Whether you receive DLA or not is not relevant to your husband's DLA renewal, so you should not worry about this.
You need to explain why he needs to get up, why he cannot use an appliance instead of the toilet, why your assistance is needed to help him to the bathroom, it is essential that you show this assistance is actually required, so you need to document what problems he would have without it, help that is provided but not shown to be required is unlikely to count towards an award.
