Parents don't want me to move out for university

For now you have enough loan to cover accommodation with money to spare plus a job. Start saving as much as possible. This work should give you enough experience to get another job in the university area. If not it may be that you have to come home at weekends to work this existing job. Start researching the University area for possible sources of work when you get there. It will always be easier to get a job if you have had one before. Start working out a budget for your other costs so you know what you are working towards money wise. As regards your family not supporting you it sounds like they really are struggling financially but are perhaps too proud to tell you.
What are you planning on studying?

I'm planning on studying Computer Science with a year in industry so if I'm lucky enough I should get a work placement in my third year and hopefully a full-time job at the end of my degree.
Also, I do worry that my parents are struggling financially but this is only because they're financially recovering from house extensions - so much so that I have been phoneless for months because they refuse to spend money on me to get a reliable phone (which is why I found the job so I could buy one myself). They both work in the medical field and before this barely worried about money, when I was told they wouldn't support me it seemed more malicious than anything. Like, 'You didn't want to stay and went against what we wanted, we warned you and you didn't listen, so we won't help you when you need it'.
What can I do to create a rough estimate of my university expenses? (how can I calculate them), and would it be a good idea to slowly buy and build up university essentials from this point onwards?

Go to you tube and look for videos on student budgeting and tips for managing finances as a student. You can also get advice here on what to buy in your first year as a student.
Also consider degree apprenticeships in computer science.

One thing to bear in mind - if they refuse to “support” your SFE application next year then you would only be eligible for the minimum maintenance loan (SFE assumes that your household income is high if you don’t provide it).
So ideally you need to not only budget to get by this year but to build up savings to help cover even more costs next year. Looking for the cheapest accommodation, thinking about walking/cycling instead of taking the bus (unless your accommodation comes with a free bus pass) and getting experience in other types of work that might pay more (plus looking for full time holiday work early).
Generally accommodation, food and travel will be your biggest costs.
For other things charity shops and second hand will save you a lot of cash.

If my parents refused to support my SFE application next year, would I be able to apply as an estranged student to increase the amount of loan I receive?

Also, I forgot to add this to the original post but my parents will most likely refuse to pay the deposit for my accommodation so a large chunk of my paycheck will go towards that. Is it likely that cheaper accommodation will still be avaliable post results day? As that is roughly about the time I will have saved up enough to pay it.

Hi Anonymous,
Sorry to hear you are having some worries about finances at uni. I was in a similar position as I received the minimum student loan but no financial support from my parents. I am now in the second year of my undergraduate at Liverpool John Moores University and have been living away from home for both years. While I have had to be more savvy with my money than the average student, I have been able to get through university fairly comfortably. I have never gone without the necessities and have managed to maintain a nice social life on a budget.
The first thing I did doing my homework and finding a reasonably priced accommodation. I found a nice accommodation for £111 per week, while some of my friends didn’t do as much research and ended up paying upwards of £180 per week for their accommodation.
Secondly I found a job ASAP. For the whole of my studies I have worked for LJMU as a student ambassador, which is a role all LJMU students can apply for. I also sometimes do the odd shift for UNITEMPS which is LJMUs own student recruitment team that give students jobs around campus. All students jobs for LJMU pay at least the living wage, which is above minimum. During term time I average 15 hours a week and work more outside of term. Doing that has meant I have never really struggled for money or had that ‘skint student’ feeling.
Also I had to get serious with budgeting. I send myself a set amount of money at the start of the week and I stick to that no matter what. This stops me impulse spending on silly things and stops me from feeling broke at the end of the month.
Basically what’s I’m saying is it’s definitely do-able. Of course the choice is up to you and I understand it’s definitely harder when you don’t have the support of your parents. You can have an amazing uni experience living at home or living on campus, do what feels best for you!

LJMU Student Ambassador.
