Cost of running an IVG Pro 12 for a year: the real numbers

If you're here, you've already settled the cigarettes-versus-vape question (we covered that on the ex-smokers page) and what you actually want now is the granular running-cost number for the Pro 12 specifically. How many refill packs across a year, how often the battery body needs replacing, what the cable adds, what the new October 2026 vape duty does to all of this. This is the page for that, with the assumptions shown openly so you can scale them up or down based on your own usage.

The headline number for the typical 15-to-20-a-day user is around £225 for the first calendar year at current 2026 prices. That covers the initial kit (£10.95), one USB-C cable purchased once (£2.99), roughly 43 refill packs across the year (£214 at £4.99 each, slightly less than 52 because most users skip a few weeks across holidays or sickness), and a fractional charge for the device-body replacement after roughly 12 to 18 months. After October 2026 the new vape duty bumps this to roughly £330; the maths for that is in the duty-impact section below.

Three caveats up front. Light users get away with less, around £130 per year, because they buy refill packs every 10-14 days rather than every 7. Heavy users (30+ a day) push above £400, mostly because they need 70+ refill packs annually. The "year" we're costing is a calendar year, not a precise 365-day cycle from your purchase date; if you buy in mid-December, the duty arrival in October still counts as the same calendar year for these purposes.

Reading the curve

Two things to notice. Most months add a similar amount (roughly £15-18) because the typical user buys one refill pack per week at £4.99, plus an occasional second pack in heavier weeks. The first month is slightly higher because of the initial kit purchase and USB-C cable; the curve flattens to a steady slope from February onwards. The October step is the vape duty kicking in, adding roughly £2.20 per refill pack from that point onwards. The slope becomes steeper for the last three months.

If you bought the kit in (say) March, your year-1 curve would shift two months to the right and the post-duty steeper segment would be longer; the total annual figure stays around £225 in the pre-duty world but climbs to about £330 in a full post-duty year. That's the figure most ex-smokers should mentally hold for 2027 onwards: roughly twenty-eight pounds a month, give or take.

"The cumulative-cost curve looks dramatic in a chart but it's a slow steady drip in real life. Most months you're buying one refill pack at the counter and not thinking about it. The annual figure only registers when you sit down to add it up."

Three observations from the breakdown. Refills dominate the line items: at £215 of £235 annually, they're 91% of the total cost. The device body, cable, and battery replacement combined are under 10%. This means the refill pack price is the variable that matters most to your annual spend; if you're buying refills at £6.99 elsewhere instead of £4.99 at us, your annual cost climbs by £86 to £320.

The cable is borderline-optional. If you already have a USB-C cable from a phone or laptop, you can skip the £2.99 line entirely. Most counter customers do skip this, which is why we mark it as £2.99 or zero in the table. The battery-body replacement is annualised across the device's lifetime: a single £10.95 spend every 18 months works out to £7.30 per year on average, even though the actual cash leaves your wallet only once.

Where you can sensibly cut costs

Three approaches. Multibuy refill deals: 3 refill packs for £13 (instead of £14.97 at single price) saves you about £17 per year if you stick to the offers. Skip the cable purchase using an existing one (saves £2.99 once). Stretch refill packs through lower nicotine: tapering down to 10mg or 0mg (the same packs in lower strengths) doesn't affect cost but reduces nicotine intake; this is more about long-term harm reduction than savings.

The approach we don't recommend: buying very cheap refill packs from non-authorised retailers. Sub-£3.99 IVG Pro 12 refills from anywhere other than recognised UK retailers are likely to be expired stock, parallel-imported (no UK warranty), or counterfeit. The roughly £1 per pack saving works out to maybe £50 per year, but the risk of getting bad refills is real. Stick to authorised stockists.

What the duty actually changes for you

For the typical Pro 12 user the duty bumps the per-refill price from £4.99 to roughly £7.49 once retailers pass the duty through to consumers. Annual cost climbs from £225 to roughly £330, which is an extra £105 per year or about £9 per month. That's noticeable but not dramatic; even with the duty, the Pro 12 remains roughly 17 times cheaper than smoking 20 a day.

The other thing to know: the duty applies to all e-liquids regardless of nicotine strength, including the 0mg refill packs. People sometimes assume zero-nicotine vaping will be exempt; it isn't. The duty is on the e-liquid itself, not on the nicotine. The good news, such as it is, is that pricing across all strengths goes up uniformly so there's no penalty for picking lower-strength packs.

Three years out: what to budget

Looking forward, here's a rough multi-year budget assuming consistent typical use. Year 1 (2026, partial duty): ~£245. The current calendar year if you've started recently. Year 2 (2027, full duty): ~£330. The first complete post-duty year. Year 3 (2028 onwards): ~£330 plus inflation. Adjust upwards a few percent annually for general price rises.

Three-year total: roughly £900-950. That's still a fraction of the £17,000 that three years of pack-a-day cigarettes would cost, but it's enough money to budget for rather than ignore. Most ex-smokers we talk to find the comparison reframes the question entirely; vape costs feel small next to cigarette costs but only when you actually do the maths.

The short version

• Year 1 typical cost: ~£225 pre-duty, ~£330 post-duty.
• Refills are 91% of running cost; everything else is rounding.
• Vape duty starts 1 October 2026 at £2.20/10ml.
• Per-refill price after duty: ~£7.49 instead of £4.99.
• Light user: ~£130/year. Heavy user: ~£400+/year.
• Three-year typical total: ~£900-950 including duty.
• Cigarette comparison still wins: ~£5,400 saved per year for 20-a-day ex-smokers.
