The New Zealand-born star hasn't pulled on the Red Rose jersey since the defeat in Paris last March due to shoulder and calf injuries but has been in Martin Johnson's plans throughout.
Johnson will name his 32-man squad for the tournament next week with Flutey, who has seen Shontayne Hape stake his claim in his absence, tipped to make the cut.
"I've got another three games before for the Six Nations but it's good to be back and get through 70 minutes," said Flutey.
"The England management have been great throughout the last year, ringing up and seeing how things have been going.
"I have had the England physios and doctors coming to Wasps once a week to check things.
"All I need to do is get on the field and get game time under my belt - that will give me loads of confidence going forward to the Six Nations."
