any previous rent increase effective date; and (d) leave the tenancy at least 52 weeks old. Any failure invalidates the notice in English law.
- 4
Enter Rent Details
Provide the current rent (per the rent period — weekly/monthly/quarterly/yearly), the proposed new rent, and the rent period. The template auto-formats the amounts in pounds sterling and confirms the period explanation in the body.
- 5
Add Expert Compliance + Evidence (recommended)
In Expert mode, complete the compliance audit (52-week, 12-month, first-day-of-period), past increase chronology, reasons for the proposed increase, and three comparable rents from local market evidence. Specify service method, joint-landlord signature basis, and include the FTT challenge process explainer. Download as PDF and serve on the tenant by your chosen method.

Reviewed for English law
Prescribed Form — Mountain v Hastings Strict Compliance
In Mountain v Hastings [1993] 25 HLR 427, the Court of Appeal confirmed that statutory housing notices in England must follow the prescribed words of the schedule. A notice that omits or alters the prescribed Tribunal challenge statement is unlikely to be valid. The Renters' Rights Act 2024 commencement regulations introduced Form 4A as the new prescribed form from 1 May 2026, replacing the former Form 4. The 2020 Court of Appeal decision in Pease v Carter [2020] EWCA Civ 175 provides a limited "saving" construction for minor errors where the tenant has not been misled, but landlords should not rely on it as a workaround.
Section 13 Conditions — All Four Must Be Met
Under section 13 Housing Act 1988 as amended by the Renters' Rights Act 2024, a Form 4A notice must satisfy four cumulative conditions: (1) at least 2 months' notice from service to effective date; (2) the effective date falls on the first day of a rent period; (3) rent must not have been increased in the previous 12 months; and (4) the tenancy must have begun at least 52 weeks before the proposed effective date. Any failure invalidates the notice. The template includes a self-audit clause for each of these conditions in Expert mode.
Tenant Challenge at the First-tier Tribunal
A tenant in England who disagrees with the proposed rent has the right to apply to the First-tier Tribunal (Property Chamber — Residential Property) using Form RR1 before the effective date. The Tribunal applies the section 14 Housing Act 1988 open-market test: what the property might reasonably be expected to be let for on the open market by a willing landlord, disregarding any improvements made by the tenant other than under an obligation. The Tribunal cannot decide on a figure higher than the rent proposed in the notice, but can lower it. Comparable open-market rent evidence (typically three comparable properties) is the standard form of Tribunal defence.
Service and Tenant Fees Act 2019
Service of the notice must use a permitted method. Section 196 of the Law of Property Act 1925 (or the service clause in the tenancy agreement) sets the deemed-service rules — first-class post and "left at the property" are deemed received the working day after; recorded delivery is effective on signed receipt; email is valid only where the tenancy agreement permits. The Tenant Fees Act 2019 prohibits any fee or surcharge in connection with the rent increase. The landlord must also have complied with deposit protection rules and have an EPC, gas safety certificate and electrical safety report in force where required — the FTT may consider any breach if challenged.
