Most e-liquids are made from four kinds of ingredient. Here is what each one does, and the rules a nicotine e-liquid has to meet before it can be sold in the UK.
The ingredients
- Propylene glycol (PG): a thin liquid that carries flavour well and gives more throat feel.
- Vegetable glycerine (VG): a thicker, slightly sweet liquid that produces more vapour.
- Flavourings: blended to create each flavour, from AISU Aloe Vera to ZAP! Juice Melonade.
- Nicotine: either freebase nicotine or nicotine salt. Nicotine-free liquids, such as our 50ml 0mg shortfills, contain none.
The VG/PG ratio is printed on every bottle. Our nic salts and bar salts contain nicotine (5mg/ml to 20mg/ml) and are 50VG/50PG; our 0mg shortfills are 70VG/30PG. Our guide to nicotine e-liquids vs nic salts explains the difference between the two types of nicotine.
UK rules for nicotine e-liquid
Under the Tobacco and Related Products Regulations 2016, nicotine e-liquid sold in the UK must:
- come in refill bottles of no more than 10ml
- contain no more than 20mg/ml of nicotine
- use child-resistant, tamper-evident packaging
- carry the required nicotine warning and an ingredients list
- leave out certain additives, including colourings, caffeine and taurine
- be notified to the MHRA before it goes on sale.
The UK vaping duty
From 1 October 2026, e-liquid sold in the UK carries Vaping Products Duty, including nicotine-free liquid. Duty stamps are also being introduced for vaping products; GOV.UK has the dates.
