Here's a chart of what I am talking about
I've used the site inflationtool.com to get the relative values. Of course it's all relative but good enough to get the idea.
The chart shows the decline over the last few decades. But one thing that really jumps out for me is the last two years according to this latest AGM figures report (not that I can work out much from them). Last year's turnover was 13% down on 2017 and in 2017 there was over 100 grand surplus. This year turnover is down but expenditure is up resulting in a 25 grand loss.
But if you look at the relative size, the amount we were paying to the bank for the mortgage would almost cover a year's worth of turnover. Bad signs or good?
