There's also the OPen University who are always looking for tutors, and you have the added advantage of teaching people who want to study.
Trust me, Higher Education isn't any better. Maybe the OU gets a different type of motivated student (possible) but Universities are filled with 'clients' (they pay to study, we're told they are our customers) demanding their 2.1 and constant spoon feeding (the government's aim to out 50% of the population into Higher Education is one of the stupidest things I've ever heard).
Add admin, pastoral duties and the constant pressure to bring in hundreds of thousands of pounds in research grants and HE is a pretty horrible place to teach as well. And we don't have the holidays... :)
