Buying your first device: a no-nonsense guide

Since disposables were banned in June 2025, most adults switching from smoking start with either a closed pod system or a refillable open tank. Neither is objectively "better" — they suit different habits and budgets.

Pod system vs. refillable tank

Closed pod systems use pre-filled or easy-fill cartridges. They cost more per ml but need no maintenance, which suits anyone who wants something closer to disposable simplicity. Refillable tanks cost less to run over time and let you choose any e-liquid, but need occasional coil changes and a bit more hands-on care.

As a rough rule: if you're switching from smoking and want the lowest possible friction, start with a pod system. If you already know you'll vape regularly for months, a tank pays for itself within a few weeks.

Nicotine strength, in plain terms

UK e-liquid is capped at 20mg/ml. As a starting point, people who smoked a pack a day typically start around 12–20mg/ml in a pod system, or lower — 3–6mg/ml — in a higher-output tank, since tanks deliver more vapour per puff at the same strength. If you're coughing or finding it harsh, the strength is usually too high, not too low.

Real running costs

Budget roughly £15–£25 for a starter pod kit and £3–£4 per week in refills for light use. Tank setups cost more upfront (£25–£40) but coils and liquid typically run cheaper per ml once the Vaping Products Duty is factored in from October 2026.

What to check before you buy

Look for CE/UKCA marking, a UK-based retailer with clear age verification at checkout, and a return policy that covers faulty devices. Avoid marketplace listings with no verifiable UK seller — counterfeit coils and batteries are a real safety issue, not just a trust one.
