CosmoGrill Hybrid 4 Burner DUO Review UK 2026
Quick verdict
Score: 8.9/10
Best for: Grilling on the go - camping, picnics, balconies and small patios
Not for: Cooking for a crowd - the grill area is limited
Bottom line: A practical gas barbecue (3 burners + 1 side burner, hybrid gas + charcoal) for outdoor cooking.
The CosmoGrill Hybrid 4 Burner is a practical dual-fuel BBQ choice, because it combines gas cooking with charcoal smoking in a single unit. This gas barbecue review UK notes the setup brings together fast heating from gas with the option to add charcoal for a richer smoke flavour. It suits home and garden parties, with a built-in thermometer and a warming rack for keeping food ready, but the dual approach requires more attention since switching cooking methods changes airflow and timing.

Style and Setting
For outdoor cooking setups that need flexibility, the CosmoGrill suits patios, gardens, and events where the cooking method may change during the day. Its dual fuel design, using gas and charcoal, lets a household vary flavour without switching equipment. The foldable, portable build supports storage when the season ends. A lid thermometer helps with more careful cooking control by allowing the temperature to be checked during use rather than guessed. A warming rack provides additional staging space.
Size and Seating
With the cooking setup able to adapt to changing plans, seating and serving capacity depends on the available grate area and how many heat zones are used. The gas barbecue uses 3 main burners plus a side burner, along with a warming rack, which supports staged cooking such as searing on one area while keeping food warm on the rack. For group meals, this layout suits small to medium gatherings. Servings per person therefore cannot be stated as a fixed number.
Materials and Build
The CosmoGrill is described as a hybrid outdoor barbecue designed to cook with both gas and charcoal, so the main cooking chamber and base need heat-resistant materials suitable for two different fuel modes. The build features a lid with a built-in thermometer and includes a warming rack, supporting a typical roasting and holding layout. The unit is also described as portable and foldable, indicating the frame relies on secure joints for movement and storage (not stated). Overall, the materials are positioned as suitable for outdoor durability, although specific construction materials, thicknesses, and heat-rated components are not detailed.
Comfort and Features
Comfort and Features focus on how the gas barbecue supports day-to-day outdoor cooking as a dual fuel unit that runs on both gas and charcoal. It features 3 burners plus 1 side burner, a lid with a built-in thermometer to help gauge heat while grilling or smoking, and a warming rack for resting food during parties. The foldable, portable design supports easier storage and transport, though care is needed to keep parts aligned when set up.
Who Is This For?
Who should buy the CosmoGrill Hybrid 4 Burner depends on how someone plans to cook outdoors, because it uses a dual fuel approach that combines gas grilling with charcoal smoking. It suits people who want the speed and control of gas for everyday cooking, while adding charcoal for smoky flavour. Hosting garden party meals or cooking for multiple people is a good fit for the 4 main burners plus a 1 side burner, along with additional cooking space provided by a warming rack for holding food. It also suits buyers looking for an outdoor, portable setup, although the charcoal component adds extra steps around lighting and cleanup. It may not suit strict minimalists, because a hybrid gas-and-charcoal grill involves more process than a gas-only model, including managing charcoal and handling ash. Regular cleaning is also important to reduce grease build-up and help limit flare-ups. Covering and storing it over winter helps prevent rust.
Where to Buy in the UK
Where to buy the CosmoGrill in the UK depends mainly on whether the buyer wants to see it in person first or prefers home delivery. In-store shoppers can check the build quality and the lid thermometer placement, then compare the footprint and folding features against the available barbecue space, including measuring the area beforehand. Online buyers often find it easier to compare current listings and returns, and they can verify the "3+1" burner layout and the dual fuel setup (gas plus charcoal). Availability can vary by retailer, so checking multiple approved UK sellers helps. Delivery charges and any collection options should also be confirmed with the selected retailer before purchase.
Frequently Asked Questions
Is the gas barbecue worth it?
For grilling on the go - camping trips, picnics and small patios, the CosmoGrill (a 3 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?
This gas barbecue is a 3 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 use?
The CosmoGrill Hybrid 4 Burner is a hybrid, running on both gas and charcoal. That gives you the convenience and instant control of gas midweek, plus the smoky flavour of charcoal when you have time. You'll need a gas bottle (usually patio gas or propane, sold separately) and charcoal. Hybrids cost more but suit anyone torn between the two.
Is the gas barbecue portable?
This gas barbecue is a portable / foldable model, designed to be moved and stored easily - good for camping, picnics, balconies and small patios. Check the packed size and weight, and remember you'll still need a gas canister. Portable BBQs trade cooking area for convenience.
What features does the CosmoGrill have?
The gas barbecue offers warming rack, lid thermometer. 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.
