CosmoGrill Platinum 8 Burner Review UK 2026
Quick verdict
Score: 9.0/10
Best for: Regular garden barbecuing for family and guests
Not for: Anyone short on storage space, or wanting charcoal flavour from a pure gas model
Bottom line: A practical gas barbecue (6 burners + 2 side burners) for outdoor cooking.
Overall, the CosmoGrill Platinum 8 Burner is a practical choice for buyers who want more cooking capacity than most basic BBQs, because it uses 6 main burners plus 2 side burners on a gas grill. Reviewers note it suits larger family meals and batch cooking, with separate side burners supporting prep or smaller pans. This gas barbecue also comes with a waterproof cover, which helps with day-to-day storage, but weather protection depends on proper fitting. As a cosmogrill gas bbq, it is less ideal for small patios needing compact space, because the layout is extensive.

Style and Setting
After the key specifications, the next consideration is how the CosmoGrill fits into day-to-day outdoor cooking, focusing on both appearance and practical use. The stainless steel finish and the eight-burner layout (six main burners and two side burners) create a kitchen-style look that suits patios and gardens. The main cooking area is designed for preparing multiple items at once, while the two side burners provide space for extra pans when running sauces alongside the main meal. A waterproof cover helps protect the barbecue when it is stored outside, although suitable storage space is still required. In day-to-day use, it is a gas barbecue for outdoor use only, and it needs routine attention to prevent grease build-up that can contribute to flare-ups.
Size and Seating
Size and seating begin with the practical reality of an eight-burner layout, comprising six main burners plus two side burners. The extra cooking zones enable multiple tasks at once, which suits larger groups more than small patios. On smaller decks, the broader footprint may crowd walkways, so placement matters. If used regularly, the layout accommodates larger dinners, while occasional use may make the grill feel more substantial than necessary.
Materials and Build
With an eight-burner configuration designed for heavy-duty outdoor cooking, the gas barbecue is positioned as a stainless steel barbecue, which generally supports everyday weather resistance and straightforward wipe-down cleaning. A waterproof cover is included for outdoor storage, helping protect the grill when it is not in use. After cooking, owners can keep surfaces clean by wiping down, since grease and residues do not bond as readily to stainless.
Comfort and Features
Comfort and Features cover the practical setup for outdoor cooking on the CosmoGrill. The cooking system is arranged around 6 main gas burners plus 2 side burners, supporting parallel tasks such as grilling on the main burners while using the side burners for work like heating sauces or warming sides. The package includes a waterproof cover to help protect the unit during outdoor storage.
Who Is This For?
This BBQ suits buyers who want substantial cooking capacity in a single unit, particularly families or frequent hosts who regularly grill for more than a couple of people. It is designed for people choosing the gas barbecue, which features 6 burners plus 2 side burners, with gas operation and a waterproof cover. The extra burners are useful when multiple items need cooking at the same time, or when side dishes must be cooked separately from the main food. Frequent outdoor use may also make use of the cover for storage. For shoppers looking for a compact setup, alternatives may be more suitable.
Where to Buy in the UK
Where can buyers in the UK find the CosmoGrill Platinum 8 Burner? It is typically sourced through UK retailers that stock The CosmoGrill outdoor gas BBQs, including those focused on garden equipment. It is listed as a "Gas barbecue 8 Burner 6+2 Gas Barbecue Grill with Waterproof Cover", so buyers should confirm the "6+2" burner layout and that a waterproof cover is included before ordering. Listings may be available online only or with click-and-collect, so delivery timing and dispatch dates should be checked when placing an order, as availability can change.
Frequently Asked Questions
Is the CosmoGrill worth it?
For regular garden barbecuing for family and guests, the gas barbecue (a 6 burners + 2 side burners gas BBQ) does the job. Whether it suits you depends on how many you cook for, your space and how often you grill. Check the current Amazon UK price, as barbecues are heavily discounted outside the summer peak.
How many burners does this gas barbecue have?
The CosmoGrill is a 6 burners + 2 side burners model. As a rough guide, 2 burners suit couples and small families, 3 to 4 burners suit most households, and 5 or more suit regular entertaining. More burners also mean better zone control - you can run one side hot for searing and leave another cooler for indirect cooking, which is how you avoid burnt outsides and raw middles.
What fuel does the CosmoGrill Platinum 8 Burner use?
The gas barbecue runs on gas (LPG). You'll need a gas bottle - typically patio gas or propane - plus the correct regulator and hose, and these are usually sold separately, so factor that into the cost. Gas gives instant heat, precise control and quick cleanup compared with charcoal.
What features does this gas barbecue have?
The CosmoGrill offers cover included. Match the features to how you actually cook.
How do you look after the gas barbecue?
Brush the grates while still warm after each cook, and empty the grease tray regularly - a build-up is the most common cause of flare-ups. Give the burners an occasional check for blockages. Crucially, use a cover and store it somewhere dry over winter, as rust is what kills most gas barbecues long before the burners fail. Always turn the gas off at the bottle after use.
