Alexander re rent it depends on area. One of my DC is renting an ensuite bedroom with use of kitchen but no meals for £135 a week (Oxfordshire). That would rent a whole house at home.
Uni costs - the experience of friends and colleagues is that Cambridge is cheaper than most unis and much cheaper than London or even Bristol. The college rent is reasonable and the fees the same.
The students don’t start to repay student loans until they earn over £25000. Then they pay 10% of their earnings above £25000.
Here are some amounts for annual repayments from moneysavingexpert.com:
If you earn £26,000 in a year, what do you repay?
The answer is £90, as £26,000 is £1,000 above the threshold and 9% of £1,000 is £90.
And if you earn £35,000, what do you repay?
The answer is £900. £35,000 is £10,000 above the threshold and 9% of that is £900.
