Section 13 notice deadlines: your timeline from notice to decision
Every Section 13 challenge has a clock attached. Here is exactly how long you have at each step — from the day a notice drops through your door to the day the tribunal decides.
Every rent increase comes with a ticking clock. Miss the wrong deadline and the increase becomes binding even if your landlord's notice had errors. Understanding the timeline is the single most important thing a tenant can do in the first week after receiving a notice.
This guide walks through each deadline in order — from the day the notice arrives to the day the tribunal posts its decision.
Day 0: the notice arrives
A landlord increasing rent on a periodic assured shorthold tenancy in England must serve a Section 13 notice using the prescribed form (Form 4 under current law, Form 4A from 1 May 2026).
Check three things the moment it arrives.
- The prescribed form. Is it the correct Form 4 or 4A with all sections completed?
- Your details. Is your name and address correct?
- The date served. When did you actually receive it? That starts the clock.
If any of those are wrong, the notice may be invalid. An invalid notice cannot be "fixed" — the landlord has to start again with a new one.
For almost all tenants, the first week is the most important. Use it to check the notice carefully, gather evidence and decide whether to challenge. The deadlines later in the process are long — the actions you take in week one set everything up.
The minimum notice period
The landlord must give you a minimum notice period before the new rent can take effect. The rules depend on when the notice is served.
Before 1 May 2026
- Monthly or weekly rent: at least 1 month
- Quarterly rent: at least 3 months
- Yearly rent: at least 6 months
From 1 May 2026 onwards
Under the Renters' Rights Act 2025, the minimum notice period becomes 2 months for all rent frequencies. This is a significant protection for weekly and monthly renters.
How the notice period is calculated
It runs from the date served (or the date the notice is deemed served, usually a few working days after posting). The new rent can take effect no earlier than the first day of a rent period that starts after the minimum notice has expired.
Practical example: if you pay monthly on the 1st, and the notice is served on 10 April for a minimum one-month period, the new rent cannot take effect before 1 June — because the first rent period starting after the minimum notice expires begins on that date.
Week 1: check validity and build a case
In the first week after a notice arrives, do three things.
- Check for procedural errors. Wrong form, incorrect dates, wrong rent frequency, or a notice period that is too short all make the notice invalid.
- Gather market evidence. Screenshot three to four similar properties listed in the last 60 days on Rightmove or Zoopla. The market rent is your strongest argument at tribunal.
- Draft a counter-offer. Most rent disputes resolve informally. A calm, evidenced letter to the landlord is often enough.
Our free rent increase checker will review your notice in about two minutes and flag procedural issues. If there are grounds to challenge, you receive a pack including a counter-offer letter template.
Week 2 to 4: negotiate
The negotiation window is roughly the time between sending your counter-offer and the date the new rent is due to start. Use it fully.
If the landlord responds:
- Write every conversation down in an email summary
- Do not agree verbally — wait for written confirmation
- Keep every reply
If the landlord does not respond within 14 days, move to the formal challenge. Waiting is not a neutral choice — your formal deadline is approaching.
The critical deadline: the day the new rent starts
This is the most important date in the entire timeline. It is printed on your Section 13 notice.
You must apply to the First-tier Tribunal before the new rent takes effect. Once that date passes without an application, the increase becomes binding — even if the notice had errors.
Apply at least 7 to 10 days before to give yourself a buffer. HMCTS uses Royal Mail and online submission, and occasional admin delays do happen. The tribunal cannot accept a late application on sympathy grounds.
To apply, you use Form 6 (Application for Rent Determination) which is available free on GOV.UK. There is no application fee.
Week 1 to 2 after application: tribunal confirmation
You will receive an acknowledgement from the tribunal within 1 to 2 weeks. This confirms:
- Your case reference number
- Whether the case will have an oral hearing or be decided on paper
- The earliest likely hearing date
The original rent continues while your case is pending — you do not pay the increased rent until the tribunal has decided.
Week 4 to 8: directions and evidence bundle
The tribunal will issue written directions setting deadlines for:
- Evidence bundles from both sides (usually 14 days before the hearing)
- Any property inspection dates
- Any disclosure requirements
These are firm deadlines. Missing a direction can result in evidence being excluded.
Week 10 to 14: the hearing
Most hearings happen 10 to 14 weeks after the application. They are usually:
- By video (CVP) — 30 to 90 minutes
- In person — rarer but does occur at regional tribunals
- On paper — only if both parties agree
See [[how-to-prepare-for-rent-tribunal-hearing|how to prepare for a rent tribunal hearing]] for what to expect on the day.
Week 12 to 18: the decision
The tribunal writes its decision and sends it to both parties by post and email. This is usually 2 to 6 weeks after the hearing.
The decision will set out:
- The rent the tribunal has determined
- The date the new rent takes effect
- A short explanation of the reasoning
Pre-1 May 2026: decisions can be backdated
Under current rules, the tribunal can backdate a decision to the original effective date on the notice. This means a decision can create either an arrears or a rebate depending on which way it went.
From 1 May 2026: no backdating
From the Renters' Rights Act coming into effect, tribunal decisions on rent apply only from the decision date forwards. There is no backdating. This is a meaningful protection for tenants who succeed.
What happens if you miss the deadline?
If the new rent date passes without your tribunal application, you lose the right to a formal challenge for that notice.
You still have options:
- Negotiate informally (no formal status, but landlords sometimes agree)
- Wait for the next notice cycle (landlords can only raise rent once every 52 weeks)
- Look for procedural errors in the next notice
None of these are as strong as a timely tribunal challenge. Treat the deadline seriously.

Frequently Asked Questions
+How long do I have to challenge a Section 13 notice?
You must apply to the First-tier Tribunal before the date the new rent is due to take effect. Once that date passes without an application, the increase becomes binding by default.
+Is the notice period calendar days or working days?
Calendar days. The minimum notice period runs in full months or weeks depending on your rent payment frequency, and weekends and bank holidays count.
+Can my landlord shorten the notice period?
No. If the notice is less than the legal minimum for your rent frequency, it is invalid and you can ignore the increase. Most procedural failures are honest mistakes, not tactics.
+What happens if I apply on the last day before the new rent starts?
Your application is valid as long as it is received by the tribunal before the effective date. It is still better to apply 7 to 10 days before to give yourself buffer against admin delays.
+How long does the whole tribunal process take?
From application to written decision is typically 8 to 16 weeks. You will usually have a hearing within 10 to 12 weeks, and the decision arrives 2 to 6 weeks after that.

Is my landlord raising the rent just to force me out? What the law actually allows
A large rent increase can feel like a quiet eviction, especially now that no-fault eviction is gone. But a Section 13 must reflect genuine market rent, not what would make you leave. Here is where you stand.
I already started paying the higher rent: can I still challenge it or get it back?
Paying the new rent for a few months does not automatically lock you into it. Whether you can still challenge or reclaim depends on two separate questions, and this walkthrough explains both.
The tribunal set my rent between what I pay now and what my landlord asked: did I still win?
Winning a rent challenge rarely means the rent stays frozen. It usually means the tribunal sets a fair figure below what your landlord asked. Here is how to work out what you actually saved.
Your landlord did up the flat and now wants a big rent rise: can you still challenge it?
A new kitchen or bathroom lets a landlord ask for more, but not for any figure they like. Here is how to tell a fair improved-market rent from an overreach, and when you can still challenge.
