[Date]
Dear [Tenant name(s)],
Re: [Property address] — Formal Warning Regarding Anti-Social Behaviour
I am writing to you formally regarding behaviour at the above property that has been reported to me and which constitutes anti-social behaviour (ASB) in breach of your tenancy agreement.
Incidents Reported
The following incidents have been reported or observed:
- [Date] — [Description of incident, e.g., loud music after 11pm causing disturbance to neighbours]
- [Date] — [Description of incident]
- [Date] — [Description of incident]
Your Tenancy Agreement Obligations
Your tenancy agreement requires you to:
- Not cause nuisance, annoyance or disturbance to neighbours or other residents
- Not engage in or allow behaviour that is likely to cause harassment, alarm or distress
- Ensure that members of your household and visitors comply with these obligations
What We Require From You
With immediate effect, you must:
- [Specific required action, e.g., Ensure music and noise is kept to a reasonable level at all times, and below audible levels outside your property after 10pm]
- [Specific required action]
- [Specific required action]
Consequences of Continued Behaviour
This letter constitutes a formal warning. If the behaviour described above continues or further incidents of anti-social behaviour occur, I will have no alternative but to take the following action:
- Serve a Section 8 Notice seeking possession of the property on the grounds of breach of tenancy agreement (Ground 12) and/or nuisance (Ground 14)
- Report the matter to the local authority ASB team
- Apply to the court for an injunction under the Anti-social Behaviour, Crime and Policing Act 2014
I hope that this formal warning will be sufficient to resolve the situation. I am willing to discuss this matter with you — please contact me on [phone/email] if you wish to do so.
Please confirm receipt of this letter by signing and returning the enclosed copy, or by email to [email address].
Yours sincerely,
[Landlord/Agent name]

Legal Note: Keep a copy of this letter and proof of delivery (recorded post or email read receipt). If you later serve a Section 8 notice on Ground 14 (nuisance), evidence of prior warnings strengthens your case. Under the Anti-social Behaviour, Crime and Policing Act 2014, landlords in the social sector have additional obligations to respond to ASB — private landlords should be aware of these standards as best practice.
