Having spent his playing career to date with his home town club, he admitted to being a little apprehensive at coming into a new environment.
"It's really good. The boys have been really welcoming which makes life easy. I've had a few preseason nerves coming into a new environment at a new club but I'm really happy with it so far."
"Gloucester has a very good squad and hopefully I'm here to help make that squad better and help us strive to win trophies."
He's only had a few days to compare one professional rugby set up with another, Brett was pleased to declare that Gloucester are getting it right off the pitch in his opinion.
"I've been very impressed with the professionalism of the boys. The hard work is there to see."
"Some people talk about Leicester doing more training etc than anyone else, Leicester do this and Leicester do that, but I've come down here and that impression has gone out of the window."
"Barny (Allen) works the guys really hard and I'm sure, once the rugby starts, Brushy and Hoggy will make us work hard too. It's a similar approach to the one Leicester adopt."
Leicester born and bred, he confessed that it hadn't been an easy decision to move on but that he's fully committed to Gloucester now and can't wait for the two sides to meet on the pitch.
"It was a hard decision to leave Leicester. In terms of rugby, I could probably have left a couple of years ago. But I was a home grown lad and wanted to play for Leicester and, obviously with my brother being there as well, I chose to stay."
"But, that's all in the past now and I'm just looking forward to playing for Gloucester now."
"When the fixture list came out, I was straight onto the Internet looking for when we play them. Hopefully, I'll be playing and playing against my brother!"
"I've got it all to prove. People will probably look at me and say 'he wasn't first choice at Leicester and why have we signed him?' My job is to prove to everybody, the fans, coaches and team mates that I'm a good asset to Gloucester."
What was it that persuaded him to pen to paper at Kingsholm?
"When my agent was looking around, Gloucester immediately attracted me because I see it as a very similar club to Leicester in terms of history and tradition. It's a proper rugby club."
"The fan bases are very similar. It's a passionate crowd following a passionate club. I wanted to keep that and I class both Gloucester and Leicester as proper rugby clubs."
"I think we've recruited well. James Hamilton, the Scottish lock who has just signed, is a good asset to have in the pack and we've a number of young lads who are coming through and playing really well so I'm confident in the squad we have."
"I know Jim very well and he actually sent me a picture message of him signing his Gloucester contract! That was quite funny."
"We've been friends for ten, fifteen years now so we're quite close so that was good news for me when he decided to come here as well."
