Section 21 Notice Guide (2026)

What Form 6A is

Form 6A is the statutory (“prescribed”) form a landlord in England had to use to give a tenant notice under section 21 of the Housing Act 1988. Section 21 allowed a landlord to recover possession of a property let on an assured shorthold tenancy (AST) without giving any reason — hence the label “no-fault eviction”. This contrasts with section 8, which requires the landlord to rely on specific grounds, such as rent arrears or breach of the tenancy. Because no reason was needed, Parliament balanced section 21 with a demanding set of preconditions. A landlord who got any one of them wrong served an invalid notice — and an invalid Form 6A cannot found a possession order. This is, by a wide margin, the most common reason section 21 claims have failed in the county court. Note the geography. This guide covers England. Wales operates a separate regime under the Renting Homes (Wales) Act 2016, with its own notices and rules — Form 6A does not apply there. And note the sector. Since 1 May 2026 the abolition applies to the private rented sector. GOV.UK now lists Form 6A among the “forms for social housing assured tenancies”: a private registered provider of social housing letting on an assured shorthold tenancy can still serve a section 21 notice on Form 6A, because the Renters’ Rights Act changes will not apply to those tenancies until 2027 at the earliest.

When Form 6A was used (and when it could not be)

Form 6A was used to bring an assured shorthold tenancy to an end on a no-fault basis once the landlord wished to recover the property. But there were firm timing limits on when it could be served and when proceedings could begin:

• Not in the first months of the tenancy. A section 21 notice could not be served within the first four months of the day the tenancy began — confirm this bar still applies to your facts.
• Not while certain enforcement notices were live. If the local authority had served a relevant improvement notice or emergency remedial works notice on the property, a section 21 notice served within the prescribed period afterwards was invalid (part of the “retaliatory eviction” protections).
• A “use it or lose it” shelf life — now a hard long-stop. Once served, a section 21 notice could only support proceedings for a limited time. For pre-1 May 2026 private-sector notices, that window has now closed: the claim had to be issued by the earlier of the notice’s expiry and 31 July 2026.
• Minimum notice period. The tenant had to be given at least the statutory minimum notice — generally two months — running from when the notice was given. Check the current figure before relying on any date.

The strict validity conditions

For a Form 6A to be valid, the landlord generally had to satisfy all of the following. A single failure is usually fatal to the claim.

Condition	What it required	Why notices failed
Tenancy deposit protected	Any deposit taken must have been protected in an authorised scheme within the required time.	Late or no protection — a leading cause of invalid notices.
Prescribed information given	The deposit “prescribed information” must have been served on the tenant.	Information not given, or given late or incompletely.
Energy Performance Certificate (EPC)	A valid EPC must have been provided to the tenant.	EPC never supplied to the tenant.
Gas safety certificate	The current gas safety record must have been provided.	Certificate missing, expired, or supplied late.
How to Rent guide	The government’s “How to Rent” checklist must have been given (the correct, current version).	Not given, or an out-of-date version used.
Timing rules	Not served in the first four months; not during a protected improvement-notice period.	Served too early or as a retaliatory response.
Correct prescribed form	The valid version of Form 6A in force at the date of service.	An outdated form used after a revision.
Notice period	At least the statutory minimum notice, expiring on the correct date.	Period miscalculated or expiry date wrong.

If you are the tenant, each row above is a potential line of defence. If you are the landlord relying on a pre-commencement notice, each row is a box that must already have been ticked when the notice was served — you cannot fix a defect retrospectively by re-serving now that section 21 has gone.

What replaced section 21: the section 8 route

With section 21 abolished, possession in England is now sought through section 8 of the Housing Act 1988, which requires the landlord to rely on specified statutory grounds (for example, serious rent arrears or certain landlord-circumstance grounds). The grounds, notice periods and procedure differ from the old no-fault route, and many are discretionary — meaning the court weighs whether it is reasonable to order possession. If your matter began as a Form 6A but the notice has lapsed or post-dates abolition, the section 8 grounds are the route to consider instead.

The accelerated possession procedure (Form N5B)

Where a valid section 21 notice was relied on inside the transitional window, possession was pursued using the accelerated possession procedure, started on Form N5B. Its key features:

• Paper-based. The court can usually decide on the documents without a hearing, which is why it is “accelerated” compared with the standard section 8 procedure.
• No money claim. N5B is for possession only — it does not include a claim for rent arrears. A separate claim is needed for any money owed.
• Evidence attached. The claim must exhibit the tenancy agreement, the Form 6A notice, proof of service, and the documents proving the validity conditions (deposit protection, EPC, gas safety, How to Rent).
• A court fee applies. Check the current issue fee before filing.
• Tenant’s reply. The tenant has a short period to file a reply raising any defence — most commonly that the Form 6A is invalid. Check the current response period.

Crucially for 2026: accelerated possession on a pre-1 May private-sector section 21 notice was only available until the earlier of the notice’s expiry and 31 July 2026 (breathing-space extensions aside). After that, the notice falls away, the tenancy continues as an assured periodic tenancy, and the claim must be rebuilt on section 8 grounds — see our Form N5B guide for the full transitional rules.

Common mistakes

• Assuming section 21 still works. It does not, for new notices. The most serious error in 2026 is serving a fresh Form 6A — it is a nullity.
• Missing the transitional deadline. A valid pre-1 May 2026 notice had to be acted on in time: the claim had to be issued by the earlier of the notice’s expiry and 31 July 2026. A claim started after that is out of time.
• Forgetting a document. No EPC, no gas safety record, or the wrong How to Rent version will sink the notice — and the claim.
• Deposit slips. Late protection or missing prescribed information remains the classic killer.
• Wrong dates. Serving inside the first four months, or miscalculating the notice expiry, invalidates the notice.
• Using N5B for arrears. The accelerated route recovers possession, not money — pursue rent separately.
• Relying on an old form version. Always verify you used the version of Form 6A in force on the date of service.

Frequently asked questions

Can a landlord still serve a Form 6A in 2026?

Not for a private tenancy. Section 21 was abolished for England’s private rented sector on 1 May 2026, so a new private-sector Form 6A is a nullity — possession must be sought on section 8 grounds using Form 3A. The exceptions: social housing landlords (private registered providers) can still serve Form 6A until the reforms reach their tenancies in 2027 at the earliest, and a private-sector notice validly served before 1 May 2026 had a transitional life under those rules.

I was served a Form 6A before the law changed — is it still valid?

Possibly. A notice validly served before 1 May 2026 could still be relied on, but only if the landlord asked the court to issue proceedings by the earlier of the notice’s expiry date and 31 July 2026 (unless a tenant’s breathing space extended the deadline), and only if every section 21 validity condition was met when the notice was served. If either fails, the notice cannot support a possession order.

What is the minimum notice period on a Form 6A?

The statutory minimum was generally two months from when the notice was given, expiring on the correct date. Because dates are decisive, always check the current figure and calculate the expiry carefully against your own facts.

What makes a Form 6A invalid?

The usual culprits are an unprotected deposit, missing prescribed information, no EPC, a missing or expired gas safety certificate, the wrong How to Rent guide, service in the first four months, service during a protected improvement-notice period, the wrong form version, or a miscalculated notice period. Any one can be enough.

What is Form N5B?

Form N5B starts the accelerated possession procedure — the paper-based route used where a valid section 21 notice is relied on. The court can usually decide without a hearing. It recovers possession only, not rent arrears, and a court fee applies. Check the current fee.

What can I do if I receive an accelerated possession claim?

Read the claim and the deadline carefully, then test the Form 6A against every validity condition. If any was not met, that is the heart of your defence. File your reply within the court’s timetable — late or absent replies are a frequent reason tenants lose.

Does any of this apply in Wales?

No. Wales has a separate system under the Renting Homes (Wales) Act 2016, with different notices and procedures. Form 6A and section 21 are England-only.
