automatic enrolment Pension letter

I have just been reviewing the content of the AE pension letter. It states that it is new legislation, but as that was in 2015 it is no longer new.

Also it states that the payments from wages will betaken on your  next payment date following the 01/10/2015. As all our new starters have a 3 month wait to be AE, this is not correct  and also it is not accurate as new starters generally have different start days.

Is there anyway this can be changed?
