UK Vaping Laws and E-Liquid Regulations Explained (2026)

21st Jun 2023

Overview of UK vaping laws and regulations, covering TRPR requirements, age restrictions, product standards, MHRA notification and recent regulatory changes.

UK vaping law covers a lot of ground: what's in the bottle, how it's packaged, who can buy it, and what's changed most recently around disposables and tax.

This guide covers the core rules that apply to every product on sale here, plus the recent changes worth knowing about, with links to our full guides on each.

Vaping products are for adult smokers and existing vapers only. Vaping is not risk-free. Not suitable for non-smokers or anyone under 18.

UK Vaping Laws at a Glance

  • Maximum nicotine strength: 20mg/ml.
  • Maximum sizes: 10ml for a bottle of nicotine e-liquid, 2ml for a tank or pod.
  • Minimum age to buy: 18
  • Single-use disposable vapes: banned from sale since 1 June 2025.
  • Vaping Products Duty: £2.20 per 10ml of e-liquid from 1 October 2026.
  • Duty stamps: required on every vaping product sold from 1 April 2027.
  • Generational tobacco ban: from 1 January 2027, tobacco can't be sold to anyone born on or after 1 January 2009. This covers tobacco, not vapes.

The Law Behind UK Vaping Products: TRPR, Not TPD

Most of the rules that shape a UK vape today come from the Tobacco and Related Products Regulations 2016 (TRPR). TRPR is UK law, not EU law: it was originally introduced to implement the EU's Tobacco Products Directive (TPD) while the UK was still a member state, but since Brexit it stands as retained UK legislation in its own right, enforced by the Medicines and Healthcare products Regulatory Agency (MHRA) rather than any EU body.

The UK hasn't simply carried on following EU rules by convention; TRPR is domestic law that the UK government can and does amend independently, which is exactly what's happened with the more recent changes covered below.

UK E-Liquid Rules: Strength, Bottle Size and Labelling

  • Nicotine strength: capped at 20mg/ml. No nicotine-containing e-liquid sold in the UK can legally exceed this, regardless of brand or format.
  • Bottle and tank size: limited to 10ml for nicotine-containing e-liquid bottles and 2ml for tank or pod capacity.
  • Packaging and labelling: nicotine-containing e-liquid must come in child-resistant, tamper-evident packaging. The label has to list the ingredients and nicotine content, carry a batch number, and show the health warning "This product contains nicotine which is a highly addictive substance" covering 30% of the pack. A leaflet with instructions for use and safety information must be included as well.
  • Product notification: every vaping product sold in the UK must be registered with the MHRA before sale, going through emissions and toxicity testing first. You can check the MHRA's public register to confirm a product is properly notified.
  • Age restriction: it's illegal to sell any vaping product to anyone under 18, and retailers are expected to challenge anyone who appears under 25.

These rules apply equally to every retailer and every brand sold in the UK, V2 UK included.

What's Changed Recently

Three significant changes have landed on top of the core TRPR framework in the last two years:

The disposable vape ban. Single-use disposable vapes have been illegal to sell or supply since 1 June 2025. Rechargeable devices, whether refillable or using replaceable pods, remain completely unaffected. Our full guide to what's still legal after the disposable ban covers this in detail.

The Tobacco and Vapes Act 2026. This received Royal Assent on 29 April 2026. Its best-known measure is a rolling “smokefree generation” policy, meaning nobody born on or after 1 January 2009 will ever legally be sold tobacco products in the UK. It also gives government new powers over vape packaging, flavour naming, advertising and retail licensing, some of which are still being consulted on rather than finalised.

The Vaping Products Duty. From 1 October 2026, a flat duty of £2.20 per 10ml applies to all e-liquid, regardless of nicotine strength. Our UK Vape Tax 2026 guide covers what that means for what you buy, and our report from inside the industry's UKVIA Forum covers the case being made against the rate itself.

What's Coming Next

More changes are already set or planned under the Tobacco and Vapes Act 2026 and the new duty:

  • 29 October 2026: it becomes illegal to sell any vaping or nicotine product to under-18s, including nicotine-free vapes, and free samples or giveaways of vaping products are banned.
  • 1 January 2027: the generational tobacco ban begins. It covers tobacco products, not vapes.
  • 1 April 2027: every vaping product sold in the UK must carry a valid vaping duty stamp.
  • Planned for 2027 and beyond: a ban on vape advertising and sponsorship, a licensing scheme for retailers, product registration, and possible rules on flavours, packaging and in-store display. These depend on regulations and consultations that haven't been finalised yet.

We'll update this guide as each change comes into force.

Why Buying From a Regulated UK Retailer Matters

Every product sold by a properly regulated UK retailer has been through MHRA notification, meaning it's had emissions and toxicity testing before it ever reached a shelf. Unregulated or illicit vapes, sold without going through this process, carry a higher risk: there's no guarantee of what's actually in them, no verified nicotine strength, and no safety testing behind the claims on the packaging.

This isn't a hypothetical concern. New peer-reviewed research from the University of East Anglia, published in the journal Addiction in 2026, looked specifically at how illicit vapes are marketed to young people online, and found sellers using tactics like bundling vapes with cosmetics or sweets to get around age checks, alongside content that normalises illicit vaping as harmless.

If a product is being sold “under the counter,” through social media, or at a price that seems too low to be genuine, that's usually a sign it hasn't gone through the proper regulatory process, and its actual contents can't be verified.

Frequently Asked Questions

Is vaping legal in the UK?

Yes. Vaping is legal for adults in the UK, and you can buy rechargeable and refillable vapes and e-liquid from regulated retailers. Single-use disposable vapes can no longer be sold, and venues, transport operators and employers can set their own rules on where you can vape.

Is TPD still the law in the UK?

Not directly. TPD was the EU directive that originally shaped these rules, but since Brexit the UK has its own retained version, the Tobacco and Related Products Regulations 2016 (TRPR), enforced by the MHRA. The core limits, like the 20mg/ml nicotine cap, haven't changed, but the UK can now amend its own rules independently of the EU, which is exactly what's happened with the disposable ban and the new duty.

What's the maximum nicotine strength I can legally buy?

20mg/ml, under TRPR. This applies to every nicotine-containing e-liquid sold in the UK, regardless of format or brand.

What is the legal age to vape in the UK?

18. It's illegal to sell vaping products to anyone under 18, and from 29 October 2026 that covers nicotine-free vapes too. Retailers are expected to ask anyone who looks under 25 for ID. Our guide to the legal age to vape covers this in more detail.

Can I vape anywhere I like in the UK?

There's no single national law banning vaping in public generally, but individual venues, transport operators and employers can and do set their own rules, often mirroring their smoking policy. Always check signage or ask before assuming it's fine.

How do I know if a vape product is properly regulated?

Check the MHRA's public product register if you're ever unsure, or simply buy from an established UK retailer that can show its products are notified.

About the Author

Joe Delaney, Director and Content Writer at V2 Cigs UKJoe Delaney looks after the day to day running of V2 Cigs UK and writes its blogs.

When the blog recommends a device, he has used it - and for a leak test that means actually filling kits and trying to make them fail, pocket-carrying them and leaving them upside down overnight, rather than repeating manufacturer claims.

Health, safety and regulatory points are checked against named UK authorities such as the NHS and MHRA, and a product is only ever called "less harmful than smoking" where a UK authority says so. More about how he works, and the family story behind V2, is on Joe's author profile.
