I've not, but I didn't have any booked!
I know that routine antenatal appointments at local hospitals have been cancelled until further notice. I haven't heard news from the hospital on walk in centres and A&E admissions, but the advice from all the general and consultant clinics held there is to call ahead - presumably because no-one knows until the day whether they'll have the staff in.
I'm with the met office who say if it isn't urgent, reschedule rather than travel and if you must go - call ahead to avoid a wasted trip (I've seen numerous comments from people who've struggled in only to find their appt cancelled).
The trains here are running and a few buses are running a reduced service (the bus company have been using facebook to keep everyone up to date - outstanding effort). The cab firms are taking the brunt of it, I've heard it's hard to get a cab. One friend got out in her wheelchair yesterday but had to use the roads (good job her OH is a weightlifter). The little old lady on the corner went to the shops with her walking frame (took her more than two hours). The best way of getting round near here seems to be quad bike or horse - they're out in force.
