When I went through this I called. They booked me in a week after my private scan for a final check and confirmation.
Epu’s are typically open Monday - Friday, at least where I am x
I got referred last Saturday and got an appointment through on the Monday. I’m sure you’ll hear Monday don’t worry. X
I know that my EPU is closed on the weekends, I’m unsure if yours would be the same? If she has sent the referral, it’s best to wait for them to call.. If you haven’t heard anything by Tuesday morning then maybe give them a call Tuesday afternoon or Wednesday morning x
