These discussions are always very annoying. People tend to state their preferences without mentioning their latitude, their longitude, or their current time zone.
Anyway, here are my preferences: GB should switch to UTC+0 all year. UTC+1 all year was tried (1968-1971) and was very unpopular in Scotland. School hours are roughly 09:00 till 15:00 and they only get about 6 hours of sunlight in winter up north so local noon has to be at around 12:00. Also, for political reasons relating to Northern Ireland, it is very helpful for GB and Ireland to have the same time. So UTC+0 it is.
Seasonal changes in school hours is a theoretical possibility, but parents of schoolchildren have a hard enough time as it is and lots of other things are linked to school hours. It would be much easier for everyone else to make seasonal changes to their timetables, like just get up an hour earlier if you want to. Nobody's stopping you.
