BNPL boom in 2026: How UK 18–34s are using instalments to shift from disposables to reusable vape kits

Introduction

The UK’s payments landscape has changed rapidly. By early 2026 more than half (54%) of adults have tried Buy‑Now‑Pay‑Later (BNPL), and the service has become a natural fit for younger shoppers upgrading to reusable vape hardware after the June 2025 disposable ban. This trend matters for retailers, regulators and vapers alike: it reshapes purchase behaviour, raises order values and brings fresh regulatory scrutiny. Here we explain what's trending, why it matters, give real examples of emerging patterns and look ahead to what comes next.

What's trending

BNPL is no longer a niche payment option. Recent industry summaries show Millennials and Gen Z together account for roughly 65% of BNPL users, with particularly high uptake among 18–34‑year‑olds (EMARKETER / Statista, Jan 2026). Finder’s early‑2026 data indicates 54% of UK adults have used BNPL at least once, while the average BNPL purchase in the UK sits at around £114, and per‑user BNPL spend continues to rise year‑on‑year.

At the same time, vaping in the UK has undergone a structural change. The government’s June 2025 ban on single‑use disposable vapes accelerated migration to reusable prefilled pod kits and refill pods. Industry reports show that roughly six months after the ban, about 90% of daily adult vapers were using reusable devices (Tobacco Insider, Feb 2026).

Why it matters

The convergence of these two movements—higher BNPL adoption among younger cohorts and a market shift away from disposables—creates a clear commercial opportunity and a consumer challenge.

• Affordability and upfront cost: Reusable kits and premium devices have higher initial prices than disposables. With average BNPL transactions near £114, instalments make these purchases feel affordable for younger buyers who prefer spreading costs.
• Retail economics: Payments industry analysis (Chargeflow) shows merchants adding BNPL often see average order values rise by 20–40% and improved checkout conversion—important for vape retailers stocking higher‑value starter kits and accessory bundles.
• Behavioural fit: 18–34s already dominate BNPL use; they are comfortable with app‑driven finance, and they value convenience. BNPL fits neatly at the point where a customer decides to replace a run of cheap disposables with a reusable pod system and a supply of e‑liquid refills.
• Regulatory context: BNPL entered a sharper regulatory focus in 2026, with plans for FCA supervision and tighter consumer‑protection rules (Finextra). That will affect providers and merchants, influencing how instalments are displayed, advertised and underwritten.

Examples of emerging patterns

We’re seeing a number of concrete behaviours emerge across UK retailers and consumers.

• Bundled purchases financed by BNPL: Younger vapers are buying a reusable kit plus spare pods and a couple of refill shortfills in a single checkout using BNPL to spread the cost. This increases initial spend but reduces long‑term cost per vape compared to disposables.
• Premium upgrades rather than repeat disposables: Rather than repeatedly buying low‑cost disposables, many 18–34s are choosing mid‑range pod kits with better flavour fidelity and longevity—helped by the ability to pay in instalments.
• Large single transactions near the BNPL average: The typical BNPL ticket (around £114) aligns with the price of higher‑end starter kits plus a couple of e‑liquid shortfills or nicotine shot bundles—making BNPL a practical payment method for a one‑stop replacement purchase.
• Cross‑category purchases: BNPL is also being used to buy accessory bundles—chargers, replacement coils and several bottles of shortfill e‑liquid—turning single purchases into higher‑value baskets that benefit merchants.

On the product side, shoppers who migrate to reusable devices often stock up on refills and flavour options. For example, shoppers commonly pair a new kit with 100ml shortfill e‑liquids such as Fantasi 100ml Shortfill or larger 120ml blends like Bar Liq 120ml Shortfill, sometimes combined with longfill/salt options such as Crystalize Bar Salts 120ml Longfill to create a complete starter bundle at checkout.

Merchant response

Retailers have adapted quickly. Many vape shops and online merchants have integrated BNPL options at checkout and promote instalments during product pages for reusable kits. The rationale is straightforward: higher conversion and AOV, balanced against fees and the need to comply with incoming BNPL regulation.

Future outlook: what to expect in 2026 and beyond

Several developments will shape how this trend evolves:

• Tighter BNPL rules: FCA supervision will bring clearer affordability checks and advertising rules. Merchants will need to ensure transparent messaging around instalments and consider whether to absorb fees or pass them to consumers.
• Product education at purchase: Vapers new to reusable devices will benefit from better education in product pages and checkout—explaining lifetime cost savings of refill systems versus disposables, and offering bundles that make the transition straightforward.
• More targeted offers for younger buyers: Expect segmented BNPL offers and marketing that target 18–34s, emphasising instalment convenience, starter bundles and savings over time.
• Marketplace shifts: As more daily vapers use reusable devices (the industry figure near 90%), demand for quality refill e‑liquids, coils and pod accessories will grow. Retailers who pair clear BNPL options with product education will likely capture higher lifetime value customers.

Conclusion

The BNPL boom among UK 18–34s is more than a payment fad; it's a structural enabler for the post‑disposable vape market. As disposables exit stage left following the 2025 ban, younger vapers are opting for reusable hardware that requires a larger upfront spend—exactly the scenario where BNPL fits. For retailers the opportunity is clear: well‑implemented instalments increase order value and help customers transition to better devices, but they must be offered responsibly as regulation tightens in 2026. For consumers, BNPL can make higher‑quality reusable vaping more accessible—provided they use instalments wisely and understand total costs over time.

Whether you're a retailer planning checkout options, a vaper comparing kits, or simply watching market shifts, the intersection of BNPL and reusable vape adoption is one of 2026’s most important trends in the vaping ecosystem.
