Ground 14 is the ground for antisocial behaviour. It is one of the most emotionally charged possession routes — landlords use it when there is real harm being done, either to neighbours or to the property — and it is the ground that landlords most often lose. Not because the behaviour isn’t real, but because it is a discretionary ground, and the court can refuse possession even where the facts are proven if the landlord cannot show the case is reasonable.
The Renters’ Rights Act 2025 kept Ground 14 largely intact but strengthened the mandatory ASB ground (Ground 7A) and made small procedural changes to Ground 14 — notably the ability to seek possession immediately (0-day notice period), which used to require just cause to be established at issue of proceedings.
This guide is about what actually wins a Ground 14 case in 2026: what counts as ASB in law, what the "reasonable" test really means, what evidence courts want, when Ground 7A (mandatory) is the better choice, and how to build the case from day one instead of scrambling three months in.
Not legal advice. ASB cases are fact-heavy and contested. If serious ASB is happening at your property, instruct a housing solicitor early — early enough that they can shape the evidence-gathering, not just present what you already have.
Ground 14 in the Act
Ground 14 sits in Schedule 2 of the Housing Act 1988 (as amended by the RRA 2025). It applies where:
> The tenant or a person residing in or visiting the dwelling-house has been guilty of conduct causing or capable of causing a nuisance or annoyance to a person residing, visiting or otherwise engaging in a lawful activity in the locality; or has been convicted of using or allowing the dwelling-house to be used for immoral or illegal purposes, or an arrestable offence committed in, or in the locality of, the dwelling-house.
(Note: pre-RRA 2025 the wording was "likely to cause". The RRA 2025 amended it to the lower-threshold "capable of causing" — a broader test that landlords should be aware helps their case.)
Four elements to notice:
Ground 14 is discretionary: even if all four elements are proven, the court may refuse possession if it is not reasonable. That is where the case is usually won or lost.
The "reasonableness" test — what the court actually weighs
Section 7(4) of the Housing Act 1988 requires the court, before granting possession on a discretionary ground, to be satisfied that it is reasonable to do so. The court weighs:
In favour of possession
Against possession
Courts genuinely balance these. A tenant with young children and evidence of a recent mental-health crisis, facing a possession claim built on incidents from six months ago that have since stopped, will often keep possession even though the facts are technically proven.
When Ground 7A (mandatory) is the better choice
The RRA 2025 retained Ground 7A — the mandatory ground for anti-social behaviour, introduced by the Anti-social Behaviour, Crime and Policing Act 2014. Where Ground 7A applies, the court must grant possession if the facts are proven; no reasonableness discretion.
Ground 7A applies where one or more of five specific conditions is met:
If any of the Ground 7A conditions is met, cite Ground 7A first on Form 3A. It is much stronger than Ground 14 and does not depend on the court’s view of reasonableness. If you are unsure whether the conditions are met, cite both Ground 7A and Ground 14 in the same notice — that is the standard practitioner approach and gives the strongest claim.
Notice period
Under the RRA 2025, Ground 14 has a notice period of 0 days — you can start proceedings immediately after serving the notice. This is a deliberate policy choice to allow landlords to act quickly on ASB.
But: 0 days does not mean 0 preparation. The court will still require evidence at hearing. Starting proceedings the day after service is fine tactically; getting to hearing without a diary of incidents, witness statements and (ideally) police-incident numbers is not.
Ground 7A also has 0-day notice under the RRA. Grounds that are 0-day are the "urgent" grounds — designed to prioritise resident safety over notice length.
What evidence wins Ground 14
The evidence question is where most Ground 14 cases are decided. Judges want to see:
1. A contemporaneous log of incidents.
Every incident: date, time, location, description, witnesses, action taken. Kept as a running diary from the first incident, not reconstructed the week before hearing. Contemporaneous logs are much more credible than after-the-fact statements.
2. Written statements from other residents.
Neighbours affected by the ASB should provide signed statements describing what they experienced. If they are willing to attend hearing to give evidence, all the better — hostility from other tenants that leads to lettings problems is weighty evidence of impact.
3. Police incident reports and CAD numbers.
Every 999/101 call about the tenancy should be logged with the police reference. Police records are hard for the tenant to deny.
4. Community Protection Notices (CPNs) and their history.
If the council has served CPNs on the tenant, breach or repeat is powerful evidence and may trigger Ground 7A.
5. Written warnings you sent to the tenant.
"We are aware of complaints from your neighbour on [date]. Please note that continued behaviour of this kind may result in possession action under Section 8 of the Housing Act 1988." Formal warnings show the tenant had notice and the opportunity to change. They also demonstrate that possession is proportionate.
6. Records of mediation offered or attempted.
Even if declined, offering mediation strengthens reasonableness.
7. Photographs and videos where lawful and relevant (damage, waste, evidence of prohibited use).
8. The tenancy agreement — showing the ASB clause and the tenant’s signed agreement to it.
What the RRA 2025 changed
The Renters’ Rights Act 2025 made several changes affecting ASB cases:
Ground 14 — no substantive change to the wording of the ground itself, but the notice period was harmonised at 0 days across the ASB grounds.
Ground 7A — expanded slightly. Condition 5 (breach of CPN/noise abatement notice) was clarified so that a single breach is now sufficient (previously the drafting was ambiguous).
New Ground 14ZA — serious offences during a riot. Ground 14ZA is a new discretionary ground added by the RRA 2025. It applies where the tenant, or an adult residing at the property, has been convicted in the Crown Court of a serious offence during a riot in the UK (as defined by section 1 of the Public Order Act 1986). It is discretionary — the court must be satisfied it is reasonable to grant possession — and requires a Crown Court conviction (Magistrates’ Court cases don’t qualify). It sits alongside Ground 7A (the pre-existing mandatory ASB ground) and Ground 14 (the general discretionary ASB ground) rather than replacing either. Ground 14ZA is targeted at post-riot disorder — a narrow but symbolically important addition, not a general repeat-ASB provision.
Ground 14 amended wording. The RRA 2025 also broadened Ground 14’s threshold from conduct "likely to cause" nuisance to conduct "capable of causing" nuisance — a lower bar for landlords. The evidence framework doesn’t change but the initial threshold is easier to cross.
Prohibition on retaliatory rent increases. Where a tenant has been the subject of an ASB complaint that has been raised in good faith, the RRA prohibits the landlord from responding with a Section 13 rent increase for 6 months. This does not affect Ground 14 procedure but is worth knowing if you were planning a rent review alongside possession.
Building the case from day one
If ASB is happening, the difference between winning and losing usually comes down to how much of the evidence was captured at the time versus reconstructed later.
If you are LetCompliance customer, the tenant issues log doubles as an ASB incident log. Every complaint, every message and every landlord action is time-stamped and exportable as a court-ready bundle. That is what wins Ground 14 in 2026 — a contemporaneous chain of evidence, not a rushed statement two weeks before hearing.

Frequently asked questions
Is Ground 14 mandatory or discretionary?
Discretionary. Even if the ASB is proven the court may refuse possession if it is not reasonable to grant it. Reasonableness weighs seriousness, duration, impact on neighbours, the tenant’s personal circumstances, and whether alternative remedies were tried. For mandatory ASB, use Ground 7A where its conditions are met.
What notice period applies to Ground 14?
0 days. The Renters’ Rights Act 2025 harmonised the ASB grounds at 0 days’ notice, meaning proceedings can be started immediately after service of Form 3A. Ground 7A also has 0-day notice. Cases still take months to reach hearing — 0-day notice is about starting the clock, not fast possession.
What evidence do I need for Ground 14?
A contemporaneous incident log, written statements from affected neighbours (ideally attending hearing), police incident numbers (CADs), any Community Protection Notices served, records of warnings and mediation offers, and photographs/videos where lawful. Reconstruction after the event is much weaker than a running diary — start logging the day the first complaint arrives.
What did Ground 14ZA add?
Ground 14ZA is a new discretionary ground added by the RRA 2025. It applies where the tenant or an adult residing at the property has been convicted in the Crown Court of a serious offence during a riot in the UK (defined by section 1 of the Public Order Act 1986). It is discretionary, not mandatory — the court must be satisfied it is reasonable to grant possession — and Magistrates’ Court cases don’t qualify. Ground 14ZA is narrow, targeted at post-riot disorder; it is not a general repeat-ASB provision. The RRA 2025 also broadened Ground 14’s threshold from conduct "likely to cause" to "capable of causing" nuisance.
