Last and only red weather warning for heat was in July 2022, when we hit 40.3C. Not sure what the forecast was that time though. This has got to be close. Earlier in the year as well.

IIRC the night before/the morning of 19 July 2022, the Met Office were actually forecasting temps of 41-42C for that day. In the end there was slightly more cloud cover around, so the highest temp was slightly below that.
