Section 13 Notice (Form 4) Check
Validating Your Rent Increase Notice
Did you get a Form 4? Check if the increase is legal.
A rent rise notice can look official and still be unenforceable if the dates, the tenancy period, or the form requirements are wrong. This page helps you do a fast legality check on a Section 13 rent increase notice in England, and shows what to do next if something does not line up.
Know where you stand before you reply, and avoid accidentally accepting a higher rent by paying it without meaning to.
Built around GOV.UK Form 4 requirements and GOV.UK tribunal guidance on market rent determinations.
- Covers the 52 week rule, correct start date, and notice length. These are the three mistakes that most often sink a notice.
- Includes a tenant action plan: accept, negotiate, or challenge, plus the deadline that matters.

Check form type, notice length, tenancy period start date, 52 week limits, first year restrictions, and completion errors. Then decide whether to accept, negotiate, or apply to tribunal.
Deadline that matters
If you want tribunal review of the rent, you usually need to apply before the new rent start date written on the notice.
Keep proof
Write down when you received the notice and keep the envelope if it was posted.

Validity check
A Section 13 increase is only enforceable when the landlord uses the statutory route correctly. Start here.
Section 1
The 60 second tenant checklist
Is it the right document for England (Form 4)?
For assured or assured shorthold periodic tenancies in England, the standard Section 13 notice is the government Form 4. Compare what you received against the official Form 4. Look for Form 4 wording, premises in England, and tenant guidance notes about the tribunal option. Red flag: a text, email, or informal letter does not automatically change rent unless you agreed, and paying more can look like acceptance.
Does it give enough time before the new rent starts?
The minimum notice depends on your tenancy period. Monthly or weekly tenancies usually need at least one month. Quarterly tenancies usually need three months. Yearly tenancies usually need six months. See the notice table on Citizens Advice.
Is the proposed start date the correct day for your tenancy period?
The start date must be after the minimum notice has run, and it should be the first day of a tenancy period, not just any calendar day. Example: if your tenancy runs from the 5th to the 4th, the new rent should start on the 5th, even if you pay on the 1st. Shelter explains this clearly for Section 13 notices here.
Has your landlord used Section 13 too recently?
Under the statutory process, landlords generally cannot use it more than once in a 52 week window. If you already had a Section 13 increase within the last year, a new one may be premature. See the statutory timing rules in Shelter legal guidance.
Are you still within the first year protection?
Shelter notes that rent cannot go up by Section 13 in the first year of your tenancy. If you had a fixed term and then rolled into periodic, the timing can still be measured from the start of the tenancy relationship. See the tenant guide on Section 13 notices.
Is it properly completed (names, address, rent, signature, date)?
Even with the right form, it should be completed sensibly. Check names, property address, current rent and proposed rent, and that it is signed and dated. Obvious errors can signal the notice may not be valid.
Is there a rent review clause that changes the rules?
If your contractual periodic tenancy has a binding rent review clause, a Section 13 notice is not always the correct tool. Shelter explains that Section 13 is for periodic tenancies where there is no rent review clause here. But once a fixed term ends and a statutory periodic tenancy arises, Section 13 may be the right route instead.
If any check fails, what should you do?
Do not panic, but do not ignore it.
- Keep paying your current rent until you have confirmed enforceability (and get advice if needed).
- Ask the landlord or agent to re issue a compliant notice.
- If the figure looks above market, consider negotiation or tribunal routes.

If you later apply to tribunal, GOV.UK guidance says you should also send a copy to your landlord or representative.
Important update: rules change from 1 May 2026
This page is written for the process that applies before 1 May 2026. GOV.UK guidance for landlords says that from 1 May 2026 rent increases will be standardised through the Section 13 process, with at least two months notice and a new form (Form 4A). It also says rent review clauses that automatically raise the rent will no longer apply.
The GOV.UK guide to the Renters Rights Act also says disputed increases will not be backdated and tenants should not end up paying more than the landlord asked for when they challenge a rent increase.

| Frequency | Generally limited to once every 52 weeks under the statutory Section 13 process. | Shelter legal guidance |
| Form type | For assured periodic tenancies in England, the prescribed notice is Form 4 before 1 May 2026. | GOV.UK assured tenancy forms |
| Notice period | Depends on the tenancy period. Often one month, longer for quarterly and yearly tenancies. | Citizens Advice |

| 2026 changeover | From 1 May 2026, GOV.UK guidance says the notice period becomes at least two months and the form changes to Form 4A. | GOV.UK rent increase guidance |
If the rent feels too high (even if the notice is valid)
A compliant notice can still propose a rent that is above local market level. You have three practical paths.
Accept
If you accept, pay the new rent from the date on the notice. Update standing orders, and notify benefits teams if relevant. Keep a screenshot or letter confirming you accepted so you avoid later confusion.
Negotiate
Tribunal is not your only option. You can propose a different figure, ask for a phased increase, or trade certainty for a longer agreement. Keep everything in writing.
Ask a tribunal to determine market rent
You can apply to the First tier Tribunal (Property Chamber) to decide the open market rent. Before 1 May 2026, GOV.UK guidance says the market rent can be lower, the same, or higher than what the landlord proposed, so understand the risk before you apply.
Tribunal deadline that catches people out
Your application must be submitted before the proposed start date on the notice. GOV.UK is direct about applying before that start date, even if you are still collecting evidence. See apply for a market rent determination.
What form do tenants use right now?
GOV.UK provides the Rents 1 form and explains how to submit it, including sending a copy to the landlord or representative. Shelter legal guidance also notes that Form 6 is the prescribed form, and Rents 1 is available as an alternative.GOV.UK guidance | Rents 1 PDF | Shelter legal notes
What evidence tends to matter most
Photos, room sizes and condition, amenities, repair issues, and comparable rents. GOV.UK lists evidence types and says actual agreed lettings are usually stronger than adverts.
Crucial nuance: the tribunal does not validate your notice
GOV.UK guidance says the tribunal decides market rent and cannot decide on the legal validity of the landlord notice of increase. If you think the notice is invalid, you can still explain that in your application.

Frequently asked questions
Short answers for quick checks and voice search.
Can my landlord raise rent with a message or email?+
A landlord can ask, but your rent does not automatically change unless you agree or a correct statutory process is used. Paying a higher rent can look like acceptance, so get clarity in writing first.
Can Section 13 be used during my fixed term?+
A landlord can serve a Section 13 notice during a fixed term, but the increase should only take effect after the tenancy becomes statutory periodic and after the required notice period. Always double check the proposed start date.
What if the start date on the notice does not match my tenancy period?+
That is a common compliance issue. The proposed new rent date needs to be the first day of a tenancy period, not just any calendar day.
How often can Section 13 notices be used?+
Under the statutory route, rent increases are generally limited to once every 52 weeks.
If I apply to tribunal, can the rent go higher?+
Before 1 May 2026, GOV.UK guidance says the tribunal can set a market rent that is lower, the same, or higher than the landlord proposed. From 1 May 2026, the Renters Rights Act guide says tenants should not pay more than the landlord asked for when challenging a rent increase.
Does applying to tribunal stop eviction action?+
A rent increase dispute does not automatically stop a landlord using other legal routes. If you are facing eviction risk or urgent deadlines, get advice early and keep copies of all paperwork.
What if I cannot afford the increase at all?+
You can try negotiation first. If you apply to the tribunal, GOV.UK guidance explains you can ask it to consider financial hardship when deciding the payment timing.
I am not in England. Does Form 4 still apply?+
Form 4 is for premises in England. Scotland, Wales, and Northern Ireland use different rent increase systems, so do not rely on an England form outside England.
