The Real Cost of Vaping Longfills
The real cost of
vaping longfills
Past the 17p per ml headline sits a fuller picture. Mixer Kits, coils, device replacement, shipping plus the 2026 vape tax. This is the honest UK annual audit covering every line that hits your bank account.
A moderate UK vaper at 4ml per day spends around £320 in the first year (with a new refillable device) and around £300 each year after. The breakdown: £240 on longfill bottles plus Mixer Kits, £60 on replacement coils plus pods, £20 amortised device cost. The 2026 Vaping Products Duty adds roughly £95 more per year from October 2026. Light vapers spend £180 annually. Heavy vapers spend £540. Compared to smoking, it is roughly 1/18th the cost of a pack-a-day habit.
Three yearly totals
for three vaper profiles
Annual spend including everything: liquid, Mixer Kits, coils, shipping plus device amortisation.
Light vaper year
2ml daily pod user. Around £15 per month all-in. One bottle every 3 weeks.
Moderate vaper year
4ml daily MTL user. Around £27 per month all-in. Two bottles per month.
Heavy vaper year
10ml daily sub-ohm user. Around £45 per month all-in. Five bottles per month.
Longfills are cheap. The real question is what adds to the 17p per ml base.
Every longfill article on the internet quotes 17p per millilitre as the headline cost. That figure is accurate if you only buy one bottle plus its matched Mixer Kit. In practice vaping is a subscription habit plus the real cost includes the ancillary purchases most people forget when budgeting. Coils fail. Pods crack. Devices stop charging. Shipping charges apply below minimum order values. Cooling shots get added on impulse. Each of these adds a few pounds per month that compound across a year.
For a moderate UK vaper at 4ml per day (the most common usage profile), the all-in annual cost in 2026 sits at around £320 in year one and around £300 each year afterwards. The difference is the one-off £20 refillable device cost. Once you own the kit, the running cost is roughly £300 per year split between liquid (£240), coils plus pods (£60), plus minor accessories. That works out to £25 per month.
The 2026 Vaping Products Duty will change this from 1 October 2026. The new duty adds £2.64 per 10ml of finished e-liquid including VAT, which means a 60ml longfill bottle attracts £15.84 in new duty. For a moderate vaper buying 24 bottles per year, that represents £380 per year in new duty. The practical impact: post-duty annual cost for a moderate vaper rises to around £680 per year total (from the current £300). The duty is paid regardless of which e-liquid format you pick, so longfills remain the cheapest format per ml even after the duty applies.
Where every pound of your longfill budget goes
The liquid itself accounts for about 75 percent of an annual longfill budget. Coils plus pod replacements account for another 15 percent. The refillable device (amortised across year one) accounts for 5 percent. Shipping plus accessories make up the remaining 5 percent. From October 2026 the new duty flips this dramatically, becoming the single largest line item at nearly 55 percent of annual spend. Nothing else really competes with how much the tax changes the picture.
The good news: smart shopping habits save roughly £60 per year for a moderate vaper. Hitting the multi-buy deals. Consolidating orders to avoid shipping. Buying decent refillable kit that lasts 12 months plus rather than cheap kits that fail. Sticking to one longfill brand so the Mixer Kits can be bulk-ordered together. These tactics drop an annual £300 spend to roughly £240, which is more like £20 per month for the same vape experience.

Four costs most longfill
vapers forget about
Ancillary spend that slips through the cracks
The Mixer Kit reminder
New longfill buyers often order a bottle plus forget the Mixer Kit. The concentrate alone is not vapeable. Always buy both together or check the product page bundle options.
Risk: re-shipping £3-4Coil replacement cycles
Coils need replacing every 2 weeks for most regular vapers. That is 26 coils per year at roughly £1 each. Not huge but easy to miss when budgeting around the liquid.
£26 per year missedPod and tank cracks
Refillable pods or tanks get dropped, stressed or cracked. Most need replacing every 6 months at around £6 each. Not frequent but real.
£12 per year missedBelow-threshold shipping
Most UK vape retailers offer free delivery at £25 plus. Small one-off orders under that amount attract £3-4 shipping. Consolidating orders saves roughly £20 per year.

From 1 October 2026: add the Vaping Products Duty of £15.84 per 60ml bottle. For 24 bottles that is £380 per year extra, taking the post-tax annual total to approximately £700.
