I also live in the UK. The last few years I’ve been tempted to buy a portable AC. Just as I go to spend £300, the weather turns and I decide to spend money on other stuff (like food)

We had that heat wave just after Easter this year, much earlier than I remember, that was the final straw. Bought one on marketplace for £180.

Every night going to bed the sheets are crisp and cool. I sleep like a baby.

The biggest downside? Damn those things are pricey to run
