Depends in your up north, in the middle or down south.
We (currently) have a joint income of £60k+ and it is about joint when you're married with three kids, and that's ample to live in a nice town, in a nice big house, own two cars and have a couple of decent holidays a year but then I live in Mid-Staffordshire which makes my mortgage about £100k less than the same house in a nice part of Soton for example.
