Weber Genesis SP-435 4-Burner Gas Barbecue (Natural Gas)

If you want a premium Weber barbecue that feels effortless on a Tuesday night but powerful enough for a full backyard crowd on the weekend, the Weber Genesis SP-435 4-Burner Gas Barbecue (Natural Gas) is built for exactly that job. With a fixed natural gas connection, you get consistent fuel supply without bottle swaps — ideal for households that grill often and want “always ready” convenience.

The SP-435 sits in the upper end of the Genesis range, combining a stainless steel finish with performance features that make a real difference when you’re cooking across multiple zones: high-heat searing, controlled roasting, and space for sides — all at the same time.

Turn up the heat with the Weber Genesis SP-435 Sear Zone

The hero of this model is its ultra-hot Sear Zone, driven by Boost burners designed to push intense heat where it matters most. That means you can build a proper crust on steaks, burgers, lamb cutlets, prawns and skewers — while still keeping the rest of the grill at a more forgiving heat for finishing, holding, or cooking delicate food.

If you like steakhouse-style results, this is the feature that delivers them: fast heat, strong browning, and that satisfying “sizzle” you should expect from a premium Weber Genesis BBQ.

Even heat, better control, and that classic Weber flavour

A great barbecue isn’t only about maximum heat — it’s about even heat and repeatable results. The Genesis SP-435 is designed to spread heat across the cooking surface so you’re not stuck with hot spots and cold corners. Pair that with porcelain-enamelled cast-iron cooking grills and Weber’s flavourising system that vapourises drippings, and you get consistent cooking plus that signature barbecue flavour profile people chase.

This is the sort of setup that makes it easy to nail:

• crispy-skinned chicken without burning the outside

• sausages that brown evenly

• roasts that cook cleanly with the lid down

• vegetables that caramelise instead of steaming

Weber Crafted® versatility (with griddle included)

The Genesis SP-435 isn’t just a “grill-only” unit. It’s designed to become a flexible outdoor cooking station. The cooking grills are Weber Crafted® compatible, and this model includes a Weber Crafted® griddle, so you can go from open-flame grilling to flat-plate cooking whenever you want.

That opens the door to smashed burgers, breakfast cooks, fajitas, onions, stir-fry-style veg, toasted rolls, and all the food that’s simply better on a hot plate — without needing a separate appliance.

Side burner convenience: keep the whole meal outside

The side burner is one of those features you’ll use more than you expect. It’s perfect for sauces, corn, garlic butter, gravy, sautéed mushrooms, or keeping sides warm while the main event happens on the grill. It means less running back to the kitchen and more time staying with your guests (and your food).

Built for practical, everyday use

Premium barbecues should feel premium to use — not fussy to live with. The Genesis SP-435 is set up with the day-to-day details that make cooking smoother:

• an enclosed cabinet to keep tools and accessories tidy

• an expandable top cooking grill to free up space below

• integrated lighting to help when you’re cooking after dark

• easy-clean grease management for simpler maintenance

• lockable castors so it moves when you want, and stays put when you don’t

Natural gas BBQ note (important)

This model is Natural Gas only and is designed to run from a plumbed natural gas supply. It is not intended to run on LPG bottles. If you’re choosing between fuel types, this is the pick for homes that want a permanent gas point and the convenience of a steady supply.
