Is it normal to invite people to outings without asking?

I live abroad and have a group of friends that includes a few from the UK and some from other countries. Usually I plan outings and we meet up and hang out in a variety of places, from lunch, to swimming spots, to festivals, to museums. On more than one occasion one of my friends from the UK will send in the chat that they are bringing someone, or that someone else is coming too and they hope that's okay, usually the same day as the plan itself.

Where I'm from, this is rude and it frustrates me every single time. I don't object to it in the moment because these people are already invited and they didn't do anything wrong by accepting an invitation. If my friends would ask before hand, in most situations an extra person would be welcome. But they don't.

I've dropped hints that it upsets me and makes me uncomfortable, but before I address the problem, I wanted to see if this was normal social etiquette in the UK. Since more than one person has done this, I don't want to get too upset if this isn't considered rude.

I'm also afraid that I'm just upset because the only time we hang out as a group is when I plan something, and when they bring someone without asking it feels like it's undermining my effort to get everyone together. I don't want to cross wires on the issue, so I thought I would ask.
