Vape Tax Countdown: What Changes on 1 October and What to Do Before It

The Vaping Products Duty starts on 1st October 2026. From that day, every millilitre  (ml) of e-liquid produced for or imported into the UK carries 22p of duty, with VAT on top.

This page outlines the countdown: what happens on the day, what happens gradually, and what is worth doing in the weeks left. For the full explanation of the tax itself, from the mixing rules to the traveller's allowance, our UK vape tax guide covers every rate, rule and exemption.

What changes on 1 October

• The duty begins: 22p per millilitre on all e-liquid, which is £2.64 per 10ml once VAT is added to the duty. 0mg liquid is affected too
• Tobacco duty rises the same day: the price gap between vaping and smoking is kept on purpose
• The 50ml traveller's allowance starts: you can bring up to 50ml of e-liquid into the UK without paying UK duty on it
• Duty stamps appear: newly produced stock starts carrying the stamp, a physical security mark with a digital element for traceability

What does not change overnight

Prices, mostly. Shops are allowed to sell stock bought before October at pre-duty prices until 31st March 2027, so the shelves will not reprice at midnight.

What you will see instead is a slow step up through the autumn and winter as pre-duty stock runs out. This will happen fastest on the popular lines. Buying through the autumn becomes a quiet race between you and everyone else who vapes your flavour.

The countdown calendar

When	What it means for you
Now to 30 September	The last window where everything on sale is at pre-duty prices
1 October 2026	The duty begins; new stock carries it from day one
October 2026 to 31 March 2027	Mixed shelves: pre-duty stock at old prices next to duty-paid stock at the new prices, thinning out as the months pass
1 April 2027	Duty stamps become mandatory; unstamped e-liquid becomes illegal to sell

Five things worth doing before October

1. Work out what you actually get through

Everything else follows from this number. We measured it across almost 18,000 of our own customers: the typical vaper uses 5.7 to 10.3ml a day, prefilled pod users far less, open-system vapers far more. Buy against your real number, in months rather than years.

2. Stock up on what you know you vape

Buying before 1 October is legal, sensible within shelf life, and worth the most on big bottles: every 100ml shortfill bought before the duty saves £26.40 of duty and VAT. Stored cool, dark, sealed and upright, e-liquid keeps well for over a year. A bottle-a-week vaper who buys three months ahead keeps about £34 of duty in their pocket.

3. If you get through a lot of liquid, look at your kit

The duty is charged per millilitre, so it punishes volume. A low-power pod kit on nic salts uses a fraction of the liquid of a sub-ohm setup for the same satisfaction, which shrinks the tax by the same fraction. Switching before October means you're settled into the change before the prices move.

4. Do not assume 0mg escapes it

The rate is flat, with or without nicotine, so zero nicotine liquid and nicotine free vapes pay the same 22p per millilitre. If you vape at zero, every line of this page applies to you too.

5. Learn to spot legal stock now

From 1 April 2027, no duty stamp on the box means illegal stock, and between now and then the clearest warning sign is a price the duty makes impossible. Our duty stamps guide explains how the stamp system works and how to check what you are buying.

Work out your own number

The maths is different for every basket, so our vape tax calculator does it for exactly what you buy, and shows the lowest a bottle can legally be sold for once the duty is in force.

From October, the main vape tax guide carries the whole story, updated as HMRC publishes more.

Vaping is substantially less harmful than smoking but it is not risk-free, and it is intended for adult smokers and existing vapers. If you do not smoke, do not vape.
