Sole trader - foreign vs. UK income

1. I am a non-UK national residing in the UK since 2 years back 2. I'm planning to set up a Sole Trader business in the UK and start working as a self-employed consultant 3. If I move out of the UK and become a non-resident for more than a tax year, to travel and work remotely like a digital nomad, will the income I earn and invoice through the aforementioned Sole Trader business count as" foreign income" or "income earned in the UK"? Does it make a difference if I am invoicing UK-registered companies or foreign companies? My underlying assumption is that I wouldn't need to pay UK income tax if my income counts as "foreign income".

Hi eu.felicita,
Please refer to: Tax on your UK income if you live abroad.
Thank you.
