Could The Vape Tax Push People Back To Smoking
Could the Vape Tax
Push People Back
to Smoking?
The debate behind the 2026 UK vape excise duty. How the proposed rates compare to tobacco duty, what evidence from Italy and Germany shows plus which vapers are most at risk of relapsing.
For most adult ex-smokers the honest answer is no. Even after the UK vape excise duty starts on 1 October 2026 a typical week of vaping remains well under half the cost of a week of smoking because tobacco duty continues to make cigarettes the most expensive nicotine product on the UK market. The risk sits at the margin. Heavy daily vapers on a very tight budget are the group public health bodies are watching most closely. Evidence from Italy and Germany where similar vape duties already exist shows a small impact on occasional users plus almost none on former smokers.
Three numbers that shape
the relapse debate
The relapse question is really a price question. These three figures show how the proposed vape duty lands against cigarette prices in April 2026.
Typical 20-pack cigarettes
The April 2026 retail price of a mid-market 20-pack of cigarettes in the UK after tobacco duty plus VAT.
Proposed vape duty rate
The indicative 2026 duty per 10ml of e-liquid based on the HMRC consultation response. Subject to final legislation.
Post-duty vaping cost
Estimated daily cost of moderate nic salt vaping after the 2026 duty applies. Still a fraction of the smoking equivalent.
Whether a vape tax pushes people back to smoking depends on four things
The headline concern around the 2026 UK vape excise duty is easy to state. If vaping becomes more expensive will some ex-smokers work out that a 20-pack of cigarettes is better value and switch back? The honest answer depends on four variables. Get any one of them wrong and the argument falls apart in either direction.
Variable 1: how big the price gap remains
This is the single biggest factor. A vape tax only risks pushing people back to smoking if it narrows the price gap between vaping and smoking to the point where cigarettes become the cheaper option. At the rates HMRC has floated the gap stays wide. A 20-pack of mid-market cigarettes costs around £16 in April 2026. A day of moderate nic salt vaping at post-duty prices sits close to £3. That is a five to one ratio in favour of vaping. A heavy daily user on shortfills sees a smaller gap but vaping still wins on cost.
Variable 2: which user group we are talking about
Aggregate numbers hide important differences. The population that public health experts watch most carefully are:
- Heavy daily vapers on tight budgets. Typically getting through 30ml or more of e-liquid a week. The extra duty bites hardest here.
- Recent ex-smokers. Less than 12 months into their switch. Still within the window where cigarette cravings can return.
- Occasional social vapers. Not dependent on nicotine. Least likely to relapse because they were not smokers to begin with.
- Ex-smokers of several years. Established in a vape routine. Very low relapse risk regardless of duty.
The relapse risk is concentrated in the first two groups. The Treasury consultation explicitly asked what mitigations might protect these users. Options discussed included a stepped duty over three years plus a lower rate for nic salts versus shortfills.
Variable 3: what the international evidence shows
The UK is not the first European country to tax vape liquid. Italy introduced a vape duty in 2014 plus increased it several times since. Germany introduced its own duty in 2022. Both markets have been tracked closely by public health researchers. The headline findings are:
- Small price rises shifted behaviour within the vape market not out of it. Buyers moved to cheaper brands or larger bottles.
- Smoking prevalence did not rise in either country after duty was introduced. Both tracked ongoing declines in adult smoking.
- Cross-border and informal market activity did increase. Both Italy and Germany saw a rise in non-duty-paid e-liquid.
Variable 4: how the duty is rolled out
A duty introduced overnight at a punitive rate produces a very different outcome to a stepped rollout at a modest rate. The UK approach set out in the 2025 consultation response is closer to the latter. A single flat rate at a moderate level with a short transition window for retailers to sell through existing stock.
Four vaper profiles and
how the duty affects each
Recent ex-smoker
Within 12 months of switching. Highest relapse risk profile. Public health advice is to switch to a cheaper option within vaping rather than back to cigarettes.
Long-term ex-smoker
More than 18 months into vaping. Very low relapse risk. Likely to simply absorb the price rise or move to longfill or shortfill formats.
Heavy daily user
30ml+ of e-liquid a week. Biggest absolute duty bill. Best savings come from switching from nic salts to shortfills or longfills.
Occasional social vaper
Uses a vape a few times a month. Very low relapse risk because they were not a smoker before. Duty impact is negligible in real money.
A week of smoking vs
a week of vaping after duty
Plain English cost picture for a 20-a-day smoker versus an equivalent daily vaper. Figures are April 2026 retail prices plus the proposed October 2026 duty.
A week of a 20-a-day habit
- ✗7 packs at £16 equals £112 per week in cigarettes alone.
- ✗Tobacco duty included at £7.49 per 20-pack excise plus VAT on the duty.
- ✗Annualised cost of a 20-a-day habit sits close to £5,800.
- ✗Health costs not factored in. NHS estimates smoking costs the UK £17bn a year.
- ✗Additional smoke-related costs such as lighters, higher life insurance plus deep cleaning.
A week of equivalent vaping
- ✓7 x 10ml nic salts post-duty equals around £43 per week for an equivalent nicotine hit.
- ✓Vape duty included at £2.20 per 10ml plus VAT on the duty.
- ✓Annualised cost around £2,250 plus occasional pod or coil replacement.
- ✓Savings of roughly £3,550 a year versus smoking even after the new duty.
- ✓Cheaper formats exist. Switching to a 100ml shortfill or longfill cuts weekly spend by half again.
