When they say its grim up north do they mean scotoland?

The phrase "it's grim up north" typically refers to the perception of the northern regions of England, particularly areas like the industrial cities of the North East and North West. While it can encompass a general stereotype about the weather and economic conditions, it is not specifically about Scotland. Scotland has its own distinct cultural identity and challenges, so while it may share some similar weather patterns, it is not the primary focus of that saying.
