Luke was part of the TWRFC minis and juniors before excelling himself at senior level. His flexibility to play either 9 or 10 for Wells was a key attribute in a successful Wells side during this period when the side were riding high in London South 1.
Luke made his Saracens debut in 2010 and has made 5 appearances for the side since then. He has spent some time on loan at Championship side Bedford, who this season are one of Bristol's rivals.
One signing for Bristol, Director of Rugby Andy Robinson said "I believe he'll be perfectly suited to the expansive game that we are trying to play at Bristol,".
"Luke is exceptionally quick and dynamic - he's a constant threat and has shown a high level of consistency in his performances for the Blues."
TWRFC Chairman Graham Withers said "It's always very rewarding to see one of your own doing so well at such a high level. Luke was a fantastic servant to this club and he always has our best wishes."
