It's a newish area, many universities offer a more generalised music production course but some are starting to offer a specialisation but the courses may be pretty new which means you may not get many reviews.
But I'd recommend looking at
Guildhall School of Music & Drama (Electronic & Produced Music)
Leeds Conservatoire (Electronic Music Production)
Waterbear Brighton or Sheffield (Electronic Music)
Southampton Solent (Digital Music)
Brighton (Digital Music & Sound Arts)
