I've had a quick look and some uni's appear to use the codes for different courses. The main type of Psychology degrees are (someome correct me if I miss anything):
BSc Psychology - standard 3 year degree, should (check first) be BPS accredited and will confer GBC (graduate basis for chartership)
BSc Clinical/health/XXX Psychology - The standard Psychology degree with a focus on a particular area. As far as I am aware the differences are limited (often just one module) and should still be accredited and confer GBC
BSc Psychology and (Criminology, sociology, XXX) - These are joint honour courses which blend two subjects. Some of these are accredited by the BPS, some are not - you have to check.
BA Psychology (including health/clinical/XXX and the joint honours) - These are psychology courses with (generally) less emphasis on the statistics element. I'm not sure where they sit with regard to BPS accreditation. But, if you're pursuing a career in Psychology, I'd avoid a BA completely, it just generally looks less valuable than the BSc
MA/MSc Psychology - These are 4 year courses which incorporate the undergraduate and masters into one. Pretty useful as you'll likely get a funded masters, without competing for the slot as well. Again, avoid the arts one (unless you have a specific plan in mind).
4 year Psychology degree - These incorporate a placement year and are incredibly valuable. Knowing what I do now, I'd fight tooth and nail to get onto a sandwich course.
Essentially you'll be fine on any BSc/MSc Psychology course, provided it is accredited by the BPS.
