Unfortunately although it sounds like a positive move, it won't do much to reduce or address DV. Unless also:
a) More social housing, a supportive benefits system, improved support services.
b) Change the system so DV is treated like rape (obviously rape often happens within DV situations although not always).
By treat like rape, I mean it's the victim's choice whether or not to pursue criminal action against the abuser. If they don't feel able to cope with that, the priority should be on support (see point A) to keep them safe.
I know several women who've experienced DV. One returned to her husband because the only alternative was the substandard and unsafe temporary accomodation she'd been placed in.
And yes it was unsafe. Homeless people (which many DV victims become) are all lumped in together in often substandard "slumlord" housing, and because all lumped in together, DV victims are sometimes houses with people with substance issues and ex prisoners. Obviously those people also need help but it's inappropriate to house all together.
Another woman I know was given social housing. She's very grateful but terribly isolated and struggling when she so desperately needed to be housed near support. Several councils she applied for (including mine) gatekept. She wanted to be near me and other friends for support, which is totally understandable especially as her ex had isolated her from us.
