If I take a second Cert HE course, am I still eligible for tuition fee funding?

Hi there,
Just to give some context, I am currently a mature student studying an online distance learning Psychology BSc at Essex online university. At this moment I am in the CertHE stage, and I am considering changing my course to computer science.
I received student funding for my tuition fees, as well as a small amount of disability equipment allowance, as I am diagnosed ADHD.
My question is, if I decide to only complete the CertHE stage of my psychology BSc, would I then be able to start the computer science BSc and still get my tuition fees paid again?
I would really appreciate some advice on this, as I am currently communicating with the Essex online support team on the best steps forward for my studies.
Looking forward to hearing from you, thanks in advance.
Zak
