Choosing to switch from smoking to vaping is a significant first step, but the world of vape juice can feel overwhelming. With so many options, how do you find the one that will make your transition successful? At Vape Offers, we've consulted our in-house stop-smoking specialists. We've also spoken to our vaping technicians to create the definitive UK guide.
Making the right e-liquid choice is crucial. It determines the satisfaction you get from each puff. It also influences how well your device performs, and ultimately, your success in leaving cigarettes behind for good. This guide will walk you through everything you need to know, from nicotine strength to flavour, all within the context of UK regulations.
Understanding Vape Juice Basics
Before you can choose the right e-liquid, it helps to know what’s inside the bottle. Getting to grips with the core components will empower you to make an informed decision that suits your needs perfectly.
What is Vape Juice?
Vape juice, also known as e-liquid, is the fluid used in vaping devices that creates the vapour you inhale. It’s a simple mixture, but each ingredient plays a vital role. In the UK, all e-liquids must be UK TRPR (TPD-derived) compliant, ensuring they meet strict safety and quality standards.
In the UK, nicotine-containing e-liquids must comply with regulations. These regulations are known as the Tobacco and Related Products Regulations (TRPR). Bottles with nicotine are limited to 10 ml, nicotine strength cannot exceed 20 mg/ml (2%), and tanks or cartridges are capped at 2 ml capacity. Labels and packaging must meet strict safety standards.
Under UK TRPR regulations, nicotine-containing e-liquid bottles are limited to 10 ml with a maximum strength of 20 mg/ml. Vape tanks or cartridges are restricted to a maximum capacity of 2 ml. The main components are:
- Propylene Glycol (PG): A thin, colourless liquid that is an excellent carrier for flavour. It provides the "throat hit" many ex-smokers look for.
- Vegetable Glycerin (VG): A thicker, slightly sweet liquid. Responsible for producing dense vapour clouds.
- Flavourings: Food-grade additives that create the vast range of tastes available.
- Nicotine: The addictive substance is also found in cigarettes. It is available in different forms and strengths.
In the UK, nicotine e-liquids must follow the Tobacco and Related Products Regulations (TRPR). Bottles with nicotine are limited to 10 ml, nicotine strength cannot exceed 20 mg/ml (2%), and tanks or cartridges are capped at 2 ml capacity. Labels and packaging must meet strict safety standards.
VG vs PG: What’s the Difference?
The ratio of VG to PG in your e-liquid is one of the most important factors affecting your vaping experience. Our technicians see this as the foundation of a good vape setup. A 50/50 vape juice offers a balanced experience, providing a noticeable throat hit and good flavour, making it a popular choice for beginners.
High-VG e-liquid (like a 70/30 VG/PG ratio) is thicker and produces larger, denser clouds with a smoother feel on the throat. In contrast, a higher PG ratio delivers a sharper throat hit, similar to a traditional cigarette. It also carries flavour more intensely. Understanding this PG VG ratio is key to matching a juice to your device and personal preference.
Choosing the Right Nicotine Strength
Evidence from the NHS supports vaping as less harmful than smoking (but not risk-free). The aim is to control cravings effectively so you can stop cigarettes completely.
Getting the nicotine level right is critical to managing your cravings and making the switch from cigarettes. Under UK TRPR regulations, vape tanks or cartridges are also restricted to a maximum capacity of 2 ml. This helps protect consumers and ensures compliance. Our specialists always advise starting with a strength that matches your previous smoking habits.
E-Liquid Strength Guide
In the UK, nicotine-containing e-liquid bottles are limited to 10ml, with a maximum strength of 20mg/ml (or 2%). Here’s a simple e-liquid strength guide to help you start:
A Quick Rule-of-Thumb: Cigarettes per day vs Starting Nicotine Strength
This table is for general guidance only and should not be taken as medical advice. Always listen to your body and consult a healthcare professional if unsure.
| Daily Cigarettes Smoked | Suggested Starting Nicotine Strength | Recommended Nicotine Type |
|---|---|---|
| 20+ | 18–20 mg/ml | Nicotine salts (smooth, strong cravings) |
| 10–15 | 10–12 mg/ml | Nicotine salts or freebase |
| Fewer than 10 | 3–6 mg/ml | Freebase (lighter, more flavour clarity) |
| 0 (just want to vape) | 0 mg/ml (nicotine-free) | Any |
For more on the safety of vaping and why many UK health bodies see it as less harmful than smoking, see the NHS guidance.
- Heavy Smokers (20+ cigarettes a day): Start with 18mg or 20mg. Nicotine salts are an excellent option here.
- As a rule of thumb in the UK:
- Nicotine Salts (10-20mg): Best for strong cravings, especially in 50/50 e-liquids with MTL/pod devices.
- Freebase (3-12mg): Ideal for MTL vaping with 50/50 e-liquids, or at lower strengths in high-VG e-liquids for sub-ohm/DTL setups.
- Average Smokers (10-15 cigarettes a day): A strength of 10mg or 12mg is a good middle ground.
- Light Smokers (fewer than 10 a day): Try 3mg or 6mg. You can always adjust if cravings persist.
- Quitting Nicotine Entirely: Nicotine-free vape juice (0mg) is available. It’s perfect for those who enjoy the act of vaping without the nicotine.
Nicotine Salts vs Freebase Nicotine
You'll encounter two main types of nicotine: freebase and nicotine salts.
- Freebase nicotine is the traditional form used in most e-liquids. It provides a noticeable "throat hit," which gets harsher as the strength increases. This makes it ideal for vapers using lower strengths (3mg-12mg).
- Nicotine salts are a more modern innovation. They are absorbed by the body faster and provide a much smoother vape experience, even at high strengths like 20mg. This makes them perfect for new vapers who were heavy smokers, as they deliver a quick nicotine fix without the overwhelming throat hit.
As a rule of thumb in the UK: salts (10–20 mg) + 50/50 in MTL/pods for strong cravings; freebase (3–12 mg) in 50/50 for MTL or lower strengths in high-VG for sub-ohm/DTL.
Vape Juice Flavours: Finding Your Match
Exploring flavours is one of the most enjoyable parts of vaping. Finding a taste you love can make all the difference in staying off cigarettes.
Flavour Categories
The vape-juice flavour variety in the UK is immense, but most fall into a few key categories:
- Tobacco Flavour E-Liquid: A popular starting point for ex-smokers, mimicking the familiar taste they're used to.
- Menthol Vape Juice: Cool and refreshing, ideal for former menthol cigarette smokers.
- Fruit Vape Juice: A huge category with everything from simple strawberry to exotic mango blends.
- Dessert Vape Juice: Indulgent flavours like custard, cake, and cookies for those with a sweet tooth.
Start with a flavour matching your old smoking preference (tobacco or menthol). Then, branch out to fruits or desserts once you're comfortable.
Flavour Fatigue and Rotation
Have you ever vaped a flavour so much you can no longer taste it? This is known as "vaper's tongue." It’s completely normal and temporary. The best way to combat it is to have two or three different flavours on rotation. Switching between a fruit and a dessert flavour, for example, keeps your taste buds engaged and prevents any one taste from becoming dull.
Device Compatibility and Vape Juice
The type of vape juice you choose must be compatible with your device. Using the wrong one can lead to poor performance, leaking, or burnt coils.
Buy UK-registered products from reputable retailers. Avoid illegal imports. These often exceed legal capacities or contain unknown contaminants.
MTL vs DTL Vaping
Your vaping style plays a big role here.
- Mouth-to-Lung (MTL): This style mimics smoking. You draw the vapour into your mouth first, then inhale. MTL devices, like pod kits, use less power and are best suited for 50/50 vape juice or nicotine salts.
- Direct-to-Lung (DTL): You inhale vapour directly into your lungs, creating large clouds. DTL vaping requires powerful, sub-ohm devices and thicker, high-VG e-liquid to function correctly.
Matching Vape Juice to Devices
Our technicians offer this simple advice on device compatibility for e-liquid:
- Pod Kits and Starter Kits: These low-wattage devices have small coils. They need thinner e-liquid to wick properly. Stick to 50/50 vape juice or nicotine salts. Using high-VG e-liquid will clog the coil and cause "dry hits"—a nasty burnt taste.
- Sub-Ohm Devices: These high-wattage kits are built for clouds. They have large wicking channels and low-resistance coils designed for thick liquids. Use high-VG e-liquid (70/30 or higher). A thin, 50/50 juice in a sub-ohm tank is likely to cause leaking and spitback.
Proper airflow is also important. More open airflow is for DTL vaping with high-VG juice, while tighter airflow suits MTL vaping with 50/50 liquids.
Tip: Prime new coils and start at the lower end of the recommended wattage. Match airflow (tight for MTL/50/50; open for DTL/high-VG) to avoid dry hits and extend coil life.
Health and Sensitivity Considerations
While vaping is recognised as significantly less harmful than smoking, it's not risk-free and some health risks remain (NHS, 2023). It's wise to be aware of potential sensitivities.
PG Sensitivity and Allergies
A small number of people are sensitive to Propylene Glycol (PG). Symptoms can include a sore or dry throat, skin irritation, or a persistent cough that doesn't feel like a typical "smoker's cough." If you suspect a PG sensitivity, the solution is simple: switch to a high-VG e-liquid. Many brands offer 80% VG or even 100% VG options specifically for this reason.
Practical Tips for a Smooth Experience
To ensure a comfortable vaping journey, our specialists recommend two things. First, stay hydrated. Both PG and VG can be slightly dehydrating, so drinking plenty of water helps prevent a dry mouth. Second, store your e-liquids in a cool, dark place. This preserves the flavour and nicotine, ensuring your vape juice stays fresh.
Budget vs Premium Vape Juice
In the UK, you can find e-liquid at every price point. What’s the difference?
Budget-Friendly Options
Shortfills are nicotine-free bottles with space for one or more nic shots. Because they are outside the scope of UK TRPR, they come in larger sizes at better value—just be sure to follow mixing guidance for safe, legal results.
Budget e-liquid options are perfect for everyday vaping without breaking the bank. Shortfill vape juices offer great value because they are usually nicotine-free. This means they fall outside the scope of UK TRPR (Tobacco and Related Products Regulations).
As a result, they come in larger bottle sizes and are priced more competitively. You can also add your own nicotine shot if needed. One of the most cost-effective choices is shortfill vape juice. These are large, nicotine-free bottles with space at the top to add a nicotine shot. They offer great value for sub-ohm vapers.

Premium Vape Juice Brands
Premium vape juice brands UK often use more complex flavour blends, resulting in a more nuanced and satisfying taste. While they cost more, many vapers find them worth it for special occasions or as a treat. They often provide a particularly smooth vape experience.
Conclusion
Choosing the right vape juice is a personal journey, but you're now equipped with the expert knowledge to find your perfect match. Remember to align your nicotine strength with your past smoking habits. Select a flavour you genuinely enjoy. Most importantly, match the PG/VG ratio to your device.
Don't be afraid to experiment. The goal is to find a combination that keeps you satisfied and away from cigarettes. Choose UK TRPR (TPD-derived) compliant e-liquids. Ensure quality and safety. Buy from trusted retailers like Vape Offers.
