Under data protection legislation you can get a copy of the information you gave to the surveys. Everyone has the right to access any personal data that is being kept about them. You can do this by making what is known as a subject access request. You should send your request to firstname.lastname@example.org
Additionally, you can download the study data from UK Data Service by registering and signing the special confidentiality contract. However, unless you are a professional researcher the data may be difficult to understand as they are in a complex format. And you won’t be able to identify yourself as the data are de-identified.
