moving help

hi, we are moving to our first bought home in june and just wanted some advice on what we need to do. we are currently renting and have gas and electric from british gas, do we need to cancel this before we go and take on current houses suppliers or do we tell british gas we are moving. I have looked on comparison and its cheaper for us to switch to sainsburys than stay with bt so when and how would i do this.

Thanks
