Getting married after submitting an application

I've already submitted my Student Finance application and applied for the lowest maintenance loan based on my parent's income.

However, my partner has recently proposed to me and we plan on getting married and moving in together before the next academic year begins.

This would alter my household income (due to living in a different household) and make me eligible for a higher maintenance loan I think.

How can I change this on my application after it has been submitted? I am aware that I can submit a change of circumstances form, but specifically I'd like to reapply to get the larger maintenance loan.

1) Am I correct that being married and living with my partner would restult in me getting a higher maintenance loan?
2) If so, how do I go about submitting this?
