it is too high for a night flight. BA cabin crew don’t seem to be able to grasp the concept of sleeping under a duvet/white company blanket in 23 degrees. Yes there are other people in the cabin, but it is far easier to stick another layer on and warm up, than it is to cool down - you can’t exactly take your clothes off!

I have seen the policy in writing and I know that it should be set to somewhere around 21 degrees at night. This is still too warm for me, but it is better than 23 degrees. So when the crew told you it has to be set to 23 degrees, then they’re either lacking in knowledge of their procedures or they are lying.

The A380 has underfloor heating in the galleys and the crew (who understandably get cold at night), instead of turning up the underfloor heating, they whack the temperature up in the cabin, but with the curtains closed at night what this does is create a mini sauna in the cabin and very little heat escapes through the thick curtain that separates the galley from the cabin. This, I believe, is the reason they turn it up so much as they can’t feel the effect unless they do so. It’s completely unacceptable and instead of sitting on their jumpseats and getting cold in the middle of the night, they should move around more and wear a jumper. They are after all still on duty at this point.
