I think just 'doing things' in general seems to be cheaper.
As a disclaimer I don't live in the north of England, but I live in a very cheap area in the midlands. I was born in Stoke-on-Trent.
When I used to go to London, i was shocked at the prices of just doing something, like say getting food.
For example, near here I go down a high street and see a sign, 50p for cobs (sandwich/bun) or £2.99 for lamb chops, green beans and mashed potatoes. Whereas in London I remember going into somewhere and seeing approx £12 for an English breakfast which shocked me.
But then I'd imagine bills are quite similar anywhere - mobile, broadband, gas, electricity, water (apart from in Cornwall I've heard!), TV licence, prescriptions, landline, all of those are going to be similar. Msybe service charges and ground rent are different, I don't know.
I was just shocked by random items I guess. I went to visit my sister in Stoke Newington. I thought it was really nice, I can see why she likes it there. But then going down the high street, there were lots of little shops, they were lovely. But say buying a plant (cactus) from one of them was a SHOCKING price, or say going into a stationary shop and there were three rolls of sellotape for about £6.99, I was stunned.
The bus was a lot cheaper. Here it is £4.50 for a daysaver which I find a lot. So it was like, people would either stay where they are, and they can buy a top (T shirt) or get several items from ASDA, or they can travel on the bus to go somewhere. But if you're on a budget, that's a high proportion of your spending. In London the bus was £1.20 if I remember rightly.
In London I felt that I was more accepted, it was more anonymous, no one cared, no one was judging, it didn't matter if I wanted to wear something totally crazy, no one would look or judge. I felt there was more choice of things, so if I had a niche interest, there would be a club or something I could go to. Every event I see online that I like the look of, it pretty much is in London. So there felt like there was more opportunities, choice, things to do. But at a price.
Things that are cheaper here: for example drinks in pubs. So when I went to a local pub, asked for a small lemonade in a glass and it was 85p. But in both places there are cheap items to be had.
I think I mean just 'going out for the day' and being stunned at how much money you can get through. But then there were free exhibitions and things too.
Thete is also variety e.g. I can get 3 diet cokes for £1 in one shop yet I can go into another and get 1 diet coke for 85p. This applies to both places, so sometimes things aren't a true judge of a place if you just take a one off.
But then I'm sometimes shocked by things here. E.g. saw a tube of Colgate toothpaste for £4 in a shop. But then the same thingis £1 down the road.
If you go into random shops in London you can feel priced out. E.g. walk into a clothes shop, can't really afford anything in there. Whereas here, walk into a clothes shop, you can afford it all but you might not really want to buy it!
Going out for a meal is LOT cheaper, as in stunningly cheaper.
Buying drinks is cheaper, in some places significantly cheaper.
Random shops on high streets are WAY cheaper.
Things like swimming - I am not sure. Have seen some expensive prices. The gym is £10 a month approx.
It depends what you want to do. Look at a breakdown of your typical month. See the sort of things you do and the things you spend on. What are they?
