Is it Legal to sell and buy caffeine vape liquid in the UK?

In the last decade, the UK vaping market has grown at a rapid pace. As the demand for vaping products grows, more vape shops are springing up on UK high streets.

It's no surprise that as the popularity of electronic cigarettes and e-juice rises, so do regulations on them. The Tobacco Products Directive governs e-cigarettes and refills containers in the United Kingdom (TPD). As of February 2016, the UK Tobacco and Related Products Regulations 2016 put the TPD into effect.

  • E-liquids that contain nicotine cannot be sold in quantities greater than 10ml unless registered as medicine. 
  • E-liquid nicotine strengths cannot exceed 20mg/ml unless registered as a medicine. 
  • E-liquid packaging must be child-resistant and tamper-evident. 
  • E-liquids that contain nicotine cannot contain additives such as colouring, caffeine, or taurine.
  • Medicines and Healthcare Products Regulatory Agency registration is required for all e-cigarettes and e-liquids before they may be sold.
  • Stringent labelling regulations.

So to answer the question about the legality of caffeine vape liquid in the Uk, the answer is yes as long as it does not contain nicotine it is legal to sell and buy e-liquid that contains caffeine. 


Retailers on the high street and online have been warned that failure to comply with the new rules might result in jail time.

Nearly nine in ten of the UK's vape shops are happy to offer electronic cigarettes to nonsmokers, according to undercover research.

One hundred of the 1,700 specialist vape shops in England, Scotland, and Wales were investigated by the Royal Society for Public Health (RSPH), which discovered that 87% were either willingly or naively prepared to sell e-cigarettes to persons who had never smoked or vaped.

According to the RSPH, less than half of the outlets did not ask clients if they had ever smoked previously, and three-quarters of those that did still encouraged non-smokers to start vaping.

British Vape Trade Association chief executive Richard Hyslop remarked that vape products should not be sold to non-smokers or people under the age of eighteen years.

In the UK, over 90% of vapers are current or former smokers, according to organizations like the Office for National Statistics and Ash (Action on Smoking and Health). We thus do not believe that this is a serious problem."

Etiquette experts advise vaping enthusiasts to always ask whether it's okay before puffing away.

So to answer the question about the legality of caffeine vape liquid in the Uk, the answer is yes. Although there are regulations to ensure e-liquids are safe for consumption, there is no ban on them. For your safety, ensure you get your vape products from a licensed vendor.
