Methodology:
YouGov BrandIndex collects data on thousands of brands every day. Holland & Barrett’s Ad Awareness score is based on the question: Which of the following retailers have you seen an advertisement for in the PAST TWO WEEKS? Scores are reported as percentages, based on daily surveys of UK adults. Data is weighted by age, gender, region, social grade, and ethnicity using a raking methodology. Figures are shown as a 1-week moving average with sample size ranging from 251 to 532 between 1 April 2026 to 19 April 2026.
YouGov Profiles is based on continuously collected data through rolling surveys, rather than a single limited questionnaire. Figures are drawn from responses collected between April 2025 to April 2026, using a 52-week dataset updated weekly. Data is nationally representative of adults (18+) in Great Britain and weighted by age, gender, region, education, and social grade.
