The Cheapest Way to Vape After the October 2026 Tax

Once the Vaping Products Duty starts on 1 October 2026, every millilitre of liquid you use carries about 26.4p of duty and VAT. That single fact reshapes what "cheap vaping" means.

It's no longer about hunting the lowest bottle price. It's about millilitres per week. Cut those and everything else follows.

1. Match the device to the nicotine, not the clouds

This is the biggest lever by a distance, and it's worth understanding why.

A high-wattage sub-ohm setup runs low-strength liquid — typically 3mg — so it has to vaporise a lot of millilitres to deliver the nicotine you want. An MTL pod kit runs nic salts at 10mg or 20mg, so far fewer millilitres carry the same nicotine.

In practice:

• Sub-ohm DTL — often 60–100ml a week. Duty cost: roughly £16–£26 a week.

• MTL pod kit on nic salts — often 10–15ml a week. Duty cost: roughly £2.60–£4 a week.

That's the same nicotine, the same satisfaction, and a difference of over £1,000 a year in duty alone. If you like big clouds, that's a legitimate choice — just now a considerably more expensive one. Our MTL vs DTL guide explains how the two styles actually feel.

2. Get your nicotine strength right

Under-strength liquid is quietly expensive. If the strength is too low, you compensate by vaping more — more millilitres, more duty, and usually less satisfaction. People switching from smoking often start too low and end up chain-vaping.

Getting this right is worth real money now. See what nicotine strength a beginner should use and 10mg vs 20mg nic salt.

3. Refillable over prefilled

The duty on 8ml is the same however you buy it — but the liquid underneath isn't. Prefilled pods run around £1.50 per ml; bottled nic salt is nearer 40p per ml. Over a year that gap dwarfs the duty. The full comparison is in the vape tax and prefilled pods.

4. Look after your coils

A burnt or clogged coil makes liquid taste bad, and the usual response is to vape more of it chasing the flavour — or to dump a half-full tank. Both cost you duty now.

• Prime new coils properly — see how to prime a vape coil.

• Replace them before they taste burnt, not after — how often to replace a vape coil.

• Fix leaks promptly. Liquid on the desk is liquid you've paid duty on — how to stop your vape leaking.

5. Pick flavours you'll finish

Duty makes impulse-buying flavours you don't get on with more expensive. Sticking to a reliable all-day vape and buying it in sensible quantities beats a drawer of half-used bottles.

The kit that costs least to run

If you want the lowest running cost from October, the answer is consistent: a refillable MTL pod kit, run on 10mg or 20mg nic salts, with coils changed on time. It's the lowest millilitres-per-week format available, and the devices themselves are inexpensive.
