I saw people discussing how English homes are insulated to keep them hot in the winter, and this is hurting them in the summer.

Either I am completely retarded or the internet has basically let the lowest common denominator have a voice.

Insulation only works till the building is heat soaked then it makes it slower for the building to cool down and our houses are typically brick which holds heat well, uk houses have low airflow because it’s cold and wet much of the time so in summer the issue is that heat gets trapped in the day and we can’t get it out at night.

It’s currently about 6 degrees warmer in my bedroom than outside but with no wind I struggle to get the heat from inside to outside.

The discussions I've seen have been more about how the buildings are meant to keep the heat in vs letting it go, either by building with less thermal mass or with airflow. Once stone or concrete buildings heat up, they tend to stay hot or vice-versa.
