England ran in four tries as they beat Scotland, with Henley's Danielle Waterman marking her return to England colours with the third score.
England's other tries came from Michaela Staniford, Nicola Crawford and a penalty try, with Lindsay Wheeler crossing for the hosts.
"Because of the cold and windy conditions it was a bit of a scrappy game," said coach Geoff Richards.
"But we are still on course for the Six Nations and Grand Slam titles."
