Hi there both,
Its great to hear you/your son are thinking ahead and getting organised, and that you're both considering Bath in your choice mix.
I can't speak for King's, LSE or any other choice, but here are just a few observations about Warwick VS Bath:
Bath is a lively city which, although small, is full of great things to do and see - prim georgian architecture, green parks, shopping, coffee houses, street food, pubs, a few nightclubs and axe throwing, and is very well transport connected to Bristol and London with a bus station and a train station right next to each other. It is one of the safest uni cities in the country and the uni has also got one of the best industrial placement schemes in the country. However please be aware there is a small bus ride between city and uni as the uni is up a rather large hill! Also be aware that Bath is quite an expensive place to live, although there are plenty of ways through this in terms of student accomodation.
Warwick is also high-performing for politics/econ and has a gorgeous campus with plenty of green space, a bit of wildlife and with modern buildings (also a very good business school!). The campus is on flat ground and so it is possible to walk to the local shops in Cannon Park centre outside the uni (theres a Tescos, an Iceland and a Greggs among others there). However the nearest city is Coventry which you'd probably need to get a bus to as its not as close to the uni as Bath is to Bath uni. However Warwick aren't as well-known for placements as Bath, although many of their courses do offer them.
At the end of the day its about A) what course you want to study more, B) where you want to be/campus/city vibe, C) how far away from home you'd be happy to be.
I hope some of this helps, and best of luck in all of your choices! 🙂
