My surgery has started having better access hours for the late worker, I have copy/pasted under here what the website says.
"Improved Access (open for pre-booked appointments only)
We offer a range of pre-bookable doctor, practice nurse, HCA and appointments during Improved Access hours. Improved Access hours held at the surgery are most weekdays from 6.30pm to 8.00pm and some Saturday mornings."
Never been told about it but was searching for something on the Doctors website and noticed it in small print hidden on a page somewhere. So maybe check your GP's webpage and see if they do it.
My surgery is starting to look good in comparison lol!
Something I've heard about but not tried yet re online pre-bookable apmnt is that they sometimes release some extra apmnts just after 12 or 1am in the morning, so if your up till then it's worth checking.
