Pre-Duty Vapes: Which Products the UK Vape Tax Hits Hardest

From 1 October 2026 every millilitre of vaping liquid sold in the UK carries a new excise duty. Most coverage has focused on how much more a vape will cost. The more useful question is which products get hit, because the answer is wildly uneven — and it is already changing what manufacturers put on shelves.

The rate, and the mistake almost everyone is making

Vaping Products Duty is £2.20 per 10ml. One flat rate, charged on liquid volume, regardless of how much nicotine is in it.

That last part matters, and it is where a lot of articles are wrong. The original 2024 proposal had three tiers — £1.00 per 10ml for nicotine-free, £2.00 for low strength, £3.00 for high. That tiered system was scrapped and replaced with the single flat rate. Plenty of guides still quote the old numbers.

The practical consequence: a 0mg shortfill is taxed at exactly the same rate per millilitre as a 20mg nic salt. Nicotine strength is irrelevant. Volume is everything.

What it does to each format

Because the duty is charged per millilitre, the products holding the most liquid take the biggest hit. Figures below use our current prices, with duty added before VAT and VAT then applied to the total, which is how it will actually be charged.

Read the bottom row again. A 100ml shortfill carries £22 of duty on its own, before the nic shots and before VAT. The format that has been the cheapest way to vape in this country for a decade becomes the most expensive bottle on the shelf almost overnight.

Meanwhile a prefilled pod holding 2ml of liquid carries 44p. Proportionally, small formats barely notice.

Why this is a product strategy change, not a price rise

Manufacturers worked this out well before consumers did, and the response is already visible in what is being launched.

Smaller pods, deliberately

The clearest example is sitting on our shelves. IVG’s Pro range has always been a 2ml + 10ml system. This year they added a 2ml + 4ml version, the Pro 5K. Half the liquid, a lower price per purchase, and IVG’s own trade materials say plainly that it exists to give Pro users a cheaper option once the tax arrives.

Expect more of this. A 6ml pod carries £1.32 of duty; a 12ml pod carries £2.64. Shrinking the pod is the simplest way to keep a shelf price under a psychological threshold.

Bottles getting smaller, not bigger

The industry spent years pushing customers towards large-format shortfills because they were cheaper per millilitre. The duty inverts that logic completely. A 10ml bottle of nic salt carries £2.20 in duty; ten of them carry £22, the same as one 100ml shortfill — but you buy them one at a time, so the shelf price never looks alarming.

We expect brands that walked away from 10ml formats to quietly reintroduce them, and shortfill ranges to narrow to the best sellers.

Concentrates and longfills

The third response is to sell less taxed liquid in the first place: flavour concentrates and longfills, where the customer tops the bottle up themselves. It is more effort and will not suit everyone, but for high-volume vapers the maths becomes hard to ignore.

What happens to stock already on shelves

This is the part almost nobody is reporting correctly, and it matters if you are deciding when to buy.

The duty applies to products manufactured or imported from 1 October 2026. Stock that retailers and wholesalers already hold can be sold without a duty stamp for a further six months, until 31 March 2027. From 1 April 2027 every vaping product sold in the UK must carry a valid duty stamp.

So prices will not jump on 1 October. They will move product by product, as pre-duty stock sells through and duty-paid stock replaces it. Some lines change in October. Others hold into next year.

Where we stand

We are being straightforward about this because you will work it out anyway.

Most of what we are selling right now is pre-duty stock, bought before the change and priced accordingly. While it lasts, you are paying pre-duty prices. When it is replaced with duty-paid stock, the prices in the table above are roughly where things land.

A few lines are already duty-paid and priced for it, including the IVG Pro 5K refills and the 5K kit. Those will not move again. It is also why the 5K currently looks dearer per millilitre than the 10K sitting next to it: one has the tax in it and the other does not yet.

What we would actually do

• If you vape shortfills, this is the format that changes most. Worth trying a 10ml nic salt or a pod system now, while you can still compare properly.
• If you use a pod system, you are among the least affected. Smaller pods carry less duty, so 6ml formats become better value than they look today.
• If you are stocking up, buy what you already know you like. A year of an untried flavour is a false economy.
• Do not panic buy in September. The grace period runs to 31 March 2027. There is more time than the headlines suggest.

The numbers behind this

Rate and dates are from HMRC’s published guidance on Vaping Products Duty and the Vaping Duty Stamps Scheme. Duty figures are calculated at £2.20 per 10ml of liquid, added before VAT, with VAT at 20% applied to the total. Prices are ours at the time of writing and will change as stock turns over.

For the underlying rates and dates, see our guide to the UK vape tax. For bottle prices specifically, read will e-liquid prices rise in October 2026.

Vaping products are for over-18s only and contain nicotine, which is addictive. They are intended as an alternative for existing smokers and vapers, not for non-smokers.
