Section 8 Notice: Complete Guide for UK Landlords (2026)

With Section 21 now abolished under the Renters'' Rights Act 2025, the Section 8 notice is the main way landlords in England regain possession of a property. Getting it right matters: a mistake in the ground, the notice period or the paperwork can see a court throw out your claim and send you back to square one.

What is a Section 8 notice?

A Section 8 notice is a formal notice served under Section 8 of the Housing Act 1988 (as amended). It tells the tenant you intend to seek possession using one or more legal grounds. Unlike the old Section 21 route, you must give a reason, and if the tenant does not leave you must prove that reason in court.

The main grounds for possession

Grounds are split into mandatory grounds, where the court must grant possession if proven, and discretionary grounds, where the court decides whether possession is reasonable.

Mandatory grounds landlords use most

• Ground 8 (rent arrears): at least three months'' rent unpaid both when the notice is served and at the court hearing. The arrears threshold increased from two months under the 2025 Act.
• Ground 1 (landlord moving in): you or a close family member genuinely intend to live in the property. You cannot have used the property as a rental in the period the rules restrict, and you cannot re-let it for a set period afterwards.
• Ground 1A (selling the property): you genuinely intend to sell. This ground cannot be used in the first 12 months of a tenancy, and re-letting restrictions apply afterwards.

Discretionary grounds

• Ground 10 and 11: some rent arrears or persistent late payment, even below the Ground 8 threshold.
• Ground 12: breach of a tenancy obligation other than rent.
• Ground 14: antisocial behaviour or nuisance. This ground has no notice period and can be acted on immediately.

Notice periods in 2026

Notice periods depend on the ground. Ground 8 now requires four months'' notice. Most other mandatory grounds require two months. Ground 14 for antisocial behaviour can be immediate. Always check the current prescribed form and period before serving, because using the wrong period invalidates the notice.

How to serve the notice

1. Use the current prescribed form (Form 3 or its successor).
2. State every ground you rely on, with full particulars. Vague particulars are the most common reason claims fail.
3. Serve it correctly: in person, by post to the property, or by email if the tenancy agreement allows it. Keep proof of service.
4. Wait for the notice period to expire before applying to court.

If the tenant does not leave

After the notice expires you apply to the county court for a possession order. For mandatory grounds with clear evidence, the hearing is usually straightforward. If the tenant still refuses to leave after a possession order, you need a warrant for bailiffs. The whole process typically takes several months, so serve notice promptly when a ground arises.

Common mistakes to avoid

• Citing Ground 8 when arrears are below the three-month threshold at the hearing date.
• Thin particulars: "rent arrears" is not enough, list the amounts and dates.
• Serving an out-of-date form.
• Harassing the tenant or changing locks, which is illegal eviction and a criminal offence.

What to do this week

• Check any current arrears against the three-month Ground 8 threshold.
• Download the current prescribed notice form from GOV.UK.
• Start a paper trail now: rent statements, letters and inspection notes win cases.
• Keep every notice, proof of postage and tenancy document in one place so you can produce them in court at short notice.
