Kent
If you wish to self refer because you wish to address your abusive behaviour in relationships then there are contact details (attached) for Kent-based groups that can help you.
If you have been directed by Cafcass to attend a domestic abuse programme then ask Cafcass to refer you to the Building Better Relationship programme. They would be able to nominate you for assessment as Cafcass have a contract with the team who deliver the programme.
If you are currently on probation and feel the need to attend a programme to manage any levels of aggression in your relationship, you can speak to your probation officer. You could be added to the next programme at or near your probation office.
There is currently no cost for these programmes.
