Because the GPhC is very strict on curriculum requirements, you wouldn’t have covered everything you need to on year 1 of a pharmacology degree. I don’t think any university will let you transfer into year 2.
I work at Bangor University and there you can complete year 1 of a pharmacology degree and then transfer to pharmacy, but it is subject to certain requirements.
The Uni of Hertfordshire also allows it, but it’s quite strict on requirements.
It varies very much on individual Unis so just email them but be aware it’s a really busy time at the moment so that might be why they’re not answering you
