Longfill vs Shortfill Which Gives Better Value for Money
Longfill vs shortfill:
which gives better
value for money?
Longfills edge ahead on cost per millilitre but shortfills win on speed. Here is the honest UK head-to-head covering price, strength flexibility, convenience plus the 2026 vape tax impact on both.
Longfills give slightly better value per millilitre. A 60ml finished longfill lands at roughly 17p per ml compared with 22p per ml for a 50ml shortfill plus one 10ml nic shot. The gap is about 20 to 30 percent in favour of longfills. Longfills also offer more strength flexibility (0mg to 9mg) whereas shortfills are locked at 3mg once the nic shot is added. Shortfills win on speed since you only add one shot instead of three. Value-focused vapers pick longfills. Convenience-focused vapers pick shortfills.
Three numbers
that decide value
Price per ml in the longfill camp, price per ml in the shortfill camp, plus the annual saving from switching.
Longfill per ml
Roughly £10 for 60ml finished at 3mg strength using a matched Mixer Kit.
Shortfill per ml
Roughly £13 for 60ml finished at 3mg strength from a 50ml shortfill plus one shot.
Annual saving
Typical saving for moderate vapers (5ml daily) switching from shortfills to longfills over a full year.
Longfills are cheaper per ml. Shortfills are faster to prepare. That is the real difference.
Both formats solve the same fundamental UK problem: getting more than 10ml of finished nicotine e-liquid in a single transaction despite the TPD cap on individual bottles. Shortfills do this by selling you 50ml of pre-mixed nicotine-free liquid in a 60ml bottle then adding one 10ml nic shot to finish at 3mg. Longfills do it by selling you 30ml of flavour concentrate in a 60ml bottle then adding three 10ml nic shots from a Mixer Kit. Both formats produce roughly 60ml of finished vapeable liquid.
The value difference comes from what ships in each bottle. A shortfill bottle ships with 50ml of pre-mixed base liquid which costs the manufacturer more to produce, bottle plus transport. A longfill ships with only 30ml of concentrate. The base liquid portion (PG, VG and nicotine) is supplied by you through the separately bought Mixer Kit. The manufacturer saves around 20 to 30 percent on production plus shipping. That saving is passed to you in the final price per millilitre of finished e-liquid.
Strength flexibility is the second meaningful difference. A shortfill plus 10ml shot always finishes at 3mg in a 60ml bottle. The nicotine maths is fixed. A longfill paired with a Mixer Kit can finish at 0mg, 3mg, 6mg, 9mg, 5mg nic salt or 10mg nic salt depending which kit you buy. This matters for vapers stepping down their nicotine level. It also matters for anyone outside the 3mg shortfill default.
What about convenience and speed?
Shortfills win here. Adding one 10ml shot, shaking the bottle plus vaping takes about 60 seconds. Adding three 10ml shots plus shaking takes closer to 3 minutes. Neither is slow in absolute terms but the shortfill path is noticeably faster for impatient vapers. Shortfills also produce slightly less packaging waste per bottle since you receive one shot instead of three.
Flavour plus ratio options tilt back toward longfills. The UK market has more longfill flavours available than shortfill flavours in 2026 because longfills are easier and cheaper for brands to launch. A new flavour can be bottled as concentrate plus paired with any existing Mixer Kit. A new shortfill flavour requires the manufacturer to pre-mix the full 50ml at a specific ratio. Most new UK e-liquid launches in recent years have followed the longfill format for this reason.
- Cost per ml. Longfill wins. Roughly 20 to 30 percent cheaper.
- Strength flexibility. Longfill wins. 0mg to 9mg choices vs 3mg fixed.
- Speed of preparation. Shortfill wins. One shot vs three.
- Flavour range in UK. Longfill wins. More brands plus variants.
- Packaging waste. Shortfill wins slightly. Fewer small bottles.

Longfill wins 6-2 on value plus flexibility
Shortfills win only on convenience plus speed. For vapers who care about cost per millilitre, strength choice plus flavour range, longfills are the clear pick. For ex-smokers at 3mg who want to open a bottle plus vape in under a minute, shortfills remain a valid choice.
