These threads always amuse me because there is such solid data for average (median) UK salary and you can very easily find the splits for region, profession, educational background, age etc. But I'm going to join in anyway. 
I'm in London and earn around £55k. It's more than I ever expected to earn, and more than others in my life (outside of colleagues obvs). But as a lone parent without family wealth? I have a lot of month left at the end of my money. My housing costs (literally just rent/mortgage/service charge, not including other bills) take about 60% of my net salary, for a fairly small flat in a fairly rough area.
But if there were two earners in my household, even if the second wage was much lower, it'd be a different story.
The london weighting component of my salary is small, so if i relocated to another city, it'd be a different story.
If I were 10 years older and had got onto the housing ladder 13 years ago rather than 3 years ago, my monthly repayments would be much smaller - again, different story.
So - I know it's a good salary (other than by MN standards
) and I know one day - fingers crossed - it'll feel like that. But crazy housing market in the place I'm from + crazy childcare costs means I still need to live frugally and (other than my pension) won't have anything like 'savings' for many years yet.
