A barbecue can be the centre of a relaxed family afternoon or a last-minute weekday dinner outdoors. The choice between a charcoal versus gas barbecue affects far more than flavour: it changes how quickly you can cook, how much preparation is involved and how often the BBQ is likely to come out of storage.
There is no single right answer for every garden. Charcoal suits people who enjoy the traditional ritual and smoky finish, while gas is often the practical choice for households that want reliable heat at the turn of a knob. The best option is the one that fits the way you genuinely cook outdoors.
Charcoal versus gas barbecue at a glance
A charcoal barbecue uses lumpwood charcoal or briquettes as its fuel source. Once the coals are glowing and covered in a light grey ash, food cooks over direct or indirect heat. It takes more time to set up, but it delivers the familiar barbecue aroma many people look for.
A gas barbecue runs from a refillable gas bottle, with burners that light using an ignition system. You can control the heat by adjusting individual burner knobs, much like cooking on a hob. It is quick, clean and particularly useful when you are feeding people at different times.
In simple terms, choose charcoal if flavour and traditional outdoor cooking are your priority. Choose gas if convenience, control and frequent use matter most.
Flavour: does charcoal really taste better?
Charcoal can add a smoky, slightly charred character to burgers, sausages, steaks and vegetables. This comes from cooking over hot coals and from meat juices or marinades hitting the heat source below. For many barbecue fans, that flavour and the slower build-up to cooking are part of the occasion.
Gas does not naturally create the same smoky profile. It does, however, produce excellent results when food is properly seasoned and cooked at the right temperature. A gas barbecue can also be fitted with a smoker box where suitable, allowing wood chips to add a little extra aroma.
The difference is noticeable, but it should not be overstated. A badly managed charcoal barbecue can leave food blackened outside and undercooked in the middle. A well-preheated gas barbecue can give chicken crisp skin, properly seared steaks and evenly cooked vegetables with much less guesswork.
A note on heat control
Gas has the advantage here. Multiple burners let you create a hot area for searing and a cooler area for gentler cooking. This is ideal for thicker cuts, chicken pieces and food that needs time without burning.
With charcoal, heat control takes more practice. You manage it by changing the amount and position of the coals, raising or lowering the grill where possible, and using vents to control airflow. It is rewarding once learned, but less forgiving if guests are already hungry.
Speed and ease of use
For a spontaneous meal after work, gas is hard to beat. Most gas barbecues are ready to cook in around 10 to 15 minutes, depending on the model and outdoor temperature. Turn on the gas, light the burners, close the lid and allow the grill to preheat.
Charcoal usually needs 20 to 40 minutes before it is ready, especially if you are lighting it without a chimney starter. You will also need to allow time for the coals to cool completely afterwards. This is not a drawback for everyone, but it makes charcoal less practical for a quick midweek meal.
If your barbecue will mainly be used for weekend gatherings, charcoal may be a good fit. If you picture grilling vegetables, halloumi or chicken several times a week through spring and summer, gas is likely to earn its space in the garden more often.
Initial cost and running costs
A basic charcoal barbecue is often the more affordable way to get started. Compact kettle-style models can offer plenty of cooking space for a small family without a large upfront spend. Charcoal barbecues also tend to have fewer mechanical parts, which keeps the design straightforward.
Gas barbecues normally cost more initially, particularly larger models with several burners, side shelves and storage space. You will also need to buy a compatible gas bottle, regulator and hose if they are not included. In return, you get a more flexible cooking appliance that can handle everything from quick kebabs to a full family meal.
Fuel costs depend on how often you cook and what you buy locally. Charcoal, firelighters and smoking wood can add up over a busy summer. A gas bottle can cover many cooking sessions, although the refill cost is higher in one go. For households that barbecue regularly, gas can be easier to budget for and less wasteful for short cooks.
Cleaning and maintenance
Neither type is maintenance-free, but gas is usually quicker to reset after dinner. Let the barbecue run on high for several minutes with the lid closed to burn off food residue, then brush the grates once they have cooled slightly. Empty grease trays regularly and check burners for blocked holes at the start of the season.
Charcoal creates ash, so the ash catcher or base needs emptying once the coals are fully cold. Grates still need brushing, and a deeper clean helps prevent old grease from affecting flavour. Never tip warm ash into a garden waste bag or plastic container.
A fitted cover is worthwhile for either style, particularly in the UK where a dry afternoon can quickly turn into rain. Store gas bottles upright outdoors in a well-ventilated place, away from direct heat. Keep charcoal dry in a sealed container so it lights properly when you need it.
Which barbecue size should you buy?
Think about the number of people you normally cook for, rather than the biggest gathering you might host once a year. A compact barbecue works well for two to four people and takes up less room on a patio. Families who regularly invite friends over may prefer a larger cooking area, especially if they cook meat and vegetarian food separately.
For gas, two burners are often enough for a small household, while three or four burners offer better zoning for family meals and entertaining. Side shelves are useful for plates and preparation, but check the overall width before buying. The barbecue needs a level, clear position with safe space around it.
For charcoal, a kettle barbecue with a lid is more versatile than an open brazier-style grill. The lid allows indirect cooking and helps retain heat, making it easier to roast a whole chicken or cook ribs slowly. Look for a sturdy ash catcher, adjustable vents and a grate that is easy to remove for cleaning.
Practical garden considerations
Position any barbecue on a stable, non-combustible surface and well away from sheds, fences, overhanging branches and garden furniture. Never use a barbecue in a greenhouse, gazebo, marquee, garage or other enclosed or partially enclosed space. Carbon monoxide and fire risk make this unsafe, even if the sides are open.
If your outdoor space is compact, gas may make life easier because there is no ash and less drifting smoke. Charcoal smoke can be bothersome for close neighbours, particularly while the coals are lighting. On the other hand, a small charcoal kettle can be easier to store than a full-size gas barbecue.
Families with young children should also consider stability. Choose a solid base, keep tools and hot surfaces out of reach, and create a clear no-play zone around the cooking area. Long-handled utensils and heatproof gloves are simple additions that make outdoor cooking safer.
When charcoal is the better choice
Choose charcoal if you enjoy cooking as part of the event, have time to light and tend the coals, and want the traditional smoky character. It is particularly good for occasional weekend use, smaller budgets and cooks who like experimenting with vents, two-zone heat and smoking wood.
Charcoal is also a sensible option where storage space is limited. A compact model can be covered and tucked away between uses, leaving more room for seating, planters or children’s outdoor play.
When gas is the better choice
Choose gas if you want to cook outdoors often with minimal preparation. It suits busy families, larger gatherings and anyone who prefers precise heat control. The ability to use separate burners is helpful when cooking a mix of burgers, corn, chicken and meat-free options at the same time.
Gas is the more practical all-rounder for many households, especially when the barbecue is treated as an extension of the kitchen during warmer months. When comparing models in the Garden & Outdoor Living collection, focus on usable grill space, burner layout, storage and build quality rather than choosing solely on the number of extra features.
Frequently asked questions
Is gas safer than charcoal?
Both are safe when used correctly outdoors, on stable ground and away from flammable materials. Gas requires regular checks of the hose, regulator and connections. Charcoal requires care when lighting, handling hot coals and disposing of ash. Never leave either barbecue unattended while lit.
Can you get a good sear on a gas barbecue?
Yes. Preheat the barbecue properly with the lid closed, then cook over the hottest burner area. Avoid overcrowding the grill, as this lowers the temperature and prevents good browning.
Is lumpwood charcoal better than briquettes?
Lumpwood generally lights faster and can burn hotter, while briquettes tend to offer a steadier, longer-lasting heat. Lumpwood is useful for quicker grilling; briquettes are often better for longer cooks. Whichever you choose, use barbecue-grade fuel rather than treated wood or household coal.
The most useful barbecue is not necessarily the one with the biggest grill or the strongest claim on the box. Pick the model you will be happy to set up, clean and use regularly, then make room for a few unhurried meals outdoors with the people you enjoy most.
