Enter your shortfill and target strength — results update as you type.
Heads up — nic shots are still free with shortfills, for now. The UK vaping products duty (£0.22/ml, live since 1 October 2026) applies to nicotine shots too, adding around £2.64 of tax to each 10ml shot once VAT is included. We're still giving them away free with shortfills, but they'll have to become chargeable before long. See our vape tax guide or work out the impact with the vape tax calculator.
