Certificate of higher education with ou then a undergraduate course at another UK uni

I'm going to start a course with ou to get a certificate of higher education in computing and mathematics. I'm doing this to meet the entry requirements for a computer science, software engineering or economics undergraduate degree, would I be able to get a student loan for both?
I've read that sometimes you have to pay for the first year of a degree if you have completed a cert of higher education, I wouldn't be able to pay for a year of university, would this not apply because its a higher level course overall? Any help would be appreciated, also is there an email address to contact student finance England?
