Section 8 notices in 2026: how to serve one correctly

Since 1 May 2026, a Section 8 notice has been the only way for a landlord in England to recover possession of a rented home, and from that date it must be served on the new prescribed Form 3A. The form, the preconditions and the notice periods all changed under the Renters’ Rights Act 2025, and a notice that gets any of them wrong is struck out, costing months. This guide explains the form to use, what must be in place before you serve, how to complete and serve the notice correctly, the notice periods, and what happens once the matter reaches court. For the wider picture of how eviction notices work now Section 21 has gone, see our eviction notices guide.

What a Section 8 notice is

A Section 8 notice takes its name from Section 8 of the Housing Act 1988 and is the written notice a landlord serves to begin recovering possession on one or more legal grounds. It replaced Section 21, the no-fault route that has now gone, so every possession claim must now name a specific Schedule 2 ground. Those grounds split into two types, and whether a ground is mandatory or discretionary changes how the claim runs: on a mandatory ground the court must order possession once the ground is proved, while on a discretionary ground it does so only if it also decides that is reasonable.

This guide covers the notice itself. The full grounds for possession, mandatory and discretionary, with the detail of each one, its threshold and its notice period, sits in its own guide. You can rely on more than one ground in a single notice, and where you do you must generally give the longest of the notice periods, with specific rules applying to the antisocial-behaviour grounds.

Form 3A: the prescribed form from 1 May 2026

The notice must be served on the prescribed Form 3A. From 1 May 2026, Form 3A replaced the old Form 3 for the private rented sector in England, and the government’s own form states that it is for private-sector use only, with social-sector landlords continuing to use Form 3. Serving a private-sector notice on the old Form 3, or on any home-made version, invalidates it, so download a current copy from the assured tenancy forms page on gov.uk every time rather than reusing a saved file.

In practice, across the self-managing landlords we work with, the wrong or outdated form is now one of the two most common reasons a notice fails. The form changed at commencement, and a notice prepared from a template saved in early 2026 may already be out of date.

What must be in place before you serve

Several preconditions must be satisfied or the court can refuse possession, so they are worth checking before the notice goes out rather than after.

If you are relying on Ground 8, the arrears recovery process around it is worth reading in full, and it helps to keep a clear, date-stamped record of every payment from the start of the tenancy, because the ledger is the evidence a court will want to see at both dates.

How to serve a Section 8 notice correctly

The notice is only the first step, and most failures happen here rather than in court. Work through the sequence below.

1. Choose the ground or grounds and the right notice period. Identify every ground that applies and the longest notice period among them.

2. Use the current Form 3A. Download a fresh copy from gov.uk for the private rented sector.

3. Complete it accurately. Include the full property address, the names of all tenants, every ground relied on with its full statutory wording rather than just a number, a short explanation of why each ground applies, and the date after which proceedings may begin. Errors here are the most common reason a notice is declared invalid.

4. Serve every joint tenant. Each joint tenant must be served individually; serving one is not enough.

5. Use a reliable method and keep proof. Serve in person, by first-class post, or by any method the tenancy agreement permits, allow posting time, and keep dated proof of service such as a certificate of service or a recorded-delivery receipt.

6. Note the notice’s shelf life. A Section 8 notice lapses if you do not begin possession proceedings within 12 months of serving it, and a notice cannot be amended once served. If you find an error, withdraw it and start again.

Notice periods at a glance

Notice periods changed under the Act, and miscounting the expiry date, which runs from the date of service rather than the date of writing, is the other most common cause of a wasted notice. The table below summarises the periods for the grounds a private landlord is most likely to use; the full grounds for possession guide carries the complete list.

What happens after you serve

Serving a valid notice starts the clock but does not end the tenancy. If the tenant has not left by the time the notice expires, you apply to the county court for possession, normally on Form N5 with the particulars on Form N119, attaching the tenancy agreement, the notice with proof of service, and the evidence for each ground. Where the claim rests only on arrears grounds, it can be issued through Possession Claims Online. The court cannot make an order at all unless the deposit was protected.

At the hearing, the judge decides whether the ground is proved and, on a discretionary ground, whether possession is reasonable. A successful claim produces a possession order, usually giving 14 days to leave, extendable to a maximum of six weeks where the tenant would suffer exceptional hardship. On a discretionary ground the order may be suspended on terms, for example that the tenancy continues while the tenant pays current rent plus a contribution to arrears. If the tenant still does not leave, you apply for a warrant of possession and county court bailiffs carry out the eviction. Recovering the property without a warrant, by changing the locks or otherwise, is illegal eviction and carries criminal and civil liability. From notice to enforcement the process now commonly takes several months, because the accelerated route that accompanied Section 21 no longer exists, and how long eviction takes in 2026 sets out the timeline in full.

Common mistakes that invalidate a Section 8 notice

The process is unforgiving of procedural error. The failures below account for most struck-out notices.

The penalties for getting it wrong

Misusing the possession process now carries real financial risk, on two levels. Procedural breaches, such as serving an old-style notice, attract a civil penalty of up to £7,000. Serious breaches attract a civil penalty of up to £40,000, with a starting point of £25,000 in the government’s statutory guidance, or prosecution. Two of those serious breaches matter most to a landlord serving Section 8.

First, where you obtain possession under Ground 1 (occupation) or Ground 1A (sale), a restricted period of 12 months runs from the date the tenant leaves, during which you, and any agent acting for you, must not re-let or market the property except to a qualifying family member. Breaching that restriction is an offence carrying the £40,000 maximum penalty. Second, relying on a ground without reasonably believing you can obtain possession, where the tenant then surrenders within four months without a court order, carries a civil penalty of up to £7,000, while knowingly or recklessly misusing a ground is a criminal offence. A tenant can also apply for a rent repayment order of up to two years’ rent. The practical lesson is to use Ground 1A only where a sale is genuinely intended, and to serve only on a ground you can actually prove.

Staying ready before you ever need to serve

The notices that succeed are the ones backed by records kept from the start of the tenancy, not assembled in a hurry once a problem appears. A complete rent ledger proves the Ground 8 threshold at both dates. Protected deposits, in-date safety certificates and a clear paper trail of correspondence keep the preconditions satisfied and strengthen any contested hearing. The landlords who fare best keep all of it in one place, so it helps to keep certificates, notices and correspondence in one place rather than across email, paper and memory, so that an evidence file can be produced as a single, dated record if a tenancy ever reaches that point.

Frequently asked questions

Which form replaces Form 3 for a Section 8 notice?

For the private rented sector in England, Form 3A replaced Form 3 from 1 May 2026. Social-sector landlords continue to use Form 3. Download the current Form 3A from the assured tenancy forms page on gov.uk for every notice.

Do I still have to protect the deposit before serving? 

Yes, for most grounds the deposit must be protected and the prescribed information served before the notice. Unlike under Section 21, you can do this late, provided both are completed before you serve.

How long does a Section 8 possession take? 

It varies by ground and by whether the case is contested, but from notice to enforcement it now commonly takes several months, because the accelerated route that went with Section 21 no longer exists.

Can I still serve a Section 21 notice? 

No. New Section 21 notices cannot be served on or after 1 May 2026, and attempting to end a tenancy that way carries a civil penalty. Section 8 is the only route. If you want to get your records in order before you ever need to serve, you can start for free.
