Style and Setting
In a typical UK outdoor kitchen setting, the gas barbecue+1 Series is set up to separate main cooking from side preparation. It uses four main burners plus one separate side barbecue burner, and it is sold as a 4+1 BBQ with a cover and storage. The layout suits patios and garden runs where a clear workflow helps keep main pans or grills central while side tasks such as warming or prepping happen off to one side. Storage support helps keep essentials nearby.
Size and Seating
For outdoor cooking plans, the CosmoGrill+1 Series includes a four-burner main cooking area plus a separate side barbecue burner, so seating and prep space should match how food is handled. The four-burner layout allows simultaneous grilling for different items at the same time. The side burner can be used for sauces or warming to reduce the need to move between stations.
Materials and Build
Materials and build quality determine how stable the gas barbecue+1 Series feels during cooking, and how well it holds up outside. The 4+1 gas BBQ has four main burners plus a side barbecue burner, but the product title does not specify the frame material, cooking-plate type, or metal thickness. It includes storage and a cover, indicating it is intended to be protected when weather changes, although the cover material and fit are not stated. During setup, buyers should check panel alignment, handle tightness, and how the cover seats over the cooking area. Strength and longevity depend on these unlisted material details.
Comfort and Features
Comfort and Features covers how easy this gas barbecue+1 Series is to use during day-to-day grilling, and how useful the extra controls are away from the main burners. It includes four main burners for direct grilling, plus a separate side barbecue burner intended for tasks such as warming sauces. The controls are positioned so heat can be adjusted while staying focused on the primary cooking zone. Included storage and a cover support routine handling and help keep outdoor areas tidy. Using the side burner adds versatility, although it also requires additional attention when cooking is in progress.
Who Is This For?
The CosmoGrill 4+1 Series suits buyers who want a main cooking area served by four gas burners, plus an extra side barbecue burner for tasks that run alongside the main grill. The four burners make it easier to cook at different temperatures for small groups. The side burner also supports side dishes without using the main cooking zones. This model is less suitable for those who prefer fewer heat sources and simpler control, since extra burners add more elements to manage. Included storage and a cover help when space is limited and when storing the barbecue between uses.
Where to Buy in the UK
Where can buyers find the CosmoGrill+1 Series Gas BBQ in the UK, and what should they check before paying? Shoppers typically start with major UK retailers online, including Amazon UK, John Lewis, Currys, AO, and Argos, plus garden and outdoor-focused sellers such as B&Q, Homebase, Wickes, The Range, and Wayfair. Before purchase, confirm the listing matches "4+1" as 4 main burners plus a separate side burner, and check that it includes both storage and a cover, as these items may vary between sellers. Delivery terms, returns, and gas compatibility should be reviewed on each listing, since the required bottle, regulator, and hose details are not stated in the title. Photos should be checked for fit and finish, and the burner count value should be compared carefully because it directly affects cooking capacity and layout.
Frequently Asked Questions
Is the gas barbecue+1 Series worth it?
For regular garden barbecuing for family and guests, the CosmoGrill+1 Series (a 4 burners + 1 side burner 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 the gas barbecue+1 Series have?
This gas barbecue+1 Series is a 4 burners + 1 side burner 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+1 Series use?
The CosmoGrill 4+1 Series 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.
How do you look after the gas barbecue+1 Series?
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.
