E-liquid tax: what changes in the UK in 2026

For years the fiscal treatment of vaping liquid in Britain was a matter of speculation, revisited at every Budget and settled at none of them. That period is over. The e-liquid tax now has a name, a legal basis, a commencement date and a scope defined in published guidance.

What follows is the factual position as set out by HM Revenue and Customs, without the estimates and rumours that circulate around it. It covers what the duty applies to, when it starts, how it is calculated and which products fall inside its scope, including several that many people assume are outside it.

Is there an e-liquid tax in the United Kingdom?

There is now, and it is new. Vaping Products Duty is an excise duty introduced by HMRC that takes effect from 1 October 2026, with registrations for businesses opening on 1 April 2026.

Until that date there is no excise duty on vaping products in Britain. Liquid is sold subject to VAT in the ordinary way, as most consumer goods are, and the new duty adds a separate charge rather than replacing anything.

The measure was announced at Spring Budget 2024 and confirmed at Autumn Budget 2024, with a consultation on its design in between. Primary legislation sits in the Finance Bill 2025-26, and HMRC anticipated secondary legislation in March 2026 to set out the remaining detail.

What the duty actually applies to

The scope is deliberately wide, and this is where most assumptions turn out to be wrong. The duty applies to vaping liquid containing nicotine together with either or both of glycerine and glycol, and to any liquid intended to be vapourised by a vape that is not a medicinal or tobacco product.

Read carefully, that second limb does the heavy lifting. Nicotine is not a condition of liability. Liquid with no nicotine in it, which in Britain covers the entire shortfill category, is inside the scope, as our guide to a nicotine free vape notes.

The same reasoning captures other formats sold in vape shops. A CBD e-liquid intended to be vapourised is not a medicinal or tobacco product, so it too falls within the definition. The duty is charged on products produced in, or imported into, the United Kingdom.

How the e-liquid tax is calculated

The basis is volume rather than value or strength. HMRC applies a flat rate per ten millilitres of vaping liquid, regardless of how much nicotine the product contains, and that single design choice explains most of the consequences that follow.

An earlier proposal set out tiered rates that varied with nicotine strength. Following consultation feedback, that structure was replaced with the flat rate, which HMRC says aligns with most international counterparts and simplifies calculation, reporting and compliance, while reducing disputes over how a product should be classified.

A charge based on volume falls on people according to how much liquid they get through rather than what they pay for it. HMRC states that the measure affects an estimated 5.1 million people who vape in the United Kingdom, and that heavier users face the highest burden under it.

VAT continues to apply in the normal way. The duty is an additional charge that sits alongside the existing tax rather than absorbing it.

One consequence of the flat rate is worth spelling out, because it inverts an assumption many people hold. Since the charge follows volume alone, a large bottle of low strength liquid attracts more duty than a small bottle of high strength liquid, which is the opposite of how a strength based tier would have worked.

HMRC has also been explicit that whether businesses pass the cost on or absorb it is a commercial decision rather than something the legislation determines. Any figure circulating about what a given bottle will cost after October is therefore a forecast about retailer behaviour, not a statement of what the duty requires.

Duty stamps and the compliance machinery

The duty does not arrive alone. It comes with a Vaping Duty Stamps scheme, and HMRC has said the combined effect of the two is expected to be significant for businesses.

Vaping Products Duty becomes part of the existing excise regime established by the Customs and Excise Management Act 1979, with amendments giving HMRC officers enforcement powers. Manufacturers, importers, warehousekeepers and distributors take on registration and monthly return obligations.

Enforcement follows the pattern of other excise duties. There are civil penalties for failing to register, failing to file returns and failing to pay, and the legislation introduces criminal offences carrying possible custodial sentences for non-compliance, alongside the existing offences covering excise evasion.

For anyone buying, the practical marker is the stamp. From the point the scheme applies, a compliant pack on a British shelf looks different from a non-compliant one, which makes it a far more useful check than anything printed in a product description. Our guide to buying e-liquid refills covers the other markers worth applying.

The wider regulatory picture around the e-liquid tax

The duty is one of several changes landing in close succession, and reading it in isolation gives a misleading impression of how much is moving at once.

The single use vapes ban took effect on 1 June 2025, making it illegal to sell or supply disposable devices anywhere in the United Kingdom whether or not they contain nicotine. That reshaped the market before the duty was even legislated for, shifting purchasing towards refillable hardware and therefore towards recurring liquid purchases.

The Tobacco and Vapes Act received Royal Assent on 29 April 2026. It includes measures banning the advertising and sponsorship of vapes and nicotine products, powers to restrict their packaging, branding and displays, stronger enforcement powers and the ability to implement a retail licensing scheme.

Layered on top of the existing product rules, the picture is now dense. Capacity capped at 2 ml, nicotine strength capped at 20 mg per ml, nicotine containing refill containers capped at 10 ml, MHRA notification before sale, an age of sale of 18, a disposables ban, an advertising ban, and from October 2026 an excise duty with its own stamps scheme.

Frequently asked questions

When does Vaping Products Duty start?

The duty takes effect from 1 October 2026. Business registrations opened on 1 April 2026, and secondary legislation setting out further detail was anticipated in March 2026.

Does the duty depend on nicotine strength?

No. It is charged at a flat rate per ten millilitres of liquid regardless of nicotine content, after an earlier tiered structure was dropped following consultation.

Does it apply to nicotine free liquid?

Yes. The definition covers any liquid intended to be vapourised by a vape that is not a medicinal or tobacco product, which includes shortfills and other 0mg formats.

Is this instead of VAT?

No. VAT continues to apply as it does to other consumer goods. The duty is an additional excise charge that sits alongside it rather than replacing it.

What are duty stamps for?

They are part of a separate Vaping Duty Stamps scheme accompanying the duty. For a buyer they are the visible marker distinguishing a compliant pack from one that has bypassed the regime.

What it means in practice

The years of conditional reporting are behind us. The measure exists, its scope is published, its start date is fixed and its basis of calculation is settled, which makes planning around it a matter of arithmetic rather than speculation.

Three points are worth carrying forward. The charge follows volume, so consumption rather than spending determines the burden. The scope is defined by what the liquid is for rather than what is in it, which pulls nicotine free and CBD formats inside. And the duty stamps scheme gives buyers something concrete to look for on a pack.

Everything else, including how much of the charge sellers pass on, is a commercial decision rather than a legislative one, and HMRC has explicitly said as much. Following the published guidance rather than the noise around it remains the only reliable way to track the e-liquid tax, and with the commencement date now in sight the e-liquid tax has moved from something to speculate about to something to read carefully.
