Got a Section 21? You have 2 months before the move date — and your landlord may have a defective notice.

The 4 compliance gates that void a Section 21

A Form 6A is only valid if the landlord has cleared all four gates BEFORE serving it. Run through each one; if any answer is "no / never received", the notice is defective and you have a complete defence on Form N11R when the accelerated possession claim (N5B) lands.

Form 6A is the prescribed s.21 notice. If the form used is the wrong edition, has the wrong date, gives less than 2 months, or was served during the fixed term in breach of the tenancy agreement — those are additional defects on top of the four gates. Save your copy of the notice (front and back) and any email it arrived with.

The 31 July 2026 cliff — Section 21 is ending

The Renters' Rights Act 2025 ends the no-fault eviction regime. Phase 1 commenced 1 May 2026 under SI 2026/421 (Commencement No.2). Two dates matter:

• 30 April 2026, 4:30pm — last possible s.21 service. No landlord can serve a new Section 21 notice after that cutoff. If your notice is dated after 30 April 2026, it is not a valid s.21 at all — it may instead be a poorly drafted Section 8 ground notice, or simply void on its face.
• 31 July 2026 — the longstop. Any s.21 served on or before 30 April 2026 must have possession proceedings (Form N5B accelerated possession or Part 55 standard claim) issued at court by 31 July 2026. If the landlord misses that deadline, the s.21 route is permanently closed for that tenancy. The landlord then has to start over on a Section 8 ground — and most s.21 cases (no-fault, just wanting the property back) have no Section 8 ground available.

What this means in practice: if your s.21 was served in early 2026 and the landlord drags their feet on filing N5B at court, they may simply run out of time. The clock does not stop because they sent you a "final reminder" — only an actual court-issued claim freezes the deadline.

The post-1 May 2026 reality — Section 8 only

After 30 April 2026, the only route for a landlord to recover possession is Section 8 under the Housing Act 1988, Schedule 2. Section 8 requires the landlord to plead a specific named ground, prove it on evidence, and (for most grounds) attend a court hearing — there is no accelerated paper procedure equivalent to N5B. The most common grounds:

• Ground 8 — rent arrears. Mandatory ground if at least 2 months' rent is in arrears at the date of service AND at the date of the hearing. Paying down to under 2 months by the hearing defeats it. Universal Credit housing-element delays are an active defence theme.
• Grounds 10 & 11 — persistent arrears. Discretionary; court weighs hardship, the tenant's conduct, and whether arrears are likely to recur.
• Ground 14 — anti-social behaviour. Discretionary; landlord must produce evidence (witness statements, police reports, ASB warning letters). Vague complaints from neighbours rarely succeed.
• New 2025 grounds — sale and family occupation. The Renters' Rights Act 2025 introduces a sale ground and a family-occupation ground, both with notice periods of 4 months and a 12-month re-let ban afterwards. Misuse (relisting within 12 months) is a criminal offence and grounds for a Rent Repayment Order.

The shift to Section 8 means landlords lose the procedural advantage of accelerated paper-only possession. Hearings, oral evidence, and the court's discretion all come back. If your landlord serves a Section 8 notice after 1 May 2026, the analysis is different from the gates above — call Shelter on 0808 800 4444 the same day.

Your council's Homelessness Prevention Duty — apply NOW

The moment you receive a valid Section 21 notice, you are treated as threatened with homelessness under the Housing Act 1996 (as amended by the Homelessness Reduction Act 2017). That triggers concrete duties owed BY the council TO you:

• Section 184 — duty to inquire. Once you apply (in person, by phone, or online), the council must investigate your case and issue a written decision. Keep your s.21 notice and any tenancy documents to hand.
• Section 195 — Prevention Duty (56 days). If you are eligible and threatened with homelessness within 56 days, the council MUST take reasonable steps to help you keep your accommodation or secure alternative accommodation. They draw up a Personalised Housing Plan. This is owed regardless of priority need or local connection.
• Section 189A — Relief Duty. If you become actually homeless (e.g. bailiff date is set), the council owes a further 56-day Relief Duty to help you secure accommodation.
• Section 188 — interim accommodation. If you have priority need (dependent children, pregnancy, disability, DV) and may be homeless, the council must provide interim accommodation while it inquires.

Do not wait for the bailiffs. Apply for the Prevention Duty the same week you receive the s.21. Search "[your council name] homelessness application" on gov.uk for the right form and out-of-hours number. If the council tries to tell you to come back when you have a bailiff date — that is wrong; insist on a s.195 assessment in writing.

If your landlord serves a Section 21 in the UK:
1. Don't leave on the date in the notice — a notice is not a court order.
2. Check the 4 compliance gates: deposit protected in 30 days, gas safety cert before move-in, EPC served, How-to-Rent booklet served.
3. The deadline for landlord to issue court proceedings on ANY Section 21 is 31 July 2026. After that, Section 21 is dead — only Section 8 remains.
4. Apply to your council for the Homelessness Prevention Duty — they owe you 56 days under HRA 2017 s.195.
5. Call Shelter on 0808 800 4444 for free expert advice.

Even after the court grants the landlord a possession order, you do not have to leave until the bailiffs are appointed and serve a date. Anyone telling you otherwise — the landlord, an estate agent, a debt-collection firm — is wrong, and if they try to evict you any sooner that is a criminal offence under Protection from Eviction Act 1977 s.1.

Right now — what to do this week

1. Photograph the notice front and back, and the envelope / email it arrived in. Date-stamp the photo. Save it to cloud storage outside your home.
2. Check the four compliance gates above. Use the DPS / MyDeposits / TDS scheme lookup tools for the deposit. Use the public EPC register at gov.uk. Pull out the paperwork you got at the start of the tenancy.
3. Call Shelter on 0808 800 4444 the same day and describe the four gates over the phone. A Shelter adviser will tell you within minutes whether the notice is defective.
4. Apply to your council for the Prevention Duty under HRA 2017 s.195. In person if possible; in writing or by phone if not. Bring your s.21 notice.
5. Do NOT leave on the date in the notice. The notice is not a court order. The landlord still has to file N5B (accelerated) or a Part 55 standard possession claim, and you can file Form N11R as your defence.
6. Send a Defect Rebuttal Letter if any compliance gate fails. The Commoner Law Defect Rebuttal Letter (£7 / $9) walks through each gate with the right citations — Trecarrell, HA 2004 s.214, the 2015 Prescribed Requirements Regs.
7. If the landlord tries to evict without a court order — lock change, removing belongings, harassment, cutting utilities — call 999 (or 101 non-emergency). That is a criminal offence under PFEA 1977 s.1.

After you have called Shelter — the paid product

Shelter and Citizens Advice are always free and should always come first. Once you have a clear picture of which gate(s) the landlord missed, Commoner Law has a product tailored to this fight:

• UK Section 21 Defect Rebuttal Letter (£7 / $9) — formal letter to the landlord (and a parallel letter to their managing agent if applicable) setting out which compliance gate failed, citing the statute and case law, and demanding withdrawal of the notice within 14 days.
