As others have said, incident helpline at British Cycling. 0161 274 2015, open from 9am on Monday.
Without knowing the exact specifics of the incident and without wishing to cast aspersions in any way…
You claim she’s responsible as she pulled out without looking.
Her insurance will probably try claiming that you’re responsible for “not leaving enough space in case someone stepped off the kerb/pulled out/did other daft move”
As I say, I’m not casting blame, simply saying that’s the argument which she and her insurance will try and pull. Just so you can prepare yourself for it.
In the meantime (assuming you’ve exchanged details), don’t get involved in any debate with her. No real point reporting it to the Police unless she was drunk/on the phone or she left the scene of the accident without stopping (which is obvious from your OP that she didn’t).
