Since Section 21 was abolished on 1 May 2026, possession claims for assured tenancies in England's private rented sector generally proceed through Section 8 of the Housing Act 1988. There is no longer a route that avoids giving a reason.

That makes ground selection the single most consequential decision in the possession process. Choose the wrong ground and the notice is invalid. Give the wrong notice period and the claim fails at the first hurdle. Rely on a discretionary ground without evidence and the court may decline.

This guide covers the grounds available to private landlords and letting agents in England, the notice period each requires, and the procedural traps that cause otherwise valid claims to fail.

Scope: this covers assured tenancies in England's private rented sector. Housing is devolved, so Scotland, Wales and Northern Ireland operate separate regimes. Different rules apply to social housing assured tenancies provided by Private Registered Providers (PRPs); the Renters' Rights Act changes will apply to those tenancies from 2027.

How Section 8 Possession Works

The process has three stages:- 

1. First
   Identify a Ground -> The ground must genuinely apply to your circumstances, and you must be able to evidence it.

2. Second
   Serve Notice Using Form 3A -> The prescribed assured tenancy form, giving at least the required notice period. You can rely on more than one ground in a single notice, and you should set out the grounds relied on and include supporting evidence . For Example - Bank statements showing unpaid rent. 

3. Third
   Apply to Court -> If the tenant does not leave when the notice expires.

Two practical points on service and timing. Keep proof that notice was given, either by completing a certificate of service (Form N215) or by writing "served by [name] on [date]" on the notice itself. And note the deadline: for a Section 8 notice given on or after 1 May 2026, you will usually have up to 12 months to apply to court. Miss that and you start again.

Deposit Compliance Is a Precondition

The court will only grant a possession order if one of the following applies:

• the deposit was returned to the tenant in full, or with agreed deductions

• the tenant brought a court challenge on deposit protection and the case has been decided, settled or withdrawn

• you still hold the deposit and it is in a government-approved scheme

Where you still hold the deposit at the hearing, you must prove it is protected in an approved scheme, that you are following the scheme's rules, and that you gave the tenant the required prescribed information.

These deposit requirements do not apply to Grounds 7A and 14 for anti-social behaviour.

Once the Private Rented Sector Database is in force, registration is expected to become a further precondition, with the same anti-social behaviour exception.

Mandatory Versus Discretionary Grounds

This distinction determines how much control you have over the outcome.

Mandatory Grounds: if your evidence proves the ground is met, the court must grant a possession order. You can apply as soon as the notice period ends.

Discretionary Grounds: you must prove the ground, and the court then decides whether it is reasonable to grant possession, taking the evidence and circumstances into account. A proven ground does not guarantee possession.

The practical consequence is that discretionary grounds require far more preparation. You are not just proving a fact you are persuading a judge that possession is a proportionate response.

Mandatory Grounds and Their Notice Periods

The grounds most relevant to private landlords:

This is not the complete list. Further mandatory grounds cover superior leases (2ZA–2ZD), supported accommodation (5E–5G), agricultural workers (5A), ministers of religion (5), rent-to-buy (1B) and provisions restricted to Private Registered Providers and social landlords. All grounds and notice periods are set out in GOV.UK's grounds for possession guidance for landlords and letting agents.

Ground 1: Landlord or Family Moving In

Available where you or a close family member need to move into the property.

It cannot be used in the first 12 months of a new tenancy. You may serve notice during that period, but the notice cannot expire before the twelve months has ended which in practice means giving more than four months' notice if you serve early.

A detail worth noting: you or your family member can only move in after the tenant has been evicted, not before.

Ground 1A: Sale of the Property

Ground 1A is the mandatory ground available where the landlord intends to sell the property.

Same structure as Ground 1: four months' notice, unavailable in the first twelve months, and notice served early cannot expire inside the protected period. GOV.UK's own worked example makes the arithmetic clear a landlord four months into a tenancy who wants to sell may need to give considerably more than four months' notice, because expiry must fall outside the protected period.

One important exclusion: Ground 1A cannot be used where the tenant has an assured tenancy created before 1 May 2026 that was not an assured shorthold tenancy. These are sometimes called assured "lifetime" tenancies. Most social landlords also cannot use this ground.

Ground 6: Redevelopment

Available where you need to demolish or substantially redevelop and the tenant cannot remain in situ.

Note the difference from Grounds 1 and 1A: GOV.UK states that you usually cannot use this ground in the first 6 months of a tenancy, not twelve though exact requirements vary by circumstance. Four months' notice applies.

Social landlords using this ground may need to provide suitable alternative accommodation, unless notice of intention to use Ground 6 was given before the tenancy started.

Ground 8: Serious Rent Arrears

The highest-volume mandatory ground, and the one with the most exacting requirements.

The tenant must owe at least three months' rent where rent is paid monthly, or at least 13 weeks' rent where it is paid weekly or fortnightly. The notice period is four weeks.

Three conditions make this harder than it looks:

The threshold must be met twice. Arrears must reach the required level both on the day notice is served and at the hearing date.

Payment can defeat the ground. If the arrears fall below the statutory threshold by the hearing, Ground 8 will no longer be made out on that basis.

Universal Credit delays are excluded. Where the shortfall exists because the tenant has not received Universal Credit, that amount does not count toward the threshold.

The standard defensive approach is to plead Ground 8 alongside Grounds 10 and 11, so a claim that fails the mandatory threshold retains a discretionary route.

Before serving notice on arrears grounds, it is also worth checking whether managed payments are available. Where a tenant claims Universal Credit or Housing Benefit, rent can in some cases be paid directly to the landlord which may resolve the situation without possession proceedings.

Ground 4A: Student HMOs

Narrow but useful for student landlords. It applies to HMOs let to full-time students where the property is needed for a new cohort in line with the academic year, with possession falling between 1 June and 30 September.

Two conditions catch people out: you must have given advance notice that you intend to rely on this ground, and you cannot use it if the tenancy was agreed more than six months before it started. Four months' notice applies.

Grounds 7A and 14: Anti-Social Behaviour

These work differently from every other ground, and the difference is widely misreported.

You do not need to give a notice period you can apply to court immediately after serving notice. However, the court cannot make a possession order until 14 days have passed from the date notice was given.

That distinction matters. "No notice period" is not the same as "immediate possession." The 14-day floor applies regardless.

Ground 7A (mandatory) covers conviction for a listed offence, breach of an order preventing anti-social behaviour, or a closure order barring access for more than 48 hours. Ground 14 (discretionary) covers behaviour causing or likely to cause nuisance or annoyance, including conduct near the property rather than in it.

Common Discretionary Grounds and Their Notice Periods

Other discretionary grounds apply in specific circumstances, including supported accommodation (Ground 18) and social housing.

Ground 10 covers any level of arrears useful where the tenant is behind but below the Ground 8 threshold. Ground 11 covers repeated late payment even where the account is currently clear.

Ground 12 is the general breach ground for breaches of tenancy terms unrelated to rent, subject to the specific facts and the terms of the tenancy agreement.

Evidence: What Actually Decides Discretionary Claims

This is where most claims are won or lost, and where the shift from the old regime bites hardest.

Under Section 21, a landlord did not have to prove anything about the tenant's conduct. Under Section 8 discretionary grounds, the court considers whether it is reasonable to make a possession order, taking the evidence and circumstances of the case into account.

What helps:

• Contemporaneous records. Notes made at the time carry weight. A summary written once a dispute arose carries much less.

• Documented attempts to resolve the issue. Where appropriate, records of warnings, requests to remedy a breach and opportunities given to put things right can help demonstrate how the situation developed and how the landlord responded. This is operational good practice rather than a universal statutory requirement, but it is the kind of material a court can weigh.

• A complete communication trail. What was said, when, by whom, and how the tenant responded.

• Proportionality. The seriousness and persistence of the issue against the consequences of eviction.

For arrears claims, that means a clean rent ledger, records of contact about the arrears, and evidence of any payment arrangement offered or agreed. For breach and anti-social behaviour claims, it means dated incident records, correspondence and any third-party evidence such as neighbour complaints or police reports.

The operational implication is straightforward: evidence has to be created as events happen, not assembled when you need it. A property team that logs communications, maintenance issues and arrears contact as a matter of routine has a case file already built. One relying on scattered email threads and individual memory does not and discovers this at the point it matters most. Systems that capture service requests and task management as structured records rather than ad hoc messages make that trail available by default.

Common Mistakes That Invalidate a Notice

Wrong notice period. Where you rely on multiple grounds, the longest applicable period generally governs — with specific exceptions for the anti-social behaviour grounds.

Deposit non-compliance. Protection alone is not enough. The scheme's rules must have been followed and prescribed information given. Check before serving, not at the hearing.

Using the protected period wrongly. Grounds 1 and 1A cannot expire inside the first twelve months. Serving four months' notice at month five does not work.

Miscalculating Ground 8 arrears. The threshold must be met at service and hearing, and Universal Credit shortfalls are excluded.

Assuming "no notice period" means immediate. Grounds 7A and 14 still carry a 14-day floor before the court can order possession.

Missing the 12-month application window. A Section 8 notice given on or after 1 May 2026 usually allows up to 12 months to apply to court. A notice left to expire is wasted.

No proof of service. Complete an N215 or endorse the notice. Without it, service can be disputed.

Relying on a discretionary ground without a file. Proving the ground is only half the task.

Restrictions After Using Grounds 1 and 1A

MHCLG guidance states that landlords cannot market or re-let a property for twelve months after using the moving-in or selling grounds. The stated purpose is to prevent misuse of those grounds.

There is a limited exception for shared owners using Ground 1A who can demonstrate a genuine attempt to sell. Landlords of tenancies created before 1 May 2026 needed to give tenants written notice by 31 May 2026 to claim it. Shared owners should read GOV.UK's dedicated guidance rather than assume the exception applies.

There is also an enforcement dimension. Knowingly or recklessly misusing a possession ground is an offence, and can attract a rent repayment order.

The practical risk is real: use Ground 1A, have the sale fall through, and you hold an empty property you are restricted from letting for the remainder of the twelve months.

Realistic Timescales

Two timing points matter for planning.

The notice period is not the total time to recover possession. Where the tenant does not leave, a court application, a hearing and if necessary enforcement all follow. Possession is best planned as a process measured in months.

At the same time, a Section 8 notice does not stay live indefinitely. For notices given on or after 1 May 2026, you will usually have up to 12 months to apply to court. That gives room to negotiate, but it is a deadline.

Where a payment arrangement, managed payments or a negotiated surrender is achievable, it is almost always faster than court.

Conclusion

Section 8 replaced a procedural shortcut with an evidential process. That is the whole of the change, and everything else follows from it.

Ground selection now determines the notice period, the standard of proof and whether the court has discretion to refuse. Protected periods restrict when the sale and moving-in grounds can be used. Arrears thresholds must hold at two separate points in time. Deposit compliance has to be demonstrable, not merely assumed. Discretionary grounds turn on a file that has to have been built before the dispute arose.

None of that makes possession unobtainable. It makes it deliberate. Landlords and agents who identify the correct ground early, calculate the notice period carefully, verify deposit compliance and maintain records as a matter of routine are recovering properties without particular difficulty. Those improvising at the point of crisis are finding out how unforgiving the process has become.

Frequently Asked Questions

1. What Are the Section 8 Grounds for Possession in England?
Section 8 grounds are the legal reasons a landlord can seek possession of a property let on an assured tenancy. Mandatory grounds - including Ground 1 (landlord moving in), Ground 1A (sale), Ground 6 (redevelopment) and Ground 8 (serious rent arrears) - require the court to grant possession where the evidence proves the ground is met. Discretionary grounds - including Grounds 10 and 11 (arrears), Ground 12 (breach of tenancy) and Ground 14 (anti-social behaviour) - leave the court to decide whether possession is reasonable.

2. How Much Notice Must I Give Under Section 8?
It depends on the ground. Four months applies to Grounds 1, 1A, 2, 4A and 6. Four weeks applies to the arrears grounds 8, 10 and 11. Two months applies to Grounds 5C, 7 and 9. Two weeks applies to Grounds 7B, 12, 13, 15 and 17. Grounds 7A and 14 allow immediate application to court, but no possession order can be made until 14 days after notice was given. Where multiple grounds are used, the longest applicable period generally governs.

3. How Much Rent Arrears Are Needed for Ground 8?
At least three months' rent where rent is paid monthly, or 13 weeks' rent where it is paid weekly or fortnightly. The threshold must be met both when notice is served and at the hearing. If the arrears fall below the threshold before the hearing, Ground 8 will no longer be made out. Arrears caused by unreceived Universal Credit are excluded from the calculation.

4. Can I Evict a Tenant to Sell the Property in England?
Yes, using Ground 1A with four months' notice. It cannot be used during the first twelve months of a tenancy, and notice served earlier cannot expire before that period ends. After using it, restrictions apply on marketing or re-letting the property for twelve months. It is also unavailable against certain assured tenancies created before 1 May 2026 that were not assured shorthold tenancies.

What Happens if My Tenant Does Not Leave After the Notice Expires?

You must apply to the county court for a possession order usually within 12 months of giving the notice. A landlord should not attempt to remove a tenant without following the lawful possession and enforcement process; unlawful eviction and harassment can constitute criminal offences. The court will consider whether the ground is proven and, for discretionary grounds, whether possession is reasonable. If an order is granted and the tenant still does not leave, enforcement is through county court bailiffs or High Court enforcement officers.
