Hi Federica Pojaga,
You would need to consider your residence position in the UK.
Please have a look at the guidance here:
Residence, domicile and the remittance basis: RDR1
And the tests here RDR3:
RDR3 Statutory Residence Test
If you are treated as resident in the UK for the full tax year, then as you have lived in the UK for more than 15 of the last 20 years, you are resdient and deemed domiciled.
This means that your are taxable on your world-wide income arising while you are resident in the UK.
