It's early days, but so far as I know, apart from the occasional security exception (not many Libyans on Nuclear Engineering courses) UK universities have never had any problem with foreigners.
But, you would need to spend a certain amount of time at the university (probably 2-4 weeks per year) to do the essential labwork, and presumably would get no subsidy from HM Government. (Before you ask, at the moment I don't know what it would cost, and can only suggest looking at the cost of general Engineering degrees on the OU website for a rough idea).
