Over recent decades tuition fees have been rising, but they've been covered by a special loan. Paying back this loan is taken out of your pay cheque (via PAYE) based on how much you earn. If you don't pay it back within a certain number of years it gets wiped.
Before the last major increase it was viewed by most of my peers (I graduated in 2013) as reasonable. Graduates could expect to pay it off.
Now graduates finish with £40,000-$50,000 and the interest rate is so high many won't ever pay it off.
Being able to support yourself during university might be a problem but there are bursaries and grants you can get.
Let me know if you want more details.
