Replacement coils are the consumable inside any reusable vape — a small heating element wrapped in cotton wicking that vapourises e-liquid. They're the single biggest factor in how your vape tastes, lasts, and performs. Replace them on schedule and your device performs as designed; push past their lifespan and flavour goes muted, then burnt. We stock genuine UK-compliant replacement coils across all major pod kits, sub-ohm tanks, and mod systems.
Coil Resistance Explained (Ohms)
Resistance is measured in ohms (Ω). Higher resistance (1.0Ω+) = less current flow = less heat = MTL pod-kit style. Lower resistance (sub-ohm, under 1.0Ω) = more current flow = more heat = sub-ohm DTL cloud style. 1.2Ω coils suit tight MTL cigarette-style draws with 20mg nic salts. 0.8Ω coils give looser MTL or restricted DTL with 10mg salts. 0.6Ω–0.8Ω coils support RDTL pod kits like Smok Nord 5 with 5–10mg salts. 0.15Ω–0.4Ω sub-ohm coils need 3mg shortfills and proper mods. Match the coil to your device and e-liquid.
Mesh vs Standard Coils
In 2026, almost all UK replacement coils are mesh — a flat sheet of perforated resistance metal rather than the older spiral wire-wound design. Mesh offers larger heated surface area, more even heating, faster ramp-up, fuller flavour, and longer life than wire-wound coils. Dual mesh (two paired mesh elements) appears in premium devices for even better flavour persistence. Wire-wound coils still exist in some niche products but mesh is the modern standard. Pay attention to coil brand reputation rather than mesh marketing alone — a quality mesh coil from a reputable brand outperforms a cheap mesh coil from a budget brand.
When to Replace Your Coil
Coils don't usually fail dramatically — they fade. Watch for these signs in order: slightly muted flavour (first warning), reduced vapour production, dark or off taste, gurgling sounds, persistent burnt taste. Replace at sign 1 or 2. Don't push through to burnt — once cotton scorches, it's permanent and you've ruined the coil. Realistic lifespan with proper care: pod-kit coils 1–2 weeks, replaceable pod coils 2–3 weeks, sub-ohm coils 1–2 weeks of daily use. Sweet, dark, or dessert e-liquids shorten this dramatically — sometimes by half.
Priming a New Coil (Critical)
Firing a dry coil scorches the cotton on the first puff — once scorched, it stays scorched. To prime: drip 2–3 drops of e-liquid directly onto each visible wicking hole, fit the coil or pod into your device, fill the tank, then wait 5 minutes for the wick to saturate fully (10 minutes for sub-ohm). Take 3–4 gentle dry pulls before firing, then take your first proper puff slowly. This single habit prevents most burnt-taste complaints and dramatically extends coil life.
Compatibility — Match Your Device
Coils aren't universal. Caliburn G3 uses sealed-coil pods (you replace the whole pod). Oxva Xlim Pro takes replaceable coils inside reusable pods. Smok Nord 5 uses RPM 3 coils. Vaporesso XROS uses GTX coils. Sub-ohm tanks use brand-specific coils — TFV, GTX, Cleito, Z Max all different. Check your device's compatible coil family before buying. If you're not sure, our product listings include compatibility info, and our chat support can confirm before you buy.
Replacement Coils FAQ
Can I clean and reuse a worn coil? For pod-kit coils, no — cotton stays soggy after rinsing. For sub-ohm coils, technically possible (dry-burn for stainless steel, rinse for some types) but rarely worth it — new coils are £3–£5 and cleaned ones never fully recover flavour. For rebuildable atomisers, yes — that's the whole point.
Why are my coils dying so fast? Common causes: skipped priming, wrong e-liquid (high-VG shortfill in pod kit), running tank dry, chain-vaping, sweet flavours, over-wattage. Address whichever applies. Coil life of 3 days under careful use is rare — usually it's one of these factors.
How much should coils cost? UK genuine coils typically run £2.50–£5 each, often £8–£15 for 3–5 packs. Multi-buy is usually cheaper per unit. Anything dramatically below this from unknown sellers is likely counterfeit.
Can I use a higher-wattage coil than recommended? Best to stay within the printed wattage range on the coil. Over-wattage scorches cotton, mutes flavour, and dramatically shortens life. Start at the lower end of the range and adjust upward.
