Section 8 grounds for possession in 2026: the letting agent's working reference

The short version

Section 21 was abolished on 1 May 2026. There is no longer a no-fault possession route in England. Every Section 21 notice in flight on commencement either has to convert to a Section 8 ground or is dead. Every new possession action is a Section 8 action, and the grounds list itself was rewritten by the Renters' Rights Act — two new mandatory grounds for landlord occupation and sale, a new mandatory ground for persistent rent arrears, longer notice periods on most grounds, and a re-letting restriction on the new occupation and sale grounds.

For a letting agent, possession is now a documentation discipline. The court will not accept a Section 8 claim on the agent's word. It will check the database registration, the gas safety, the EICR, the EPC, the deposit protection, the prescribed information, and the specific evidence the ground requires. Anything missing is a dismissed claim and another four to six months of arrears or anti-social behaviour before a second attempt.

This is the working reference. Every ground, what it requires, the notice period, the evidence agents need on file, and the operational traps showing up in the first week of commencement.

For the broader operations changes the Act triggered, see the day-one operations checklist. For PRS Database registration, which gates almost every Section 8 ground, see the database registration rollout plan.

What changed on 1 May 2026

Five things matter for possession work:

1. 1Section 21 is gone. No-fault possession does not exist. Pre-commencement Section 21 notices already served continue under transitional rules; new ones cannot be issued.
2. 2All assured shorthold tenancies converted to assured periodic tenancies. There are no fixed terms anymore. The tenancy continues month-to-month until ended on a Section 8 ground or by the tenant.
3. 3The Section 8 grounds list expanded. Two new mandatory grounds (1A, 1B) for landlord occupation and sale. New mandatory ground 8A for persistent rent arrears. Tightened anti-social behaviour grounds.
4. 4Notice periods lengthened. Most mandatory grounds now require four months instead of two. Rent arrears grounds remain at four weeks. Anti-social behaviour can still be immediate.
5. 5PRS Database registration gates Section 8. A property without a current database registration cannot have most Section 8 grounds served on it. The notice will be invalid.

The combined effect is that possession is slower, requires more evidence, and is harder to recover from if anything is missing. Agents who treated possession as paperwork to be drafted on demand are finding that paperwork has to be assembled, dated, and audit-trailed months in advance.

Mandatory vs discretionary — why it matters operationally

Every Section 8 ground is either mandatory or discretionary.

• Mandatory means: if the ground is made out on the evidence, the court must grant possession. There is no judicial discretion. These are the grounds agents should be aiming for wherever the facts allow.
• Discretionary means: even if the ground is made out, the court can decline possession if it is not reasonable to grant it. The tenant's circumstances, the landlord's conduct, and the property's condition all become relevant.

For an agent serving notice, the practical implication is that mandatory grounds are far more reliable. A discretionary claim can be defeated at hearing even on watertight evidence if the judge accepts the tenant's mitigation. Where two grounds could apply, serve both — mandatory and discretionary in the alternative — and the mandatory ground does the heavy lifting if the evidence holds.

The grounds — working reference

Below is every Section 8 ground operationally relevant to a letting agent in 2026, with the notice period, mandatory or discretionary status, and the evidence required. This is a working reference, not legal advice — always run the specific facts of a possession case past a qualified housing solicitor before serving.

Ground 1 — Prior owner-occupation (mandatory, 4 months)

The landlord previously occupied the property as their only or principal home, and now requires it back to occupy as their only or principal home, or for a spouse to occupy. Notice of the possibility of Ground 1 must usually have been given in writing before the tenancy started.

Evidence on file: prior occupation evidence (council tax, electoral roll, utility bills in landlord's name during prior period), pre-tenancy notice in writing if served, statutory declaration of intent to occupy.

Ground 1A — Landlord or close family to occupy (mandatory, 4 months) — NEW

The landlord, or a close family member specified in the schedule, intends to occupy the property as their only or principal home. Cannot be used in the first four months of a tenancy. After possession, the property cannot be re-let or marketed for twelve months.

Evidence on file: statutory declaration of intent to occupy, identification confirming the family relationship if applicable, evidence of the planned move (mortgage application, schools enrolment, employment in the area).

Operational trap: the twelve-month re-let restriction is a banning offence. Flag the property in the system the day possession is recovered.

Ground 1B — Sale of dwelling (mandatory, 4 months) — NEW

The landlord intends to sell the property with vacant possession. Cannot be used in the first four months of a tenancy. After possession, the property cannot be re-let or marketed for twelve months.

Evidence on file: estate agent instruction letter, marketing materials, statutory declaration of intent to sell.

Operational trap: if the sale falls through, the twelve-month restriction on re-letting still runs. Many landlords will return to the agent in month six wanting to re-let. The answer is no. Document the conversation.

Ground 2 — Mortgagee sale (mandatory, 2 months)

The property is subject to a mortgage that pre-dates the tenancy, the lender requires possession to enforce the mortgage, and notice of the possibility of Ground 2 was given before the tenancy.

Evidence on file: mortgage deed, lender's possession claim or formal demand, pre-tenancy notice.

Ground 4 / 4A — Student lets and purpose-built student accommodation (mandatory, 2 weeks)

For lets to students by an educational institution or specified provider, where the property is required for the next academic year's intake.

Evidence on file: institution's letting policy, prior notice that the let was for a fixed academic period, evidence of the next intake.

Ground 5 — Minister of religion (mandatory, 2 months)

The property is required for occupation by a minister of religion as a residence from which to perform duties.

Ground 6 — Demolition or redevelopment (mandatory, 4 months)

The landlord intends to demolish or substantially reconstruct the property and cannot reasonably do so with the tenant in occupation. Strict requirements about ownership timing — the landlord must not have purchased the property after the tenancy started.

Evidence on file: planning permission or evidence of intent, contractor quotes, ownership history.

Ground 6A — Compliance with enforcement action (mandatory, 4 months)

Possession is required to comply with an enforcement notice, prohibition order, or similar from the local authority.

Evidence on file: the enforcement notice itself.

Ground 7 — Death of tenant (mandatory, 2 months)

The tenant has died and there is no statutory succession.

Ground 7A — Anti-social behaviour, mandatory (mandatory, varies — can be immediate)

Tenant or someone living with them has been convicted of a serious offence, breached an injunction, or been the subject of a closure order. The notice period depends on the trigger — in the most serious cases possession can be sought without prior notice.

Evidence on file: the conviction, order, or closure notice. Police reports do not satisfy this ground — there must be a determination by a court.

Ground 7B — No right to rent (mandatory, 2 weeks)

The Home Office has notified the landlord that the tenant has no right to rent.

Evidence on file: the Home Office notice itself.

Ground 8 — Serious rent arrears (mandatory, 4 weeks)

Two or more months' rent unpaid both at the date of notice and at the date of hearing. The threshold was raised under the RRA from two months to three months for some tenancy types — confirm the applicable threshold for the specific tenancy before relying on it.

Evidence on file: rent ledger going back at least the full arrears period, payment record showing missed and partial payments, evidence of attempts to engage the tenant on the arrears.

Operational trap: Ground 8 fails if the tenant pays down to below the threshold before the hearing date. Many tenants do exactly this. Always serve Ground 10 (some arrears, discretionary) and Ground 11 (persistent late payment, discretionary) in the alternative.

Ground 8A — Persistent rent arrears (mandatory, 4 weeks) — NEW

The tenant has been at least two months in arrears on three or more occasions within the previous three years. This is the answer to the "pay down before the hearing" pattern that defeats Ground 8.

Evidence on file: rent ledger going back three years, with the three qualifying occasions clearly identified by date and arrears amount.

Ground 9 — Suitable alternative accommodation (discretionary, 2 months)

The landlord has offered or arranged suitable alternative accommodation for the tenant.

Ground 10 — Some rent arrears (discretionary, 2 weeks)

Any rent unpaid at the date of notice. Almost always served alongside Ground 8 as a fallback.

Ground 11 — Persistent late payment (discretionary, 2 weeks)

The tenant has persistently delayed paying rent, even where they are not currently in arrears.

Evidence on file: rent ledger showing the pattern of late payments, rent reminder correspondence.

Ground 12 — Breach of tenancy (discretionary, 2 weeks)

The tenant has breached an obligation in the tenancy agreement other than the obligation to pay rent.

Evidence on file: the tenancy agreement, evidence of the breach, correspondence asking the tenant to remedy it.

Ground 13 — Deterioration of property (discretionary, 2 weeks)

The condition of the property has deteriorated due to the tenant's conduct.

Evidence on file: check-in inventory, dated photographs of current condition, contractor quotes, correspondence.

Ground 14 — Anti-social behaviour, discretionary (discretionary, can be immediate)

Tenant or someone living with or visiting them is causing nuisance, annoyance, or has used the property for illegal purposes.

Evidence on file: logged complaints with dates, neighbour statements, police incident numbers, correspondence with the tenant.

Ground 14ZA — Riot conviction (discretionary, 2 weeks)

The tenant or a person residing with them has been convicted of an offence committed during a riot.

Ground 15 — Deterioration of furniture (discretionary, 2 weeks)

Furniture provided under the tenancy has deteriorated due to ill-treatment.

Ground 16 — Employee tenancy (discretionary, 2 months)

The tenancy was granted because the tenant was an employee of the landlord, and the employment has ended.

Ground 17 — False statement (discretionary, 2 weeks)

The tenancy was granted in reliance on a false statement made knowingly or recklessly by the tenant.

Evidence on file: the application form, referencing report, evidence the statement was false.

Ground 18 — Supported housing transitions (discretionary, 2 weeks)

Specific grounds for supported housing arrangements where care or support has ended. Operational relevance is narrow for most letting agents.

The notice periods at a glance

The single most common drafting error in May 2026 is matching the wrong notice period to the ground. Confirm the period from the statute or a current solicitor's note before each notice — do not reuse old templates.

What every Section 8 notice needs on file before service

Regardless of ground, a Section 8 notice will fail at the first hearing if any of the following are missing:

1. 1PRS Database registration current as at the date of service. Without it, the notice is invalid.
2. 2Current gas safety certificate. Held by the office, served on the tenant at the relevant points.
3. 3Current EICR. Same.
4. 4Current EPC at band E or above. See EPC requirements for rental properties.
5. 5Deposit protected within 30 days of receipt and prescribed information served. See tenancy deposit protection deadlines and prescribed information. Failure here remains a defence to most possession grounds.
6. 6How to Rent guide served at the start of the tenancy. Failure here was a defence to Section 21 historically, and it remains relevant evidence in discretionary Section 8 hearings.
7. 7The tenancy agreement itself. Signed, with all amendments and variations.
8. 8The rent ledger (for arrears grounds). Going back the full qualifying period.

This is the audit trail the court will check. The agent's job is not to draft the notice — that is solicitor work in any contested case. The agent's job is to make sure that on the day the solicitor asks for the file, every document is current, dated, and findable in under five minutes.

The operational traps showing up in week one

1. Re-using Section 21 mental models

Agents who served Section 21 notices on the calendar — six months in, two months notice, court if needed — are reaching for Section 8 the same way and finding the grounds do not fit. Section 8 is not a timeline. It is an evidence test. Restructure the office's possession workflow around evidence collection, not date triggers.

2. Forgetting the database registration

The PRS Database registration is the single most common reason a notice fails in court at first instance. The property's compliance documents may all be current, but if the database registration was not done, the notice is invalid. Run the database check before drafting every notice.

3. Missing the four-month protected period on Grounds 1A and 1B

Both new mandatory grounds carry a four-month protected period from the start of the tenancy during which they cannot be used. A notice served on a tenancy in its first three months will be invalid. Diary the four-month date on every new tenancy.

4. Not flagging the twelve-month re-letting restriction

Every property recovered on Ground 1A or 1B has to come off the marketing list for twelve months. If the system does not flag it, it will go back on the market in month six and the council will issue a £40,000 penalty. Flag the property the day possession is recovered.

5. Ground 8 alone, without alternatives

A tenant pays down £1 below the two-month threshold the day before the hearing, and Ground 8 collapses. Always serve Ground 10 and Ground 11 in the alternative. For repeat offenders, serve Ground 8A — that is what it exists for.

6. Missing rent ledger detail for Ground 8A

Ground 8A requires three qualifying occasions of two-month arrears within three years. The ledger has to clearly identify the three. A ledger of "monthly arrears running balance" without dated entries showing the threshold being crossed three separate times will not satisfy the court. Keep ledgers in event-dated form.

7. Anti-social behaviour grounds without contemporaneous evidence

Ground 14 is discretionary. The judge will weigh the tenant's account against the agent's. A retrospective summary written for the notice carries far less weight than a dated log of incidents kept since the first complaint, with neighbour names and police reference numbers. Start the log on the first complaint, not on the day the notice is being drafted.

How to track grounds-readiness across a portfolio

For a managed portfolio, the practical question is not "what does Ground 1A require" — it is "across our 80 properties, which are ready to serve which grounds today, and which have a documentation gap." The fields that matter:

• Database registration status — current, expired, never registered
• Compliance status — gas, EICR, EPC, deposit, prescribed information, How to Rent guide
• Tenancy age — for the four-month protected period on Grounds 1A and 1B
• Rent ledger health — current arrears, historic arrears occasions for Ground 8A
• Open issue log — anti-social behaviour incidents, breach correspondence

A spreadsheet handles this poorly because the data is in eight different places — the database portal, the certificate folder, the accounting system, the inbox. The fields go stale, nobody updates them, and the first time anyone runs the report is the day a landlord asks for possession. By then it is too late.

A purpose-built compliance platform like Proplio keeps the property file together: certificates with expiries and reminders, database registration reference, tenancy details, and the audit log all on one record. When a landlord asks "can we serve notice on this property", the answer is one screen, not two days of email triage. CSV import migrates an existing spreadsheet in 30 minutes. £29/month flat, unlimited properties.

Key takeaways

• Section 21 is gone. Every possession action in England now runs through Section 8.
• The grounds list expanded. Two new mandatory grounds for landlord occupation (1A) and sale (1B), and a new mandatory ground 8A for persistent rent arrears.
• Notice periods lengthened. Most mandatory grounds are now four months, not two.
• PRS Database registration gates Section 8. Without a current registration, the notice is invalid.
• Possession is a documentation discipline. The court checks the file, not the agent's word. Compliance records, deposit protection, prescribed information, and ground-specific evidence all have to be on file before service.
• Mandatory grounds beat discretionary grounds. Where both apply, serve both — but the mandatory ground does the work.
• Ground 1A and 1B carry a twelve-month re-letting restriction. Flag every recovered property in the system the day possession is granted.
• Track grounds-readiness across the portfolio, not case-by-case. The agent who knows which 80 properties are ready to serve which grounds today is the agent whose landlords stay on the books.
