"although many wouldnt call themselves religious that does not mean they do not believe in spirituality"
Yes, that is quite common in the Christian world, where quite a few people born to Christian parents have gone into other spiritual practices like Wicca, etc.
I have never seen that in the Muslim world, except if you are talking about belief in astrology etc. Ime, people of Muslim heritage either follow Islam (or rarely, convert to another religion "of the book" and follow that) , or just not call themselves "spiritual" in the religious sense. I have never seen or heard of a person born to Muslim parents, who then went on to call herself a white witch or whatever.
"I have friends who cover and pray when they can who wouldnt call themselves religious"
Muslims? How do they not consider themselves religious when they are praying to Allah in Arabic, quoting verses of the Quran? 
"Has anyone got the stats for the percentage of Muslim reverts who revert while in University?"
I wouldn't be surprised if there are a few. Just like in the army or prison, when people congregate in close quarters for several years, there is significant exchange of ideas. The university I went to was known for being a communist hotbed and many of my classmates were "converted" to this worldview.
Anyway, the negative correlation between education and religiosity is very well researched and documented, if you are interested to find out more.
" it is not the uneducated parents from towns and villages who are trying to involve themselves in learning and practicing Islam, it is their kids who were born in London, university educated, living a decent lifestyle"
2nd or 3rd generation immigrants trying to get back to their roots & showing interest in religion is also a well documented phenomenon.
In general, however, you will find that as education and living standards in a given area increase over decades, religiosity decreases. On top of the global decrease in religiosity that we have already talked about.
