OP here are your options:
Contact the police. You can try to get to a Boots and ask for the 'consultation room' from there you can call the police. Dial 101 and tell them what is going on and they will advise. You can also report via the internet here.
Contact Women's Aid live chat, keep trying.
If he attacks you again or goes to attack you dial 999 and call the police. If they arrest him and take him away, you have time to pack and get to a refuge. They can keep him away from you for 48 hours. They also have a domestic abuse unit who can help you get away. If you need to get to the hospital, tell the staff about the abuse and ask for help. Write it down and hand them a note if you can't talk.
In the meantime, keep emailing the domestic abuse organisations (who can call around for you) as well as the refuges. If one of them gets back to you with a phone number, tell them you cannot make calls and ask for an email address.
If you can get to the doctor, your GP should be able to help you with a referral and by making calls. They will ask him to leave the room and they will help. They are in contact with local DV organisations.
There's also the Domestic Abuse Helpline which is 24 hours: 0808 2000 247
