The 26-year-old second rower, who was a member of Saints’ Grand-Final winning team of 2014, becomes Hull’s first signing for 2020.
“When you look at the calibre of other clubs that were in for Josh, it’s really pleasing that he has decided to join Hull FC because it shows where we are at,” said Hull coach Lee Radford.
“I think it’s a really, really strong signing and it’s a great start to our recruitment for next season. I’ve been a huge admirer of Josh for the last few years, so to finally have the deal done is a relief.
“Josh has the attributes to become a regular in the England squad which is hopefully an aspiration we can help him achieve.”
