Buying a house alone, worried about about being able to afford it.

I've had an offer accepted on a house for £160k and my mortgage has been approved (25% ltv). I earn around £2k per month after tax and my monthly mortgage payments will be £520 before any bills, council tax etc. My mortgage advisor seems to think this will be affordable, though as i've never lived alone I'm struggling to work out how much I will be paying all in per month. It's a 2 bed terraced house with an EPC rating of C, so hoping bills won't be extortionate, however I'd love to get any opinions from those who have bought a house alone or those more clued up than me! Thanks in advance.
