age rating for our film

As a group we decided that the best age rating for our product would be a 12A. It was either a 12A or a 15 in our film there was no reason that our film should be a 15 because there is no physical violence or strong language. We thought that 12A would be better since it would be the adults choice if they want their kid seeing our film. I think that since there is no strong language, sex or violence there is no need for it to be higher than a 12A.
