How JUSTVAPE 100ml E-Liquid Saves Money Compared to Smaller Bottles
The maths on a 100ml shortfill vs twelve 10ml bottles is more dramatic than most vapers realise. Here is what JUSTVAPE 100ml actually costs per ml, per month and per year, plus what changes when the October 2026 vape tax lands.
JUSTVAPE 100ml + 2 nic shots = ~10p per ml. A typical 10ml bottle = ~35p per ml.
Same e-liquid, same final strength, 70% cheaper. Most heavy vapers save £700 to £950 a year by switching to the 100ml format.

UK-made 100ml 50/50 shortfill e-liquid at pre-duty pricing through 30 September 2026. After 1 October the £2.20 per 10ml Vaping Products Duty adds roughly £22 to every 100ml shortfill. In store in Omagh and Strabane or free UK delivery on orders over £50.
The maths every UK vaper should run before reordering
Most vapers reorder out of habit. A few 10ml bottles drop into the basket every week or two, the card gets tapped and that’s that. What gets missed is the difference between what 10ml bottles cost per ml and what a 100ml shortfill plus nic shots costs per ml of the exact same finished e-liquid. The gap is bigger than most people expect.
The basic comparison at 3mg final strength
JUSTVAPE 100ml shortfill at around £10, plus two 18mg freebase nic shots at around £1 each, gives you 120ml of 3mg e-liquid for roughly £12. That works out to 10p per ml. Twelve separate 10ml bottles at a typical UK retail price of £3.50 each gives you the same 120ml total volume at the same 3mg strength for £42. That works out to 35p per ml. Same e-liquid, same strength, three and a half times the cost.
What that means over a year
A typical UK vaper uses around 3 to 5ml of e-liquid per day, which adds up to roughly 1,500ml a year for a moderate user or 1,800ml a year for a heavy user. On 10ml bottles at 35p per ml, that’s £525 to £630 a year for a moderate user, or £700 to £900 a year for a heavy user. Switch the same habit to JUSTVAPE 100ml plus nic shots at 10p per ml and you spend £150 to £180 a year as a moderate user, or £180 to £210 as a heavy user. The annual saving is £375 to £700 depending on usage.
The flavour is identical
This is the part that surprises new shortfill buyers. The base e-liquid in a 100ml shortfill is exactly the same blend you would get in a premixed 10ml bottle from the same manufacturer. The only difference is that the nicotine has been removed and you add it back yourself via the shot. Flavour quality does not drop with the bottle size, only the packaging and the unit price do.
What the October 2026 Vaping Products Duty changes
From 1 October 2026, all UK e-liquid carries a £2.20 per 10ml duty plus VAT. The duty is volume-based, so a 100ml shortfill picks up £22 in duty and a 10ml bottle picks up £2.20. The duty on two nic shots adds £4.40 to the 100ml setup. So post-duty: 100ml + 2 shots = £12 base + £26.40 duty = £38.40 for 120ml = 32p per ml. The same 120ml in 10ml bottles = £42 base + £26.40 duty = £68.40 for 120ml = 57p per ml. JUSTVAPE 100ml is still cheaper per ml after the duty, the gap just narrows from 70% to 44%.
Heavy vapers (5ml+ per day)
Biggest absolute savings. £700+ a year for 10ml-per-day vapers, even more once duty applies on 1 October 2026.
Long-term flavour loyalists
If you know the exact flavour and strength you want, 100ml saves significantly. Less worthwhile if you change flavour every week.
Flavour sampling
If you want to try lots of different flavours, 10ml bottles are still the easier way to sample. Use 100ml for your daily driver.
Higher strength vapers
Maximum practical 100ml shortfill strength is 6mg. If you need 10mg or 20mg, 10ml nic salt bottles are your only option.
4 ways the 100ml format costs less than 10ml
The price gap is not just one thing. Four separate cost lines add up to make 10ml bottles fundamentally more expensive than 100ml shortfills.
Packaging cost
One 120ml bottle, one cap, one label vs twelve of each. Packaging is roughly 30% of the unit cost of a 10ml bottle, and that cost is shared across far more volume in a 100ml format.
Filling and labelling labour
Filling one 120ml bottle on a production line takes a fraction of the time and effort of filling twelve 10ml bottles. That labour cost difference flows through to retail price.
Storage and shipping efficiency
One 120ml bottle takes less shelf space, less packaging materials and less shipping weight than twelve 10ml bottles. Every step of the supply chain is cheaper at scale.
Retail margin spread
Retailers can offer larger absolute margin on a 100ml bottle but lower margin per ml. Customer gets a better deal, retailer still makes a fair profit on a bigger basket value.
