Do any UK universities include PPL/Commercial flight training as part of an aviation degree?
One UK list is here, it mentions several universities that include PPL and/or ATPL training in the degree course, but they appear to cover only the theory part of the courses with actual flight training being optional. Where a full PPL is included, they mention extra costs of around GBP 7000 on top of regular tuition.

If you look directly at the university sites they seem to confirm this: Leeds includes only 10 flight hours for the PPL; Brunel and Salford both include a UK NPPL but at extra cost.

You might be able to get a scholarship of some kind to cover all or part of your tuition, but that depends very heavily on your personal situation and what the individual university offers. Finally, you could consider the RAF as an alternative route to paid flight training but I have no idea if that's of any interest to you and I imagine that competition for cockpit places is very tough.
