DST - welcome to the forum!
If I were you I wouldn't go as far as Dundee. Spending 2h40min travelling by car for every hour you're in the air, then finding when you get there that there is a problem with weather / airport / aircraft / instructor so you can't actually get up would be pretty tough going - your motivation could be tested!
If you're thinking of this as a hobby, then I'd look at a more club orientated location rather than simply a school. You'll find more people to chat to / help you / fly with, even at the quieter clubs. I learnt and still fly from Prestwick Flying Club and enjoy the chat and atmosphere - I recommend it but I'd again say it is probably a bit far for you.
It is worth thinking about where you want to take your hobby. Once you've finished your training, will you still have money to fly? Are you always going to hire an aircraft or join a group / buy your own? Do you want to fly out with others?
I'm a pretty new PPL but am in a group at Prestwick. If I wasn't in a group, I'd certainly be looking at 3-axis microlights. I hear very good reports...
