Understanding the purpose of a Section 8 notice.
A Section 8 notice is a notice seeking possession served under the Housing Act 1988. It applies where a tenant has breached the tenancy agreement or another statutory ground for possession applies under an assured or assured shorthold tenancy.
A Section 8 notice can be served during both fixed-term and periodic tenancies. In a fixed term, it allows a landlord to act during the tenancy where a qualifying ground arises. In a periodic tenancy, which runs on a rolling weekly or monthly basis, it may be served at any time provided a valid statutory ground exists. The form of the tenancy does not determine whether Section 8 can be used - the availability of Section 8 depends on the existence of a recognised ground for possession.
This position will become central following the implementation of the Renters Rights Act 2025. The Act will abolish assured shorthold tenancies and remove Section 21 no-fault evictions. Once implemented, all private residential tenancies will operate as assured periodic tenancies, and landlords will only be able to regain possession by establishing a statutory ground. As a result, Section 8 will become the primary statutory route for recovering possession.
A Section 8 notice informs the tenant that the landlord intends to apply to the court for possession once the notice period expires. It does not end the tenancy and does not permit eviction without a possession order. Because the notice forms the legal foundation of any possession claim, the court will assess whether it complies with all statutory requirements before considering the substance of the case.
What makes a Section 8 notice invalid?
A Section 8 notice is invalid where it fails to meet statutory and procedural requirements. Courts apply a strict approach, particularly where errors affect the tenant’s ability to understand the case against them or respond properly.
Common reasons a notice is deemed invalid include:
- Use of the wrong prescribed form;
- Incorrect notice period;
- Errors in dates or calculation of weeks’ notice;
- Failure to specify valid grounds for possession;
- Inaccurate rent arrears figures;
- Missing or incorrect landlord’s details;
- Failure to identify the correct property address;
- Service that is not carried out correctly.
Where a notice is deemed invalid, the possession proceedings will usually be dismissed. The landlord must then serve a new notice and restart the eviction process.
Failure to use the prescribed form
A Section 8 notice must be served using the correct prescribed form. This is currently Form 3 - Notice seeking possession of a property let on an assured tenancy or an assured agricultural occupancy.
If a landlord uses an outdated version of the prescribed form, alters mandatory wording or issues a notice in a non-compliant format, the notice may be deemed invalid. Courts take a strict view on compliance with prescribed forms, as they are intended to give tenants clear and consistent information.
Using the wrong form or a modified template is one of the most common reasons a Section 8 notice fails at court.
Incorrect notice period
An incorrect notice period is another frequent cause of invalidity. Each ground for possession under Section 8 carries its own notice period, set out in the Housing Act and amended by subsequent legislation.
Where more than one ground is relied upon, the notice period must match the longest applicable period, unless a shorter period applies due to specific grounds such as serious anti-social behaviour.
Examples of notice period errors include:
- Giving two weeks’ notice where four weeks or two months’ notice is required;
- Miscalculating the notice period by selecting the wrong expiry date;
- Failing to account for changes introduced by the Renters Rights Act.
If the notice period is incorrect, the court will not grant possession, regardless of the strength of the underlying ground.
Incorrect dates and clerical errors
A Section 8 notice must state the date after which court proceedings may begin. Incorrect dates can invalidate the notice where they misstate how much notice the tenant receives.
Clerical errors may invalidate a notice where they cause genuine confusion for a reasonable recipient. Examples include:
- Stating an expiry date that does not reflect the notice period given;
- Internal inconsistencies between dates and notice length;
- Obvious calculation errors that reduce the notice period.
Minor typographical errors will not always invalidate a notice, but where the error affects how much notice is given or misleads the tenant, the court is likely to find the notice invalid.
Failure to specify valid grounds for possession
A Section 8 notice must clearly identify the ground for possession relied upon. Each ground must be correctly cited and accompanied by sufficient detail.
Common errors include:
- Relying on a ground that does not apply to the tenancy type;
- Citing mandatory grounds without meeting statutory thresholds;
- Failing to provide particulars explaining how the ground is made out;
- Relying on a rent ground where figures are inaccurate.
Where the landlord wishes to rely on more than one ground, each must be listed clearly. Vague or incomplete grounds increase the risk of legal challenges and dismissal of the case.
Rent arrears errors
Rent arrears cases are among the most common Section 8 claims, particularly under Ground 8, which is a mandatory ground.
A notice may be deemed invalid where:
- Rent arrears figures are incorrect;
- Payments are not properly credited;
- The threshold for mandatory grounds is not met;
- Arrears fall below the threshold by the court hearing.
Under Ground 8, rent arrears must meet the statutory level at both the date the notice is served and the court hearing. If the figures are wrong, the court cannot grant possession under that ground.
Inaccurate rent schedules and misstatements of unpaid rent frequently result in failed possession claims.
Errors in the tenancy agreement details
The Section 8 notice must align with the tenancy agreement. Errors arise where:
- The tenancy type is misstated;
- The fixed term or periodic tenancy status is wrong;
- Tenant names do not match the tenancy agreement;
- The notice refers to obligations not contained within the agreement.
If the court cannot reconcile the notice with the tenancy agreement, it may conclude that the notice is defective and cannot support possession proceedings.
Incorrect property address
The property address must be stated accurately and in full. Where a landlord owns multiple rental properties, mistakes are common.
Errors include:
- Incomplete addresses;
- Incorrect flat numbers;
- Use of an old address following renumbering or conversion.
If the notice does not clearly identify the property to which it relates, the tenant may argue that it is unclear which tenancy is affected. Courts often accept this argument, rendering the notice invalid.
Missing or incorrect landlord’s details
A valid Section 8 notice must include the landlord’s details or those of the landlord’s agent acting on their behalf.
Issues arise where:
- The landlord’s address is missing or incorrect;
- The landlord’s agent is named without authority;
- Contact details are incomplete or inaccurate.
The tenant must be able to identify who is seeking possession and how to respond. Failure to provide the correct landlord’s details undermines the validity of the notice.
Failure to serve the notice correctly
A Section 8 notice must be served correctly in accordance with the tenancy agreement or statutory rules.
Accepted service methods commonly include:
- Personal delivery;
- Recorded delivery;
- First-class post.
Service errors include:
- Failing to allow sufficient time for delivery;
- Serving by an unauthorised method;
- Lack of proof that the tenant received the notice.
Where service cannot be proven, the court may find that the notice was not served correctly and therefore cannot support a possession claim.
Deposit protection failures and validity
Although deposit protection issues more commonly affect Section 21 notices, they can still undermine a Section 8 case in certain circumstances.
Where deposit protection obligations are linked to the tenancy agreement and the landlord’s conduct is challenged, courts may scrutinise compliance more closely. While a failure in deposit protection does not automatically invalidate a Section 8 notice, it can weaken the landlord’s overall position during court proceedings.
How to check if a Section 8 notice is valid
Before issuing possession proceedings, landlords should check:
- The correct prescribed form has been used;
- The notice period matches the grounds relied upon;
- Dates and calculations are accurate;
- Rent arrears figures are correct and evidenced;
- Grounds for possession are clearly explained;
- The tenancy agreement supports the grounds relied upon;
- The notice has been served correctly.
A careful review at this stage reduces the risk of the notice being deemed invalid later.
How long does a Section 8 notice remain valid?
A Section 8 notice does not last indefinitely. Proceedings must usually be started within 12 months of service, although practical issues often arise sooner.
Where circumstances change - such as rent arrears reducing or the tenancy becoming periodic - the landlord may need to serve a new notice to reflect the current position accurately.
Delays increase the likelihood that a notice will no longer support a possession claim.
What makes a possession order invalid?
A possession order may be challenged where:
- The underlying Section 8 notice was invalid;
- The court was misled by inaccurate information;
- Procedural requirements were not followed;
- The tenant did not receive proper notice.
Where a possession order is set aside following an appeal case or review, the landlord may need to restart the process entirely.
Legal challenges raised by tenants
Tenants frequently raise legal challenges based on:
- Incorrect notice period;
- Inaccurate rent arrears;
- Failure to use the prescribed form;
- Service defects.
Where the tenant attends the court hearing, these arguments are commonly raised by a duty solicitor. Even where the tenant does not attend, the court may consider validity issues of its own motion.
The impact of the Renters Rights Act
The Renters Rights Act introduces changes affecting notice periods, grounds for possession and thresholds for rent arrears. Landlords must reflect these changes accurately when serving a Section 8 notice.
Failure to apply the updated legal requirements may result in the notice being deemed invalid, even where it would previously have been acceptable.
Serving a new notice
Where a Section 8 notice is deemed invalid, the usual remedy is to serve a new notice. This resets the notice period and delays the eviction process.
Landlords should address all defects before serving a new notice to avoid repeat errors and further delays.
Regaining possession lawfully
To regain possession lawfully, landlords must:
- Serve a valid Section 8 notice;
- Issue a possession claim using the correct claim form;
- Attend the court hearing with accurate evidence;
- Obtain a possession order;
- Enforce the order through the county court if required.
Shortcuts or procedural errors increase the risk of dismissal or enforcement action against the landlord.
When professional advice is appropriate
Professional advice is appropriate where:
- Rent arrears are complex or disputed;
- More than one ground is relied upon;
- The tenancy history is unclear;
- Previous notices have failed;
- Enforcement action is anticipated.
- Errors at the notice stage often prove more costly than addressing issues early.

How will landlords evict tenants without Section 21?
Once Section 21 is removed, landlords will rely exclusively on the statutory grounds for possession set out in Section 8. The Renters’ Rights Act updates these grounds to reflect situations where regaining possession is necessary and justified, ensuring landlords can still recover their properties when circumstances change.
The new and strengthened grounds for possession
To sell your property - new mandatory Ground 1A:
A new ground will allow landlords to recover possession when they intend to sell the property.
- Notice period: four months.
- Restrictions: this ground cannot be used within the first 12 months of a tenancy. After relying on it, the property cannot be re-let or advertised for 12 months, preventing it from being used as a substitute for a no-fault eviction.
For a landlord or family member to move in - revised Ground 1:
The existing ground for a landlord or their close family member to live in the property remains but with tighter controls.
- Notice period: four months.
- Restrictions: it cannot be used during the first 12 months of a tenancy, and the property cannot be re-let on the open market for 12 months after possession is obtained.
Dealing with rent arrears - Grounds 8 and 10:
The rent arrears framework has been updated to distinguish between temporary financial issues and sustained non-payment.
- Serious rent arrears (Ground 8): now requires at least three months of arrears both at the notice stage and at the hearing. Arrears caused by delays to Universal Credit will not count.
- Notice period: increased to four weeks.
- Any rent arrears (Ground 10): remains a discretionary ground, now with a four-week notice period.
Tackling anti-social behaviour - Grounds 7A, 14 and 14ZA
The Act widens the tools available to landlords dealing with disruptive or dangerous behaviour.
- Serious anti-social behaviour (Ground 7A): notice requirements have been reduced, allowing landlords to issue a claim immediately.
- Riot-related offences - new mandatory Ground 14ZA: provides for immediate possession if a tenant is convicted of a serious offence during a riot.
- General anti-social behaviour (Ground 14): the definition of anti-social conduct has been expanded, giving the court wider discretion.
AST Assistance advises landlords on the strengthened Section 8 regime and how each ground should be used in practice. For guidance on preparing evidence or assessing which grounds apply to your circumstances, get in touch.
What are the new rules for landlords?
The Renters' Rights Act introduces more than just changes to eviction. Landlords must prepare for a new tenancy system and new regulatory bodies.
A new tenancy system
All tenancies will become periodic from the outset, providing more security for tenants. For landlords, this means the end of a fixed-term tenancy. Rent increases will be limited to once per year, and you must use a statutory Section 13 notice, giving the tenant two months' notice of any change. Tenants will be able to challenge excessive increases at a tribunal.
Mandatory landlord ombudsman
Expected in late 2026, all private landlords will be legally required to join a single, government-approved Ombudsman scheme. This body will resolve disputes between landlords and tenants without needing to go to court, and it will have the power to order landlords to pay compensation of up to £25,000. Failure to join will result in significant fines.
The private rented sector database
Also expected in late 2026, a new national database will require all landlords to register themselves and their properties. This will help local authorities track down criminal landlords and allow tenants to see if their landlord is compliant with their legal obligations. An unregistered landlord may be unable to use any Section 8 grounds for possession.
Other key changes
- Ban on "rental bidding wars": you will be prohibited from encouraging tenants to bid against each other for rent.
- Right to request a pet: tenants will have a legal right to request a pet, which a landlord cannot unreasonably refuse. You will, however, be able to require the tenant to take out pet insurance.
- End to discrimination: it will be illegal to have blanket bans on renting to tenants with children or those who receive benefits.
The eviction timeline after a Section 21 Notice expires
For landlords who serve a Section 21 notice before the commencement date, the process that follows will continue under the existing rules. If a tenant stays beyond the notice period, you cannot enter the property or change the locks yourself. You must obtain a possession order through the court. These procedures will remain available for any valid Section 21 notice served before 1 May 2026. After this date, the Renters’ Rights Act removes Section 21 entirely, and the timeline for possession will operate solely under the strengthened Section 8 grounds.
Step 1: The possession claim
When the notice period ends, you may issue your claim under the current system.
- Accelerated possession claim: this remains the standard route for Section 21 cases. Claims are usually processed on paper, without a hearing, as long as the documents are in order and the tenant does not raise a defence. Timeframes generally fall between four and eight weeks, though backlogs may extend this.
- Standard possession claim: required when you are also claiming rent arrears. A hearing is unavoidable, and court listing times can range from six to ten weeks or more.
Once Section 21 is abolished, accelerated possession will no longer exist. All future claims will be grounded in the revised Section 8 regime, which may alter timescales depending on the evidence required.
Step 2: The possession order
If your claim succeeds, the court will issue a possession order requiring the tenant to vacate. The usual timeframe is 14 days. Judges retain discretion to extend this to a maximum of 42 days where the tenant can demonstrate exceptional hardship. This structure remains unchanged under the transitional rules, but once landlords move exclusively to Section 8, the court will assess each case based on the specific ground relied upon and the supporting evidence.
Step 3: Enforcement if the tenant refuses to leave
If the tenant stays past the date in the possession order, enforcement becomes necessary.
- County Court bailiffs: the standard route for enforcement. Wait times can vary considerably, from four weeks to more than nine months, depending on local availability.
- High Court Enforcement Officers (HCEOs): you may apply to transfer enforcement to the High Court. Although more expensive, this option is usually quicker, often taking between two and three weeks.
These enforcement routes will remain in place after Section 21 is abolished, but landlords will reach this stage through Section 8 grounds rather than a no-fault notice. The Renters’ Rights Act aims to make these grounds more workable, particularly around anti-social behaviour and persistent arrears, but landlords will need stronger evidence and more structured record-keeping.
Overall, from the expiry of a Section 21 notice to regaining possession with bailiff involvement, the timeline typically ranges from three and a half to five and a half months, with many cases taking longer. The Renters’ Rights Act does not shorten these timeframes, so preparation and early action remain central for landlords using the transitional system.
Experts in tenancy law, such as AST Assistance, can help you understand eviction timelines and your rights both in the lead-up to the abolition of Section 21 and afterwards.
Plan ahead with AST Assistance
The end of the Section 21 process represents a major shift for landlords across the private rented sector. Although you may still serve a Section 21 notice today, the window is narrowing, and accuracy matters more than ever. A notice that fails for procedural reasons risks placing you on the wrong side of the commencement date, forcing you into the new statutory grounds system sooner than planned.
Landlords who act now place themselves in a stronger position. You may need to progress an eviction under the existing regime, or you may be preparing to rely on the reformed Section 8 grounds once Section 21 is abolished. In either scenario, specialist guidance will help you make sound decisions, gather the correct evidence, and avoid avoidable delays.
AST Assistance provides focused legal support to landlords facing possession issues. We work through the process with you, advising on notice validity, drafting compliant paperwork, preparing evidence, and guiding you through court proceedings where required. Our team understands the operational pressures landlords face and offers clear, precise advice designed to protect your position.
