Here is the information on becoming an audiologist:

https://careerpilot.org.uk/job-sectors/medical/job-profile/audiologistI am not sure whether you want to go in via NHS Practitioner Training Programme (PTP) or via the NHS Scientist Training Programme. The PTP is right after your A Levels (where you then specialise in audiology) and the STP is after your degree.
If you are looking for the degree apprenticeship (the PTP), then you would be coming across the following page for list of approved degrees for the PTP:

If you do an Access course, it would need to be in science (or something very closely related to science i.e. there should be at least 15 credits in one type of science). If the Access course isn't science heavy, then it's not likely that you would get in.
If you choose to drop chemistry, you're fine with just biiology. However, you would still need the equivalent of 3 A Levels to get into most degree apprenticeship courses (some will accept 2 A Levels, but why sell yourself short?).
If you choose to do the degree route (which is longer since you're doing 3 years for a degree on top before doing 3 years training), there is normally a plethora of degrees that they accept. However, according to the NHS website, the commonly accepted degrees include: physiology, pure or applied physics, engineering, biology or human biology, sports science (if there is significant scientific content). The Prospects webpage suggest something similiar: biology (or human biology), engineering, physiology, pure or applied physics, sports science (if the course has a significant amount of scientific content). In other words, you can do a random science degree in something related to physics or biology and still get in.
To my knowledge, most of these university subjects don't accept BTECs in Health and Social Care. You should be fine for a number of universities and biology related courses if you do Access in a science subject (again with at least 15 credits in biology) or a BTEC in Applied Science + A Level Biology + something else. However, you will struggle to get into engineering courses and physics courses with an Access course or without A Levels in Maths and Physics.
I don't know why they suggest you do a BTEC in Health and Social Care. Having said that, I don't work in uni admissions for any of these departments, so it pays for you to email them to check.
