Good luck with them leo. I had SSE.L for over a year in my ISA, but it didn't move much and the main profit was from the dividend in the end so I ended up getting rid of it, but that was last year. If it holds up during the current panic it looks like your target is certainly reachable for it.
Having just thumbed through the SSE web site, I'm hoping this is going to be a good move, since they are a major nat-gas provider and storage.
