Earlier quoted context omitted.
> collect money from UK citizens This is quite obviously incorrect. I am a UK citizen, but live in the US. No company needs a UK presence to collect money from me.
And to be clear, that’s still true for selling services online to UK citizens who are also UK residents, it’s not a quirk of you having moved away from the UK - it’s just not true that you need a legal presence in the UK to serve customers from the UK.
But we're clearly far beyond that here.
