Nic Salt vs Freebase E-Liquid UK 2026: Which Should You Vape?

TL;DR: Nic salt e-liquid is smoother, absorbs in about 30 seconds and suits low-wattage pod kits at 10mg or 20mg — best for ex-smokers and disposable switchers. Freebase is harsher, produces bigger clouds and suits sub-ohm tanks at 3mg or 6mg — best for hobbyist cloud vapers. For most UK vapers in 2026, nic salts win.

TL;DR: Nic salt e-liquid is smoother, absorbs faster and works best in low-wattage pod kits at 10mg or 20mg — ideal for ex-smokers and disposable switchers. Freebase e-liquid is harsher, produces bigger clouds and works best in sub-ohm tanks at 3mg or 6mg — ideal for experienced hobbyist vapers. For most UK vapers in 2026, nic salts win.

Nic Salt vs Freebase: The Short Answer

Nic salt is freebase nicotine chemically bonded with an organic acid (usually benzoic acid) to lower its pH, making high-strength nicotine smooth enough to inhale from a small pod device. Freebase is the traditional alkaline form of nicotine, which is why it feels harsh above 6mg and is now mostly used in low-strength, high-wattage sub-ohm tanks. Post the June 2025 UK disposable vape ban, nic salts in refillable pods have become the default format for adult smokers switching away from cigarettes.

This guide is the definitive UK 2026 comparison. It covers the chemistry, the hardware, the strengths, the flavour profile, the cost per puff, the regulatory landscape (MHRA, TPD, the October 2026 HMRC excise duty), and which format suits which type of vaper. Every claim is grounded in either UK regulation, NHS cessation guidance or real 2026 retail pricing from mainstream British retailers.

Quick verdict by vaper type

• Ex-smoker switching from 10-a-day or more: 20mg nic salt in a refillable pod (Elf Bar Elfa Pro, Lost Mary Tappo, Uwell Caliburn G3).
• Ex-smoker switching from under 10-a-day: 10mg nic salt in the same pod hardware.
• Disposable refugee post-June 2025 ban: Big-puff refillable pod kits with 20mg nic salt (Hayati Pro Ultra 25K, IVG 2400 refillable).
• Cloud chaser / hobbyist: 3mg or 6mg freebase in a sub-ohm tank (Vaporesso GEN 200, Voopoo Drag X Plus).
• Occasional social vaper: 5mg or 10mg nic salt in a small AIO pod.

What Is Freebase Nicotine?

Freebase nicotine is the pure, unprotonated alkaloid extracted from tobacco leaf, first isolated in a commercial form in the 1960s and used in cigarettes to increase the speed and potency of nicotine delivery. In e-liquid, it has been the standard since the modern vape was patented in 2003. Freebase is naturally alkaline, sitting at a pH of roughly 8 to 9, which is what produces the classic sharp "throat hit" vapers describe.

Why cigarette companies invented freebase

The freebase process was popularised by Philip Morris in the 1960s and used in Marlboro to accelerate nicotine absorption in the lungs. It was the reason a smoker felt satisfied within seconds. When the modern e-cigarette arrived in the mid-2000s, freebase was the only nicotine form vape manufacturers used, because it was the only form the supply chain understood.

Freebase e-liquid characteristics in 2026

• Alkaline pH (8-9), harsh above 6mg.
• Common strengths in the UK: 0mg, 3mg, 6mg (12mg and 18mg exist but are rare in modern kits).
• VG:PG ratios typically 70/30 or 80/20 for big-cloud sub-ohm vaping.
• Sold as 10ml TPD-compliant bottles or 50ml/100ml/200ml "shortfills" (nicotine-free base) plus separate 18mg nic shots.
• Absorbs into the bloodstream in around 2-3 minutes — slower than a cigarette.

What Is Nic Salt E-Liquid?

Nic salt is freebase nicotine reacted with an organic acid — most commonly benzoic acid — to form a nicotine salt with a much lower pH (around 6-7). This near-neutral pH makes it far smoother on the throat at high strengths and allows for faster absorption into the bloodstream, mimicking the satisfaction curve of a cigarette. Nic salts were introduced commercially by Pax Labs (Juul) in 2015 and became mainstream in the UK from around 2019.

Why nic salts took over the UK market

Between 2019 and 2024 the UK vape category shifted decisively toward high-strength pod devices — first the Juul, then the Elf Bar 600, then the whole disposable wave. All of these ran nic salt because freebase at 20mg is undrinkable in a small pod. By 2024 the ONS reported that 5.9 million UK adults were vaping, most of them on 20mg nic salt in a pod. When the disposable ban landed in June 2025, that population moved not back to freebase but to refillable pods running the same 20mg nic salt formulation.

Nic salt e-liquid characteristics in 2026

• Near-neutral pH (6-7), smooth even at the 20mg legal maximum.
• Common strengths in the UK: 5mg, 10mg, 20mg. Never above 20mg — that is the TPD legal cap.
• VG:PG ratios typically 50/50 for MTL pod use.
• Sold exclusively as 10ml TPD-compliant bottles (shortfills are not possible above 6mg legally).
• Absorbs into the bloodstream in around 30 seconds — closer to a cigarette.

Chemistry Explained (Without The Boring Bits)

Nicotine exists in two states: the protonated form (nicotine salt) and the unprotonated form (freebase). Freebase has a lone pair of electrons on the nitrogen atom that makes it alkaline and volatile — great for vaporising at low temperatures, but harsh on human tissue. Adding benzoic acid donates a proton to that nitrogen, forming a salt: same nicotine molecule, radically different behaviour on the throat and in the bloodstream.

Why benzoic acid specifically

Benzoic acid is used because it is food-grade (E210, approved by the UK Food Standards Agency), has the right dissociation constant to protonate nicotine at vape-relevant temperatures, and does not degrade coil materials the way stronger acids would. Some Chinese manufacturers use citric or malic acid variants ("smooth salts"), but benzoic remains the industry standard in UK-notified products via the MHRA.

What that means in the pod

Because the salt is more thermally stable, it vaporises efficiently at the low 8-15W wattages of a pod device, whereas freebase needs 40W+ in a sub-ohm coil to produce the same visible cloud. This is the single most important practical distinction: nic salt is engineered for small kits, freebase for big kits.

The clearest way to see the difference is a direct side-by-side. This is the reference table UK retailers use when advising customers switching from disposables in 2026.

Which Should You Vape? Decision Guide By Smoker Profile

The right choice depends almost entirely on how you used to smoke and what hardware you already own. Here is the breakdown UK vape shop staff give behind the counter.

If you smoked 20+ a day and want a cigarette-like hit

Go 20mg nic salt in a refillable pod kit. This is the closest thing to the throat satisfaction of a Marlboro Red. Recommended 2026 hardware: Uwell Caliburn G3 Pro (£25.99), Elf Bar Elfa Pro (£8.99), Lost Mary Tappo Air (£12.99). Recommended e-liquid: Elfliq Blueberry Sour Raspberry, Lost Mary Blueberry Cherry Cranberry, Bar Juice 5000 Watermelon Ice.

If you smoked 10-20 a day

Start on 20mg nic salt, but expect to drop to 10mg within 6-8 weeks. Same hardware as above works. Do not step down too quickly — under-dosing causes relapse.

If you smoked under 10 a day or were a social smoker

Go 10mg nic salt from day one. Anything higher will feel nauseating. Consider a small AIO pod like the Vaporesso XROS 4 (£19.99) or OXVA Xlim SQ Pro (£17.99).

If you already vape freebase at 3mg or 6mg

Stick with freebase in your sub-ohm kit. There is no medical or practical reason to switch. Just make sure your hardware is TPD-compliant and coils are within their intended resistance range.

If you want to eventually quit nicotine entirely

Freebase is easier to titrate down because it comes in 3mg increments and 0mg is widely available. NHS cessation advice, however, is that many vapers can continue to use nicotine long-term as harm-reduction — quitting the nicotine altogether is not medically necessary if you have already quit tobacco.

Best Kits for Nic Salt in the UK 2026

Nic salts need low-wattage, higher-resistance mouth-to-lung (MTL) pod hardware. Using them in a sub-ohm tank at 60W would deliver a nicotine dose several times higher than intended and taste burnt. The following kits are the current UK 2026 gold standards for salt use, all TPD-compliant and available from mainstream UK retailers.

Browse the full range at /vape-kits or shop replacement pods and prefilled cartridges at /vape-pods.

Post-disposable-ban context

The Environment Act 2021 secondary legislation banning single-use disposable vapes came into force on 1 June 2025. This means every Elf Bar 600, Lost Mary BM600 and Crystal Bar of that era is now illegal to sell new in the UK. What replaced them is the near-identical big-puff refillable format — the Hayati Pro Ultra 25K, IVG 2400, Crystal Bar 4000 refillable — all of which run 20mg nic salt in a replaceable pod. From a chemistry point of view, nothing changed. From a landfill point of view, everything did.

Best Kits for Freebase in the UK 2026

Freebase e-liquid at 3mg or 6mg belongs in a sub-ohm tank. The point of this hardware is cloud production and rich flavour extraction, not high-strength nicotine delivery. If you own any of the following, freebase is what you want.

Nicotine Strengths Explained: Which Should You Use?

UK law caps e-liquid nicotine at 20mg/ml under the Tobacco and Related Products Regulations 2016 (TRPR), which enacted the EU TPD and was retained post-Brexit. The MHRA is the UK regulator and every notified e-liquid product must be listed on their register. Any e-liquid over 20mg sold in the UK is illegal — full stop.

Nic salt strength ladder

• 5mg: Light — for social vapers or those already stepping down from 10mg. Rare in the UK, more common in EU imports.
• 10mg: Standard mid-strength. Suits vapers who smoked under 15 a day.
• 20mg: Legal maximum. Suits heavy ex-smokers and disposable switchers. The default for anyone coming from an Elf Bar or Lost Mary.

Freebase strength ladder

• 0mg: Nicotine-free — for flavour enthusiasts or the final step down. Available in every shortfill.
• 3mg: Most popular sub-ohm strength. Enough hit at 60W to feel satisfying without harshness.
• 6mg: Upper limit of comfort at sub-ohm wattage. Some vapers pair 6mg with lower-wattage MTL tanks.
• 12mg / 18mg: Legacy strengths for old-school cig-a-like devices. Now uncommon and increasingly hard to source.

Nic-shot maths for shortfills

Because TPD limits any e-liquid containing nicotine above 0mg to a 10ml bottle, larger 50ml, 100ml or 200ml bottles are sold as "shortfills" — nicotine-free base you add nic shots to. An 18mg 10ml nic shot added to a 50ml shortfill (giving 60ml total) produces roughly 3mg. Two nic shots into a 100ml shortfill (120ml total) also gives 3mg. Three shots into a 100ml short (130ml) yields around 4mg. This is a legal workaround, not a loophole — the MHRA fully permits it.

Flavour: Which Format Tastes Better?

Freebase generally produces richer, more layered flavour because it is vaporised at higher temperatures across more surface area on a large mesh coil, extracting more nuance from complex custard, dessert or tobacco recipes. Nic salt, run in small pods, tends to deliver bright, fruit-forward, ice-heavy profiles because that is what the format does best. Neither is objectively "better" — they are engineered for different palates.

Where nic salt flavour shines

• Ice fruits: Elfliq Blueberry Sour Raspberry, Lost Mary Blueberry Cherry Cranberry, Bar Juice 5000 Watermelon Ice.
• Simple sweets: Nasty Juice Cush Man, Riot Squad Punx Guava Passionfruit Pineapple.
• Menthol / cool mint: Doozy Vape Salts Peppermint, IVG Salts Menthol Tobacco.

Where freebase flavour shines

• Custards & desserts: Dinner Lady Lemon Tart, Nasty Juice Cushman, Vampire Vape Pinkman.
• Tobacco blends: Riot Squad RY4, Ohm Brew Nautical Nostalgia.
• Complex cocktails: Zeus Juice Blue Slush, Doozy Salt & Sour Cherry Cola.

Comparison table: same flavour, both formats

Cost Per Puff: Which Is Cheaper In Reality?

On a per-mg-of-nicotine basis, freebase in shortfill format is meaningfully cheaper than nic salt in 10ml bottles. On a per-hour-of-satisfaction basis, however, nic salt often wins because the faster absorption means users vape less to feel satisfied. The October 2026 HMRC vape excise duty of £2.20 per 10ml will substantially reshape this maths.

Real-world 2026 pricing

Read carefully: nic salt is actually cheaper per mg of delivered nicotine. The freebase myth of "cheap juice" only holds if you compare bottle volume, not nicotine delivered. Because most freebase users vape at 3mg, they burn through juice fast to get satisfied. Real-world weekly cost for both formats lands very close to £15-£20 for the average vaper.

What the HMRC vape excise duty means from October 2026

The UK Government confirmed at the Autumn Statement 2024 that a new vape excise duty comes into effect 1 October 2026 at £2.20 per 10ml of e-liquid, plus a matching £2.20 per 10ml one-off increase in tobacco duty to maintain the smoking-vs-vaping harm reduction incentive. Full details on gov.uk. Practical impact:

• A 10ml nic salt bottle currently £3.99 rises to roughly £6.19.
• A 100ml shortfill currently £14.99 rises to roughly £37 (dutied on the whole 100ml because it counts as a vape product).
• Nic shots (10ml each) rise by £2.20 each.
• Net effect: nic salt in 10ml bottles becomes proportionally cheaper vs shortfills. Expect market share to shift further toward salts.

UK Regulation: What The Law Says In 2026

UK vape products are regulated under the Tobacco and Related Products Regulations 2016 (TRPR), enforced by the Medicines and Healthcare products Regulatory Agency (MHRA) and Trading Standards. The core rules apply equally to nic salts and freebase.

Key UK vape rules that apply to both formats

• Maximum nicotine strength: 20mg/ml.
• Maximum bottle size for nicotine-containing e-liquid: 10ml.
• Maximum tank capacity for refillable vapes: 2ml.
• All e-liquids must be MHRA-notified before sale — search the MHRA product register.
• Child-resistant, tamper-evident packaging is mandatory.
• Warning label: "This product contains nicotine which is a highly addictive substance."
• Legal age of purchase: 18+. Enforced by Trading Standards, penalty up to £2,500 per offence.

The June 2025 disposable ban

Under the Environmental Protection (Single-use Vapes) (England) Regulations 2024 and equivalent devolved legislation in Scotland, Wales and Northern Ireland, the sale of single-use disposable vapes became unlawful across the UK from 1 June 2025. This was an environmental policy, not a health one — the concern was 5 million disposables being binned each week (Material Focus, 2024). Refillable pod kits running nic salt were not affected, which is why the market pivoted cleanly to the format.

The Tobacco and Vapes Bill 2025-26

The Tobacco and Vapes Bill, currently progressing through Parliament, introduces further restrictions expected in force through 2026-27:

• Restrictions on flavour descriptors and marketing (details under consultation).
• Plain packaging requirements for e-liquids.
• Age restrictions on display and location of vape products at retail.
• Ban on free samples and vending machine sales.

None of this affects the underlying legality of either nic salt or freebase — both remain fully legal for adult purchase in the UK. See the full Bill on bills.parliament.uk.

Health Considerations: What NHS And MHRA Say

Both nic salt and freebase e-liquids sit under the same public health assessment: vaping is substantially less harmful than smoking but not risk-free, and non-smokers and children should not vape. This is the consistent line from NHS, the Office for Health Improvement and Disparities (OHID), and the King's College London 2022 evidence review commissioned by government.

The NHS position

NHS Better Health guidance states plainly that "using an e-cigarette can help you manage your nicotine cravings" and "nicotine itself is not very harmful and has been used safely for many years in medicines to help people stop smoking." Full guidance at nhs.uk/better-health/quit-smoking. The NHS does not distinguish between nic salt and freebase in its cessation advice — both are accepted forms.

What Public Health England said

The frequently cited "95% less harmful than smoking" figure originated from a Public Health England evidence review in 2015 and has been broadly upheld in subsequent OHID reviews. This applies equally to both nic salts and freebase.

Is nic salt "worse" because it absorbs faster?

There is no evidence that nic salt is more addictive or more harmful than freebase in itself. The concern raised by some researchers is that the smoothness makes very high-strength consumption easier, which could lead heavy users to consume more total nicotine. Set against that: the smoothness is also what makes nic salt effective at getting smokers off tobacco, which remains the single biggest preventable cause of death in the UK. The Office for National Statistics reports approximately 74,600 UK smoking-attributable deaths per year (ons.gov.uk).

What to avoid regardless of format

• Non-MHRA-notified imports (grey market, no batch testing).
• Anything sold as "50mg" or "60mg" — illegal in the UK, likely unregulated.
• Refilled disposable pods with a substance other than the one they were designed for.
• DIY nic salt mixing without accurate scales — benzoic acid dosing errors can create genuinely harsh product.

Nic Salt vs Nicotine Pouches: The Modern Cross-Category

Since 2023, UK adults switching from smoking have increasingly split their nicotine intake between vaping (both formats) and tobacco-free nicotine pouches like Zyn, Velo and Nordic Spirit. Nicotine pouches use pharmaceutical-grade nicotine in a paper sachet placed under the lip. Because they are tobacco-free, they are not restricted under the TPD — currently there is no UK cap on nicotine strength in pouches, though the Tobacco and Vapes Bill will introduce one.

How pouches compare to nic salt vaping

Many UK vapers now use nic salts in the day and nicotine pouches in situations where vaping is impractical (flights, offices, restaurants). Full pouch range at /nicotine-pouches.

Common Mistakes When Switching Between Nic Salt And Freebase

The biggest mistakes UK vapers make are using the wrong strength for their hardware and expecting the same experience across formats. Here is what goes wrong most often and how to avoid it.

Mistake 1: Putting 20mg nic salt in a sub-ohm tank

At 60W in a 0.2ohm mesh coil, a 20mg nic salt e-liquid delivers roughly 4-5x the intended nicotine dose per puff. Users report nausea, dizziness, headache and rapid heart rate. Never do this. Salt goes in pods, freebase goes in tanks.

Mistake 2: Using 3mg freebase in a small pod

Not dangerous, just useless. The pod cannot vaporise enough juice to deliver a satisfying nicotine dose at 3mg. Users chain-vape trying to get satisfied and end up more frustrated than when they started. Match strength to hardware.

Mistake 3: Buying 200ml shortfills to save money then failing to add nic shots

Shortfills are 0mg base. Without the nic shot, you are inhaling flavoured vegetable glycerin. This has no cessation value if you are trying to quit smoking. Always add the correct number of shots for your target strength.

Mistake 4: Believing "smooth salt" marketing over TPD-notified product

Some grey market e-liquids market themselves as "smooth salt" or "ice salt" outside the MHRA register. If it is not on the MHRA product database, do not buy it. UK Trading Standards will confiscate stock, and consumers have no batch-testing guarantee.

Mistake 5: Chasing progressively higher strengths

UK law caps at 20mg. If 20mg does not satisfy you, the answer is not "find something stronger" — it is either better hardware (more efficient mesh coil, longer draw), more frequent puffs (a pod with bigger battery), or supplementing with a nicotine pouch for on-demand top-ups.

Nic Salt vs Freebase for Ex-Disposable Users

The single biggest UK vaper group in 2026 is the 5-6 million adults who used to run disposables and now use big-puff refillable pods after the June 2025 ban. Every one of these devices uses 20mg nic salt — because the format was purpose-built for pods. If you were an Elf Bar 600 or Lost Mary BM6000 user, nic salt is not a choice, it is the format you were already using.

Direct disposable-to-refillable swaps

These are like-for-like swaps — same flavour range, same 20mg nic salt, same hit — just refillable and legal. The typical UK price for the kit lands between £8.99 and £12.99, with replacement pods £3-£5. Weekly running cost is meaningfully cheaper than disposables were.

Why big-puff refillables changed the maths

A Hayati Pro Ultra 25K at £10.99 with a £3.99 refill pod delivers roughly the same volume as 40 Elf Bar 600s (which would have cost £200). The regulatory arbitrage of "refillable" instead of "disposable" made the format cheaper, greener and identical in user experience.

Nic Salt vs Freebase: How To Try Both Cheaply

The smart approach for anyone unsure is to try both without a big hardware investment. A £20 pod kit runs nic salt. A £30 sub-ohm starter runs freebase. Together, £50 tests both formats across a fortnight.

The £50 dual-format test kit

• Vaporesso XROS 4 pod kit — £19.99 — runs 20mg nic salt.
• Vaporesso Target 100 sub-ohm kit — £29.99 — runs 3mg freebase.
• 10ml Elfliq salt 20mg — £3.99.
• 100ml Dinner Lady shortfill + 2 nic shots — £16.99.

Vape each for a week. You will know within days which one suits you. Most ex-smokers land on salt. Most hobbyists land on freebase. Some rotate.

The Verdict: Which Should You Vape In 2026?

For the vast majority of UK adult smokers switching in 2026, nic salt in a refillable pod kit is the correct answer. It replicates the cigarette satisfaction curve, works with the hardware format that dominates the market, is fully legal at 20mg, and remains meaningfully cheaper per mg of delivered nicotine than shortfill freebase. For experienced hobbyist vapers who enjoy sub-ohm cloud production and complex dessert or tobacco flavours, freebase in a 100ml shortfill remains excellent value and the superior flavour vehicle.

18+ Age Warning

You must be 18 or over to buy vape products in the UK. Vape Daily operates Challenge 25 and requires proof of age on delivery. E-liquid contains nicotine, which is a highly addictive substance. Vaping is not suitable for non-smokers, pregnant women or those with underlying respiratory conditions. If you are trying to quit smoking, additional support is available free from NHS Better Health, your GP, or your local stop-smoking service. Keep all vape products out of reach of children and pets — even at 10mg, a 10ml bottle of nicotine e-liquid is a poisoning risk if ingested. In an emergency call 111 or the National Poisons Information Service.

Frequently asked questions

What is the difference between nic salt and freebase e-liquid?

Freebase is the pure alkaline form of nicotine used in traditional e-liquids since 2007. Nic salt is freebase nicotine bonded with an organic acid (usually benzoic acid) which lowers the pH, making it far smoother to inhale at high strengths and letting it absorb into the bloodstream faster. In practice, freebase is best for low-strength sub-ohm cloud vaping, while nic salt is best for high-strength pod and disposable-replacement kits.

Is nic salt smoother than freebase?

Yes, considerably. A 20mg nic salt e-liquid feels roughly as smooth as a 6mg freebase juice. That is because the benzoic acid used in salts lowers the pH from around 8-9 (harsh, alkaline) to 6-7 (near neutral). This is why UK vapers can comfortably use 20mg nic salt in a small MTL pod like the Elf Bar Elfa Pro but cannot tolerate 20mg freebase in the same device.

Do nic salts hit harder than freebase?

At the same strength, nic salts hit harder and faster because they absorb into the bloodstream within about 30 seconds rather than the 2-3 minutes freebase typically takes. This mimics the rapid satisfaction curve of a cigarette. However, at low strengths (3mg-6mg) freebase delivered through a high-wattage sub-ohm coil can produce a bigger physical throat hit because of the volume of vapour and its alkalinity.

Which kit should I use nic salts in?

Use nic salts in low-wattage MTL (mouth-to-lung) pod kits between 8W and 25W with coil resistances of 0.6ohm or higher. Ideal UK 2026 options include the Elf Bar Elfa Pro, Lost Mary Tappo, Uwell Caliburn G3, Vaporesso XROS 4 and OXVA Xlim Pro 2. Avoid using nic salts in sub-ohm cloud kits — the vapour volume delivers dangerously high nicotine doses.

Can I use freebase in a pod kit?

Technically yes, but only at very low strengths (3mg or 6mg) and only in pods designed for higher VG, higher-wattage direct-lung use such as the Uwell Caliburn X or Vaporesso XROS with a 0.4ohm mesh coil. Standard 20mg freebase in a small MTL pod will be unbearably harsh on the throat and is not something any UK retailer would recommend.

Is nic salt better for quitting smoking?

For most adult smokers switching for the first time, yes. NHS smoking cessation advice recognises that vaping is substantially less harmful than smoking, and the rapid, smooth nicotine absorption of a 20mg nic salt pod most closely replicates the satisfaction curve of a cigarette. This is why post-2021 UK stop-smoking services have largely moved from recommending 18mg freebase in tanks to recommending 20mg nic salt in refillable pods.

Why does freebase taste harsh at high strength?

Because freebase nicotine is highly alkaline (pH 8-9). When it hits the delicate tissue at the back of the throat, that alkalinity causes an aggressive burning sensation vapers describe as a 'kick'. At 3mg or 6mg it feels satisfying to experienced vapers, but at 18mg or 20mg it feels like inhaling ammonia. Nic salts neutralise this by lowering the pH with an organic acid.

Are nic salts more expensive than freebase?

Per 10ml bottle they are usually the same price — around £3.99 to £4.99 in the UK. However, cost per mg of nicotine is where freebase wins: a 100ml shortfill of freebase e-liquid at £14.99 works out at roughly 1.5p per mg of nicotine after adding two nic shots, whereas 10ml nic salt bottles land closer to 2.5p per mg. From October 2026 the new HMRC vape excise duty of £2.20 per 10ml will level this gap significantly.
