£500 million over 60 million people over 10 years is £1 per person per year. I can believe it.

67 million people (as of 2020, so probably not far off 70m now)

But we had to spend 1.7 billion. So looks like we need to wait 37 years for payback…

I don't know if the UK government paid the full amount, but £50 million a year for £1.7 billion is a 2.9% interest rate, which is approximately sensible.
