Yeah, British internet can be fairly inconsistent. I'm in a rural-ish area and can get 100 megs down on a fibre-to-the-house connection, but when I lived in an actual town I would be lucky to get 2 megs down on a good day. I literally ended up doing everything over 4G back then because the fixed internet connection was just abysmally bad and Openreach never cared enough to fix it.
