PS Larkswood I thought about your UK government pension lump sum. I don’t know much about this but believe they can be very restricted as to lump sum and transfers.
I thought the same as George1 ie “you’re st***ed”. But then I saw you have time and other sources of income.
If it was me I’d be looking year by year at any useable lump sum (bit by bit) or even partial transfer opportunities (bit by bit).
Also would some of those schemes have opportunities concerning spouse or dependents. Get hold of their uptodate small print and scour it. If at some point in the future you might decide to volunteer your skills in, say, Botswana either within a paid framework or unpaid depending, effectively residing there and having declared, ideally on 1st Jan or, to make sure, on the last working day of a previous calendar year, that you will be doing this from 1st Jan for a while tbd, it’s close in terms of other things for some but it looked like there might be a window after, say, 3 years. There might also be privileges if you became, say, a diplomat or some sorts of UN or similar employee. Wondering if DOM have any privileges
