In addition to the very good advice advice from saxy_jag -
if I were you, I'd go to a local college and see about getting a GCSE English, as universities require this level for entry to their degree courses. Otherwise, you will have to show that you have the equivalent level of English.
Some alternative English exams are IELTS, TOEFL or IESOL.
You will also need a certificate of completed high school education, but you probably already have that.
You might need to do part-time study, as I believe that regulations say that you need to have lived here for three years not solely for the purpose of education in order to qualify for 'Home student' Uni fees.
You don't say if you come from a EU member state, in which case regulations may be different - you may qualify for entry to university as a 'local' student, but you WILL need a recognised qualification in English.
Go along to your local college and make an appointment with the careers advisor and ask about this and also about Access courses (this advice comes from a former College principal).
By the way, most universities have creche facilities for the children of staff/students.
Good luck!
