180 on utilities seems very high to me - what's covered in that?
Nearly 150 on phones and broadband is also really high - as others have said, switch to PAYG, get basic internet.
If you really wanted to you could also probably get 160 on food down a bit, too - there might not be a lot of wiggle room but there's usually some to be found.
To keep treading water (which isn't really what you're doing but just for the sake of argument) you need to reduce your 1,200 of outgoings to 840, which means cutting 360 from what you spend somehow. If it seems overwhelming, try and think of it as ten chunks of thirty-six that you need to find somehow. (But, bear in mind that even if you had no mortgage or other debt, based on the figures you have given, you still wouldn't have enough money every month at your current income)
You'll be finished studying in four months so you have lots of decisions to make. Will you get a job immediately? Presumably not if you need to wait until the academic year begins again. Can you increase your hours at your part-time job? Can you get a second job (can you do that now without impacting too much on your studies)? If you have to move to the UK for work, what do you plan to do with your house/apartment? Will you rent it out? Can you rent it out for enough to cover the full mortgage? If so, why aren't you already doing that and living in a poky little boxroom in a house-share somewhere? If not, how do you expect to be able to pay the mortgage and upkeep as well as living costs in a different country?
