The Ultimate UK Vaping Guide for Beginners (2025 Edition)
Vaping has seen an incredible rise in popularity across the UK over the past year. Every day, more smokers are making the switch from traditional cigarettes to e-cigarettes. With so many new vapers starting their journey, it’s natural to have questions — from choosing your first vape to understanding how it all works.
In this complete guide to vaping, we’ll cover everything you need to know — from the basics and how to get started, to choosing the right vape juice and keeping your device in perfect condition.
What Is a Vape and How Does It Work?
A vape (or e-cigarette) is an electronic device that heats a liquid — called e-liquid or vape juice — to produce an inhalable vapour. Most e-liquids contain nicotine, which helps reduce cravings for traditional cigarettes.
A standard vape has three main components:
-
Battery: powers the device.
-
Tank or Pod: holds the e-liquid.
-
Coil (or Atomiser): heats the e-liquid and turns it into vapour.
When you inhale or press the activation button, the battery heats the coil, vaporising the liquid into a smooth mist that you then inhale.
How to Choose Your First Vape Kit
Starting out can feel confusing, as there are so many options. But most vape kits fall into two simple categories:
1. Disposable Vapes
-
Pre-filled, pre-charged, and ready to use straight from the box.
-
Designed for single use — once the liquid or battery runs out, the device is discarded.
-
Best for short-term or occasional use.
2. Refillable Vape Kits
-
Can be recharged and refilled with your preferred e-liquid.
-
More cost-effective and eco-friendly in the long run.
-
The coil or pod will need replacing periodically.
If you’re new to vaping, a starter kit is ideal. These kits are simple, safe, and affordable — perfect for beginners who want a straightforward experience.
When choosing your first device, consider your lifestyle:
-
Spend long hours outdoors? Choose a long-battery-life vape.
-
Want to replicate the feel of a cigarette? Try a mouth-to-lung (MTL) kit.
-
Prefer clouds and customisation? Move towards direct-to-lung (DTL) or sub-ohm kits later on.
Pod Mods and Advanced Vape Kits
Once you’ve mastered the basics, you might want a device with more control and power.
Pod Vape Systems
Pod systems replace the traditional tank with a pod and come in two main types:
-
Open Pod Systems: refillable pods with replaceable coils.
-
Closed Pod Systems: disposable pods (either prefilled or refillable with a fixed coil).
Pod vapes are popular because they’re compact, convenient, and mess-free — perfect for vapers who want an easy yet high-quality experience.
Advanced Vape Kits
For the more experienced user, advanced vape kits offer complete customisation.
They typically include:
-
Adjustable wattage and airflow.
-
Multiple vaping modes.
-
Sub-ohm capabilities for bigger clouds and stronger flavour.
These kits are best for those who already understand the fundamentals of vaping and want to fine-tune their experience.
Mechanical Mods and Rebuildables
Mechanical mods (mech mods) are unregulated metal tube devices that send battery power directly to the coil — no circuit boards, no safety features. They provide complete control but require knowledge of Ohm’s Law, battery safety, and coil building.
Types of rebuildables include:
-
RDA (Rebuildable Dripping Atomiser): manually drip e-liquid onto the coil for maximum flavour.
-
RTA (Rebuildable Tank Atomiser): similar to an RDA but with a tank for added convenience.
⚠️ Important: Mech mods are for experienced users only. Used incorrectly, they can be dangerous.
Box Mods Explained
A box mod is the powerhouse of a vape setup — the main unit that holds the battery and controls power output.
Advantages of box mods include:
-
Compatibility with a wide range of tanks and pods.
-
Choice of internal or removable batteries (single, dual, or even triple 18650s).
-
More advanced functions such as variable wattage and temperature control.
Leading manufacturers like VooPoo, Smok, and Geek Vape continue to innovate, offering reliable, high-performance mods for every vaping style.
How to Choose a Vape Juice (E-Liquid)
Vape juice, also called e-liquid, is made from Propylene Glycol (PG), Vegetable Glycerin (VG), flavourings, and sometimes nicotine.
PG vs VG — What’s the Difference?
-
High-PG Liquids – Thinner, provide a stronger throat hit, and are ideal for beginner or MTL vapes.
-
High-VG Liquids – Thicker, smoother, and better for sub-ohm or DTL vaping with larger clouds.
Nicotine Strength Guide
| Smoking Habit | Recommended Nicotine Strength |
|---|---|
| Light / Social Smoker | 3–6 mg/ml |
| Moderate Smoker (10–15 per day) | 6–12 mg/ml |
| Heavy Smoker (20+ per day) | 16–20 mg/ml |
You can also find nicotine-free (0 mg) options if you’re trying to quit completely.
Flavours
There are thousands of flavours available, from classic tobacco to fruity blends, minty menthols, and sweet desserts. Try a few and find what suits your taste best — everyone’s preference is unique.
How to Vape Safely
Vaping should only be used as an alternative to smoking, not as a casual hobby for non-smokers. Nicotine is addictive, so if you don’t already use it, avoid nicotine-based products.
To use your vape:
-
Press the power button 3–5 times to turn it on.
-
Prime your coil with a few drops of e-liquid and let it sit for a minute.
-
Fill your tank or pod.
-
Inhale — either using the button or by drawing directly, depending on the device.
-
MTL (Mouth-to-Lung): draw vapour into your mouth, then inhale into your lungs (like smoking).
-
DTL (Direct-to-Lung): inhale the vapour straight into your lungs for a fuller, smoother hit.
Charging, Refilling, and Maintenance
Charging Your Vape
Use the cable provided (USB or USB-C) and plug into a suitable outlet. Always monitor charging and unplug once full to avoid overcharging. For removable batteries, use a dedicated battery charger.
Refilling Your Vape
Locate the refill port (usually beneath a rubber plug or sliding top). Gently insert the nozzle and fill slowly to avoid spillage. Do not overfill.
Cleaning and Priming
-
Remove the coil before cleaning your tank with warm water.
-
Never use soap — it can leave residue.
-
Dry thoroughly before reassembling.
-
Always prime new coils to extend their lifespan and prevent burning.
Common Vaping Questions (UK)
How old do you have to be to vape in the UK?
You must be 18 or over to buy or use a vape. Selling vaping products to anyone under 18 is illegal.
Can vaping set off a smoke alarm?
It can, depending on the alarm type. To reduce the risk, exhale away from detectors and vape in well-ventilated areas.
How many puffs of a 20mg vape equal one cigarette?
Roughly 10–15 puffs deliver a similar nicotine level to one cigarette, though this varies by device and user.
How do I open a vape juice bottle?
Push down and twist anticlockwise — bottles are fitted with child-resistant caps.
How should I dispose of a vape?
Do not bin your vape at home. Take it to a recycling point or return it to a retailer that follows WEEE recycling regulations.
Can you recharge a disposable vape?
No — disposable vapes are single-use and not designed for recharging. For a rechargeable option, try prefilled pod kits, which are reusable and just as convenient.
Final Thoughts
Vaping is a modern, effective way to move away from smoking, offering flexibility, flavour, and control over nicotine intake. Whether you’re just starting or upgrading to an advanced kit, the key is to vape safely, maintain your device, and find what works best for you.
