Shopping for a gas BBQ in the UK is a classic trade-off: instant, controllable heat versus size, build quality and year-round weather resistance. Do you choose a compact 3+1 burner that’s easy to live with for family dinners, or step up to a 4+1 or huge 6+1 for parties and batch cooking? Add in UK gas bottles, regulators, and covers, and the right choice comes down to how you cook, not just how many burners you get.

01
Family-Sized Gas Power With Side Burner Versatility and Easy-Roll Storage
Positioned as the leading option in this gas barbecue set, this Outsunny trolley model earns its place through practical capacity rather than gimmicks. Market research shows its metal and stainless steel frame with powder-coated finish feels sturdy and smart on the patio, while the large main grill plus warming rack comfortably handles family batches and entertaining. Owners consistently praise fast heat-up, even cooking on low to medium settings, and the removable drip tray that simplifies cleanup. Ergonomics are thoughtful, with dual side shelves, an enclosed cabinet for tools, lid thermometer for closed-lid control, and two wheels for repositioning. The extra side burner adds useful versatility for sauces and sides while helping avoid cross-contamination. Balanced against that, assembly regularly takes around two hours with two people and instructions can feel vague, and side burner alignment occasionally needs patience. Overall verified sentiment remains strongly positive for durability, ease of use and everyday value.
- Spacious multi-zone cooking surface ideal for family batches and entertaining
- Heats quickly and cooks efficiently even on lower settings
- Removable drip tray and powder-coated finish simplify cleaning
- Handy storage with side shelves, cabinet and smooth-rolling wheels
- Assembly typically needs two people and instructions can feel vague
- Side burner alignment can be fiddly and heat runs hot, requiring careful control
02
Family-Size 4+1 Burner Power That Makes Everyday Outdoor Cooking Effortless
Positioned as an entry point into full-size gas grilling, this 4+1 configuration stands out for sheer versatility based on extensive owner feedback. The four individually adjustable stainless burners with flame tamers deliver even heat across a wide enamelled cooking surface, while the side burner handles sauces, vegetables and sides without leaving the grill. A full-length warming rack and lid-mounted temperature gauge add useful control for larger groups. Practical touches like the removable grease tray, dishwasher-friendly grates, enclosed bottom cabinet and smooth-rolling castors simplify everyday use and patio storage. Build quality is widely described as sturdy and smart-looking for the tier, though the lighter-gauge steel is not on par with high-end stainless models and benefits from a cover in harsh weather. Assembly consistently takes one to three hours and is best treated as a two-person job with clear space and basic tools. Overall sentiment points to reliable heating, easy cleanup and strong family value.
- Generous cooking area comfortably handles larger family gatherings
- Individual piezo ignition and adjustable burners offer flexible heat control
- Side burner, warming rack and storage cabinet boost real-world versatility
- Removable grease tray and enamelled grates make cleanup straightforward
- Assembly is fiddly and time-consuming, ideally requiring two people and good tools
- Gas hose and regulator not included, plus lighter-gauge steel needs a cover for long-term outdoor protection
03
Huge 6+1 burner power built to feed the whole garden party
Positioned as a high-capacity family and party grill, the Pro Deluxe 6+1 pairs a powder-coated steel cart and aluminium frame with stainless steel burners and enamelled grates. Its double-walled hood with built-in thermometer aims to hold steady heat, while V-shaped flame tamers help limit flare-ups and protect burners from dripping fat. In everyday use, verified owners praise its sheer scale, with a wide 77x42cm main surface plus full-length warming rack that comfortably handles large family cookouts and even 50-plus guest events. Individual piezo ignition in each knob, continuously adjustable burners, side burner for sauces, removable grease tray and enclosed storage add genuine practicality. Assembly is generally straightforward though time-consuming, with the side burner connection noted as fiddly. Long-term feedback is mostly positive on sturdiness and cooking evenness, tempered by reports of paint wear, light rust on doors and enamel flaking if stored outdoors permanently. A regulator and hose must be sourced separately.
- Massive cooking surface easily handles large gatherings and batch cooking
- Individual piezo ignition and precise per-burner control for flexible heat zones
- Even, powerful heat with fast preheat and well-controlled flare-ups
- Thoughtful extras including warming rack, side burner, storage cabinet and fitted cover
- Regulator and hose not included and must be sourced separately
- Assembly is lengthy with fiddly side-burner pipework
- Paint finish and cabinet doors can show wear or light rust with permanent outdoor storage
04
Seven-burner entertaining powerhouse built to easily feed up to 18 guests.
Positioned as a maximum-capacity option in the gas barbecue category, this CosmoGrill leans into sheer cooking space and versatility. Market research shows its six stainless burners with V-shaped flame tamers deliver even, high-heat performance topping 300C, while the separate side burner adds genuine meal flexibility for vegetables, sauces and appetisers. Owners consistently praise the sturdy feel once assembled, easy-clean enamelled grates and removable grease tray, plus thoughtful extras like the full-length warming rack, enclosed storage cabinet and smooth-rolling castors. Ergonomics are party-friendly, with side table prep space and a heat-resistant handle. The trade-off is setup: verified sentiment flags a lengthy two-person assembly with dense instructions and many small parts. The matt black finish can also highlight grease marks, and a regulator and hose must be sourced separately. For large families and hosts who regularly cook for a crowd, however, satisfaction remains high. Overall it suits confident assemblers seeking volume over compact convenience.

Buyer Questions and Expert Answers
What is the best overall gas BBQ for most UK homes?
The Outsunny 3+1 Burner Gas BBQ Grill is the best all-rounder for most families. Its 3+1 system with warming rack gives generous multi-zone space for burgers, chicken and vegetables at once, it heats quickly and cooks well even on lower settings, and the enclosed trolley with wheels plus removable drip tray makes daily use and cleaning simple.
How many burners do I really need: 3+1 vs 4+1 vs 6+1?
Think in portions, not just burners. A 3+1 comfortably handles 4-6 people with room to keep food warm. A 4+1 like the CosmoGrill Original adds width for larger family gatherings and more flexible zones. A 6+1 like the Pro Deluxe is for regular entertaining of 10+ or batch cooking, but needs more patio space, more gas and longer assembly.
What gas bottle, regulator and hose do I need in the UK?
Most full-size gas BBQs run on propane or patio gas with a specific regulator (commonly 27mm clip-on for patio gas or screw-on for propane). Two of our winners require you to source hose and regulator separately, so check the inlet type, buy a certified hose with correct clips, and ensure your bottle fits inside or beside the cabinet. Always leak-test connections before first ignition.
Are gas BBQs difficult to assemble?
Expect 60-120 minutes and ideally two people. Panels, lids and side-burner alignment are the fiddly parts, and instructions can feel vague. Use your own screwdrivers and spanners, lay out all parts first, do not fully tighten until aligned, and place the BBQ on a flat, non-flammable surface with clearance from fences and walls.
How do I clean and protect a gas BBQ for winter?
After each cook, burn off residue on high for 10 minutes, brush grates, then empty and wash the drip tray. Periodically check burner ports for blockages and wipe the powder-coated body. For year-round outdoor storage, use a breathable weatherproof cover, disconnect and store the gas bottle upright outdoors, and keep the BBQ sheltered from standing water.
The Bottom Line
- 🏆 Top Overall Choice: Outsunny 3+1 Burner Gas BBQ Grill with Wheels 110L x 50W x 100Hcm Black — best balance of family capacity, quick heat and easy cleaning
- 💰 Best Value: CosmoGrill Original 5 Gas Burner 4+1 Garden Grill — most versatile cooking space with side burner and cabinet for larger gatherings
- ⭐ Premium Pick: CosmoGrill Pro Deluxe 6+1 Gas BBQ with Weatherproof Cover, Black — maximum 6+1 capacity with precise zone control and cover included
For most UK buyers, balance beats sheer size: easy lighting, controllable zones and simple cleaning will get used far more than extra burners. Pick the compact, well-organised 3+1 if you want hassle-free family grilling, step up to the 4+1 if you host larger groups and want full-meal versatility, and choose the 6+1 only if maximum capacity and included weather protection justify the bigger footprint and longer build. Whichever you choose, sort your regulator, bottle and cover upfront for safe, year-round grilling.
