Style and Setting
Built for everyday outdoor cooking, this gas barbecue is a built-in style gas BBQ, suited to outdoor kitchen setups where the grill is installed as part of a fixed run rather than standing freestanding. It comes in a black finish with an included 600D Oxford weatherproof cover for year-round storage, although the level of protection and how well it fits depends on the owner's own cover method. The design focuses on a lid with a built-in thermometer, a steel warming rack, and a side burner for extra tasks such as reheating or using smaller pans. For best results, the outdoor space should allow safe gas connections and provide steady access around the control area.
Size and Seating
With an outdoor kitchen setup, practical size and usable seating are important because the grill's layout affects how many dishes can be cooked at once and how comfortably people can gather nearby. The CosmoGrill is designed with six main burners plus a side burner, which supports multi-person cooking when the cooking space is separated into zones. A steel warming rack is included for keeping food warm, reducing the need to serve immediately. Seating arrangements can also depend on the chosen built-in position, as clearance is required for the lid and the control area.
Materials and Build
The grill's construction focuses on durability where it matters, and several details remain unconfirmed based on the available information. It is an in-built gas BBQ, supplied with a black 600D Oxford weatherproof cover, indicating cloth protection from rain and dust when stored. The warming rack is identified as steel, so it should resist warping better than thinner wire-style racks. A built-in thermometer is present, but the information does not specify lid material thickness, frame gauge, or coating type. The 6+1 burner layout is supported by internal components that are not described, so long-term durability depends on parts that are not stated.
Comfort and Features
Comfort and features focus on day-to-day ease with this built-in gas BBQ, which has 6 burners plus a side burner. It includes a steel warming rack, a built-in thermometer, and push-button (piezo) ignition. Day-to-day operation is straightforward: press the ignition, light the main burners, then adjust the heat as required. The lid thermometer helps monitor cooking temperatures without repeatedly lifting the lid, which can disrupt cooking. The steel warming rack provides a place to hold food while other items are grilling. The side burner is designed to add extra cooking flexibility for items such as sauces.
Who Is This For?
This built-in The gas barbecue is a good fit for people who want a straightforward, multi-burner gas setup for regular cooking, especially if they value having a lid thermometer and a separate side burner. It suits households that host meals often, because six burners plus the side burner make it easier to cook several items at once. With its built-in design, it also appeals to people planning a fixed outdoor kitchen rather than moving the barbecue. The included weatherproof cover can help protect it when not in use, though storage conditions still matter. Buyers looking for portable convenience may find the built-in approach less suitable.
Where to Buy in the UK
For UK shoppers, the CosmoGrill is typically sourced through mainstream retail outlets and UK BBQ specialists that stock The gas barbecue's built-in gas range. A practical approach is to compare product listings. In-store buyers can inspect the 600D Oxford weatherproof cover and black finish, while online buyers should confirm delivery for a built-in layout.
Frequently Asked Questions
Is the CosmoGrill Pro Deluxe 6 worth it?
For regular garden barbecuing for family and guests, the CosmoGrill (a 6 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 have?
The CosmoGrill is a 6 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 gas barbecue use?
This 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.
Is the CosmoGrill portable?
The CosmoGrill Pro Deluxe 6 is a built-in model. It's built to live in the garden rather than travel, usually with wheels so you can reposition it on the patio. Check the footprint against your space, and plan to cover or store it over winter to prevent rust.
What features does the gas barbecue have?
This gas barbecue offers side burner, warming rack, push-button ignition, lid thermometer. A side burner is genuinely useful for sauces, onions or keeping a pan warm without going indoors. A warming rack holds cooked food while the rest finishes. A lid thermometer lets you cook with the lid down, which is essential for anything thicker than a burger. Match the features to how you actually cook.
How do you look after the CosmoGrill?
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.
