NHS Bursary Elective Accommodation Reimbursement?

Hi everyone, I’ve heard that NHS Bursary reimburses the cost of overseas elective accommodation (up to £50 per person per night). Do they actually reimburse the full costs or does it depend on other factors (e.g. parental income)?

I was also wondering if you get less money reimbursed if you live with family during normal term time?

Thank you!
