Longfills and the 2026 Vape Tax: What It Means for Vapers
Longfills and
the 2026 vape tax:
what it means for you
A plain-English UK guide to the Vaping Products Duty going live on 1 October 2026. What the £2.20 per 10ml rate actually means for your longfill bottles, when the changes hit the shelf plus the practical steps to take before October.
From 1 October 2026 every 10ml of vape liquid sold in the UK carries a new duty of £2.20 plus 20 percent VAT on top (£2.64 effective). This applies to longfill concentrate plus Mixer Kit nic shots equally. A 60ml finished longfill adds roughly £15.84 in duty plus VAT to its current retail price. Buying bottles before October 2026 locks in pre-duty prices for concentrate that stores well for twelve months or more in a cool dark cupboard.
Three numbers
that drive the change
The duty rate, the applicable date plus the volume it covers. Three numbers that define the new UK vape economics.
Duty per ml
Flat rate on every ml of vape liquid. Equivalent to £2.20 per 10ml regardless of nicotine strength.
Total per 10ml with VAT
The effective duty impact on a retail shelf once the standard 20 percent VAT is added on top.
Longfill bottle size
A standard finished longfill attracts six units of duty. £13.20 direct plus £2.64 VAT = £15.84 total impact.
The Vaping Products Duty is a new UK excise tax on all e-liquid. Here is how it works.
The Vaping Products Duty was confirmed as part of the Spring Budget 2024 plus legislated through the Finance Bill 2025-26. It is a brand new UK excise duty that did not exist before. Up to now UK vape liquid has been subject only to standard 20 percent VAT. From October 2026 it carries a dedicated excise charge similar in spirit (though not in scale) to tobacco or alcohol duty.
The rate settled on is a flat £2.20 per 10ml of vape liquid, equivalent to 22p per ml. This applies regardless of nicotine strength. Nicotine-free shortfills pay the same per-ml duty as high-strength nic salts. The flat rate replaced an earlier proposal for a tiered structure that would have taxed stronger liquids more heavily. The tiered approach was dropped after consultation feedback, mostly because it was seen as harder to administer.
The duty applies to any liquid intended to be vapourised including e-liquid bottles, shortfills, longfill concentrate, nic shots, prefilled pods plus similar formats. It does not apply to hardware (devices, batteries, refillable pods). It also does not apply to medical nicotine products like patches or gum. Nor does it apply to anything outside the vaping category.
How this specifically affects longfill users
A longfill format is two components by design. The 60ml bottle contains 30ml of concentrate which is subject to duty as vape liquid. The three 10ml nic shots in a Mixer Kit are also subject to duty as vape liquid. Both parts pay the same per-ml rate. Total duty on a finished 60ml longfill: 60ml x 22p = £13.20 of direct duty, plus 20 percent VAT of £2.64, for a total additional cost of £15.84 compared with today’s pre-duty prices.
This is the same total duty impact as any other 60ml of finished e-liquid regardless of how it was packaged originally. The tax is purely volume-based. What differs across formats is the starting pre-duty price. A longfill format starts cheaper than shortfills per ml, so while both incur the same duty, the longfill format ends up lower on the shelf even post-October.
- Duty on concentrate. 30ml x 22p = £6.60 per longfill bottle.
- Duty on Mixer Kit. 3 x 10ml x 22p = £6.60 per kit.
- Plus 20 percent VAT. On the duty itself, adding a further £2.64 per 60ml.
- Total added cost. Roughly £15.84 per finished longfill bottle.
Four dates
longfill users should know
The Vaping Products Duty rollout happens across four key dates. Plan around them to avoid mis-timed purchases.
Registration to enforcement
Each date changes what is legal to buy or sell in the UK vaping market. The furthest right date (April 2027) is the one that ends the grace period completely.
The duty calculation
for any bottle
The maths is simple enough to do in your head. Here is the formula plus three worked examples across common UK product sizes.
Duty formula per bottle
Multiply total ml of vape liquid by 22p to get the duty. Add 20 percent VAT to get the shelf impact.
60ml Longfill + Mixer Kit
50ml Shortfill + 1 nic shot
Ten 10ml bottles
Four practical steps
before October 2026
Concrete actions UK longfill users can take between now and the duty start date. The earlier the better.
Stock up on concentrate
Unmixed longfill concentrate stores well in a cool dark cupboard for twelve months or more. Buy your favourite flavours now before duty hits. Keep bottles sealed, out of sunlight plus below 25°C.
Buy Mixer Kits too
Nic shots inside Mixer Kits keep for roughly the same period as concentrate when stored correctly. Match the number of Mixer Kits to the number of longfill bottles you stock so you are ready to mix when needed.
Review your strength choice
With bottles costing more per ml after duty, picking the right strength first time matters. If your current nicotine level is too high or too low, dial it in now so you do not waste post-duty bottles on experiments.
Check for duty stamps
From October every legal retail bottle carries a Vaping Duty Stamp. If you see products without stamps after April 2027 they are illegal. Stick with reputable UK retailers to avoid black-market imports of dubious quality.
Stock up on Nixer
before October 2026
