Lucy Rochford


Lucy qualified in Nutrition and Dietetics at University of Surrey and began her professional career working in the NHS, initially, as a dietician and subsequently as a public health nutritionist. She later went on to undertake an MSc in Public Health Nutrition at Southampton. In 2001, Lucy moved to PAGB, initially advising on and approving consumer-facing advertisements for over-the-counter (OTC) medicines, food supplements and traditional herbal medicines; and later managing a team whose role it was to provide this service. The aim was to ensure that the various codes of practice and regulations were complied with, to promote high standards and to enable members to avoid advertising complaints. Lucy was also responsible for producing the various PAGB Codes and advertising guidelines; defending PAGB-approved advertisements against complaints, being a member of the Committee of Advertising Practice (CAP) and being part of the working group that was responsible for updating the CAP Codes.

After leaving PAGB, Lucy set up a company called ‘Advertising Health Check’ and now works with consumer healthcare companies, advising them on their advertising and helping them comply with the various codes and guidelines in order to promote high standards and avoid advertising complaints.
