Anti-social behaviour

Find out what anti-social behaviour is, and what you may be able to do about it.

ASB case review

The ASB case review, formerly known as the community trigger, enables anti-social behaviour victims to demand action and a case review when persistently reported problems have not been addressed.

How to activate the trigger

If you've reported 3 incidents of anti-social behaviour in the last 6 months, to the police, your housing agency or us, and you feel that no action has been taken, you can start a case review.

What happens next?

Once the ASB case review has been activated, we will meet with all relevant agencies to try to resolve the issue. We will:

  • Acknowledge your request for action within two working days
  • Ensure your case is reviewed by a panel of professional from multiple agencies within 12 working days, or nearest date available to ensure all relevant officers’ attendance
  • Invite you and any other victims to part of the panel meeting so that your voice is heard and your experiences understood
  • Inform you of the outcome and a proposed action plan (if applicable) within fifteen working days of the review

If you wish to appeal the panel’s decision, you must do so in writing within 10 working days of receiving the decision letter; outlining clearly the points that you are appealing.

Please send your appeal letter to:

ASB Case Review Appeals, 
Mark Chalmers, Head of Service,
Community Safety and Specialist Services, 
Public Protection and Licensing, 
Westminster City Council,
64 Victoria Street,

or by email: [email protected].

We promise to keep you updated with the investigation and any action we take.
