Section 8 Notice Period Calculator

This section 8 notice period calculator gives landlords and tenants in England the earliest date a landlord can apply to court for possession under the rules in force since 1 May 2026, when section 21 ended and section 8 became the only route. Tick the grounds on the Form 3A notice, enter the date it was received and it applies the longest notice period, the 12 month protection for Grounds 1 and 1A and the Ground 8 arrears test. Figures checked October 2026.

Quick answer: The section 8 notice period is 4 weeks for rent arrears (Grounds 8, 10 and 11), 2 weeks for breach or damage, 2 months for grounds such as death of a tenant, and 4 months for moving in, selling or redevelopment. When a notice uses several grounds, the longest period sets the earliest court date.

What Is a Section 8 Notice Period?

A section 8 notice period is the minimum time a landlord must allow between giving a tenant notice seeking possession and starting court proceedings, and it depends on the ground used. The notice itself does not end the tenancy: only a court order does, and the tenant can stay until then.

The formula in plain words: earliest court date = the date the tenant receives the notice + the longest notice period among the grounds you rely on. For Grounds 1 and 1A, the date also cannot fall within the first 12 months of the tenancy. Court proceedings must then begin within 12 months of the date the notice was served, or the notice can no longer be used.

How to Use the Section 8 Notice Period Calculator

Step 1: Enter the Service and Tenancy Dates

Enter the date the tenant actually receives the notice and the date the tenancy began. If you are posting the notice, add extra days so the period still runs in full even if delivery is slow, following any service clause in your tenancy agreement.

Step 2: Tick Every Ground in the Notice

Select each ground you list in your Form 3A notice. The list covers the grounds private landlords use, with the notice period shown next to each. Social landlord only grounds such as 1B, 6A and 14A are left out.

Step 3: Check the Ground 8 Arrears Test

If you tick Ground 8, enter the rent and the arrears. The ground is only met when at least 3 months' rent is owed for monthly tenancies, or 13 weeks' rent for weekly or fortnightly ones, both when the notice is served and at the hearing.

Step 4: Read the Dates

The headline is the earliest date to apply to court. The stats show which period applies, the number of days from service and the latest date to start proceedings. The table lists each ground's own date, and the box explains any rule that moved a date. Put a date no earlier than the headline in the notice.

What Is the Notice Period for a Section 8 Notice?

The notice period for a section 8 notice ranges from none to 4 months, set ground by ground in section 8 of the Housing Act 1988 as amended by the Renters' Rights Act 2025. The full list in the current text of section 8 groups the grounds into four bands, which the table below summarises for private landlords.

Notice period	Grounds	Typical reason
4 months	1, 1A, 2, 2ZA to 2ZD, 4A, 6	Moving in, selling, lender repossession, student HMO, redevelopment
2 months	5, 5A, 5C, 7, 9	Employment related lets, death of a tenant, alternative accommodation
4 weeks	5E, 5F, 5G, 8, 10, 11, 18	Rent arrears and supported or temporary accommodation
2 weeks	4, 7B, 12, 13, 14ZA, 15, 17	Breach, damage, false statement, no right to rent
None	7A, 14	Antisocial behaviour (no order for 14 days)

How Long Is a Section 8 Notice for Rent Arrears?

A section 8 notice for rent arrears is 4 weeks, whether you use mandatory Ground 8 or discretionary Grounds 10 and 11. Before 1 May 2026 Ground 8 needed only two weeks and two months of arrears; it now needs four weeks and three months.

Worked example: Marcus lets a flat in Leicester at £1,200 a month and his tenant owes £3,750, just over three months' rent. He hands the tenant a Form 3A on Monday 5 October 2026 relying on Grounds 8, 10 and 11. All three need 4 weeks, so 28 days later, on Monday 2 November 2026, is the earliest date he can apply to court. The arrears pass the £3,600 threshold for Ground 8, but if the tenant pays them below that level before the hearing, only the discretionary grounds remain. He must start proceedings by 5 October 2027.

Can I Use Ground 1 or 1A in the First Year?

You can serve the notice during the first year, but it cannot take effect within the first 12 months of the tenancy. For a tenancy that began on 1 May 2026, a Ground 1A notice served on 5 October 2026 would allow court action from 5 February 2027 on the 4 month rule alone, but the 12 month protection pushes the earliest date to 1 May 2027. The GOV.UK grounds for possession guidance also explains the evidence each ground needs, so read it before you choose which grounds to rely on.

How Long Is a Section 8 Notice Valid?

A section 8 notice is valid for 12 months from the date it was served, so court proceedings must begin within that time. Notices for Grounds 7A and 14, which have no notice period, let you apply immediately, but the court cannot make a possession order until 14 days after notice was given. To count the exact gap between two dates, the days between dates calculator shows days and weeks, which helps when you are planning around a 4 month period.

Every section 8 notice period calculation here assumes the notice is valid in other ways: the correct Form 3A, with every ground and its explanation filled in. Before letting a new tenancy, the tenancy deposit cap calculator checks the deposit is within the 5 week limit, which avoids a dispute later. This tool covers England only, as Wales uses different notices.
