We live in a Manchester suburb close to two tram stops and the M60. You can get an off-peak Metro day ticket for around £5 and tram about all day to your heart's content. Similar sort of thing with the buses, depending on the company.
We have bags of free museums, regular events of all kinds, art, culture, concerts, universities etc. The Northern Quarter for hipsters, the Trafford Centre (free parking!) for chains. A few lovely National Trust places dotted about. Admittedly it's been years since I went to London but we don't have the same huge volume of people, commuters and tourists, as down there. And of course Chester, Leeds or York are not far away, or there's the Lake District or North Wales for more rural trips.
Parking - NCPs are NCPs and city centre parking is never cheap. But our village car park is mainly free, for instance. And there's loads of public transport, kids under 5 travel free.
Our nursery costs us £37.50 a day. Cinema is around £8, depending. The last time we went swimming at our local council-run place, which is admittedly crappy, it was about £8 for 2 adults and one kid. Dining out will generally cost between £8 and £12 for a main meal.
I used to work for a national supermarket chain and pricing was done by size of store ('band') rather than location, but that could vary by supermarket and also be very different now! We spend about £70 a week for the 3 of us on food and household at Sainsbo's, but you could go a lot cheaper at e.g. Aldi or Lidl.
Our 4 bed semi cost £250k 6 years ago. Hairdressers - non-chain local ones can be very cheap, like £15-£20 depending, Toni & Guy and that lot are much more expensive. Plumbers roughly similar to yours. Window cleaners are £7 every fortnight.
Where we are, a 20 minute drive takes you into the countryside with local farms and farm shops, tea rooms, country estates, riding and all that jazz.
We like it here :)
