Choosing the best charcoal for your BBQ comes down to three things: what grill you own, what you’re cooking, and how long you need the heat to last. Most people never think past grabbing whatever bag is nearest the supermarket door, but the difference between cheap charcoal and the good stuff shows up the moment you taste the food. This guide covers every type of BBQ charcoal available in the UK, matches each one to the right grill and cooking style, and gives you the practical detail to spend your money well.
In short: lumpwood charcoal is the best all-round choice for most BBQ cooks. It burns hotter and cleaner than briquettes, lights faster, and produces less ash. Use premium lumpwood for kamado grills and offset smokers, standard lumpwood for kettle grills, and briquettes when you need a long, steady burn for overnight cooks. Avoid instant-light charcoal if flavour matters to you, and skip the lighter fluid altogether. A chimney starter and natural firelighters are all you need.

What Are the Main Types of Charcoal for BBQ?
There are five main types of charcoal for BBQ available in the UK, and each behaves differently on the grill. Picking the right one depends on what you’re cooking, how long you need the heat to last, and how much effort you want to put into fire management.
Lumpwood Charcoal
Lumpwood is pure carbonised hardwood with no binders or additives. It lights quickly (typically 15–20 minutes in a chimney starter), burns hot, and responds fast to airflow changes. That responsiveness makes it the go-to for grilling where you need to raise or drop temperature on the fly. The trade-off is a shorter burn time than briquettes and inconsistent piece sizes between brands, so you may open a bag to find a mix of fist-sized chunks and dusty fragments.
The wood species matters more than most people realise. Oak lumpwood burns longer and adds a subtle smoky flavour. Birch lights faster and burns slightly cleaner. Tropical hardwoods (often labelled “restaurant grade”) tend to be very dense, giving excellent heat output and long burn times. Look for bags that name the wood species rather than just saying “hardwood blend.”
Charcoal Briquettes
Briquettes are made from compressed charcoal dust, sawdust, and binding agents. Their uniform shape means predictable, even heat and longer burn times, often two to three hours from a single load. That consistency makes them a strong choice for low-and-slow cooks where you need the temperature to hold steady without constant attention.
The catch is that cheaper briquettes can contain chemical binders that produce an acrid smell during the first 10–15 minutes of burning. Always let briquettes ash over fully (covered in white-grey ash) before you put food on. Premium briquettes from brands like Weber and Heat Beads use natural starch binders, which burn much cleaner. We stock Heat Beads in the showroom, and they’re a reliable option for anyone doing long cooks on a kettle grill.
Instant-Light Charcoal Bags
Instant-light BBQ charcoal bags come pre-soaked in lighter fluid so you can set the bag itself alight. They’re convenient for a spontaneous park or beach cook, but the chemical accelerant can taint food flavour, especially if you start cooking before the fluid has fully burned off. The charcoal inside is usually lower-grade lumpwood with smaller pieces that burn out faster.
If convenience is your priority, instant-light charcoal works in a pinch. Just give it a full 20–25 minutes after lighting before you put any food on the grill, and accept that burn time will be shorter than a proper bag of lumpwood.
Coconut Shell Briquettes
Made from carbonised coconut husks, these briquettes burn very cleanly with minimal smoke and almost no flavour transfer. They’re popular in kamado grills and ceramic cookers because they produce far less ash than wood-based charcoal, which keeps bottom vents clear during long cooks. Weber’s coconut shell briquettes are a good example. Burn time is comparable to standard briquettes, but the near-neutral flavour profile means you can let smoking wood do all the flavour work without any competing taste from the fuel.
Binchotan and Specialist Charcoal
Binchotan is a Japanese white charcoal made from oak, typically used in konro-style grills for yakitori. It burns extremely hot with almost no smoke, producing a clean, intense sear. It’s expensive and not practical for everyday BBQ, but it’s worth knowing about if you’re exploring Japanese-style grilling. Big K produces a binchotan charcoal that’s available in the UK at a more accessible price point than traditional imports.

Which Charcoal Works Best in Your Grill?
The grill you own should drive your charcoal choice. Ceramic kamado grills have different airflow characteristics to steel kettle grills, and gravity-fed smokers have their own fuel requirements entirely. Here’s what we recommend based on testing across the 50+ grills on display in our Banbury showroom.
Kettle Grills (Weber, Napoleon, SNS Grills)
Standard lumpwood charcoal is the best match for kettle grills. The irregular piece sizes actually help here because they create natural gaps for airflow in the charcoal bed. For a typical weekend cook on a Weber kettle, fill your chimney starter about three-quarters full with lumpwood and you’ll have enough heat for 45–60 minutes of direct grilling. If you’re setting up a snake method for indirect cooking, briquettes are a better choice because their uniform shape stacks more predictably.
Kamado Grills (Big Green Egg)
Kamado grills are designed to run on lumpwood charcoal, and using the right fuel makes a noticeable difference. Premium, large-chunk lumpwood is ideal because it allows good airflow through the fire basket and burns cleanly in the restricted-oxygen environment of a sealed ceramic cooker. Big Green Egg produces its own lumpwood in three blends: Oak & Hickory (the deepest, most characterful flavour), Canadian Maple (subtly sweet, great for seafood and poultry), and Eucalyptus (neutral, letting smoking wood shine).
Avoid small or dusty lumpwood in a kamado. Tiny fragments can clog the bottom vent and choke airflow, making temperature control difficult. Coconut shell briquettes also work well in kamado grills, producing less ash and keeping vents clear during longer sessions.
Offset Smokers (Workhorse Pits, Cactus Jack)
Our range of offset smokers can run on lumpwood, briquettes, or a combination of both, supplemented with smoking wood splits or chunks. Many experienced offset users build a base fire with briquettes for their steady heat output, then add lumpwood or wood chunks for flavour. If you’re running an overnight brisket cook, a charcoal basket loaded with briquettes and a few wood splits gives you the most stable temperature with the least fiddling.
Gravity-Fed Smokers (Masterbuilt Gravity Series)
Gravity-fed smokers like the Masterbuilt Gravity Series use a vertical charcoal hopper, so fuel size matters. Large, irregular lumpwood pieces can bridge across the hopper and stop feeding properly. Briquettes work best in gravity-fed designs because their uniform shape flows smoothly down the chute. We’ve found that a mix of briquettes in the hopper with a couple of smoking wood chunks dropped in every hour gives excellent results on the Masterbuilt Gravity Series 800.
Portable and Camping BBQs
For a portable grill, convenience wins. Smaller BBQ charcoal bags of good-quality lumpwood (3–5 kg) are easier to transport than bulk bags. If you’re heading to the beach or park and want the least fuss, instant-light bags do the job acceptably — just manage your expectations on burn time and flavour depth. A better option is a small bag of lumpwood and a handful of natural firelighters packed in a resealable bag.
What’s the Best Charcoal for BBQ Cooking Styles?
Your cooking method matters just as much as your grill type. A hot sear on a ribeye steak needs different fuel characteristics to a 12-hour brisket smoke.
Hot-and-Fast Grilling (Steaks, Burgers, Vegetables)
Lumpwood charcoal is the clear winner for high-heat grilling. It reaches searing temperatures faster than briquettes and responds quickly when you open or close vents to adjust the heat. For steaks, load your chimney starter fully, let the charcoal ash over, then spread it in a single layer across your grill for an even, intense heat bed. Oak and tropical hardwood lumpwood are particularly good for searing because they burn at the highest temperatures.
Low-and-Slow Smoking (Brisket, Pulled Pork, Ribs)
Low-and-slow cooks need fuel that holds a consistent temperature for hours without constant top-ups. Briquettes are the traditional choice, and methods like the minion (placing unlit briquettes around lit ones so they ignite gradually) can give you six or more hours of stable heat. You can also use lumpwood for low-and-slow, but you’ll need to refuel more often. Many competition pitmasters use a briquette base for longevity with lumpwood or smoking wood chunks added periodically for flavour.
Indirect Roasting (Whole Chicken, Joints, Sunday Roast)
For indirect roasting, where you place food away from the coals and cook with convection heat, either lumpwood or briquettes work well. The key is a two-zone setup: pile charcoal on one side of the grill and cook on the other. Briquettes give a more predictable heat in this scenario, but lumpwood imparts a nicer smokiness. A drip tray under the food catches juices and keeps your grill clean.
Pair your charcoal with the right wood fuel and firelighters for the best results on every cook.
How Do You Spot Good-Quality Charcoal?
The difference between a premium bag and a budget one becomes obvious the moment you open them. Here’s what to check before you hand over your money.
- Piece size consistency: Good lumpwood should contain mostly fist-sized or larger pieces. A bag full of small fragments and dust means lower-quality carbonisation and more waste. Pick the bag up and feel its weight relative to volume, heavy bags with large pieces are a good sign.
- Low dust and fines: Shake the bag gently. If you can hear a lot of loose, rattling small pieces, expect more dust and less usable charcoal. Some premium brands sieve their lumpwood to remove fragments before bagging.
- Named wood species: Bags labelled with a specific wood (oak, birch, beech, quebracho) are usually better quality than those simply marked “mixed hardwood.” The wood type also tells you about burn characteristics.
- No chemical smell: Open the bag and have a sniff. Quality charcoal smells like wood or has almost no scent at all. A chemical, petroleum, or acrid smell means additives or poor carbonisation.
- Sustainability certification: Look for FSC (Forest Stewardship Council) or Woodsure certification. British-made lumpwood from coppiced woodland is one of the most sustainable fuel options available.
How Should You Light Charcoal Properly?
The way you light charcoal matters for both safety and flavour. A chimney starter is the single best investment any charcoal griller can make, and natural firelighters are all you need to get it going.
Using a Chimney Starter
A chimney starter is a metal cylinder that holds charcoal above a chamber for firelighters. Light two or three natural firelighters in the bottom chamber, fill the top with charcoal, and wait 15–20 minutes until flames are licking over the top coals. Then pour the lit charcoal into your grill and arrange it for your cook. This method is faster, more reliable, and produces zero chemical taste compared to BBQ charcoal lighter fluid.
Natural Firelighters vs Lighter Fluid
Natural firelighters made from wood wool or wax are odourless once burned and leave no residue on your food. BBQ charcoal lighter fluid, by contrast, is a petroleum-based accelerant that can leave a chemical taste if it hasn’t fully burned off before you start cooking. We sell firelighters in the showroom, and they’re the simplest way to get a chimney started in under a minute. If you’ve been using lighter fluid, try switching to natural firelighters for one cook and you’ll taste the difference immediately.
Electric Charcoal Starters
Electric starters are heating elements you bury in your charcoal pile and plug in for 8–10 minutes. They work well and produce no chemical taste, but they need a power source and are less practical for outdoor or portable setups. For most UK garden situations, a chimney starter is more versatile.
How Much Charcoal Do You Actually Need?
This is one of the most common questions we get in the showroom. The answer depends on your grill size, cook type, and how often you fire up. Here’s a practical guide.
Estimates based on typical UK conditions. Actual usage varies by grill efficiency and weather.
| Cook Type | Grill Type | Charcoal Needed | Approx. Cost |
|---|---|---|---|
| Quick grill (burgers, sausages) | Kettle / portable | 1–1.5 kg lumpwood | £1.50–£4.00 |
| Indirect roast (whole chicken) | Kettle / kamado | 2–3 kg lumpwood | £3.00–£6.00 |
| Low-and-slow (pulled pork, 6–8 hrs) | Kamado / smoker | 4–6 kg briquettes or lumpwood | £4.00–£8.00 |
| Full brisket (12+ hrs) | Offset / gravity-fed | 8–12 kg briquettes + wood | £8.00–£15.00 |
For regular grillers, buying BBQ charcoal bags in bulk (10 kg or larger) brings the cost per cook down significantly. A 10 kg bag of quality lumpwood typically covers five to eight standard grilling sessions on a kettle, making it far better value than grabbing small bags each time.
Stock up on charcoal, smoking wood, and firelighters before the season hits, bulk bags save you money on every cook.
How Should You Store Charcoal in the UK?
Charcoal absorbs moisture like a sponge, and damp charcoal is a nightmare to light. If you want your charcoal for the BBQ to perform well every time, proper storage in the UK’s climate makes a real difference.
Keep charcoal off the ground and in a dry spot. A garage shelf, shed, or covered storage area all work well. If the bag has been opened, fold the top over tightly and clip it shut, or transfer the charcoal into a plastic bin with a lid. Even a heavy-duty bin liner works in a pinch. The goal is simply keeping moisture out.
If your charcoal does get damp, spread it out on a dry surface (a tarp in the sun is ideal) for a few hours before use. Damp charcoal will still light eventually, but it takes much longer and throws off excessive smoke during the initial phase. You’ll hear a hissing, steaming sound as moisture escapes, and the temperature will stay lower until it dries out on the grill.
Is UK-Made Charcoal Better Than Imported?
Both can be excellent, but they have different characteristics. British lumpwood is typically produced from coppiced woodland (oak, birch, ash) in smaller batches. It supports local forestry management, has minimal transport miles, and often carries Woodsure or FSC certification. Piece sizes can be less uniform, but the flavour is lovely.
Imported charcoal from South America (quebracho), Africa (mixed hardwood), or Eastern Europe (birch) is often denser and available in larger piece sizes, which suits kamado grills and longer cooks. Restaurant-grade imported lumpwood can offer outstanding burn times and heat output. The trade-off is the carbon footprint of shipping, though many imported charcoals come from sustainably managed plantations or invasive species.
Our take: buy the best quality you can for your grill type, regardless of origin. If sustainability is a priority, look for FSC-certified products. We carry both British-made and imported charcoal in the Banbury showroom so you can compare them side by side.
Charcoal Brands We Stock and Recommend
We test every charcoal product before adding it to our range. Here are some of the charcoals for BBQ that we carry and what they’re best suited for.
- Big Green Egg Charcoal: Available in three blends — Oak & Hickory (rich, deep flavour), Canadian Maple (subtly sweet), and Eucalyptus (neutral, clean burn). Large chunk sizes designed for Big Green Egg fire baskets, but works well in any kamado.
- Heat Beads: Australian-made briquettes with natural starch binders. Excellent burn time (up to 4 hours), very consistent temperature, and minimal chemical odour. Our top pick for briquettes.
- Weber Charcoal Range: Weber produces both lumpwood (a beech, hornbeam, birch, and oak blend) and coconut shell briquettes. The coconut briquettes are particularly good for low ash output and a clean burn.

Frequently Asked Questions
How much does a typical charcoal BBQ session cost to run?
A standard weeknight grill on a kettle uses roughly 1–1.5 kg of lumpwood, costing between £1.50 and £4.00 depending on the brand. A full low-and-slow brisket cook can use 8–12 kg, costing £8–£15. Buying in 10 kg bags or larger cuts the per-session cost noticeably.
Can I use charcoal in a pizza oven?
Some pizza ovens accept charcoal, but most wood-fired models like the Gozney Dome are designed for kiln-dried hardwood or gas. Charcoal works well in kamado-style pizza setups (Big Green Egg with a pizza stone), where it provides the intense heat needed to cook a pizza in 60–90 seconds.
Is it safe to cook directly on charcoal (dirty grilling)?
Cooking food directly on hot coals is a legitimate technique used by professional chefs for steaks, flatbreads, and vegetables. The key is using high-quality, additive-free lumpwood that has fully ashed over. Avoid briquettes for dirty grilling because their binders can leave residue. Big Green Egg actively encourages this method with their charcoal range.
How do you safely dispose of used charcoal ash?
Let ash cool completely for at least 48 hours in a metal container. Never put warm ash in a plastic bin or near combustible materials. Once fully cooled, wood charcoal ash (not briquette ash) can be scattered lightly on garden soil as it contains potassium and other minerals. Briquette ash should go in general waste.
Can you relight partially used charcoal?
Close all vents on your grill after cooking to starve the fire of oxygen. The remaining charcoal will extinguish and can be reused next time. Top up with fresh charcoal and relight as normal. This is one of the easiest ways to reduce waste and get better value from premium lumpwood.
