Although the film has been produced by Anglia Ruskin University the information it contains applies to any degree course in the UK.
In order to apply for student finance you will need to create an account with Student Finance England. The following link will take you to the correct website
Student Finance England also provide a useful calculator which can give you an approximate idea how much Maintenance Loan your son/daughter might be awarded.
