I've used my GP quite a lot since Covid struck, and accessibly has been vastly improved from pre-Covid days.Are you sure the GP is closed? I get the impression that many are open to those that need it, but the press are spreading the rumour that they're closed! I've no idea to what degree this is the case....
It's all about the timing of when you get it, I suppose.
Ths first problem used to be that their phone was often engaged, and if not there were massive queues. Then, while their system didn't allow bookings more than a month in advance, sometimes there were no slots available in that period - in which case your only option was to show up at the surgery and claim an emergency appointment, which I did once at the suggestion of a receptionist.
Now the phone is answered promptly, and a GP calls you back within an hour or so. Around half of my issues were dealt with on the phone - if I was there in person there would only be verbal communication anyway. Otherwise, while on the phone with the GP, I would be offered a face-to-face appointment the same day. Also, very simple requests and questions are now dealt with through "email" and SMS.
I can envisage people and situations where the new system has disadvantages, but it works well for me.
