How effective is Baritsu?

Baritsu is a martial art invented in Victorian England. It is derived from savate, judo, pre-Queensberry boxing, and traditional African stickfighting. I used to practise taekwondo and fencing but due to a foot injury i must now walk with a crutch (dropped a cabinet on my toe and broke several bones). How effective is baritsu for self-defence? Is it easy to learn? Are there any websites offering tutorials? And where can i learn it in Norfolk?
