Hey there and welcome to the Samsung UK and EU Community Customer to Customer Forum
This will depend an a few things, and a quick search of the forum may have provided you with your answer.
Where did you buy your device (retailer not country)? If UK based retailer (not amazon or ebay) then your device will get the update when Samsung release it for your CSC code. We do not have a list of codes and dates so cannot confirm a date for you.
I am not employed by Samsung nor do I receive any remuneration as a Samsung Members Star.
My device is an S25 Ultra.
