Is your rent increase notice actually valid?
Enter the details from your landlord's section 13 notice. In two minutes you'll know whether it meets the rules in England, and the date you must act by.
Five rules a section 13 notice has to meet
If a notice gets any of these wrong, it is not valid and your rent cannot go up on the strength of it. The landlord would have to start again with a new notice.
Form 4A
From 1 May 2026 the increase must be proposed on the prescribed section 13 form, not a letter or email.
Two months' notice
At least two months between you receiving the notice and the new rent starting.
Once a year
No increase within 52 weeks of the last one, or of the tenancy starting.
Right start date
The new rent has to begin on the first day of a rental period.
Signed and correct
Signed by the landlord or agent, with your correct name and address.

Questions tenants ask
What does Section13Check do?
You enter the details from your landlord's rent increase notice. We check it against the section 13 rules that apply in England, show you whether it looks valid and your key deadline, and can then prepare a personalised pack: a letter to your landlord, tribunal guidance with your answers filled in, and a deadline checklist.
What changed on 1 May 2026?
The Renters' Rights Act changed how private rents can go up in England. Landlords must now use a section 13 notice on Form 4A and give at least two months' notice. Rent can only go up once a year, rent review clauses in tenancy agreements no longer work, and you cannot be evicted for challenging an increase. If you challenge a notice given on or after 1 May 2026, the tribunal cannot set a rent higher than the landlord asked for.
Who is it for?
Private tenants in England with an assured or assured shorthold tenancy who have received a rent increase notice. It is not designed for social housing tenants, regulated (fair rent) tenancies, lodgers, or tenants in Wales, Scotland or Northern Ireland, where different rules apply.
What happens if my notice is not valid?
If the notice is not valid, your rent does not go up because of it. Your landlord would need to serve a new, correct notice. The pack includes a letter explaining the problem to your landlord, and you can ask the First-tier Tribunal to decide whether the notice is valid.
What is the deadline to challenge?
You must apply to the First-tier Tribunal (Property Chamber) before the date the new rent is due to start, as stated in the notice. We show this date as soon as you complete the check.
How much does the tribunal cost?
The tribunal application fee is £47 for notices dated on or after 1 May 2026. You may get help with the fee if you have little or no savings and receive certain benefits or are on a low income. This fee is paid to the tribunal and is separate from the price of the pack.
Is this legal advice?
No. Section13Check is a document helper, not legal advice. We explain the published rules and prepare documents from your answers. For advice about your situation, contact Shelter, Citizens Advice or a local law centre.
What do I get in the pack, and how?
A PDF with your letter to the landlord (an invalid-notice letter or a negotiation letter), step-by-step tribunal guidance with pre-filled answers, an evidence list and a dated checklist. You can open it straight after payment and we email you a copy.
How much does the pack cost?
The pack costs £5.00 (GBP), charged once via PayPal. Payment is handled by PayPal; we never see your card details.
