Section 21 Abolished —
What Landlords Must Do Now

What Was Section 21 and Why Has It Gone?

Section 21 of the Housing Act 1988 allowed landlords to recover possession of a property without giving a reason — provided they gave the tenant at least two months' written notice after the initial fixed term had expired. It became the most widely used possession route in the private rented sector, partly because of its simplicity and partly because landlords could use it as a fallback whenever a tenancy became difficult to manage.

The Renters' Rights Act 2025 abolished it entirely. The government's stated reason was to give tenants greater security and prevent landlords from using the threat of a no-fault notice as a means of silencing legitimate complaints about property conditions or rent increases.

Whatever the political context, the legal reality for landlords is straightforward: from 1 May 2026, Section 21 does not exist. There is no equivalent replacement. Instead, all possession claims must be brought under Section 8 of the Housing Act 1988, using one of the specific statutory grounds.

What Has Replaced Section 21?

Section 8 of the Housing Act 1988 has existed alongside Section 21 for decades, but it was rarely the preferred route for landlords because it required specific grounds — and tenants could challenge the claim in court. With Section 21 gone, Section 8 is now the only mechanism available.

The Renters' Rights Act 2025 significantly overhauled the Section 8 grounds framework, adding new grounds and adjusting notice periods to make the route more practical for landlords acting in good faith. The most important grounds for most residential landlords are set out below.

The Key Section 8 Grounds — Plain English

What Compliance Must Be in Place Before Section 8

This is the critical point that many landlords miss. Under the old regime, a landlord with compliance gaps could often rely on Section 21 as a backstop because it did not require any court assessment of the tenancy history. Section 8 is different — courts assess the condition of your compliance record as part of the possession process.

In practice, the following must be in place and provably served before any Section 8 possession claim is likely to succeed:

How to Serve a Section 8 Notice — The Process

Serving a Section 8 notice is a formal legal process. The steps below cover the standard process for most residential landlords in England. Always verify current requirements against gov.uk guidance before serving, as forms and procedures can change.

1. Check all compliance is in order — use the checklist above. Any gap can be used to challenge the notice.
2. Identify the correct ground or grounds — you can rely on more than one ground in a single notice. Most notices for rent arrears use Grounds 8, 10, and 11 together.
3. Use the correct form — Section 8 notices must be served using Form 3. Ensure you are using the current version from gov.uk, not an outdated template.
4. Fill it in accurately — specify the grounds clearly, with dates and amounts where relevant. Errors in the notice give tenants grounds to challenge it.
5. Serve it correctly — hand delivery, first-class post, or email (if the tenant has agreed to email service in writing). Keep proof of service.
6. Wait for the notice period to expire — notice periods vary by ground. Do not apply to court before the notice period has run.
7. Apply for a possession order — if the tenant does not leave after the notice expires, apply to the county court. The tenant will receive the claim and can respond.
8. Attend the hearing — for discretionary grounds especially, you will need to present your case and evidence.

Important Restrictions on Section 8

Several restrictions apply to Section 8 grounds that did not exist under Section 21. These are not exhaustive, but the most significant for residential landlords are:

• Six-month restriction on Grounds 1 and 1A — you cannot use Ground 1 (moving in) or Ground 1A (selling) within the first six months of a tenancy. This prevents landlords from letting properties on a rolling basis and then recovering possession almost immediately.
• Re-letting restriction after Ground 1A — if you use Ground 1A to sell, you cannot re-let the property within 12 months. This prevents landlords from using the selling ground as a disguised mechanism for clearing tenants.
• No-DSS provisions — from 1 May 2026 landlords cannot refuse to rent to tenants receiving housing benefit or Universal Credit. A blanket 'no DSS' policy is a civil offence.
• PRS Ombudsman registration required — landlords must register with the Private Rented Sector Ombudsman. Failure to register will eventually prevent possession orders being granted (except for antisocial behaviour grounds). Registration is expected to open in late 2026.
• PRS Database registration — a new national database for landlords and properties is being introduced. Properties must be registered before being let. Failure to register will block possession claims (other than for antisocial behaviour).

Why Deposit Compliance Matters More Than Ever

Under the old Section 21 regime, a landlord could sometimes work around a deposit compliance error by returning the deposit in full before serving a notice. Section 8 is less forgiving. Under Section 8, the court considers the tenancy history as a whole — and a deposit protection failure, even if subsequently remedied, can be raised by a tenant as evidence that the landlord has not acted in accordance with their legal obligations.

More practically: deposit prescribed information failures remain independently actionable. A tenant can bring a claim against you for one to three times the deposit amount regardless of whether you are seeking possession. If you are in possession proceedings and the tenant brings a counterclaim for deposit penalty at the same time, the hearing becomes significantly more complex and expensive.

What to Do Now

Whether you are letting a property for the first time or managing an existing portfolio, the steps below set out the practical priority order:

1. Audit every tenancy for compliance gaps — use a systematic checklist covering gas, EICR, EPC, deposit protection, prescribed information, How to Rent guide, smoke alarms, and Right to Rent checks.
2. Fix any gaps immediately — do not wait for a dispute to arise. Address missing or expired documents now.
3. Serve the Renters' Rights Act Information Sheet — if you had existing tenants before 1 May 2026, this must have been served by 31 May 2026. If you missed this deadline, take legal advice on your position.
4. Update your tenancy documents — ensure any new tenancies created after 1 May 2026 include written terms covering rent, deposit, notice periods, landlord details, and key obligations.
5. Set up certificate renewal tracking — gas safety certificates must be renewed every 12 months, EICRs every 5 years. A lapsed certificate at the point you need to serve a possession notice can delay proceedings significantly.
6. Familiarise yourself with Section 8 grounds — understand which grounds apply to your situation before you need them. Taking legal advice before serving a notice rather than afterwards is significantly cheaper.

Frequently Asked Questions

Can I still evict a tenant who is not paying rent?

Yes. Ground 8 is a mandatory ground — meaning if you can prove the tenant owed at least three months' rent both at the time the notice was served and at the date of the hearing, the court must grant possession. The key requirements are that your compliance is in order and that the arrears threshold is met at both points in time.

What if a tenant refuses to leave after a Section 8 notice?

If the notice period expires and the tenant has not vacated, you apply to the county court for a possession order. The tenant receives notice of the claim and can respond. The court hearing is normally listed within weeks for mandatory grounds and longer for discretionary ones. You cannot physically remove a tenant yourself — you must obtain a court order and then, if necessary, instruct bailiffs to enforce it.

How long does Section 8 possession take?

Current timescales for straightforward mandatory ground claims (such as serious rent arrears) are typically 8–16 weeks from notice to possession. Contested or discretionary claims take longer. Courts have indicated timescales may increase as the volume of Section 8 claims rises following the abolition of Section 21.

Do I need a solicitor to serve a Section 8 notice?

You are not legally required to use a solicitor. However, given the stricter requirements and the consequences of a procedural error, taking legal advice before serving — particularly for anything other than a straightforward rent arrears case — is strongly recommended. A single error in the notice can cause the claim to fail, requiring you to start again.

Can I use multiple Section 8 grounds in one notice?

Yes. Most solicitors recommend including all applicable grounds in a single notice. Using Grounds 8, 10, and 11 together in a rent arrears case, for example, means the claim does not fail entirely if the arrears drop below three months between notice and hearing — Ground 11 can still apply.
