Section 21 Eviction Notice: Your Rights & How to Fight It

Updated 2026. England & Wales. Covers what makes a notice invalid, how to respond in writing, and what happens next.

Receiving a Section 21 notice (a "no-fault eviction") is stressful. But many Section 21 notices are invalid — and if yours is, the court will throw out the landlord's possession claim. You need to respond in writing.

First: check if your notice is valid

A Section 21 notice can be invalid if:

• Your deposit wasn't protected within 30 days of payment
• The landlord didn't serve the prescribed information about the scheme
• You weren't given a valid Energy Performance Certificate (EPC)
• You weren't given a Gas Safety Certificate
• You weren't given the government's How to Rent guide
• The eviction is retaliatory (you complained about repairs, got notice within 6 months — Deregulation Act 2015)
• The notice period is less than 2 months
• The landlord didn't make the required rent repayment plan (if advance rent was paid)

Responding in writing: why it matters

Even if the notice looks valid, you should respond. Your response:

• Puts the landlord on notice that you know your rights
• Creates evidence for the court if they proceed
• Can delay the court process if the notice is invalid
• Shows the court you're engaging (helps if you need more time)

What to do while the notice runs

1. Don't just leave — the landlord needs a court order to evict you
2. Gather evidence — deposit protection certificate, emails, photos of disrepair
3. Contact Shelter (0808 800 4444) or Citizens Advice
4. Apply for council housing/homelessness assistance if eviction looks likely
5. Attend any court hearing — your presence matters

If the landlord goes to court

Most Section 21 claims go through the accelerated possession procedure (paper-based, no hearing). If you've filed a defence (e.g. invalid notice), the judge will review it. If there's a dispute, a hearing will be listed. Attend it. Bring your evidence bundle.

Frequently asked questions

Can I ignore a Section 21 notice?

No. Even if the notice is invalid, don't ignore it. The notice may expire but the landlord can issue a new one. Respond in writing to put on record why it is invalid.

How long does a Section 21 eviction take?

Typically 4-8 months from notice to possession. The notice period is usually 2 months, then the landlord must get a court order. Bailiffs are the final stage.

What makes a Section 21 notice invalid?

Common reasons: deposit not protected in time, missing prescribed information, no EPC/gas cert/How to Rent guide, retaliatory eviction, or incorrect notice period.

Do I have to leave when the notice expires?

You don't have to leave voluntarily. The landlord must apply to the court for a possession order. If the notice is valid and the landlord follows the correct process, the court will usually grant it — but you can still attend the hearing and make representations.
