Sorry typed this very late last night and was concerned this info didn't seem to be widely known.
On the other thread I think I said that Scotland is about to introduce self referral, and I didn't have time to look at Rape Crisis Scotland to see if they have links.
In Northern Ireland there is the Rowan Centre (link on other thread) and this new helpline.
And in Wales there is a new gov. helpline for domestic and sexual violence support and it has contacts for SARCs gov.wales/live-fear-free/sexual-violence
I think info via social media might work, but was thinking that in fact to have cards with numbers on left in women's toilets (if you can find one) but in cinemas and bars, but also in hairdressers, and so on. Even now I am more awake trying to find the right number view the internet is time consuming, so although a bit retro, a card with the relevant number(s) for your area / region seems more direct.
Though appreciate for anyone who has just suffered male violence you might not be thinking of anything clearly. 
My worry is that I have a horrible feeling that many of these services will be facing cuts and service short fall. Some rape crisis centres have waiting lists for counselling of up to a year. 
(the other thread was about women who have been raped being told they should report - but obviusly no one can tell a woman that, and that is why feminist in the early days did think of the idea of SARCs)
