Burns is in line to face Toulouse in Round 6 of the Heineken Cup this weekend and he is delighted to have secured a new deal.
"I'm very pleased to get it done and can now look forward to the rest of this season and the next two after that," he said.
"I think I'm becoming more consistent in my own game and I'm starting to build key relationships with the other players.
"I'm happy with how I've been playing for the past few weeks and hopefully I can push on now and keep developing as a player in a Gloucester shirt and help the club to achieve bigger things.
"There's always talk about other offers being out there and it's flattering to hear that other clubs have got their eye on you but my heart's with Gloucester and I always wanted to stay.
"I came here from the Bath Academy and Brush (Bryan Redpath) was the man who gave me my shot. I'm settled here, it's a massive vote of confidence that Brushy and the board have placed in me and I intend to repay that faith."
