mumblecrumble - you can ask for your income not to be considered, but that just means the student will only get the non-means-tested portion of the loan - used to be 75%, but \i believe it's now gone down to 70% (one of the confusing things about student finance is that they keep changing it - first, second and third year students are currently all on different arrangements)
There are circumstances where the student can ask for their parents' income not to be considered, but they are pretty strict:
(From the form for 2009/10)
Your parents cannot be found or it is not
reasonably practicable to get in touch with
them.
You are irreconcilably estranged (have no
contact with) from your parents and this will
not change.
At any point from the age of 16 to the start
of your course, you have not been under the
legal care of your parents; and, for three
months or more, you have been in the
custody or legal care of, or have been given
accommodation by, a local authority.
Both your parents have died.
You have applied for student finance before,
and the parent who was assessed for a
contribution has died.
Your parents are living outside the European
Union and the assessment of their financial
circumstances would place them in jeopardy.
Your parents are living outside the European
Union and it would not be reasonably
practicable or possible for them to send you
money.
If you have ticked any of the boxes above, you will be contacted for evidence and, subject to this, you may be considered independent.
