Summary: Picking an e-liquid isn't about grabbing the flavour with the loudest label. It's about matching nicotine strength, PG/VG ratio and bottle format to the device sitting in your pocket. This guide walks through the five decisions that actually matter, then breaks down the product categories you'll run into while shopping. It also flags the mistakes that quietly waste money — or send new vapers straight back to cigarettes. Browse the current range before you commit to anything.
Why This Purchase Is Trickier Than It Looks
Walk into the vaping aisle of a corner shop, or open a retailer's site like Totally Wicked's, and the sheer number of SKUs is the first problem. Ten nicotine strengths. Three or four PG/VG ratios. Bottle sizes from 10ml to 120ml. Devices that only accept certain coil types, and e-liquids that only behave properly in certain devices. None of it is labelled for beginners.
Most of the confusion collapses into two questions: what's actually going into your body, and what's your device built to handle? Get those two right and everything else — flavour, price, brand — is just preference.
This matters more in 2026 than it did five years ago. The market has split cleanly into two lanes: nicotine salt e-liquids paired with small pod systems, and freebase shortfills paired with sub-ohm tanks. Buy the wrong liquid for your device and you'll either get no nicotine hit at all or a coil that's dead within days. Both are common, avoidable, and expensive mistakes.
Who This Guide Is For — and Who Should Skip It
You'd benefit from reading on if you're new to vaping, switching from smoking, replacing an old device, or just tired of guessing which bottle fits your kit. Anyone buying their third or fourth device already knows most of this.
If you're a long-time vaper with a settled setup and a favourite flavour house, there's less here for you — go reorder what already works. And if you don't currently use nicotine in any form, this isn't a guide encouraging you to start. Vaping products are formulated and sold as a nicotine-delivery alternative for existing adult smokers and vapers, not as a general consumer product.
The Five Things to Get Right Before You Buy
1. Nicotine strength
UK e-liquids are typically sold in 0mg, 3mg, 6mg, 10mg, 12mg, 18mg and 20mg strengths, depending on format. Heavy smokers (20+ cigarettes a day) usually start around 18–20mg in a nic salt format. Light or social smokers often do fine at 6–12mg. Go too low and you'll compensate by vaping constantly, chasing a hit that isn't there. Go too high in the wrong device and the throat hit turns harsh enough that people give up within a week.
2. Freebase vs. nicotine salt
This is the split that decides everything else downstream. Freebase nicotine is the traditional form, smoother at low strengths, and it's what you'll find in shortfill bottles designed for sub-ohm tanks. Nicotine salt is a more efficient, faster-absorbing form that works at higher strengths without the harsh throat hit — it's built for small pod kits with high-resistance coils. Put nic salt in a sub-ohm tank and it'll taste burnt and overwhelming. Put freebase 3mg liquid in a pod kit and you'll get almost no hit at all.
3. PG/VG ratio
PG (propylene glycol) carries flavour and throat hit; VG (vegetable glycerine) carries vapour volume and smoothness. High-PG liquids (50/50 or 60/40) suit pod systems and mouth-to-lung devices. High-VG liquids (70/30 and above) suit sub-ohm tanks built for big clouds. Some people are mildly sensitive to PG — dry mouth, sore throat — and switching to a higher-VG mix solves it more often than switching brands does.
4. Device compatibility
Coil resistance is the number that actually matters, not the device's marketing name. Coils above 1.0 ohm want nic salts and lower-VG liquids. Coils below 1.0 ohm — sub-ohm — want high-VG shortfills. Mismatch either direction and you'll burn through coils in days or get a weak, flavourless draw.
5. Bottle size and format
Shortfills (usually 50ml or 60ml, sold at 0mg) are designed to have one or two 10ml nicotine shots added, landing around 3mg once mixed — cheaper per ml than pre-mixed bottles if you vape in volume. Nic salt e-liquids come pre-mixed in 10ml bottles, ready to use, no shots required. If you're going through more than a bottle or two a week, shortfills work out considerably cheaper over a month.
What You'll Actually Find on the Shelf
Here's roughly what the core product categories cost in the UK market. Treat the prices as typical ranges, not a live price list — check the current listing for exact figures before buying.
| Product type | Typical price range (GBP) | What it's built for | Who it fits |
|---|---|---|---|
| 10ml nic salt e-liquid | £3.50 – £5.00 | Pod kits, coils 1.0ohm+ | Smokers switching over; anyone wanting a strong, quick hit |
| 50–60ml shortfill (0mg) | £8.00 – £15.00 | Sub-ohm tanks, add nic shots separately | Regular vapers who want lower cost per ml |
| 10ml nic shot (18mg) | £1.00 – £2.00 | Mixed into shortfills to reach ~3mg | Anyone buying shortfills |
| Pod starter kit | £10.00 – £25.00 | Small, portable, high-resistance coils | Beginners and smokers quitting cigarettes |
| Sub-ohm tank kit | £20.00 – £40.00 | High-VG liquid, bigger vapour | Experienced vapers, flavour-and-cloud chasers |
| Replacement coils (pack of 5) | £8.00 – £15.00 | Wears out every 1–3 weeks with regular use | Everyone — budget for this as a recurring cost |

Three Mistakes That Waste Money
Buying the strongest nicotine strength "to be safe." It backfires. Too-strong nic salt liquid in a pod kit causes harsh throat hits that make people vape less, not more — which defeats the point if you're trying to replace cigarette nicotine consistently.
Ignoring coil resistance entirely. The device's box rarely shouts this number at you, but it's on the coil packaging. Five minutes checking it before you buy liquid saves a burnt-out coil and a wasted bottle.
Forgetting coils are a recurring cost. A pod kit or tank looks cheap upfront. The coils you'll replace every couple of weeks are where the real ongoing spend sits — budget for it the same way you'd budget for razor blades or printer ink.
FAQ
Q: What nicotine strength should a former 20-a-day smoker start with?A: Most people in that range start around 18–20mg in a nic salt format, then adjust down after a week or two once they know how often they're actually vaping.
Q: Can I put a shortfill liquid straight into a pod kit?A: Not really. Shortfills are typically 0mg freebase liquid meant for sub-ohm tanks. Add nic shots and it's still a freebase mix, which will underperform in a high-resistance pod coil built for nic salts.
Q: How long should a coil actually last?A: Usually one to three weeks with daily use, less if you're running high-VG liquid through a low-resistance coil or vaping heavily. If flavour turns burnt or muted, that's the coil, not the e-liquid.
Q: Is it legal to order vape products online in the UK?A: Yes, for adults of legal age, though reputable retailers verify age at checkout and won't ship to under-18s. Rules and permitted nicotine strengths are set under UK vaping regulations and can vary slightly for other markets.
Q: I'm switching from cigarettes — do I need a strong device or a strong liquid?A: Liquid strength matters more than device power at the start. A simple pod kit with the right nic salt strength replicates a cigarette's hit far better than a powerful sub-ohm setup with the wrong liquid.
Q: Does higher VG always mean better flavour?A: Not automatically — it means bigger vapour and a smoother draw at higher wattages. Flavour intensity is more about the liquid's flavouring concentration and your device's power than the PG/VG split alone.
