Recommendations of UK InDesign courses that you have attended?

Hi everyone,

I have recently started using InDesign at work for various literature projects and feel as though I have good beginner knowledge but would love to expand this both technically and creatively. Can anyone recommend any UK based courses they have been on, preferably around the Midlands area but don't mind travelling? - there are so many out there that come up on a generic google search!!

Thank-you in advance.
