Home counties, are more expensive, when I go back up north, I find the price of supermarket shop a lot cheaper, I think you don't necessarily notice when buying individual items, as they are 5p-10p cheaper so on first glance looks around the same, but once at the till with a big shop it's significant.
Also eating out in pubs and casual/family restaurants, is so much cheaper.
car repairs, hair dressers ect....
Also compared to the town's where I live, more free stuff to do, and generally more days out stuff to go to.
Round here we are so close to London, its sort of expected you would just go to London for days out. But I don't want to trapes into London every time I take the DC out.
Also up north where I use to live, each town would put on a massive fireworks display to music and bonfire for the 5 November, which was usually free or suggested donations.
Down here massive firework displays cost a fortune to go to, and little local town ones are shit and still cost stupid money to see a literally few fireworks go up.
..............and fish and chips are cheaper and much nicer up north too.
