Section 8 possession grounds explained in plain English

Since 1 May 2026, every eviction in England has to be justified. A landlord who wants a property back must name a ground from schedule 2 to the Housing Act 1988, serve a notice under section 8 that specifies it, wait out the notice period attached to that ground, and then persuade a court. This guide explains the grounds most tenancies actually turn on, how long each one takes, what mandatory and discretionary really mean in a courtroom, and the two 12-month restrictions that sit on the selling and moving-in grounds.

How a possession claim works now

There are three stages, and none of them can be skipped. First the landlord serves a notice specifying the ground or grounds relied on. Second, the notice period for that ground runs. Third, the landlord applies to the county court, and the court decides whether possession should be ordered.

The end of section 21 removed the option of doing all this without giving a reason - the background to that change is in section 21 abolition. What remains is a route that turns on evidence. A ground is not a label a landlord picks. It is something that has to be proved to a court on the facts.

Possession always needs a court order. A notice that has expired does not, by itself, entitle anyone to change the locks, and only a county court bailiff or a High Court enforcement officer can carry out an eviction. A landlord who removes a tenant any other way is not enforcing a ground, they are committing an unlawful eviction. The compliance checker sets out which duties attach to a given tenancy.

Mandatory and discretionary grounds

Mandatory grounds

If a mandatory ground is proved, the court must order possession. It has no discretion to weigh up the hardship the order will cause. Grounds 1, 1A and 8 are the mandatory grounds most often seen in the private rented sector. This does not make them automatic: the landlord still has to satisfy the court that the ground is genuinely made out, and a defective notice or thin evidence can sink a claim before the merits are reached.

Discretionary grounds

If a ground is discretionary, proving it is only half the job. The court must also be satisfied that it is reasonable to make an order. That opens the door to everything a judge might sensibly want to know - how long the tenant has lived there, whether the arrears are being cleared, whether there are children or health issues, whether the landlord contributed to the problem. Grounds 10, 11 and 14 are discretionary.

The grounds most tenancies turn on

These are the grounds that account for most private sector claims, but schedule 2 to the Housing Act 1988 contains others, covering situations such as employment-linked accommodation and mortgage repossession. The full list sits in the Act and the official government guide.

Grounds 1 and 1A: the two 12-month rules

The moving-in and selling grounds are the closest thing to a no-fault route that survives, which is why Parliament fenced them in from both sides.

The first fence is the protected period. A notice relying on either ground cannot name a date for starting court proceedings earlier than one year after the tenancy began, so the tenant gets that first year regardless of what the agreement says. The second fence sits at the other end: once a landlord relies on ground 1 or 1A, they cannot re-let the property, or market it to let, from the day the notice is served until 12 months after the notice period ends, whether or not the tenant actually leaves. That removes the obvious workaround of announcing a sale, emptying the property, and quietly re-letting it at a higher rent.

A worked example

Suppose a tenancy begins on 1 June 2026 and the landlord decides in the autumn that they want to sell. The notice has to give 4 months, and the date it names for starting court proceedings cannot be earlier than one year after the tenancy began. So the landlord could serve a section 8 notice relying on ground 1A on 1 February 2027, naming 1 June 2027 as the earliest date proceedings will begin. Court time sits on top of that, and the property cannot be re-let or marketed to let until 12 months after that date, so not before 1 June 2028. The protected year and the re-letting ban together make this a long-range decision - so a landlord who might want to sell needs to think about it when the tenancy starts, not when the estate agent calls.

The rent arrears grounds

Ground 8 is the mandatory arrears ground and the threshold is at least three months' arrears, or 13 weeks' where rent is paid weekly or fortnightly. Grounds 10 and 11 sit below it: ground 10 covers arrears of any amount, and ground 11 covers a pattern of paying late even where the account is square today. All three carry 4 weeks' notice, but only ground 8 obliges the court to order possession.

In practice this makes rent records the centre of any arrears claim. The ground turns on a figure, and a figure has to be evidenced with dated statements, receipts and correspondence rather than a recollection. It also makes early contact worth far more than it used to be: because grounds 10 and 11 are discretionary, how a landlord and a tenant behaved while the arrears were building is something the court can properly take into account.

Ground 14: antisocial behaviour

Ground 14 is one of two grounds where proceedings may begin immediately after the notice is served, without waiting out a notice period. The other is ground 7A, the mandatory ground for the most serious antisocial behaviour, such as a conviction for a serious offence or a closure order. The speed reflects the fact that the conduct ground 14 covers - nuisance, annoyance, or criminal behaviour connected with the property - can be urgent. It remains discretionary, which means the court hears the evidence and decides whether an order is reasonable. The speed is in getting to court, not in the outcome.

If you have received a section 8 notice

Read it before you react to it. Four things are worth checking straight away. Does it actually specify a ground? Does the notice period match that ground in the table above? Is the ground available at all - a ground 1 or 1A notice cannot name a date within the tenancy's first year? And is the factual basis correct, particularly where an arrears figure is quoted?

A notice is not an eviction and it is not a court order. It is the opening move. If the ground is discretionary you will be able to put your side of the story to a judge, and even on a mandatory ground the landlord has to prove the case. Your wider protections are set out in tenant rights under the Act, and the consequences for a landlord who gets the process wrong are in what happens if you get it wrong. If you would rather leave than argue, remember you can end the tenancy yourself with 2 months' written notice - the mechanics are in periodic tenancies explained.
