Will Vaping Still Be Cheaper Than Smoking After the 2026 Duty?

The introduction of the UK’s 2026 vaping duty has raised an obvious question for adult smokers and vapers: will vaping still be cheaper than smoking once the new tax is added? The short answer is that vaping is still likely to remain cheaper for many regular users, but the gap may become smaller depending on the products they buy, how frequently they vape, and whether they use refillable or prefilled systems.

The new duty changes the economics of vaping, particularly for users who regularly buy bottled liquids or higher-capacity products. However, cigarette prices remain heavily affected by tobacco duty, meaning smoking continues to carry a high ongoing cost.

What Is Changing With the 2026 Vape Duty?

The UK government announced a dedicated tax on vaping products as part of a broader change to how nicotine products are taxed. The new duty is designed to apply to vaping liquid rather than the device itself, meaning products containing liquid may become more expensive once the tax is included.

The final retail impact will depend on how manufacturers and retailers pass the duty through to customers. Some may absorb part of the increase, while others may add most or all of it to the final selling price.

For shoppers using Vapekituk, the practical effect will likely be most noticeable when comparing the price of liquids, pod refills, and high-capacity products before and after the duty takes effect.

Will E-Liquid Become More Expensive?

Yes, that is the most likely outcome.

Because the duty applies to vaping liquid, bottled E-liquids are expected to increase in price once the tax is reflected at retail level. The exact amount will depend on bottle size, duty treatment, VAT, and retailer pricing.

For regular users, this means the cost of a 10ml bottle, shortfill, or refill product could rise compared with current prices.

However, the important comparison is not simply whether vaping gets more expensive. The real question is whether it becomes more expensive than smoking, and that depends on how much someone currently spends on cigarettes versus their chosen vape setup.

Smoking Is Also Subject to Heavy Taxation

Cigarettes already carry substantial tobacco duties in the UK, and tobacco taxation has historically been used to keep cigarette prices high.

That means even if vaping products become more expensive after the 2026 duty, smoking will still start from a much higher cost base for many users.

A smoker buying cigarettes every day can spend significantly more over a month than someone using a refillable pod system and purchasing liquid separately.

The difference may narrow after the duty, but it is unlikely to disappear completely for most users unless their vaping habits involve particularly expensive high-capacity or premium products.

Refillable Vaping May Still Offer the Best Value

Refillable pod systems are likely to remain one of the more economical ways to vape.

Once the initial device has been purchased, the main ongoing expenses are replacement pods or coils and liquid. Even after a new duty increases liquid prices, users are not replacing the complete device every time the liquid runs out.

This can make refillable systems especially attractive for regular adult vapers who want to keep ongoing costs under control.

Users who vape frequently may therefore find that moving toward refillable hardware becomes even more financially attractive after the duty is introduced.

What About Prefilled Vape Kits?

The effect may feel different for people using Preffiled vape kits because the liquid is already contained within the pod or refill component.

Manufacturers and retailers may incorporate the additional duty into the complete product price, making individual kits or replacement pods more expensive.

Higher-capacity systems could still offer reasonable value when measured against how much liquid they contain, but shoppers will need to compare total cost rather than focusing only on advertised puff counts.

A larger puff figure does not automatically mean better value if the device itself carries a significantly higher post-duty price.

Nicotine Strength Does Not Necessarily Mean Higher Cost

The new duty structure is primarily concerned with vaping liquid, rather than simply charging more because a product contains stronger nicotine.

That means users of Nic salt products should focus more on bottle or pod capacity than on assuming that a stronger nicotine level will automatically cost more.

For many mouth-to-lung users, a smaller amount of higher-strength liquid may last longer than a larger amount used in a high-powered device.

This is another reason why individual vaping style matters when comparing post-duty costs.

Refillable vs Prefilled After the Duty

After the duty takes effect, the difference between refillable and prefilled systems may become more important.

Refillable users generally buy liquid separately and reuse the same device, while prefilled users purchase pods or kits containing both liquid and hardware components.

A refillable pod device may require a slightly higher initial investment, but ongoing costs can remain lower because the hardware is reused.

Prefilled systems remain convenient, but that convenience may carry a higher long-term cost, especially if duty increases the price of every replacement pod or liquid-containing component.

Will High-Capacity Vapes Still Be Good Value?

High-capacity vape products may still provide good value, but shoppers will need to look more carefully at the true cost per amount of liquid rather than the headline puff number.

If duty is applied according to liquid volume, products containing more liquid will naturally attract more tax than smaller-capacity products.

That does not automatically make them poor value. A larger device may still last substantially longer than several smaller ones.

The important calculation is how much usable vaping time you receive for the final retail price.

Could the Duty Encourage More People to Use Refillable Kits?

It is possible.

If the price of prefilled products rises more noticeably, some users may move toward refillable pod systems to reduce ongoing costs.

Refillable vaping gives users more control over liquid choice, nicotine strength, pod resistance, and how much liquid they buy at one time.

This could make refillable devices increasingly attractive to cost-conscious adult vapers, particularly those who vape every day and therefore feel even small price increases over the course of a month.

How Much Could a Regular Vaper Spend?

There is no single figure because vaping habits vary widely.

Someone using a low-powered pod kit may consume relatively little liquid each week, while a user with a high-powered sub-ohm device can go through much larger quantities.

Similarly, someone using high-capacity prefilled products will have different costs from a person buying bottled liquid and replacement coils.

The most useful approach is to calculate your current monthly vaping spend and then estimate how much an increase in liquid prices would add.

That gives a more realistic comparison than simply looking at the price of one bottle or device.

Will Vaping Still Be Cheaper Than Smoking?

For many regular adult users, probably yes, particularly when using a refillable pod system.

Smoking remains expensive because cigarettes are already subject to high tobacco taxation. Even with additional duty on vaping products, a refillable vape can still involve lower monthly running costs than purchasing cigarettes every day.

However, the savings may become smaller.

Users who buy premium prefilled devices, consume large amounts of liquid, or replace hardware frequently may notice a bigger increase in their monthly spending than light or moderate refillable users.

How to Keep Vaping Costs Lower After the Duty

The easiest way to manage costs is to focus on the overall running expense rather than individual product prices.

A reliable refillable pod device can reduce the need to keep purchasing complete devices. Choosing suitable coils, avoiding unnecessary liquid waste, and replacing pods only when performance genuinely declines can also help.

Comparing the cost per millilitre of liquid can be more useful than comparing puff claims because puff counts vary considerably between users.

Buying the right device for your actual vaping style is likely to matter even more once the duty is introduced.

Final Thoughts

The 2026 vaping duty is expected to make vaping products more expensive in the UK, particularly products containing larger quantities of liquid. However, that does not necessarily mean vaping will become more expensive than smoking.

For many adult smokers who switch completely to a refillable vape, the ongoing cost is still likely to remain lower than buying cigarettes regularly. Prefilled and high-capacity products may see a more noticeable increase, while refillable pod systems could become increasingly attractive from a cost perspective.

The key change is that users will need to compare products more carefully. Instead of looking only at the price of a device or its advertised puff count, consider liquid capacity, replacement costs, and total monthly spending.

Note: Tax rates and implementation details can change. Check the latest HMRC guidance and retailer pricing when the 2026 duty takes effect.

Important: Vape products are intended only for adults aged 18 or over who already smoke or vape. Products containing nicotine are addictive.
