Style and Setting
Style and Setting suits people who want a gas BBQ that can be moved to suit where cooking is needed, rather than staying fixed in one backyard spot. This gas barbecue is built for outdoor use, with a portable, foldable trolley designed to help it move between patios, driveways and garden areas. The foldable trolley packs away more neatly after meals, though frequent folding may take a little practice to keep the parts aligned. The stainless steel build is designed for outdoor exposure, and a lid thermometer adds practical control during cooking.
Size and Seating
Size and seating on the Onlyfire are based around a 22-inch cooking grate, which makes it more suitable for small to medium outdoor gatherings than for very large groups. The 3-burner layout allows several items to be cooked at once, but the overall grill surface still remains limited. When planning meals, grouping foods by thickness and cooking time helps reduce the impact of overcrowding, which can slow heating. The portable, foldable trolley-style design supports placing the BBQ in a patio corner or garden area, but it does not add extra dining or seating space.
Materials and Build
Materials and build on the gas barbecue focus on basic outdoor durability, with stainless steel listed for use, plus a lid thermometer for temperature checking during cooking. The grill's framework and fasteners are intended to handle folding and moving, since poor alignment can loosen over time with transport. Stainless steel use helps resist rust in wet weather, although coating damage can still shorten lifespan. The included thermometer supports steadier results by reducing guesswork when food needs a set heat range. Overall construction suits everyday UK garden use, while heavy impacts remain a risk.
Comfort and Features
The Onlyfire is built for practical outdoor cooking. It includes a lid thermometer to help users monitor cooking temperature without repeatedly opening the lid, which can affect cooking time. The BBQ has a 22-inch cooking grate that provides a workable area for everyday meals. A side table shelf supports food prep while grilling, and the foldable trolley design is intended to make it easier to move between patios or to store away. Comfort and usability depend on available space, as the trolley and side shelf require room to fold and unfold safely. Overall, the features are geared towards convenience rather than advanced controls.
Who Is This For?
This portable gas BBQ suits people who want an outdoor grilling setup that can be moved and set up with less hassle than a fixed, built-in cooker. It fits best for households that grill occasionally, such as weekend cooks, because the foldable trolley and side shelf help with storage and basic prep. It also works well for small patios and balconies, since a 22-inch cooking grate supports typical portions for a few diners. Those planning heavy-duty, very large batch cooking may find the portable footprint limiting. Buyers who value clear temperature monitoring can keep an eye on heat more consistently using the thermometer reading.
Where to Buy in the UK
Finding the right place to buy the gas barbecue in the UK helps shoppers match the grill's portable, foldable setup with their space and delivery needs, as it is designed for outdoor cooking rather than fixed installations. Buyers commonly check major UK retailers' online listings, plus marketplace sellers that can deliver to their postcode. Because the grill includes a 22-inch cooking grate, product pages should clearly state dimensions and delivery terms. Some listings may show dispatch and delivery details only at checkout, while others publish delivery windows up front. Shoppers should confirm that the listing matches the 3-burner configuration, 7kW rating, thermometer, side shelf and foldable trolley, along with the stated grate size.
Frequently Asked Questions
Is the Onlyfire 3-Burner Portable Gas worth it?
For grilling on the go - camping trips, picnics and small patios, the Onlyfire (a 3-burner gas BBQ) does the job with 7kW of heat. 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 Onlyfire is a 3-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.
How powerful is the gas barbecue?
This gas barbecue puts out 7kW. Higher output means faster preheating and better searing, though total power matters less than how evenly it's spread across the cooking area. Look at power alongside the burner count and grill size rather than on its own - a well-designed BBQ with good heat distribution beats a higher figure with hot and cold spots.
What fuel does the Onlyfire use?
The Onlyfire 3-Burner Portable Gas 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 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 Onlyfire have?
The gas barbecue offers lid thermometer. 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 Onlyfire?
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.
