4 Best 6-Burner Gas BBQs of 2025

The CosmoGrill Barbecue 6+1 Pro Gas Grill BBQ is the best 6-burner gas BBQ for entertaining. It’s large, looks impressive, yet remains easy to control and use.

This barbecue has six main gas burners, plus an additional side burner for cooking things in a pan or frying pan. Each burner can be individually lit, so you don’t have to use them all if cooking for fewer people. This makes this BBQ just as suitable for a couple’s midweek dinner as it is for family gatherings.

This BBQ has a cooking area measuring 77 x 42 cm, which provides enough space to cook for up to 18 people at one time – one of the reasons it’s such a good choice for entertaining guests! The double walled hood helps to maintain the interior temperature, and there’s a thermometer at the top so you can easily monitor the temperature without opening the lid. Once cooked, food can be transferred to the large warming rack at the top of the burner.

Despite the large size, this BBQ is relatively easy to manoeuvre. It’s fitted with four castor wheels so it can be rolled across hard surfaces. Also, it’s surprisingly lightweight for such a large BBQ, weighing 39 kg (which is less than some 3-burner BBQs!). Therefore, although you’ll need two people, it’s not impossible to carry up and down steps in multi-level gardens.

The practical features don’t stop with its manoeuvrability; this BBQ also has integrated storage. The spacious bottom shelf has doors and will keep condiments, plates and accessories safely tucked away. There are also two side tables (one of which conceals the side burner) that can be used to store items, or for food preparation.

This BBQ arrives flat packed, which isn’t uncommon for gas BBQs. Assembly takes around two hours as long as the instructions are followed closely. They’re pretty clear and easy to understand, which can’t be said for all flatpack assembly manuals!

In terms of overall quality, this BBQ is pretty good. In some places, the metal may be a little thinner than you might expect, but this will be an aspect that helps keep the weight down. Therefore, it’s a reasonable compromise when you consider the fairly easy manoeuvrability of such a large BBQ.

Cleaning the BBQ after use is relatively simple, with relatively flat grills that don’t catch too much dirt and a drip tray that assists with removing the fat.

Overall, this is a very practical and functional choice. The lighter weight means you won’t shy away from getting this BBQ out of the shed when you want to, and it’s also an excellent choice for cooking food for a lot of people. It’s one of the best 6-burner gas BBQs overall, and a great option for entertaining guests.

This Fire Mountain 6-Burner Gas BBQ is a good choice for those after a versatile and practical BBQ. It’s fitted with a combination grill and griddle cooking surface as well as a rotisserie. This makes it the best 6-burner gas BBQ for versatile cooking – you can cook a variety of different foods at once.

The grill side can be used for sausages and steaks, whilst the griddle area can be used to grill bacon or even make pancakes. On top of this, the detachable rotisserie (which is rare to find included with a BBQ) can cook whole poultry birds. The rotisserie turns on a motor so you don’t even need to worry about evenly cooking it yourself.

With a cooking area measuring 92.5 x 41.5 cm, this BBQ can easily cook for up to 20 people at once. The area is powered by six stainless steel burners, each controlled individually with piezo ignition, and they’re easy to light every time. There is also an additional side burner (just adding to this BBQs versatility!) that can be used to cook sauces and sides.

There is blue LED lighting surrounding the control dials, making it possible to see which are on, and to what level, from a distance – even at dusk. Additionally, the thermometer on the hood allows you to monitor the interior temperature without opening the lid.

Underneath the cooking area, there’s a large drip tray that catches any grease or fallen bits of food. The tray funnels the fat down into the centre, making it easier to clean after cooking.

Another benefit of this BBQ is that it’s very good quality. It’s made from stainless steel, enamel and cast iron. It’s sturdy and even looks like a premium model thanks to its sleek appearance and the blue LEDs. It comes with a protective cover included, which fits well, adding to the overall quality.

Although this BBQ is heavy, at 55 kg, it’s fitted with four castor wheels that make it easier to move across hard ground. Assembly is reasonably straightforward – the BBQ can be put together in around an hour depending on your familiarity with DIY.

To summarise, this BBQ is one of the best for versatility. It’s a premium model, so you do pay a little more for it, but the features and cooking options that you get in return are well worth the price – particularly if you’re passionate about cooking outdoors.

If you know the importance of a perfectly seared cut of meat, the Char-Broil Convective Series 640 B XL – 6 Burner Gas Barbecue will be the ideal BBQing companion. On top of this BBQs five main burners and one side burner, there’s an additional ‘sear zone’ burner.

The sear zone is powered using a 4.68 kW burner that reaches high temperatures even quicker. This means you can quickly cook meat on this part of the grill, sealing it without causing it to dry out or burn. It’s therefore one of the best 6-burner gas BBQs for anyone who likes to sear beef, poultry, pork or seafood.

The remaining burners can also be individually controlled, and each one has electronic ignition allowing you to light the burner at the push of a button. The temperature gauge on the hood means you’ll be able to monitor the interior temperature without opening the lid of the BBQ.

The additional side burner can be used for sauces and sides. This burner area has a lid so it can be covered when not in use. When it’s concealed, it can just be used as a regular side table. There are two side tables on this BBQ altogether.

With cast iron grill grates, this BBQ produces visible sear marks on food. Just be aware that these grills cannot be cleaned in the dishwasher as the coating may get damaged. Therefore, all of the parts of this BBQ have to be cleaned by hand.

In total, the cooking area measures 89 x 47 cm. The manufacturer states that this can cook for over 8 people, and I estimate it would be suitable for cooking for up to 20. The removable shelf above the cooking area can be used to keep food warm when it’s ready and it can also be used to toast rolls and buns if needed.

Weighing 63 kg, this BBQ is the heaviest option featured here. It’s fitted with four castor wheels, so it can easily be wheeled across hard surfaces, but it might be a bit of an ordeal to move across multi-level gardens. Two of the castor wheels lock, stopping the BBQ from rolling once it’s in position.

Assembly is the longest of any BBQ on this page. It takes between 2 – 4 hours, depending on your DIY experience. However, the end result is well worth this time investment – just don’t try to assemble it when you’re hosting a BBQ on the same day! There’s a hose and patio gas regulator included, so once the BBQ is up and running, you will at least be ready to go.

Not only is this one of the best 6-burner gas BBQs if you want to sear different meat, it’s also got a lot of other factors going for it. It can cater for a lot of people, it’s very powerful and it cooks food uniformly. You certainly get bang for your buck with this one.

Coming with a lot of useful, additional elements, this BillyOh Stainless Steel 6+1 Gas BBQ is the best 6-burner gas BBQ if you’re after value for money. Not only this, but it’s been designed and made by BillyOh in Nottinghamshire, by people who certainly know about the nuances of BBQing in the UK!

Before we get into the main specifications, I want to mention a few things that sets it apart from many other BBQs. It comes with a hose and gas regulator included, and is suitable for use with both butane and propane gas. There’s also a waterproof PVC cover included, to offer protection from the elements. All this, and yet it’s still cheaper than several BBQs featured here.

This BBQ has a split grill that makes cooking different food as easy as possible. One side is a cast iron searing plate, while the other is a porcelain cooking grid. The warming rack at the top can be used to keep cooked food warm. Additionally, there’s a side burner which provides an extra cooking space for side dishes or preparing sauces. The total cooking area measures 76 x 40 cm.

Like other BBQs on this page, this BillyOh BBQ has burners which can be individually controlled. Whether you’re cooking for just a couple of people or hosting a summer party, you’ll have full control over the cooking area, allowing you to cook different foods at the same time.

Other helpful features include a built-in thermometer that allows you to safely and accurately monitor the cooking temperature, a side table shelf and a storage cabinet underneath.

Weighing 40 kg, this BBQ is lighter than the majority of 6-burner gas BBQs on this page. It has four castor wheels, all of which are able to be locked in position to stop the BBQ from moving around.

In terms of assembly, you’re looking at around two to three hours with this model. It’s relatively straightforward, just slightly time consuming.

Overall, this is one of the best gas BBQs if you’re after value for money. It offers a lot of great features, including a grill/griddle cooking area and a side burner, plus it’s large enough to cater to a lot of people. The included cover, hose and regulator makes it better value than others on the market.
