Smoking has fallen from 20.2% of adults in 2011 to 9.8% in 2025, a drop of more than half. The fall has been steepest among the young. The gap between the least and most qualified has not closed.
The Office for National Statistics (ONS) estimates that 9.8% of UK adults aged 18 and over smoked in 2025, about 4.9 million people. In 2011 the figure was 20.2%, so prevalence fell by 10.4 percentage points and is now 48.5% of its 2011 level.1 Men (11.3%) were more likely to smoke than women (8.2%). By nation, the rate was 9.5% in England, 9.9% in Northern Ireland, 11.1% in Wales and 11.4% in Scotland.1
The fall is largest among the youngest adults. Among 18 to 24 year olds it went from 25.7% to 7.2%, a drop of 18.5 points, which leaves that group tied with the over-65s as the lowest of any age band. The highest rate is now in the 45 to 54 band, at 12.4%.1
Among adults with no qualifications, 24.8% smoked in 2025. For those with GCSE grades A* to C or equivalent the figure was 14.9%, and for those with a degree or equivalent it was 4.7%. The highest to lowest ratio is 5.3 to 1, a gap of 20.1 points.1 Work status shows a similar split: 16.5% of unemployed adults smoked, against 11.1% of economically inactive adults and 8.7% of those in paid employment.1
A separate ONS survey, the Opinions and Lifestyle Survey, covers Great Britain and people aged 16 and over. It puts current smoking at 8.7% in 2025, against 9.1% in 2024, and daily or occasional e-cigarette use at 9.9%, essentially unchanged from 10.0%. The ONS says this survey is not its official smoking estimate.1 Among 25 to 34 year olds, vaping rose from 8.6% in 2020 to 12.9% in 2024 and 16.4% in 2025. About 2.9% of people who have never smoked vape, around 1.1 million people.1
The bulletin text gives 2011, 2024 and 2025 for all adults, so the path in between, and whether the latest 0.8-point fall (10.6% to 9.8%) is larger than survey error, is not shown here. It does not give qualification or work-status rates for earlier years. The vaping figures come from a different survey, with a different population, so they cannot be netted against the smoking figures, and nothing here shows whether anyone swapped one for the other.
