I'm currently attending the college, and we were given 1-2 weeks holiday at the end of the basic course (depending on what discipline you were selected for) and also had bank holiday Mondays off.
Just a word of warning though - if you are trying to plan a holiday during the course - don't book anything up until you know your timetable and have spoken to the course delivery support staff. I say this because our course was subject to timetabling changes including the course being lengthened by a week. Some TATCs were planning to go away / had booked holidays for the original break, and were disappointed when the dates were altered part-way through the course. My advice is to wait until you get to college and then book something fairly last-minute when you know for sure your holiday dates!
