Simple maths shows that HMRC’s figures cannot possibly be accurate. Converting kilograms of rolling tobacco into sticks, the equivalent of 36.6 billion cigarettes were sold legally in the UK in 2022. If this declined at the same rate as smoking prevalence (-17 per cent), it would have been 30.4 billion by 2024. In fact, there were only 22.9 billion cigarettes sold legally in 2024, a shortfall of 7.5 billion.
If we imagine, for the sake of argument, that there was no illicit tobacco at all in 2022, this would mean that 25 per cent of the total market was illicit by 2024/25 (7.5 billion is 25 per cent of 30.4 billion). If you believe, as HMRC does, that 13 per cent of the market was illicit in 2022/23, it means that 33 per cent of the market was illicit in 2024/25. If HMRC underestimated the size of the black market in 2022/23, the real figure is higher still, but the absolute minimum it could be in a wildly optimistic and frankly impossible scenario is 25 per cent.
The only piece of solid data is the legal sales figure. We have survey data for the number of smokers and the number of cigarettes they consume, but the ONS survey HMRC relies on had its status as an official accredited statistic withdrawn in 2024 due to “ongoing challenges with the response rates, levels, and weighting approach”. Moreover, smoking prevalence and cigarette consumption figures always need to be adjusted upwards to account for shy smokers and under-reporting. This requires a certain amount of guesswork. Estimates of how much duty-free tobacco is brought into the UK are also based on surveys and may be inaccurate.
A further problem is that during the pandemic, the ONS stopped asking people how much they smoked. HMRC therefore “imputed” the figures for 2020/21, 2021/22 and 2022/23. The question was asked again in 2023/24 and so HMRC describes its estimate for that year as “actual”, but it has gone back to guessing for 2024/25. Blaming “modifications to question sequencing and funding limitations” it says that “certain consumption data for 2024 to 2025 are incomplete”. It has therefore “projected consumption data” for 2024/25 “based on established historical trends.” But what we are seeing today is not in line with historical trends. That is the whole point!
The best way to gauge the size of the black market in tobacco is to gather a large and representative sample of disused tobacco packs and see whether they were sold legally. Tobacco companies have been doing this for years. KMPG, acting on behalf of Philip Morris International (PMI), produce an annual empty pack survey which recently found that 33 per cent of cigarette packs in the UK were contraband or counterfeit. Japan Tobacco International (JTI) use a slightly different methodology in which they interview smokers in their homes and offer to exchange their empty or current pack of cigarettes for a JTI brand. Using this system, they estimate that 33% of cigarettes and 50 per cent of hand-rolling tobacco were illicit in 2024/25 (their figures for 2025/26 suggest that this has risen to 42 per cent and 60 per cent respectively).
Many people are wary of claims made by tobacco companies, but the Irish government has been using a close cousin of the JTI survey since 2009 for its official estimates. With a similarly high level of tobacco duty, the official Irish figures are similar to the industry’s figures for the UK. Ireland’s 2025 survey found that 28 per cent of cigarettes and 37 per cent of hand-rolling tobacco was illicit.
