That's not all that accurate either.

I needed a credit check for taking my company pension last year, I suggested they used my last address in the UK (from 10 years back). Worked just fine, just use your last known address, nobody updates anything as far as I can see.

until you win big on UK lottery...now I send money to AN Other  he puts the lottery on for me

I'm guessing that should be "domicile", and there's no such rule.  In fact, domicile is extremely hard to lose.  One can live abroad for decades and still be UK-domiciled in the eyes of HMRC.

There's a huge difference between 'domicile' and 'resident'. It's very difficult to lose domicile status which means the Revenue will/may always have an interest in you. Not to be confused with being Non-resident.
