Your £150 can be spent on pre-paid Oyster (TfL) credits.

Travel in London can be costly, and we'd like to offer you £150 oyster card credit and help you get to and from the University without having to worry about travel costs. This is only available as top-up credit, so if it's monthly/yearly (student discount) travel you are after, this might not be the right option for you. So choose wisely!
