Computer Science in aston or UWE Bristol

I am an Electronics engineer and would like to apply for a master's degree in computer science or information technology.
But a little bit confused about what university should I go.
Which one is better Aston or UWE Bristol or Bournemouth.
Thank you for your help

Strictly speaking, as you have a background in engineering (I presume you have a degree in it as well), you are more or less eligible to go to any uni that offers computer science as a master's degree (you might not be eligible for advanced computer science though).

I think the more appropriate question is which unis have you looked so far and why did you picked those unis above? They're fine unis by the way, but they're not the only ones offering MSc CS or IT.

Can you explain why you said I might not be eligible for advanced computer science ?
The reason why I picked those universities above is the low fee of study that offers compared to others.
Could you advise me unis with low budget ?
Thank you for your time.

Advanced computer science degrees are degrees that build on what people have learned in their CS/Maths undergrads. If you haven't done an undergrad that has a lot of CS content, then you're not likely to be eligible. Having said that, this depends on the individual degree course.
See the following for example:
https://www.ox.ac.uk/admissions/graduate/courses/msc-advanced-computer-science - CS or maths undergrad
https://www.ncl.ac.uk/postgraduate/degrees/5178f/ - undergrad with significant computing component, which can include engineering
https://www.birmingham.ac.uk/postgraduate/courses/taught/computer-science/advanced-computer-science.aspx#EntryRequirementsTab - computing or a closely related discipline.

Unfortunately I don't know of any from the top of my head. Can I confirm whether you're eligible for Student Finance in the UK? If you are, then you should be able to get student loan to fund your MSc without much concern for how you can fund your degree. Unless you specifically want a degree with low tuition fees to avoid the student debt, then I would advise to look for a degree that you would more to your liking.
Do also note that you can sometimes get scholarships and access to bursaries to help fund your degree as well.

If you need me to help you look for degrees with low tuition fees, let me know.

Thank you for your offer to help. Yes, I'm interested. Can you please provide me with more information?
