Non-UK resident (but UK (BC) passport holder): Bank interests received subject to tax?

Hi, I am a non-UK tax resident with UK passport residing in Hong Kong. Currently, I am receiving rental income from properties in the UK, bank interests from a UK bank account (where I put my rentals) and bank interests from a bank account at Isle of Man (where I put my income from Hong Kong). Apart from the above, there are no other UK-sourced income. I understand that the rentals from UK properties are subject to UK income tax with personal allowance. However, I learn from the Guidance "HS300 Non-residents and investment income (2024)" that bank interests are "disregarded income". Does it mean that i can exclude bank interests from both UK bank account and Isle of Man bank account from my tax return? Thanks.

Hi,
You are not entitled to personal allowances as you are a resident of Hong Kong, you will therefore need to declare all your UK income on the tax return.
Thank you.

Not HMRC...HMRC Incorrect, all British Citizens can claim personal allowance per https://www.gov.uk/tax-uk-income-live-abroad/personal-allowance
