PeterPedant please can you clarify why that links suggests trouble? It looks okay to me

"Check your passport's validity
As the UK is no longer part of the European Union, most EU countries now require UK passports to be less than ten years old and still be valid for at least three months at the time you're due to leave their country. Just so you know, if you renewed your passport before your previous passport expired, any extra months that may have been added to your new passport’s expiry date, making it valid for more than a ten year period, may not count.
For example, a passport with an issue date of 1 January 2012 and an expiry date of 31 October 2022 isn’t valid for beyond 1 January 2022, ten years from its original issue. Check the date of issue on your passport to work out whether it meets this criteria and make sure your passport is valid for travel here.
