You will need a written record of the consultation responses. Think of the easiest method for your community to feedback but also ensure it is an efficient method for you, as you will need to collate this information as evidence in your application. We would suggest creating a survey, questionnaire or petition that can be accessed online and also replicated by creating paper copies for those who do not have access to the internet or IT. We have created some example questionnaire questions. Google Forms is a free tool that you can use to create a survey and collect responses by sharing a link.
When asking people to complete the survey/questionnaire/petition include a question to ask for the consultees email address and if they give permission for you to include them in the newsletter mailing list.
