The 29 year old initially joined Gloucester on loan in the spring of 2010 from Championship side Nottingham but quickly impressed and earned himself a permanent contract.
Initially a member of the Leicester Tigers Academy, he also spent time in New Zealand playing for Nelson Bay as well deputising for Dan Carter at the Crusaders.
Tim has been a regular in the first team squad at Gloucester and picked up an LV= Cup winners medal in 2010-11.
He has been sidelined with a thumb injury since the turn of the year but still possesses the third most accurate kicking percentage in the Aviva Premiership this season.
Talking to the club website, he explained that he's delighted to be staying at Kingsholm and is looking forward to the next couple of years for more than reason.
"I'm really happy. I've enjoyed my time with Gloucester and it's great that I've got the opportunity to stay for another couple of years.
"This season has been a bit frustrating with the thumb injury but I'm almost back and hope I can play a part in the run in.
"It's good to have some stability as I'm shortly starting a new personal training business alongside Ed Archer (formerly on the strength and conditioning staff at Gloucester). I'll be working out of the Lion's Den so I'll seeing more of Kingsholm than most of the boys!"
