NHS has an updated list of where to find help (including how to cover your tracks online). Just as important is Respect Phoneline (for abusers who wish to change).
Dogs Trust Freedom Project and Refuge 4 Pets can offer fostering (usually in a different area) for people escaping abuse until they get settled (including tips on legal guardianship).
Anicare Handbook (also for children who have perpetrated or witnessed animal abuse) was created to help probation officers prevent future animal abuse). This also helps to prevent crime (nearly all serial killers have a history of animal abuse).
Luna Little Legs is a simple illustrated book to help children recover from trauma, if they have witnessed or experienced domestic abuse. With engaging text, it covers the abusers getting help or families moving to a refuge and then into their own homes. The age-appropriate language helps children from abusive families or situations talk about their feelings to other family members or professionals. Professionals can buy it with the supporting guidebook.
