Anti-social behaviour by contract-holders can seriously affect neighbours and the wider community. Under the Renting Homes (Wales) Act 2016, landlords have specific grounds to seek possession when contract-holders engage in ASB. This guide explains how to use these grounds effectively.

Anti-Social Behaviour Eviction Wales
ASB can be grounds for possession but requires proper evidence

Anti-Social Behaviour Overview

Anti-social behaviour in the context of rental properties includes conduct that causes or is likely to cause nuisance or annoyance. This can include:

  • Excessive noise (loud music, parties, shouting)
  • Verbal abuse or harassment of neighbours
  • Violence or threats of violence
  • Drug dealing or use on the premises
  • Criminal activity at or near the property
  • Damage to neighbouring properties
  • Allowing visitors who cause problems
  • Accumulation of rubbish causing health hazards

Important Note

Contract-holders are responsible for the behaviour of anyone at the property, including visitors, children, and other household members. ASB by these individuals can be grounds for possession against the contract-holder.

ASB Possession Grounds

Under the Renting Homes (Wales) Act 2016, there are specific grounds relating to anti-social behaviour:

Ground 12: Estate Management Grounds (includes ASB)

This ground covers behaviour that causes nuisance or annoyance to people in the locality of the dwelling. The court must be satisfied that:

  • The contract-holder or person residing at or visiting the property
  • Has been guilty of conduct causing or likely to cause
  • Nuisance or annoyance to a person residing, visiting, or engaged in lawful activity in the locality

Ground 13: Serious Rent Arrears

While primarily about rent, serious arrears cases often accompany ASB issues and can strengthen your overall case.

Ground 14: Breach of Contract Terms

If your occupation contract contains terms about behaviour (which it should), ASB may constitute a breach giving rise to this ground.

Evidence Requirements

Strong evidence is essential for ASB possession cases. The court will need to be satisfied of the behaviour before making a possession order.

Types of Evidence

Evidence TypeExamplesStrength
Witness statementsNeighbours, other residents, visitorsStrong (if willing to attend court)
Diary logsDetailed contemporaneous recordsStrong (if detailed and consistent)
Photos/videosDamage, rubbish, incidentsStrong (if clearly dated)
Police reportsCrime reference numbers, incident reportsVery strong
Council recordsNoise complaints, ASB team involvementStrong
Professional witnessesManaging agents, contractorsVery strong

Building Your Evidence Pack

  • Keep detailed records of all incidents
  • Include dates, times, and duration
  • Record who was affected and how
  • Note any warnings given to the contract-holder
  • Keep copies of all correspondence
  • Encourage affected neighbours to keep diaries

Witness Reluctance

Many neighbours are reluctant to give evidence due to fear of reprisal. Consider professional witness services or ask if they would provide statements anonymously (though this carries less weight).

Notice Requirements

Before seeking possession, you must serve the correct notice. For ASB grounds, you can use:

Standard Notice (Section 173)

  • Minimum notice period: 1 month
  • Can be served during any periodic standard contract
  • Must specify the ground(s) being relied upon

Landlord's Break Notice (Section 186)

  • For fixed-term contracts with break clause
  • Must comply with any notice period in the contract
ASB Notice Requirements Wales
Correct notice must be served before court proceedings

Court Process

The court process for ASB possession follows these steps:

  1. Serve the appropriate notice
  2. Wait for notice period to expire
  3. Issue possession claim at county court
  4. Attend hearing with all evidence
  5. Court decides whether to grant possession

Court Considerations

For discretionary grounds (which most ASB grounds are), the court must consider:

  • Whether the ground is established on the evidence
  • Whether it is reasonable to make the order
  • The impact on the contract-holder and any children
  • Any disability or vulnerability considerations
  • Whether the behaviour has stopped or is likely to resume

Order Types

The court may grant an outright possession order, a suspended possession order (with conditions), or adjourn the case. Even if ASB has stopped, historical evidence may still support an order.

Serious ASB Cases

In cases of serious anti-social behaviour, there are additional options and expedited processes available.

What Constitutes Serious ASB?

  • Violence or threats of violence
  • Drug dealing on the premises
  • Serious criminal activity
  • Harassment of neighbours
  • Behaviour causing significant distress

Expedited Possession

In serious cases, you may be able to:

  • Apply for an accelerated hearing
  • Request interim possession in extreme cases
  • Work with police for closure orders
  • Seek injunctions alongside possession

Working with Authorities

For serious ASB, coordinate with:

  • Police: Report crimes and request regular patrols
  • Council ASB team: They can take action and provide evidence
  • Environmental health: For noise and health hazards
  • Housing enforcement: May support your case
Serious ASB Cases Wales
Serious ASB cases may involve multiple agencies

Safety First

In cases involving violence or serious criminality, do not put yourself at risk. Work through solicitors and avoid direct confrontation. Consider seeking a non-molestation order if threats are made.

ASB FAQ

Can I evict for a single incident of ASB?

Generally, courts expect to see a pattern of behaviour. However, a single very serious incident (such as violence) could be sufficient. The more serious the incident, the less pattern is needed.

What if my contract-holder denies the behaviour?

This is common. Strong documentary evidence and independent witnesses are crucial. The court will weigh the evidence from both sides. Professional evidence (police, council) carries significant weight.

Can I include ASB clauses in the occupation contract?

Yes, your written statement can include terms about behaviour. Breach of these terms can itself be a ground for possession, alongside the specific ASB ground.

What if neighbours won't provide evidence?

This is a significant challenge. Try to gather other evidence - CCTV, professional witnesses, police reports. Council ASB teams can sometimes provide evidence without naming individual complainants.

Should I try mediation first?

Courts look favourably on landlords who have tried to resolve issues before eviction. For low-level ASB, a warning letter and mediation attempt strengthens your case if court becomes necessary.
