CosmoGrill Pro Deluxe 4+1
Our verdict · The most cooking space per pound — a big-capacity family grill for well under £300, if you accept a shorter life.
Buy it if
Budget and sheer cooking space win — big or occasional gatherings on a tight outlay, where a shorter warranty is an acceptable trade-off.
Skip it if
You prioritise long-term durability, premium heat control or a long warranty, or if your patio is small — this is a large, value-first buy.

The Pro Deluxe 4+1 is the value and big-capacity pick. Four main burners plus a side burner deliver 10 kW main and 2.5 kW side (12.5 kW total), and CosmoGrill says it caters for up to around 15 people — the largest capacity in this shortlist for less than half the Rogue's price. You also get a side burner as standard (which the base Weber and Napoleon omit), a steel warming rack, a built-in temperature gauge, a wheeled trolley with storage, and compatibility with add-on cast-iron grate and reversible griddle accessories. CosmoGrill is a well-known maximum-features-for-the-money budget brand in the UK. It ranks fifth because the trade-off is real: just a 1-year manufacturer warranty against the staged multi-year cover of the premium picks, plus a large footprint. Price is indicative; cylinder and regulator cost extra.
The good & the bad
Pros

Cons
- Just a 1-year manufacturer warranty — the shortest cover here
- Large footprint and value-grade heat control, not a long-term investment
