You do t need to call them - although you can, for reassurance if you want to. If you don’t have, or do t know, your tax code, ask them to tell you.
What you need to do is wait until after the end of March this year, register for self assessment. You will then be able, anytime between April 2023 and January 31st 2024, to complete a self-assessment tax return.
You add up how much your overseas pension was between September 2022 and March h 2023 and put that in the foreign income section.
There is space on the form for your UK income too (so other pensions, interest on bank accounts etc)
You will then be shown how much tax is due, and can pay it immediately.
It is very straightforward and simple.
