What Is The MHRA And Its Role In Vaping
What Is the MHRA
and What Role It
Plays in Vaping
The MHRA is the UK’s medicines and medical device regulator. Since 2016 it has also been the central regulator for vape products. Notification, emissions review, safety alerts plus adverse event reporting all run through this one agency.
The MHRA stands for Medicines and Healthcare products Regulatory Agency. It is an executive agency of the Department of Health and Social Care. It regulates medicines, medical devices, blood products plus since 2016, e-cigarettes and refill containers. For UK vaping, the MHRA handles five roles: administering the six-month product notification process, reviewing emissions and ingredient data, running the Yellow Card Scheme for adverse event reports, issuing safety alerts and recalls, plus publishing guidance for producers and retailers. The MHRA is the single UK body that decides whether a vape product can legally reach the market.

The MHRA runs five distinct functions for UK vaping
The MHRA is a familiar name for medicines regulation. Its vape role is less well understood by consumers but it is the single most important agency in the UK vape market. Five functions run in parallel. Together they set the floor for legal vape access in the UK.
Function 1: product notification
Every vape SKU sold in the UK must be notified to the MHRA at least six months before sale. The producer submits a full specification covering:
- Ingredient list by CAS number for every e-liquid component.
- Emissions test data from a UKAS-accredited laboratory.
- Stability testing under accelerated ageing conditions.
- Device specification including battery, tank, coil plus refilling mechanism.
- Packaging artwork showing labelling plus health warnings.
Function 2: emissions and ingredient review
During the six-month window the MHRA reviews the submitted data. Checks include:
- No banned substances listed in Schedule 1 of the TPD.
- Emissions within normal parameters for nicotine, heavy metals plus regulated compounds.
- Ingredient disclosure complete with valid CAS numbers.
- Device specification within TPD limits including the 2ml tank plus 20mg/ml nicotine ceiling.
Function 3: Yellow Card Scheme
The Yellow Card Scheme is the MHRA adverse event reporting system. It originally covered medicines and medical devices. It was extended to e-cigarettes in 2016. Key features:
- Online submission at yellowcard.mhra.gov.uk. No account required for consumer reports.
- Consumer or clinician reporter. Anyone can submit.
- Covers product faults plus health effects. Includes suspected battery failures, burns, allergic reactions plus other adverse events.
- Signal detection. Multiple reports on the same product trigger MHRA review.
- Can lead to safety alerts or recalls depending on the findings.
Function 4: safety alerts and recalls
When a safety issue emerges the MHRA can order a recall plus publish a public safety alert. The process:
- Safety alert published at gov.uk naming the affected product.
- Notification suspended or removed from the MHRA database.
- Retailers withdraw stock within 28 days.
- Consumers offered refunds under the Consumer Rights Act 2015.
- Follow-up investigation determines whether the issue was batch-specific or systematic.
Function 5: guidance and industry support
The MHRA publishes extensive guidance documents for producers plus retailers. Key outputs:
- E-cigarette notification guidance covering every field of the submission form.
- Emissions testing guidance on acceptable methods plus laboratories.
- Annual reporting guidance for producers on post-market obligations.
- Industry consultation responses on policy changes such as the disposable ban plus the 2026 vape duty.
- Stakeholder engagement with the UK Vaping Industry Association plus consumer groups.
