Signature 50ml: a nicotine-free shortfill at £5.49

Signature 50ml is a shortfill e-liquid, which means it arrives at 0mg with no nicotine in it whatsoever, in a bottle sized for you to finish the job yourself if you want nicotine in the final mix. At £5.49 for 50ml it sits at the affordable end of the shortfill market, and understanding what that format is actually for explains why a bottle five times the size of a nic salt costs less than two of them.

The short version is that UK regulation caps any e-liquid containing nicotine at 10ml per bottle and 20mg per millilitre. Those rules apply to the nicotine, not to the flavoured base. A liquid with no nicotine in it is not subject to the bottle size limit, so manufacturers make the flavoured part in larger volumes, sell it as it stands, and leave the customer to add a separate nicotine shot at home if they want one. That is the whole idea behind the shortfill, and it is a direct product of how the law is written rather than a marketing invention.

Bought as it comes, this is a complete zero nicotine e-liquid. Plenty of adults buy shortfills exactly this way and never add anything, either because they never wanted nicotine or because they have stepped down over time and no longer do. The bottle is not incomplete. It simply has an option attached to it.

Signature is listed here as a single product rather than a sprawling range, which you can see on the Signature collection page. The wider shortfill e-liquid section is where to look if you want to compare it against the rest of the large format market before committing.

Nicotine shots and the arithmetic that goes with them

If you do want nicotine in this bottle, the process is a piece of primary school arithmetic and it is worth doing once so you understand what you are making rather than following instructions blindly.

A nicotine shot is a 10ml bottle of unflavoured liquid containing nicotine at the legal maximum or close to it. Shots are sold separately, and they are the only part of the equation the bottle size rules apply to.

One shot into a 50ml shortfill. A 10ml shot at 18mg contains 180mg of nicotine in total. Add it to 50ml of 0mg liquid and you have 60ml of finished liquid holding 180mg, which works out at 3mg per millilitre. Using a 20mg shot instead gives you 200mg across the same 60ml, or a shade over 3.3mg per millilitre. Both land in the low strength band that suits open tank vaping.

Why 3mg is the usual target. Shortfills are designed for devices that produce a lot of vapour per draw. At that volume, low strength is not a compromise, it is a requirement. Putting 20mg liquid through a high output setup would be genuinely unpleasant, which is why the entire shortfill category is built around ending up at roughly 3mg rather than anywhere near the legal ceiling.

A 50ml shortfill is conventionally supplied in a bottle with headroom left above the liquid for exactly one shot, so the volumes are designed to work out. If you want a stronger final mix than one shot provides, you would need to decant some of the base first to make room, and at that point you are moving away from what the format is designed for. Our nicotine salt range is the more sensible answer for anyone who wants higher strength, since those bottles arrive ready to use.

Mixing it properly, and why patience helps

Adding a shot takes a couple of minutes. Doing it carelessly is how people end up with a bottle that tastes thin for a week and then mysteriously improves.

1. Stand the shortfill upright and remove the cap. Some bottles have a child-resistant closure that needs pressing down while turning.
2. Pour the full shot in steadily rather than squeezing it. There is no advantage to speed and a squeezed bottle spits.
3. Replace the cap and check it is tight before you do anything else.
4. Shake it properly. Not a polite swirl, a genuine shake for a minute or so. You are dispersing a thin liquid through a thicker one and it needs the agitation.
5. Leave it to stand for a few hours, then shake again. This second pass catches anything that has settled and is the step that separates a well mixed bottle from a streaky one.

Steeping is the other half of the story. A freshly mixed bottle often tastes slightly flat or disjointed, because the flavour compounds have not had time to settle into the base. Leaving it somewhere cool and dark for a few days lets that happen. Fruit and menthol blends tend to need very little. Dessert, custard and tobacco profiles usually reward a longer wait, sometimes a week or more, and the difference is not subtle when you come back to them.

The practical habit is to mix your next bottle when you open your current one. That way there is always something steeping and you never have to vape a bottle on the day you mixed it. It costs nothing and it removes the only real drawback of the shortfill format.

What kind of device this suits

Shortfills and small pod systems are usually a poor match, and knowing why saves a wasted purchase.

Liquids made in this format are generally blended for open tanks and higher output devices, which means a thicker base with a high proportion of vegetable glycerine. That thickness is what produces dense vapour, and it needs wide wicking channels and a decent amount of airflow to move through properly. Feed it into a compact pod designed for a tight cigarette-style draw and the wick struggles to keep up, which shows itself as a dry, scorched taste that gets wrongly blamed on the pod.

The right home for a shortfill is a device you draw on directly into the lungs, with adjustable airflow and a coil built for volume. If that is not what you own, the honest answer is that this is the wrong liquid for your hardware, and a 10ml nic salt bottle will serve you far better. There is no snobbery in either direction here, they are simply different tools.

If you are considering moving to an open tank setup, our vape kits section covers the devices that handle this style, and the vape coils section holds the replacement heating elements those devices consume. Coils are the running cost on an open system in the same way pods are on a closed one, and sweeter liquids shorten their life noticeably, which is worth factoring in before you commit to a dessert-heavy rotation.

One more practical point. Larger devices get through liquid much faster than pod systems do, which is precisely why the liquid comes in 50ml bottles rather than 10ml ones. A shortfill that looks enormous next to a nic salt bottle may well last you a similar length of time.

Cost per millilitre, and how the formats compare

Comparing e-liquid prices across formats is where most people go wrong, because they compare bottle prices rather than volumes.

At £5.49 for 50ml, this works out at just under 11p per millilitre as supplied. Add a nicotine shot and you have 60ml of finished liquid, so the cost per millilitre depends on what the shot cost you, but the base itself has already brought your average down substantially compared with buying small bottles.

Set that against the 10ml format. A 10ml nic salt bottle at, say, £3 is 30p per millilitre. Even at multibuy pricing, where 10ml bottles come down considerably, the shortfill format tends to win on pure volume economics. That is the trade the format offers: you accept a mixing step and a wait, and in return you pay materially less for the liquid.

Where the 10ml bottles win is convenience and strength. They arrive finished, they suit pod systems, and they are available at strengths a shortfill cannot practically reach. Neither format is objectively better value, they are optimised for different things. The full e-liquid range holds both, and it is worth being clear about which you are shopping for before you compare prices.

Two habits genuinely reduce what you spend. The first is buying in the sizes that match your consumption instead of topping up constantly at whatever price is in front of you. The second is watching the offers rather than paying full price by default, and our vape deals section collects the current multibuy pricing across both formats. Neither of those requires changing what you vape, which is why they are the first place to look.

Storing a large bottle so it lasts

A 50ml bottle takes longer to get through than a 10ml one, which makes storage a real consideration rather than an afterthought.

Keep it dark. Light degrades flavour compounds and gradually darkens the liquid. A cupboard or a drawer is ideal. A shelf by a window is the worst place in the house for it.

Keep it cool and stable. Heat accelerates oxidation, which is what turns a bright fruit blend muddy and pushes a tobacco profile towards something stewed. Room temperature in a cupboard is fine. Above a radiator is not.

Keep it sealed. Air is the other agent of change. Cap it firmly after every use rather than leaving it open on a worktop while you get on with something else.

Expect some darkening anyway. Liquid that has gone slightly amber has usually just oxidised a little and is generally still perfectly good. Judge it by taste rather than colour.

Keep it away from children and animals. This matters more once nicotine has been added, and it matters regardless of that. Child-resistant caps are a safeguard, not a substitute for putting the bottle somewhere out of reach.

One final note on the zero nicotine version specifically. Because nothing has been added, an unopened shortfill keeps well for a long time, and buying ahead is a reasonable thing to do when the price is right. Once a shot goes in, treat it more like a perishable and aim to get through it over weeks rather than leaving it indefinitely. The nicotine-free e-liquid range covers the rest of what we stock in this category if you are stocking up.

How this is sold and shipped

Genuine product

What we list is authentic stock through proper UK channels. E-liquid is a product you inhale, and the manufacturing standards behind a compliant, notified product are the reason it can be sold here at all. Liquid from unaccountable sources has not necessarily been through any of that, and there is no way to assess a bottle by looking at it. Buying from a UK retailer that answers for its supply chain is the straightforward safeguard.

Getting it to you

Order before the 4pm weekday cut-off and it leaves us that day. Anything later, or over a weekend, goes out with the next working day's collection. Baskets over £20 ship free within the UK. A single 50ml bottle at £5.49 does not reach that, but three or four do comfortably, and buying a couple of months of liquid at once is the way most regular vapers order.

Age verification

Everything on this site is sold to adults aged 18+ only, and that includes zero nicotine liquid. UK law treats vaping products as an age-restricted category as a whole rather than drawing a line at nicotine content. Checks run automatically at checkout, and where an automated verification cannot be completed we will ask you for identification before your order is packed and sent.

Where this sits in the Signature range

A single product tells you little; the shape of the range tells you a lot. We stock 1 Signature products, running from £5.49 to £5.49. That makes it a small, specialist range rather than a catalogue brand.

The full lineup is on the Signature page.

Staying within a brand you already rate is the low risk way to try something new.

How it compares to the rest of the category

The useful question is not what it costs, but what else that money buys. We list 736 products in this category. At £5.49, this one sits in the middle of the market.

• Multibuy deals are where the price per unit drops hardest, and they can be mixed across flavours.
• Reduced lines carry 1,558 products if the budget is the deciding factor.
• Prefilled pods cost more per millilitre but remove the refilling entirely.

The honest answer is that most vapers end up owning two formats, not one.

The running cost, worked out

Work out cost per week and product comparisons get much easier.

Without a published rating there is no honest per-puff maths to show, so we leave it out.

• No multibuy runs on this line, so the deals page is where the savings are.
• Baskets over £20.00 ship free in the UK, so building to that threshold beats paying postage twice.
• Nicotine strength changes consumption: many adults find a higher strength means reaching for the device less often.

Why the UK market looks like this

It helps to know which limits are legal and which are commercial. UK rules cap nicotine at 20mg per ml, nicotine e-liquid bottles at 10ml, and prefilled pods and tanks at 2ml. That is why you buy small bottles often rather than one large one.

Since single-use devices were banned, the market moved to rechargeables. Rechargeable kits with replaceable pods took their place, which is why a device now comes with a charging port and a pod you swap rather than a sealed unit you bin. It also means the device outlives the flavour, which changes how you shop.

All stock here meets those UK limits and comes through UK distribution. Sales are 18+ and every order is age-checked.

Buying this as a first purchase

If this is your first order with us, a few things are worth knowing before you commit.

1. Format. A bottle is the cheapest way to vape per millilitre, but you refill it yourself. Prefilled pods remove that job at a higher cost.
2. Strength. This comes in 0mg. Heavier former smokers usually start high and step down.
3. Flavour. Pick two from different families rather than committing to one.

Everything else is preference rather than a decision that costs you money. The deals page is the cheapest way to try more than one at a time.

Looking after it, and what goes wrong

The faults people blame on a product are usually storage or priming.

• Prime before the first draw. Fill, then wait a few minutes so the wick soaks fully. A dry first pull is what burns a coil.
• Keep it cool and upright. Heat thins liquid and pushes it through seals, which is why a hot car is the usual cause of a leak.
• Muted flavour is often you, not it. Palate fatigue is common on a single flavour, and rotating to a second profile resets it.
• Store away from children and pets, and recycle spent hardware rather than binning it loose.

Do those four things and most of the usual problems never appear.

Delivery, returns and buying with confidence

Here is what happens after you order. Weekday orders placed before 4pm are dispatched the same day, and UK delivery is free once your basket reaches £20.00. You pick the service at checkout.

Consumables cannot be returned once opened, for obvious hygiene reasons. If something arrives faulty or incorrect, contact us and we will sort it. Age verification applies to every order, and unverified orders are refunded rather than sent.

Nicotine is an addictive substance and these products are intended for adults who already smoke or vape.

Nicotine strength, explained properly

Of every decision on this page, strength is the one worth thinking hardest about. This listing offers 0mg. UK law caps nicotine at 20mg per ml, so nothing sold legally here goes higher, and the honest question is how far below that ceiling you should sit.

The instinct is to go low, and it usually backfires. If a strength does not satisfy, you compensate by vaping more often, which costs more and rarely feels better. A heavier former smoker typically starts at the top of the range and steps down over weeks or months once the habit has settled. Someone who smoked lightly, or who has already been vaping a while, is usually comfortable in the middle.

Throat feel matters too. Higher strengths give a firmer hit at the back of the throat, which many people switching from cigarettes actively want, and which others find harsh. Nicotine salts are smoother than freebase at the same number, which is why bar-style liquids sit at 20mg without feeling like it. If you are unsure, buy one of each rather than committing to five of the wrong one. 10mg options and 20mg options are browsable separately.

Where Signature fits in the wider market

Not all vape brands do the same job, even when they sit on the same shelf. We list 1 Signature products, a compact range built around a few core lines. The complete list is on the Signature page.

Breadth cuts both ways. What it does give you is somewhere to go when you want a change without gambling on an unfamiliar name. Brands that make both hardware and liquid tend to design them to work together, which is why pods from one family rarely fit another. Brands that only make liquid put their effort into flavour development instead, and often outperform the hardware houses on taste alone.

What this means in practice: Once you find a brand whose profiles suit your palate, its other lines are a far safer bet than a random product at the same price. That is worth more than it sounds in a category where you cannot try before you buy. The full category runs to 736 products if you would rather compare across brands than within one.
