England emerged 17-10 winners against reigning champions Ireland with tries from Sarah Hunter, Kay Wilson and replacement Marlie Packer at Twickenham on Saturday.
The triumph was England's second successive win in the Championship after they downed Scotland Women 63-0 at Rubislaw.
And after getting their campaign off to a losing start against France, Scarratt insists they have turned a corner.
"I'm thrilled," she said. "We really needed to go out there and get a result because we didn't really start the Six Nations the way we wanted to. Now it's really important that we kick on and get on with what's left.
"You'd want to win every game by 40 points of course, but international rugby isn't like that - Ireland won the Grand Slam last year.
"Of course we'll take 17-10. It's about our performance as well and we know we've got a lot more to come, which is good."
