Both prefilled pod systems and refillable pod kits are fully legal in the UK after the 1 June 2025 disposable ban, because both meet the legal requirements of being rechargeable and refillable (in the case of prefilled, through replaceable pods rather than bottle top-up). The choice between them comes down to five practical differences: cost, convenience, flavour choice, environmental impact and consistency of experience.

On cost, refillable kits typically win significantly over time. A 10ml bottle of nic salt e-liquid at standard UK pricing delivers roughly the same puffs as a replacement prefilled pod, but at around half the cost per ml. For heavy users, that difference adds up to 50-80% lower annual spend on a refillable kit versus prefilled pods. The upfront device cost of a refillable kit is typically higher (often £25-50 versus £10-20 for prefilled starter kits) but you recover that within 2-3 weeks of normal use.

On convenience, prefilled pod systems win clearly. A pod swap takes 5 seconds with no e-liquid handling and no mess. A bottle fill on a refillable kit takes 30-60 seconds and involves a top-fill port, a dropper or screw cap and slightly more attention. For most people the convenience difference is minor; for some it matters a lot. On flavour, refillable kits win because you can use any e-liquid from hundreds of brands. Prefilled is limited to whatever flavours the brand offers in their pod range.

Cost comparison: real numbers across a year

For a moderate vaper using around 2ml of e-liquid per day (roughly equivalent to a 10-15 cigarettes per day smoker), the annual cost difference between prefilled and refillable is significant. A prefilled pod kit at around £4.50 per replacement pod (2ml) works out to around £820 per year of pods. A refillable kit at £2-3 per 10ml bottle of nic salt works out to around £130-220 per year of e-liquid plus around £30-50 of replacement coils. Total: around £180-270 per year versus £820 for prefilled. That is a saving of £500-650 annually for typical use.

Convenience comparison: what daily life looks like

Prefilled pod system daily routine: vape until the pod runs out (typically 1-3 days for a 600 puff kit, 10-40 days for a 6000 puff kit), swap the pod (5 seconds), continue. No bottles, no spills. Refillable pod kit daily routine: vape until the pod is empty (typically 1-2 days for a 2ml pod), open a 10ml bottle of nic salt e-liquid, unscrew or open the pod fill port, drip in roughly 2ml of liquid (30 seconds), close the port, vape. Replace the coil every 1-3 weeks depending on the kit. The refillable routine is slightly more involved but well within most people’s comfort range.

Flavour and customisation comparison

Prefilled pod systems are limited to the flavour range the manufacturer produces for that specific kit. Most major brands (Elf Bar, Lost Mary, Crystal, IVG, Hayati) offer 30-50 flavours per kit at 20mg/ml. Refillable kits can use any nic salt e-liquid from hundreds of brands, with thousands of total flavours across the market and nicotine strengths from 0mg to 20mg/ml. For users who want to experiment with flavours, mix flavours or step down nicotine gradually, refillable kits offer dramatically more freedom. For users who just want one or two reliable flavours, prefilled is fine.

In our Omagh and Strabane stores, the choice between prefilled and refillable usually comes down to four user types. Here is the framework we use to help customers decide.

For a hybrid setup using both formats, the compliant prefilled pod vape kits at Just Vape stocks prefilled pod kits alongside refillable starter kits and a full range of nic salt e-liquid bottles. Many of our regular customers use both: prefilled for the working week, refillable at home.
