North of the wall all state schools are run directly by local authorities which (should) mean proper backups are in place and any ransomware attack is doomed to be an irritation rather than a disaster.
I've heard some real horror stories from guys in the south about free schools i.e. IT run by the pupils. I wouldn't be shocked to find out some of those schools has paid up in ransomware attacks.
Smaller independent schools are probably at much greater risk as well.
