Are my BTEC's valid if I fail GCSE English Language?

(Private Teacher Asking to support my student. Scenario explained by me but in first person to be clearer)

I have been accepted onto a BTEC course for ICT after failing my GCSE English Language. I'm doing really well in ICT and I expect to pass without any problems.

I find English Language very difficult as I have a language disorder. I am concerned I might fail again on my resit of English Language. If this does happen, will my BTEC be valid? Will I be able to get the qualification or does it depend entirely on me passing my English Language exam?

Also if anyone knows the answer, will universities accept my BTEC grades and admit me if I do not have a passing GCSE for English Language?
