Here’s an interactive map showing incomes in each parliamentary constituency in 2020/21, shaded by median incomes. You should be able to zoom around with your mouse/fingers, and if you hover/touch a constituency you’ll see the full data, broken down by employment income, self-employment income and total income tax paid:
You can see a full-screen version here, and the source code is here.
If we shade by mean income, instead of median, the map turns entirely white (and you have to zoom into central London to see any colour). Which tells us something about income inequality:
There are some big caveats here. It’s data from income tax only, so won’t include capital gains. The sample size per constituency is small, so the accuracy won’t be great. Both these reasons mean that very high earnings likely won’t be captured.

Interesting to see the distribution. I wonder if you can join up with the LSE work on income distribution? From memory at this IFS conference they were able to say how much income you would need to be in the top 0.1%, 1% etc by geographical area and by occupation.

I wonder if there is any correlation between income and the number of disguised remuneration loan charge letters that were sent: https://www.gov.uk/government/publications/disguised-remuneration-loan-charge-awareness-letters
