My advice would be to go for a degree that does give you BPS accreditation because it opens doors for you after you complete your degree, that way you wont be limited to only a few options like you would if you didnt get the accreditation.
There are a lot of other unis that offer a Bps accredited psychology with criminology. Here are a few suggestions, you might wanna look around a bit more though:
-Birmingham city uni
-University of west England
-Middlesex
-Southampton
-University of south wales
-Brighton
-Buckinghamshire New
