The Tigers acting head coach will give first starts of the Guinness Premiership season to Andy Goode, Tom Croft and Matt Smith.
Fly-half Goode missed the opening-day win over Bristol after failing a late fitness test which allowed Smith to step up and claim a place among the replacements. The 21-year-old, who made his Tigers debut last season, played half an hour of the game at Bristol and retains his place as Ayoola Erinle is ruled out.
Croft comes in at blindside flanker in place of Owen Finegan in the other alteration to the starting XV.
"The Erinle change was forced upon us, but I have made a call on Andy Goode, who would have started last week, and Tom Croft," said Cockerill.
"The tactics and the commitment were perfect last week and we need them to be spot-on again because we know Bath are a good team and they enjoyed a good win over Worcester last Saturday.
"This is our first home game of the season and that is important to us. The guys are all looking forward to getting out there in front of the Welford Road crowd again."
