I suspect that will be replacement switchgear on the right that you'll need.
If you have the BMW warranty, its covered, but will cost the £100 excess, of course.
As an aside, my righthand switchgear also got replaced for my hot start warranty claim, because the extra battery loom fix didn't do the trick.
It's the one warranty thing that I have claimed on - for both bikes.
(Which means I'm not getting good value for the warranty, but I like the security. Odd, really.)
