Frequently Asked Questions About Vaping & E-Liquids

E-liquid is the flavoured vape juice that powers every refillable vape kit, pod system, and sub-ohm device. It is made from vegetable glycerin (VG), propylene glycol (PG), food-grade flavourings, and optional pharmaceutical-grade nicotine. When you draw on your device, a coil heats the e-liquid into an inhalable vapour. Scent Vape stocks the complete range of UK e-liquids including nicotine salt e-liquid, 10ml freebase vape juices, and high-VG shortfills — all TPD compliant and dispatched with free delivery on orders over £25.

Freebase nicotine e-liquid delivers a stronger, more noticeable throat hit and is most commonly available at 3mg, 6mg, or 12mg in 10ml bottles. Nicotine salt e-liquid uses a chemically modified formula that absorbs into your bloodstream faster and feels significantly smoother even at higher concentrations like 10mg or 20mg. If you are switching from cigarettes or stepping away from disposable vapes, a nicotine salt vape juice gives you faster craving relief without the harshness that high-strength freebase causes.

The correct VG/PG ratio depends entirely on your device type. MTL pod kits and vape pen devices use a 50/50 vape liquid for smooth wicking through tight coils and a firm throat hit. Sub-ohm and direct-to-lung devices require a 70VG/30PG or higher blend to support large wicking ports and produce the dense clouds these kits are designed for. Using a high VG shortfill e-liquid in a pod kit not designed for it will cause dry hits, burnt flavour, and shortened coil life — always match the ratio to your device.

If you smoked 10 or more cigarettes a day, start with a 20mg nicotine salt vape juice in a compact pod kit. This delivers fast, smooth nicotine that closely replicates the hit of a cigarette without harshness. Lighter smokers typically do well at 10mg nic salt or 6mg freebase. Heavier smokers who feel 20mg is still not enough should consider a hybrid nicotine formula. You can reduce your chosen strength gradually over time as your nicotine dependency decreases. Browse our nicotine salt e-liquid range for the full selection of strengths and flavours.

A shortfill e-liquid is a large-format, nicotine-free vape juice sold in a deliberately under-filled bottle, leaving space for you to add nicotine shots after purchase. A standard 100ml shortfill comes in a 120ml bottle with 20ml of empty space for two 10ml nic shots. Adding two 18mg freebase shots gives you approximately 120ml of e-liquid at around 3mg final strength. Shortfill vape juice is designed for sub-ohm and direct-to-lung devices, and offers significantly better value per ml than buying multiple small 10ml bottles. Browse our full 100ml shortfill e-liquid range at Scent Vape.

The average vaper uses between 2ml and 5ml of vape juice per day depending on their device wattage and frequency of use. MTL pod kit users typically consume 2ml to 3ml daily, meaning a single 10ml nicotine vape juice bottle lasts around three to five days. Sub-ohm vapers using shortfill e-liquid at higher wattages can use 5ml or more per day, making 100ml shortfills a far more cost-effective option for daily use. Chain vapers or those using high-powered devices should budget for more liquid per week.

Yes. All nicotine-containing e-liquids sold in the UK must comply with the Tobacco Products Directive (TPD) and carry UKCA markings. TPD regulations restrict nicotine vape juice bottles to a maximum of 10ml and cap the nicotine concentration at 20mg per ml. All products must have full ingredient lists submitted to the MHRA before they can legally be sold. Every e-liquid at Scent Vape is sourced from verified manufacturers who meet these legal requirements. Shortfill vape juices are nicotine-free and are therefore not subject to the 10ml bottle restriction, which is why they are sold in larger 100ml formats.

Standard 70VG shortfill e-liquid is not suitable for low-powered pod kits. The thick consistency cannot wick quickly enough through small pod coils, resulting in dry hits, burnt flavour, and significantly shortened coil life. Pod kit users should choose a 50/50 nicotine salt e-liquid or a 50/50 freebase vape juice instead. Some shortfill ranges are produced in a 50/50 ratio and may be compatible with certain pod devices — always check the VG/PG blend printed on the bottle before filling your pod to protect both your coil and your vaping experience.

For beginners, the best e-liquid is a 50/50 nicotine salt vape juice at 10mg or 20mg used in a compact starter kit or vape pen device. Nic salts provide smooth, fast-acting nicotine delivery that closely mirrors the satisfaction of smoking, making the initial transition much more manageable. A simple vape starter kit paired with a 10ml nic salt in a fruit or menthol flavour is the most popular combination at Scent Vape for first-time vapers and people switching from cigarettes.

Sub-ohm vape kits require a high VG vape juice, typically 70VG/30PG or higher, to handle the large wicking ports found in low-resistance coils operating below 0.5 Ohm. Shortfill e-liquid is the standard choice for sub-ohm setups because it comes in larger volumes, is nicotine-free until you add nic shots, and delivers the bold flavour and dense clouds these kits are built for. Most sub-ohm vapers use a final nicotine strength of around 3mg for comfortable all-day vaping. Explore our advanced sub-ohm kits alongside our shortfill range for a complete setup.

Adding a nic shot to a shortfill e-liquid is straightforward. Remove the cap and the inner pipette nozzle from your shortfill bottle to expose the opening. Squeeze your chosen nicotine shot into the bottle — use one 10ml shot for a 50ml shortfill and two shots for a 100ml shortfill. Replace the lid firmly, then shake gently for around 20 seconds to blend the liquids. Allow the bubbles to settle for a few minutes before filling your tank or pod. Adding one 18mg freebase nic shot to a 50ml shortfill vape juice gives approximately 3mg final nicotine strength — the most common level used by sub-ohm vapers.

Unopened e-liquid bottles have a shelf life of up to two years when stored correctly in a cool, dark environment away from heat and sunlight. UV light and high temperatures gradually degrade both the nicotine and the flavouring in vape juice, causing the liquid to darken and taste weaker over time. Once opened, use your e-liquid within three to six months for the best flavour and consistent nicotine performance. All e-liquid bottles sold at Scent Vape carry a printed best-before date and comply fully with UK labelling standards set by the MHRA.

Hybrid nicotine e-liquid blends both freebase nicotine and nicotine salts within a single formulation. The result combines the rapid absorption and smoothness of nic salts with the sharper flavour delivery and familiar throat character of freebase. Hybrid nicotine vape juice is ideal for vapers who want a more assertive hit from a pod kit without the full harshness of high-strength freebase e-liquid alone. In the UK, hybrid liquids are sold in 10ml TPD-compliant bottles with a maximum strength of 20mg, and they are compatible with the same pod and pen kit devices used for standard nicotine salt e-liquid.

For smokers making the switch to vaping, the best vape kit is a compact MTL starter kit or vape pen device paired with a 20mg nicotine salt e-liquid. The mouth-to-lung draw closely replicates the inhalation style of a cigarette, and the 20mg nic salt provides the fast, smooth nicotine hit needed to satisfy cravings without harshness. Our vape starter kits are specifically curated with beginners in mind, featuring easy-to-use devices that are simple to fill, charge, and maintain right from the first day.

MTL stands for mouth-to-lung vaping — the technique of pulling vapour into your mouth first and then inhaling it into your lungs, which is the same natural action as smoking a cigarette. MTL vaping uses higher-resistance coils above 1.0 Ohm, lower wattage outputs, and thinner 50/50 vape liquids or nicotine salts. The draw is tight and restricted, making it the most familiar feel for anyone transitioning from smoking. Most vape pen kits and pod starter kits sold at Scent Vape are optimised for MTL vaping.

Store your e-liquid bottles upright in a cool, dark location away from direct sunlight, heat sources, and radiators. UV light and high temperatures degrade both the nicotine and the flavouring in vape juice over time, causing the liquid to darken and the taste to weaken. Avoid leaving e-liquid in cars or on windowsills where temperatures fluctuate significantly. Properly stored, unopened bottles retain their quality for up to two years. Always keep all e-liquid — including nicotine-free shortfill vape juice — out of reach of children and pets at all times.

Yes. Zero nicotine vape juice is available at Scent Vape in two main formats. All 100ml shortfill e-liquids are supplied at 0mg by design — you add nicotine shots after purchase only if you want them, or vape them as-is for a completely nicotine-free experience. Some 10ml freebase ranges also offer a 0mg option. Nicotine-free vape juice is ideal for vapers who have stepped down their nicotine intake to zero and simply enjoy the flavour and act of vaping. Browse our shortfill e-liquid collection for the full zero-nicotine range.

Every e-liquid is built from the same four core ingredients: vegetable glycerin (VG), propylene glycol (PG), food-grade flavouring concentrates, and nicotine in products that contain it. VG produces vapour and delivers a smooth inhale. PG carries flavour more sharply and produces the throat hit. All flavouring compounds used in UK-compliant vape juice must be food-safe and declared to regulators under TPD rules before a product can be sold legally. Every e-liquid at Scent Vape is transparently labelled with its full ingredient list, nicotine content, and UKCA compliance markings.

The Elux Legend nic salt e-liquid is a 10ml nicotine salt vape juice inspired by the bold flavour profiles made famous by the Elux Legend disposable device. Available at 10mg and 20mg, it delivers the same intensely fruity taste in a format designed for refillable pod kits — giving you far better value and significantly less plastic waste than single-use disposables. Popular flavours include blueberry cherry cranberry, strawberry ice cream, kiwi passionfruit guava, and banana ice. Browse the full Elux Legend nic salt range at Scent Vape.

Most refillable vape pods have either a top-fill or side-fill port sealed by a rubber stopper or sliding cap. Remove the pod from the device, locate the fill port, open it, and insert the nozzle of your e-liquid bottle directly into the opening. Fill slowly until the nicotine vape juice reaches the maximum fill line marked on the pod, then reseal the port firmly to prevent leaking. Before vaping, wait three to five minutes to allow the coil to fully saturate with liquid. Vaping immediately after filling before saturation is complete risks a dry hit that can permanently damage the coil and shorten its lifespan.

The most popular e-liquid flavours in the UK are fruity and icy profiles. Strawberry ice, blueberry raspberry, watermelon ice, and kiwi passionfruit consistently top the sales charts across both nic salt and shortfill formats. Menthol and mint combinations remain a firm favourite among ex-menthol cigarette smokers. Cola, pink lemonade, and tropical blends offer popular alternatives for vapers looking for a change. Classic tobacco vape juice remains a reliable seller for vapers who prefer familiarity over sweetness. Scent Vape stocks a wide selection across all flavour categories in our nicotine salt e-liquid range.

MTL (mouth-to-lung) vaping uses a tight, restricted draw, high-resistance coils above 1.0 Ohm, low wattage, and 50/50 vape liquids or nicotine salts — it closely mimics the experience of smoking a cigarette. DTL (direct-to-lung) vaping uses an open, airy draw, low-resistance sub-ohm coils below 0.5 Ohm, higher wattage outputs of 40W or above, and high VG shortfill e-liquid. DTL produces significantly larger clouds and more intense flavour but is not suited to high nicotine strengths. Most beginners start with MTL vaping and some progress to DTL as their experience and preferences evolve.

No — many vape juices are completely nicotine free. Shortfill e-liquids are always supplied at 0mg and contain no nicotine until you choose to add a nic shot after purchase. Some 10ml ranges also offer a 0mg freebase option. Nicotine-free vape juice lets you enjoy the full flavour and vapour experience without any nicotine dependency. For vapers who have gradually reduced their intake, stepping down to zero nicotine e-liquid is a natural final stage in transitioning completely away from nicotine.

Both Aspire and OXVA produce well-reviewed MTL pod kits that work with nicotine salt and freebase vape liquids. Aspire kits are recognised for their build quality, coil durability, and consistent flavour delivery. OXVA kits — particularly the Xlim series — are popular for their compact design, strong draw, and broad coil compatibility. Your choice comes down to personal preference for device size and coil availability. Scent Vape stocks both brands; browse our Aspire vape kits and OXVA vape kits side by side to compare.

Yes — switching from disposable vapes to a refillable vape kit with separate e-liquid is substantially cheaper over time. A disposable vape that lasts one to two days costs around £5 to £6, adding up to over £150 a month for a heavy daily user. A refillable pod kit costs between £15 and £30 as a one-time purchase, and a 10ml nicotine salt vape juice costs as little as £2.99 and lasts three to five days. A vape starter kit from Scent Vape typically pays for itself within the first week of switching away from disposables.

A vape pen kit is a slim, cylindrical refillable vape device designed for MTL vaping. Vape pens are one of the most beginner-friendly devices available — they have a simple single-button or inhale-activated design, easy top or side filling, and are fully compatible with 50/50 nicotine salt e-liquid and freebase vape juice. They suit ex-smokers who want a familiar, cigarette-shaped experience in the hand. Our vape pen kits are among the most straightforward devices to start with at Scent Vape and require no prior vaping knowledge to use correctly.

TPD stands for Tobacco Products Directive — the UK regulation governing all nicotine-containing vaping products sold in Britain. Under TPD rules, nicotine vape juice must be sold in bottles no larger than 10ml, nicotine concentrations are capped at 20mg per ml, and all products must carry UKCA labelling and have their full ingredient lists submitted to the MHRA. Every nicotine-containing e-liquid sold at Scent Vape is TPD compliant, so you can purchase with complete confidence that your vape juice meets the safety and labelling standards required by UK law.

A burnt taste from your vape is almost always caused by a dry or worn-out coil. The most common reasons for a dry coil are: vaping before the coil has fully saturated with e-liquid after a fresh fill, allowing the pod or tank to run too low on vape juice, chain vaping without giving the wick time to re-saturate between puffs, or using a thick high VG shortfill in a pod kit designed for 50/50 nicotine salt e-liquid. When the burnt taste persists, replace the coil or pod and allow five minutes for the fresh coil to absorb e-liquid fully before vaping again.

The resistance rating of your coil determines which vape liquid is compatible with it. Coils above 1.0 Ohm are built for MTL vaping and require 50/50 nicotine salt e-liquid or 50/50 freebase vape juice. Coils between 0.5 and 1.0 Ohm work with 50/50 blends and some lighter high VG e-liquids. Coils below 0.5 Ohm are sub-ohm coils that require a high VG shortfill e-liquid of at least 70VG. Check your coil packaging or device manual for the recommended e-liquid type — pairing the wrong ratio to your coil is the single most common cause of dry hits, poor flavour, and early coil failure.

The most cost-effective way to vape in the UK is to use a refillable pod kit or vape pen with separate 10ml nicotine salt e-liquid or 100ml shortfill vape juice. Avoid single-use disposables as a daily solution — the cost per puff is far higher than buying your own device and e-liquid separately. Sub-ohm vapers save the most by purchasing 100ml shortfills, which offer much better value per ml than multiple 10ml bottles. Ordering over £25 from Scent Vape also qualifies for free UK delivery, reducing your overall cost every time you restock your vape juice.

A vape coil typically lasts between one and three weeks depending on how frequently you vape and which e-liquid you use. High VG shortfill vape juice and heavily sweetened flavour profiles tend to gunk up coil cotton faster than lighter 50/50 nicotine salt e-liquids. Signs your coil needs replacing include a persistent burnt or muted flavour, reduced vapour production, and a gurgling sound when you inhale. Always prime a new coil by filling the tank and waiting five minutes before the first puff — this single step significantly extends coil lifespan by preventing the cotton burning before it has fully saturated.

Yes — mixing two different vape juice flavours is safe provided both liquids share the same VG/PG ratio and the same nicotine type. Combining two 50/50 nicotine salt e-liquids will produce a blended flavour with a nicotine level averaging the two strengths. Mixing a high VG shortfill with a 50/50 nic salt is not recommended as the differing ratios can negatively affect wicking performance in your device. Start by mixing small amounts to test the flavour combination before committing to mixing larger quantities together.

For maximum cloud production, you need a sub-ohm vape kit running at 40W or above with a coil resistance below 0.5 Ohm, paired with a high VG shortfill e-liquid at 70VG or higher. The high vegetable glycerin content of the vape juice produces dense, voluminous vapour, and mesh coil technology further enhances output by providing a larger heated surface area. Our advanced sub-ohm kits combined with 100ml shortfills offer the complete cloud-chasing setup — all available with free UK delivery on orders over £25.

Vape leaking is most commonly caused by overfilling the pod, using a VG/PG ratio that is too thin or too thick for the coil, a worn or damaged coil that is no longer sealing properly, or not closing the fill port firmly after adding vape liquid. Always fill just below the maximum fill line, ensure the fill cap is firmly sealed, and confirm that your nicotine salt e-liquid or freebase vape juice matches the recommended viscosity for your device. Replacing worn coils promptly and matching your liquid ratio to your coil type eliminates the majority of leaking issues.

Most Aspire pod kits and pen devices use coils above 0.6 Ohm and are optimised for MTL vaping with 50/50 nicotine salt e-liquid or 50/50 freebase vape juice. Some Aspire kits such as the BP Stik support a broader wattage range and can use higher VG e-liquids at elevated wattage settings for DTL vaping. Always check your specific Aspire device's user manual for the recommended coil resistance and compatible e-liquid type. Pairing any Aspire MTL kit with a 10mg or 20mg nicotine salt e-liquid delivers the best combination of flavour and coil longevity.

Yes. The minimum legal age to purchase e-liquid, vape kits, and all vaping products in the UK is 18. It is a criminal offence to sell nicotine vape juice, nicotine-free shortfill e-liquid, or any vaping accessory to anyone under 18 years old. Scent Vape complies fully with this law and carries out mandatory age verification at checkout for every order. All products listed on our site are strictly intended for adult use only. Do not attempt to purchase from Scent Vape if you are under 18.

A nicotine shot is a small 10ml bottle of unflavoured nicotine liquid — available in either freebase or salt nicotine format — designed specifically to be added to a nicotine-free shortfill e-liquid to achieve your desired final nicotine strength. One 18mg freebase nic shot added to a 50ml shortfill vape juice gives approximately 3mg strength. Two shots added to a 100ml shortfill also gives around 3mg. To use: open your shortfill, squeeze in the nic shot, reseal the bottle, and shake well for 20 seconds before filling your tank. The process takes less than two minutes and makes shortfill vape juice fully customisable to your needs.

Some of the most recognised e-liquid brands in the UK include Elux, IVG (I Vape Great), Dinner Lady, Riot Squad, Bar Juice, and Vampire Vape. In the nicotine salt category, brands tied to popular disposable devices — particularly Elux — sell strongly because vapers already recognise and trust the flavour profiles from their disposable experience. At Scent Vape, every brand in our collection is selected based on quality, TPD compliance, and flavour consistency. Browse our nic salt e-liquid collection to explore the brands we stock.

50/50 on an e-liquid bottle indicates the vape juice contains equal parts — 50% vegetable glycerin and 50% propylene glycol. This balanced blend has a thinner consistency that wicks easily and quickly into the smaller coils used in MTL pod kits and vape pen devices. It delivers a noticeable throat hit alongside clear, well-defined flavour. A 50/50 vape liquid is compatible with the widest range of devices and is the most versatile e-liquid format available, making it the default recommendation for pod kit users and beginners choosing their first nicotine vape juice.

E-liquid darkening in the bottle is the result of nicotine oxidation — a normal chemical reaction that occurs when nicotine is exposed to air, light, or heat over time. This colour change does not automatically mean the vape juice is unsafe or unfit to use. However, if the flavour has become noticeably weaker, unpleasant, or significantly off compared to when you first opened it, the e-liquid may have degraded past its best. Store all vape liquid correctly in a cool, dark place with the lid sealed tightly to slow oxidation and maintain flavour quality for as long as possible.

Scent Vape offers free UK delivery on all orders over £25. This threshold applies across all product categories including e-liquids, vape kits, replacement coils, and accessories. To qualify, ensure your basket total reaches £25 before proceeding to checkout. Stocking up on several 10ml nicotine salt e-liquid bottles, buying a 100ml shortfill, or adding a replacement coil pack alongside your vape juice order are easy ways to reach the free delivery threshold while making sure you have enough supplies to last. All orders are dispatched promptly from our UK warehouse.

Yes — buying e-liquid online is completely legal for adults aged 18 and over in the UK. Online vape retailers like Scent Vape offer a significantly wider selection of vape flavours, better value pricing, and more convenient home delivery than most high street shops. All UK online retailers selling nicotine vape juice are legally required to age-verify customers at checkout and sell only TPD-compliant products. At Scent Vape, age verification is built directly into our checkout process to ensure every purchase meets UK legal requirements before dispatch.

Bar salts are a sub-category of nicotine salt e-liquid specifically formulated to replicate the bold, punchy flavour profiles made famous by disposable bar vapes. They use higher flavour concentrations for an immediately intense taste from the first puff. Classic nic salts offer more layered, nuanced flavour profiles similar in character to traditional freebase vape juice but with the smoother delivery of salt nicotine. Both formats are sold in 10ml TPD-compliant bottles at 10mg and 20mg and are fully compatible with MTL pod kits. If you enjoyed the taste of a specific disposable bar vape, bar salt e-liquid is the closest refillable equivalent.

Empty any remaining e-liquid from your pod or tank before cleaning. Rinse the pod or tank thoroughly under warm running water to flush out residual vape juice. For tanks with removable components, disassemble each part and rinse separately. Lay all parts flat on a paper towel and allow them to air-dry completely — this takes 30 minutes to an hour depending on the size. Never reassemble before fully dry, as even a small amount of water remaining inside can cause spitting or coil damage. Cleaning between flavour changes prevents old vape juice from contaminating your fresh e-liquid.

Vape pen kits perform best with 50/50 nicotine salt e-liquid or 50/50 freebase vape juice. The thin consistency of a 50/50 blend wicks quickly through the narrow coils used in pen-style devices, delivering clean, consistent flavour from the first puff. Most vape pen coils sit above 1.0 Ohm and are not designed to handle the thick consistency of high VG shortfill e-liquid. A 10mg or 20mg nicotine salt vape juice in a fruit, menthol, or tobacco flavour is the most popular e-liquid choice among vape pen kit users at Scent Vape.

Yes. Scent Vape regularly offers discounted vape kits through our clearance section, where you can find premium devices at reduced prices — ideal if you want to try a high-quality kit without the full retail cost. All clearance items at Scent Vape are genuine, authentic products subject to the same quality standards as our full-price range. These are fully functional devices, not refurbished units. Visit our vape kit clearance collection to see the latest discounted devices currently available.

A vape starter kit is a broad category that covers any beginner-appropriate device — this includes pod kits, pen kits, and compact tube-style devices. A pod kit specifically refers to devices that use a detachable pod cartridge to hold e-liquid, which can be removed and swapped quickly when empty or when you want to change flavour. Both categories are compatible with 50/50 nicotine salt e-liquid and 50/50 freebase vape juice. Our vape starter kits at Scent Vape include devices designed for total beginners with no previous vaping experience required.

If your vape produces no vapour, the most common causes are a depleted battery that needs charging, an empty or critically low pod, a burned-out coil that needs replacing, a blocked or partially closed airflow vent, or a loose connection between the pod and the device body. Check the battery level first, then inspect the e-liquid level in your pod. If the coil tastes burnt or the flavour has degraded noticeably, replace it. Ensure the pod is firmly clicked into place and that the air intake vent on the base of the pod is fully open and unobstructed before trying again.

For cloud-focused sub-ohm vaping, the best approach is adding a low-strength freebase nicotine nic shot to a high VG shortfill e-liquid. Most cloud vapers use a final nicotine strength of 3mg freebase for comfortable all-day DTL vaping. Nicotine salt e-liquid is not recommended for high-wattage sub-ohm devices because the large vapour volume delivers nicotine far too rapidly at 10mg or 20mg, making the experience uncomfortably intense. Keep nicotine low when cloud chasing and prioritise finding a 100ml shortfill flavour you genuinely enjoy. Browse our shortfill e-liquid range for all available options.
