It is possible that you may be eligible for a higher level of funding, depending on your new circumstances.
You need to contact your funding body and ask for a current year assessment. You’ll be asked to provide evidence of the new household income (i.e. your parents/partners) and if household income has dropped by more than 15% then your funding body may be able to reassess your application. Read the Student finance England guide here for more information and to download the Current Year Income Assessment form.
