As soon as you touch any connections to it, they will leak as well.

I would always recommend getting Worcester in on a fixed price repair.

They made/designed the thing, let them have the hassle of fixing it

Forget fixing the leak with epoxy, the hex is bimetal.
Lots of heating engineers find it a hard job, I really wouldn't recommend it as a diy for someone with little experience or knowledge.
