Oh, I don't know much about Uclan but it depends on whether you intending on moving or not, seems to me to you want to stay local.
I am somewhat in a position somewhat similar to you, I just finished college, did alright but didn't do maths. I could have either done maths in this one year or applied foundation year. I decided on doing the foundation year because as mentioned above, maths can be seriously a large workload and hard, so I didn't really want to risk it and applied for the foundation year which allows me to retake a few exams to improve my grades a little and is far far less risky but it does add 9k to my debt lol.
Whatever you do, post on here if you need anything, amazing people are on here and are willing to help you out! I hope you succeed, you really some motivated to do well and become a good engineer!
