The three dates that matter

This is not a gradual change like tobacco duty. It arrives in one step, with a fixed window afterwards. Three dates decide everything.

What the duty actually is

The Vaping Products Duty is charged on the volume of liquid, not the device and not the nicotine strength. It is a flat 22p per millilitre. VAT at 20% is then charged on top of the duty, so the real amount added is 26.4p per ml. A 0mg shortfill is taxed exactly the same as a 20mg nic salt.

Which products the vape tax applies to

The duty follows the liquid, not the format. Nicotine strength makes no difference, and 0mg is taxed exactly the same. Every one of these is charged on the millilitres it holds:

Bottled e-liquid

Shortfills, nic salts, longfills, freebase e-liquid, 50/50 juice and high VG. A 100ml shortfill is taxed on the full 100ml before you even add your nicotine.

Prefilled pod kits and big-puff disposables

The liquid sealed inside the device is taxed, so prefilled pod kits and big-puff refill kits all carry the duty on their ml.

Prefilled pods and refill pods

Prefilled and refill pods are taxed on the total liquid across the pack. UK pods hold up to 2ml each, so a pack adds up.

Nic shots and 0mg

A 10ml nic shot is 10ml of taxable liquid, and nicotine-free shortfills are taxed the same because the charge is on volume, not nicotine. This is one of the new vape laws arriving in 2026, and it is why the tax on vapes will lift prices across the whole liquid range, not just bottles.

What it adds to each type of product

Because the tax follows the millilitres, the impact is very different across the range. A single 2ml pod barely moves. A 100ml or 200ml shortfill takes the biggest hit, because you are taxed on the full bottle even before you add your nicotine. That is the part worth planning around.

Shop the ranges this affects: shortfill e-liquids, nic salt e-liquids, prefilled pod kits and replacement pods.

What it adds to your monthly spend

The clearer way to picture it is by how much you actually vape. At 26.4p per ml, the added duty depends entirely on your daily use. Here is the extra cost per month at a few common levels.

None of these figures are the shelf price. They are only the tax added on top. Retailers still set their own margins and deals, but the duty sets the floor that no compliant seller can go below. For a fuller breakdown of how much e-liquid is going up and when, read our companion guide.

What other countries already show us

The UK is not doing anything unusual here. A per-millilitre duty on e-liquid, charged the same whatever the nicotine strength, is the way the rest of Europe is already going. The closest example is Ireland. On 1 November 2025 it brought in an E-liquid Products Tax at a flat 50 cent per millilitre on every e-liquid, nicotine or not. On the day it landed, the cheapest 10ml bottles roughly doubled in price, moving from around 4 euro to closer to 10. Germany already taxes e-liquid too, at about 26 cent per ml in 2025, rising to about 32 cent per ml in 2026.

Seen against that, the UK's 22p per ml sits at the lower end, but the effect is the same everywhere: the cheapest liquid rises the most in percentage terms. Ireland is the clearest preview of what 1 October 2026 looks like here, and it is exactly why the pre-duty window before then is worth using. You can read the full UK detail in HMRC's Vaping Products Duty guidance.

The duty stamp: how to spot legit stock

From 1 October 2026, duty-paid e-liquids and prefilled pods carry a physical vaping duty stamp on the retail packaging (the UK duty stamps scheme). It is the simplest way to check a product has been taxed and sold legally. As prices rise, cheap unstamped liquid will appear, and it is worth being cautious of it. Product that is priced well below the duty floor may be non-duty-paid, smuggled, or non-compliant with UK safety standards. Buying from an established UK retailer is the safe route through the change.

Why the same e-liquid may show two prices

Between 1 October 2026 and 31 March 2027 there is a crossover. Shops are allowed to sell older, pre-duty stock at the same time as new, duty-paid stock. So for a while the same product, even the same flavour, can appear at two different prices depending on which batch it came from.

It is not a pricing trick. Faster-selling flavours get restocked sooner, so they pick up the duty first, while slower sellers can stay on pre-duty stock for longer. During the window it is worth checking whether a bottle is pre-duty or already duty-paid rather than assuming a like-for-like price. From 1 April 2027 the gap closes for good, because everything on sale has to be duty-paid and stamped.

How to spot stock that has not paid the duty

Once the duty is fully in force from 1 April 2027, price itself becomes a useful warning sign. Every legal product has to carry the duty, and the duty alone sets a hard floor that no compliant seller can go under. If something is priced below the tax it should already contain, it has almost certainly not been duty-paid, which can mean smuggled, counterfeit, or outside UK safety rules.

The duty stamp on the packaging is the reliable check. If it is missing after 1 April 2027, the product should not be on sale. Buying from an established UK retailer like Ecigone is the safe route through the change.

Why the government is introducing it

HMRC gives two reasons: to reduce youth uptake of vaping by removing the low price advantage, and to bring vaping closer in line with how tobacco is taxed. Vaping still comes out considerably cheaper than smoking even after the duty, but the gap at the till narrows, especially for heavier users.
