I feel like no-one's reading my posts 
Do the calculator on student finance. If the parents combined income is above the threshold (using your tax return for 2013-2014 for a student starting uni in September 2015) then there is no point in the parents creating their own account on student finance to support their DC. The DC will tick the relevant box to say they will not be assessed on parental income. They will then just get the student loan
If on the other hand the DC can get a grant as well as a loan due to parental income, then the parents create their own account in support of the DC.
DD was sent an excellent booklet from sheffield on this.
It appears that for DC starting this September, if parental income is less than £62143, then parents should support the loan. For a grant the top amount is £42,620.
The loan is repayable, the grant is not.
Yes it is a hassle. I had to send off all my bank statements, copies of tax returns etc. Then my income dropped by more than 15% for the current year so I had to repeat the process so DD could get more. However she is over £3,000 better off (or rather I am as it covers a large part of her accommodation)
