The short answer
No single visual clue can prove that a vape is genuine and compliant. A low price, spelling mistake, missing code, or poor print can justify suspicion, but convincing packaging and a code that resolves can also be copied. Check the exact nicotine product on the MHRA published-products list, confirm the design is legal under current UK rules, use only the real manufacturer website for any batch or authenticity check, inspect the seller and product details, and search official recall records.
Stop using a device immediately if it becomes unusually hot, bulges, hisses, leaks, activates by itself, smells unusual, or appears damaged. If it smokes or catches fire, leave the area, call 999, and do not try to tackle the fire. Suspected illegal or counterfeit sales can be reported to Trading Standards; suspected side effects or nicotine e-cigarette safety concerns can be reported through the MHRA Yellow Card scheme.
Key points
- Counterfeit, illicit, non-compliant, recalled, and faulty describe different problems and need different evidence.
- Packaging, price, QR codes, and authenticity codes are clues, not proof on their own.
- A matching MHRA record is necessary for legal supply of a nicotine product but does not authenticate the unit in your hand.
- Battery warning signs outrank every authenticity check: stop using a hot, swollen, hissing, leaking, or damaged device.
- Keep safe evidence and use the correct route for a seller report, product recall, suspected side effect, or recycling.
Fake is often used for every product that looks wrong. That hides important differences. A counterfeit imitates another brand. An illicit product may be genuine but supplied outside UK law. A non-compliant product fails one or more product requirements. A recalled unit has a documented safety action. A faulty device may be authentic and compliant when sold but damaged or defective now.
The response depends on which problem the evidence supports. This guide gives a safe order of checks without promising certainty from a photograph. First understand the single-use vape rules, then use the sub-ohm guide for device and liquid suitability boundaries. If the issue is liquid compatibility rather than authenticity, use the e-liquid format guide.
Name the problem before deciding what the evidence means
| Comparison point | What it means | Useful evidence | Primary response |
|---|---|---|---|
| Counterfeit | A product or pack falsely presents itself as another brand or source | Manufacturer confirmation, batch details, authorised-supply records, packaging comparison | Stop use if safety is uncertain, contact the brand and retailer, report the seller |
| Illicit supply | A product supplied outside applicable UK rules, even if the brand is genuine | Missing MHRA publication, prohibited single-use design, unlawful supply evidence | Do not buy or resell, return if safe, report to Trading Standards |
| Non-compliant | Fails a product, packaging, notification, nicotine, container, or safety requirement | Exact variant data, label, liquid volume, strength, MHRA record, regulator report | Stop supply or use as appropriate and refer the evidence to the regulator |
| Recalled | A specific model or batch is subject to corrective action | OPSS recall or safety notice matched to model and batch | Follow the notice for stopping use, return, replacement, repair, or refund |
| Faulty or damaged | The individual device is malfunctioning or physically unsafe | Heat, swelling, hissing, leakage, auto-activation, damage, unusual odour | Stop using and charging immediately, then follow fire-safe disposal or emergency action |
Important context: A device can fit more than one row. For example, a counterfeit can also be non-compliant and physically faulty. Safety action comes before proving the label.
Why no one-minute visual test is reliable
A box can be copied, a QR code can lead to a cloned site, and a genuine serial can be printed on more than one fake unit. A legitimate discount can look suspicious, while a high price can be attached to counterfeit stock. Spelling, colour, seals, and print quality remain useful comparison points, but they do not reveal the liquid contents or battery construction.
The strongest conclusion comes from independent checks agreeing: the exact product appears on the appropriate MHRA list, the manufacturer confirms the code and batch through a domain you reached independently, the product design and label fit current rules, the seller can provide normal records, no OPSS safety action applies, and the physical unit behaves normally. Even then, a later defect or recall remains possible.

Limitation: The MHRA record covers the notified product identity and legal-supply prerequisite. It does not remotely inspect, test, or authenticate the individual retail unit being checked.
Check a suspected vape in the safest order
Stop if the device shows a physical warning sign
Do not continue testing a device that is unusually hot, swollen, hissing, leaking, damaged, smelling unusual, or firing without a draw or button press. Disconnect power only if that can be done safely.
Record the exact identity without dismantling it
Photograph the front, back, warnings, barcode, batch or lot number, nicotine strength, liquid volume, seller listing, receipt, and any verification result. Do not puncture or open a sealed unit to investigate.
Search the MHRA published-products list
For a nicotine product, match the exact brand, subtype or flavour, product type, and submitter where possible. A related brand result is not the same as the exact variant.
Check the current legal format
Check nicotine concentration and presentation, then apply the reusable-device test. Since 1 June 2025 a business cannot supply a true single-use vape, including a nicotine-free one.
Reach the manufacturer independently
Type or search for the official manufacturer domain rather than trusting a QR destination printed on the suspect box. Use its verification page or support channel to check the serial, batch, packaging, and authorised product identity.
Search official recalls and safety reports
Use the OPSS Product Safety Alerts, Reports and Recalls service. Match the brand, model, identifying numbers, images, and affected batch rather than reacting to a similar product name.
Ask the seller for an accountable answer
A credible seller should identify its supplier, the exact product record, replacement system where relevant, return route, and recycling service. Save the response, including a refusal or an unexplained mismatch.
Report the right problem
Send sales and authenticity evidence to the consumer or Trading Standards route. Use Yellow Card for a suspected side effect or nicotine e-cigarette safety concern. Follow an OPSS notice exactly when a recall matches.
The official checks a nicotine vape should survive
MHRA publication: the exact nicotine e-cigarette or refill product must be published on the relevant Great Britain or Northern Ireland list before legal supply. Search by brand and subtype, not only a broad manufacturer name. A missing result should be resolved with the retailer or submitter.
Nicotine and container presentation: MHRA guidance states a maximum nicotine concentration of 20mg/ml, a maximum 10ml refill container, and a maximum 2ml e-cigarette tank or cartridge for products sold to end consumers. A puff claim is not a substitute for the labelled liquid volumes.
Product and packaging requirements: nicotine products require child-resistant and tamper-evident features, warnings and information, ingredient restrictions, and a notification. Missing information can support a concern, but copied compliant-looking information does not prove authenticity.
Reusable design: a device supplied after the single-use ban must be rechargeable and refillable, with a replaceable coil where one is present and the relevant replacements separately available. A USB port alone does not satisfy the test.
Choose the next action from the strongest evidence
If the exact nicotine product is missing from the MHRA list
Pause use and ask the retailer to resolve the identity
MHRA guidance says the product is not compliant for supply until its notification is published on the relevant list.
Watch for: Search errors and variant naming can occur. A missing result supports escalation but does not by itself prove who made the unit.
If the code fails or the packaging differs, but the product is physically stable
Do not keep using it while authenticity is unresolved
The manufacturer and seller can compare the serial, batch, packaging revision, and supply route using more information than a visual checklist provides.
Watch for: A failed code can have benign technical causes, while a successful copied code can still mislead. Treat it as one clue.
If the device is single-use, over the stated nicotine limit, or otherwise visibly outside current rules
Do not buy, use, give away, or resell it
The observable issue is enough to avoid the product and document the seller for a Trading Standards report.
Watch for: Do not dismantle it to look for further offences. Preserve safe photographs and packaging instead.
If the device is hot, swollen, hissing, smoking, leaking badly, or activating itself
Treat it as a safety incident, not an authenticity puzzle
Battery or liquid exposure can require immediate precautions regardless of whether the product is genuine.
Watch for: Do not post, transport, or return a dangerous battery without instructions. Call 999 for smoke or fire and seek appropriate medical help for exposure or symptoms.
Report the seller, product, and health concern through the right routes
Illegal, counterfeit, unsafe, or misdescribed sale: in England, Citizens Advice says consumers report to Trading Standards through its consumer service. Routes differ across Scotland, Wales, and Northern Ireland, and some local authorities accept direct illegal-vape reports. GOV.UK and local authority pages can identify the current route.
Suspected side effect or nicotine e-cigarette safety concern: use the MHRA Yellow Card scheme. A report records a suspicion, not proof of causation. Include the exact brand, subtype, batch, strength, where it was bought, how it was used, and what happened. Seek medical help separately when needed.
Recall or official safety action: follow the OPSS notice. It may require stopping use, returning a particular batch, arranging a repair, or seeking a replacement or refund. Do not assume a notice for a similarly named product applies to yours.
Keep the receipt, payment record, seller name and address, web address, order confirmation, listing screenshots, packaging, batch details, and correspondence. Retain the device only if doing so is safe and consistent with official instructions. Never send a vape or battery through the post without the carrier and recipient explicitly accepting it.
Return or recycle the device without creating another risk
Do not put a vape in household rubbish or normal kerbside recycling. Waste equipment can be crushed, damaging a lithium battery and creating a fire. Retailers selling vapes have take-back obligations, and household waste recycling centres provide routes for small electrical items and batteries.
For a stable device, keep it switched off, protect it from damage, and ask the retailer or recycling service how it should be presented. Remove a user-removable cell only when the product and recycler instructions support doing so, then protect the terminals. Do not puncture a built-in battery or empty an unknown liquid into a sink.
A hot, swollen, hissing, smoking, leaking, or damaged unit is not routine recycling. Ask the fire service, retailer, manufacturer, or local recycling service for situation-specific instructions without transporting it first. If it smokes or burns, leave and call 999.
Common questions about suspected fake vapes
Can a QR code prove a vape is genuine?
No. A code and its destination can be copied. Reach the manufacturer website independently, then use its verification tool and support contact. Combine that result with the exact MHRA record, legal format, seller evidence, and physical inspection.
Does a low price mean a vape is fake?
No. A price far outside the normal range can justify more checks, but legitimate clearance and counterfeit products sold at full price both exist. Price does not identify liquid contents, manufacturer, or legal status.
Does an MHRA listing prove my unit is genuine?
No. It shows that a product identity has a published notification, which is required before legal supply. A counterfeit unit can copy the identity of a listed product. Match the exact variant and verify the physical unit and supply route separately.
Is every illegal vape counterfeit?
No. A genuine-brand product can be supplied illegally, exceed UK presentation limits, lack the relevant notification, or fail the reusable-device rule. Counterfeit refers to false identity; illicit and non-compliant refer to legal or regulatory problems.
What should I do if a vape makes me feel unwell?
Stop using it and seek medical help appropriate to the symptoms. Use 999 for an emergency. You can also report the suspected side effect and product details through the MHRA Yellow Card scheme. A report does not replace healthcare.
Should I return a swollen or hissing vape to the shop?
Do not transport it without situation-specific instructions. Stop using and charging it, keep people away, and contact the retailer, manufacturer, local recycling service, or fire service for safe handling advice. If it smokes or catches fire, get out and call 999.
Where do I report a shop selling suspected illegal vapes?
Use the current Trading Standards reporting route for your UK nation or local authority. In England, Citizens Advice directs reports through its consumer service. Include the seller, address or URL, purchase details, exact product, photos, and why it appears illegal.
