A year ago, anything over 600 puffs was either illegal or deeply suspect. The high puff count disposables doing the rounds in corner shops and market stalls were almost universally non-compliant. Trading Standards kept seizing them. News outlets kept running scare stories about unregulated liquid from Chinese factories with no MHRA oversight. If someone offered you a 5,000 puff vape in 2024, the smart money said it was dodgy.
Now you can walk into a legitimate UK retailer and buy a 20000 puff vape kit that’s fully TPD compliant. Rechargeable battery. Properly registered liquid. Legal in every respect. The shift happened fast, and most people outside the industry haven’t caught up with it yet.
The Regulatory Loophole That Isn’t Actually a Loophole
Call it clever engineering rather than a loophole. TPD rules say prefilled pods can’t exceed 2ml. Nicotine strength can’t exceed 20mg/ml. Neither of those limits has changed. What manufacturers figured out is that nothing in the regulations limits how many pods you can bundle with a single rechargeable kit.
So a 20,000 puff product doesn’t have some enormous tank hidden inside it. The kit ships with a stack of individual 2ml pods. Each one is compliant on its own. You vape through one, pop it out, slot the next one in. The battery recharges via USB-C between pods. Total puff count across every pod in the box hits 20,000. Completely legal. Every pod is individually registered.
There’s an elegance to it that the old illegal disposables never had. Those products just crammed oversized tanks into plastic shells and hoped nobody checked. These kits are actually engineered around the constraints. Better products came out of tighter rules. Funny how that works.
Who’s Buying Them and Why That Surprised Everyone
Former disposable users, obviously. The ones who used to burn through two or three BM600s a day. A 600 puff disposable lasted them about four hours. They were spending thirty quid a week easy, sometimes more if they kept one in the car and one in their jacket.
What caught retailers off guard was the second wave. Delivery drivers. Reps who spend all day in a van or on trains. People whose work means they can’t nip to a shop easily. For them the appeal isn’t about flavour or brand loyalty. It’s about not having to think about vaping supplies for three or four days at a stretch. Grab a full 20K kit on Monday, forget about it until Thursday. That’s worth paying extra for when your schedule doesn’t leave room for regular top-ups.
Then there’s the forum crowd who did the per-puff maths and won’t shut up about it. Fair play to them. The numbers do stack up. A 20,000 puff kit at £20 works out cheaper per puff than almost any small prefilled system. Once someone puts that calculation in front of you, it’s hard to argue with it. Vaping forums have entire threads dedicated to nothing but cost breakdowns across different puff count brackets. It’s the kind of content that only obsessives produce, but that ends up influencing thousands of buying decisions.
The Corner Shop Era Is Properly Over
This is the bit that interests me most. You cannot impulse buy a 20,000 puff kit. The price point is wrong for it. Fifteen to twenty-five quid. Nobody grabs that off a counter the way they used to grab a fiver disposable on the way out of a newsagent.
These are products people research before buying. Which brand? Which flavours? Is the pod system compatible with the spare pods available separately? Does the battery last long enough between charges? That’s ten minutes of browsing minimum, probably more for someone buying their first one. And ten minutes of product research happens on a phone or laptop, not standing at a counter with a queue behind you.
Physical vape shops stock some of these kits, but they can’t carry every flavour in every brand. The product range is too wide. Online retailers don’t have that problem. List everything, let people filter and compare, ship it the next day. The buying behaviour that high puff count products require is a perfect match for online shopping. No getting around it.
The Tax Nobody’s Thought Through Properly
October 2026 brings the £2.20 per 10ml excise duty on all vape liquids sold in the UK. It applies to prefilled pods and bottled liquid equally. But the impact isn’t equal at all.
A 10ml bottle of nic salt liquid that currently costs £3.99 will jump to roughly £6.19. That’s a 55% price increase on one of the cheapest vaping products available. For a 2ml prefilled pod, the proportional tax is smaller in absolute terms. The pod was already more expensive per ml than bottled liquid, so the tax adds a smaller percentage on top.
What this means in practice is that the gap between “cheap refillable” and “convenient prefilled” gets narrower after the tax lands. The whole reason some people chose refillable kits was the cost savings. When that saving shrinks, some of them will switch to prefilled high puff systems instead. Pay a bit more per puff but skip the hassle of filling pods and changing coils.
I haven’t seen anyone in the industry talk about this dynamic yet. Probably because most of the commentary around the tax focuses on whether it will push people back to cigarettes. That’s the dramatic headline. The quieter story is how it reshuffles purchasing patterns within vaping itself. High puff count prefilled kits come out of the tax looking relatively better than they went in.
This Category Has Barely Started
Manufacturers are already working on 25,000 and 30,000 puff systems. At some point, the puff count number becomes pure marketing and stops reflecting a meaningful product difference. We’re probably close to that point already. The actual competition over the next twelve months will be about pod flavour quality, how quickly batteries charge, and whether the pods seal properly without leaking in your pocket.
The 20,000 puff bracket went from nonexistent to one of the fastest-growing product categories in UK vaping inside a single year. The products are legal, the economics work, and the customer base keeps expanding past the obvious former disposable users. For something most people still haven’t heard of, that’s a lot of momentum building very quietly.
