I don't think you have to be especially innovative.
What most people don't understand is that to become rich is not necessarily in the idea, but in the execution of the idea. I mean you can have an average idea, but make an excellent execution of it and you'll get money. You can also have the best idea of the century and make some shit of it.
By the way you'll be surprised how many hours some 'new richs' work everyday (I know two 'new richs' as they're called, and I can say one is barely working 2 hours a day).
Nobody here is going to tell you how to earn 1,000,000£, just search by yourself and I'm sure you'll find.
