Every month, YouGov identifies the brands generating the strongest surge in consumer conversations in the UK.
Using data from YouGov BrandIndex, our daily brand tracking solution, we measure Word of Mouth, the percentage of people who say they have talked about a brand with friends or family in the past two weeks.
The brands featured here recorded the largest increase in conversation levels over a four-week period, calculated as the difference between their lowest and highest Word of Mouth scores during that time, using a four-week moving average.
Word of Mouth marketing: Brands recording the greatest growth in March 2026
- Brewdog: +6.8 percentage points (from 6.4% on March 1 to 13.3% on March 30)
- BBC News: +5.6 percentage points (from 9.2% on March 2 to 14.7% on March 29)
- BrewDog Bars: +5.5 percentage points (from 4.6% on March 2 to 10.2% on March 30)
Together, these brands drove the biggest shifts in real-world brand conversations this month.
Methodology: March 2026
Word of Mouth scores are based on surveys of adults aged 18 and above, conducted between March 1 and March 31, 2026. Each score reflects a rolling four-week average, meaning it is calculated using data from the previous four weeks. It is measured as the difference between the lowest and highest points within the four-week window, with the lowest point occurring before the highest. Only brands with a minimum sample size of 100 respondents are included.
