The ONS data, published on Tuesday, found that about 5.4 million people aged 16 and above in Great Britain (9.9% of the population) used e-cigarettes daily or occasionally in 2025. Vaping was highest among those aged 25 to 34, at 16.4%, making that group the most common users, overtaking 16- to 24-year-olds who had led between 2021 and 2024.
Among those who had never smoked cigarettes, 1.1 million reported using an e-cigarette daily or occasionally. This figure is up from 940,000 in 2024 and marks the first time official ONS figures have confirmed the number exceeded 1 million for Great Britain. A 2024 study published in the Lancet Public Health journal had estimated 1,006,000 people in England alone who vaped despite never having smoked.
Justin Webb, an associate professor of physical activity and health at London Metropolitan University, said it was "somewhat concerning that 1.1 million people who have never smoked reported using an e-cigarette." He added: "Vapes can help adults stop smoking, but they are not risk-free and their full long-term effects remain unclear. We need to preserve their value as a quitting aid while strengthening protection against uptake among children and non-smokers."
Separate ONS figures covering all four nations of the UK showed that about 4.9 million people aged 18 and over (9.8% of the population) smoked cigarettes in 2025, a decrease from 10.6% in 2024, continuing a long-term downward trend. David Mais, from the ONS, said: "Fewer than one in 10 adults now smoke. This is the lowest proportion on record and continues the long-term decline in smoking."
