4+1 vs 6+1 gas BBQ

Updated: 23 October 2026

The titles say 4+1 and 6+1, and both carts show a side ring in the photo. 4+1 vs 6+1 gas BBQ is the decision with that ring held constant: four main burners under the hood, or six, for the same kind of wheeled LPG barbecue. It is not a lighting lesson and it is not a side-table explainer. Every kept listing is on the [gas BBQ with side burner comparison](/hub/grills-and-barbecues/gas-bbq-with-side-burner).

Reading 4+1 and 6+1

Four or six is the main-burner count. The +1 is a separate side gas ring. The ring is not a seventh steak zone, but it does count when you size a patio gas bottle. A 4+1 is not a three-burner appliance, and a 6+1 is not a five-burner appliance. If the listing only offers side tables, leave this choice until the ring is real. That split is on gas BBQ side burner vs side table.

People, zones, and grate size

Gardeners' World's 2026 rule of thumb puts at least four main burners against a household that regularly feeds six or more, and a 6+1 when you often load a full party at once. Four mains give a hot sear zone beside a cooler hold. Six mains add room for chicken, sausages, and a vegetarian corner at the same time. The side ring keeps sauces off the grate in both layouts. It does not replace a missing main when the grate is full. Grate language here is listing text. CosmoGrill Original prints 1,952 cm², model 93411 prints 2,602 cm², and the 6+1 cover listing prints 3,214 cm² with a 77 × 42 cm bullet. Use the listing you are buying. Do not average them.

Patio space and patio gas

A 6+1 is wider. In this set the CosmoGrill 6+1 body is about 149 × 55 × 110 cm with the hood closed, against roughly 126 × 50 × 103 cm on the Original 4+1 and 135 × 54 × 112 cm on model 93411. Weight fields on the 6+1 rows print 39 kg, so two people for assembly is realistic. Check the shed door and whether the side burner stops the cart sitting flush to a wall. Calor points a 5 kg Patio Gas bottle at up to three burners and a 13 kg bottle at four or more. Gardeners' World suggests at least 10 kg once you reach five or more burners. Count the side ring. Propane patio gas is typically 37 mbar with a 27 mm clip-on. None of the seven included lines names a hose. Quote one heat line: Campfire bullets say four 11.2 kW burners plus a 2.5 kW side burner while the field repeats 11.2 kW. CosmoGrill 6+1 prose can read as 12 kW on the mains plus 2.5 kW on the side, with a 14.5 kW material line and a 2,000 W field.

Four-main carts here are the two Campfire listings at about £169.99 (3.8 from 3 reviews on Pro+, 3.4 from 59 on Pro), the CosmoGrill Original at about £199.99 (4.4 from 1,036), and model 93411 at about £269.99 (4.3 from 910). Six-main carts are model 93416 at about £289.99 without a cover in the title (4.4 from 269) and the same model at about £299.99 with a 600D cover in the title (4.5 from 366). For most households, four mains are enough. Start with the Original for review depth, or 93411 if locking castors matter more than saving about £70. Move to a 6+1 for a regular party load, with space and two builders. The cover twin is weatherproofing, not a different burner count. The BROILUCK 2+1 at about £89.99 is a small-budget footnote, not a third contestant. Lighting sits on how to light a gas BBQ side burner.

Common questions

What does 4+1 mean versus 6+1?
Four or six main burners under the hood, plus one side gas ring. The plus-one is not a shelf and not an extra main burner for steak zones.
Is four main burners enough for a family of four?
Usually yes for everyday cooks, and Gardeners' World's small-cart rule even points smaller burner counts at four people. Choose four mains especially when you sometimes feed six. Jump to six mains when a full party load is normal.
When do I need six main burners?
When you regularly cook for a large group at once and need more simultaneous zones than four mains give you. In this set that is the CosmoGrill 6+1 pair around £290 to £300.
Does the side burner count as a main burner for bottle size?
For bottle rules of thumb, count it. Calor and Gardeners' World guidance sizes bottles by how many burners the appliance can run, not by ignoring the ring.
How much wider is a typical 6+1 cart?
In this set the CosmoGrill 6+1 body is about 149 cm on the long side against about 126 to 135 cm on the CosmoGrill 4+1 rows. Always check the listing you buy and your patio clearances.
CosmoGrill Original 4+1 or jump straight to a 6+1?
Stay on the Original at about £199.99 if four mains cover your weekends and you want the deepest review file. Jump to a 6+1 only when party loads are regular and the wider footprint fits.
Where does the 2+1 fit in this choice?
As a small-budget footnote with two mains, not as an equal third option in a 4+1 versus 6+1 decision.
Do the two 6+1 listings differ only by the cover in the title?
They share model number 93416. The about £299.99 listing names a 600D cover in the title and first bullet. The about £289.99 listing does not. Burner layout stays 6+1 on both.
