Trinity College Dublin has many excellent degrees for about 2700 quid per year, the rest of the life in Dublin is very similar to say, life in Sheffield.
Allegedly, if you get a job in McDonalads in Holland somewhere, for at least 3 months, then the Dutch government will pay you a grant for the entire three year course at Delft (best Dutch uni) or Amsterdam etc - I dunno if this is true. Otherwise they are great value in NL even without a grant.
Sweden is very good tuition (almost if not totally FREE), very reasonable prices, obviously travel & living costs are higher.
What about studying on the island of Venezia? (the University of Venice "Ca'Foscari" accepts UK students for several courses) a few hundred places available, fees seem to be less than 2 grand a year, in Venice! there are some other very interesting places out there. . .
I have to say, these foreign options arent for everyone, its probably only suited to the students who have already holidayed abroad on their own, and know a few of the pitfalls (like prosecco being 5 euros a bottle in Italian supermarkets) And surprisingly many European students have the opposite idea to British students, in UK most people choose a college a few hours away from home, for the freedom, fun and the courses. Most Europeans just choose the closest college so they can stay at home, minimise costs.
Some UK universities are amazing value for money, even today, internationally. Oxbridge/Durham/St-Andrews/Glasgow/Edinburgh etc etc would all cost ten times more if these were US universities. Difference is, all Americans grew-up knowing that college cost $100K, so almost from birth the (sensible) parents started a savings plan-college fund for their kids, whereas in UK it has suddenly started to cost 9 to 10k, in the last few years meaning there was never time to budget beforehand.
