You're "annoyed" with a useful service that you didn't even know existed until five minutes ago?
It isn't (though that was what I was expecting); "British" works.
(Though it can't tell me whether I need a visa for Ukraine, so I'm not enormously impressed)
If you actually need to know, rather than that just being an example: you don't. You used to have to fill in a form on arrival, but even that was abolished a year or so ago.
