There's posh jenpax I grew up in Yorkshire where we had breakfast ( pronounced brake fast) dinner at midday then tea at 6pm. Supper was a movable feast.
I think high tea is probably something remembered only by an older generation, I haven't heard the term used for years.
I remember it as being a veritable feast though with a cooked dish and cake or trifle.
