Siemens iQ700 71l Capacity Smart Built-In Oven - Black vs iQ700 67l Capacity Smart Built-In Microwave Oven — Comparison

HB776G1B1B is the Siemens HB776G1B1B iQ700 71L Capacity Smart Built-In Oven in black, priced at £1,099, while HM776G1B1B is the Siemens HM776G1B1B iQ700 67L Capacity Smart Built-In Microwave Oven at £1,699. Both are premium iQ700 smart built-in ovens, but the HB776G1B1B is the larger standard oven choice, while the HM776G1B1B adds microwave functionality and advanced cleaning features at a much higher price.

The HB776G1B1B offers a 71L net capacity, full-width grill, smart built-in oven features, double-glazed door and an A+ energy rating. The HM776G1B1B has a slightly smaller 67L capacity, smart controls, microwave function, activeClean and humidClean Plus. The HB776G1B1B gives 4L more oven space and a stated energy rating; the HM776G1B1B gives combination microwave cooking plus two maintenance features. Both are smart, but the HM model is more versatile for speed, while the HB model is better for pure oven capacity.

The HB776G1B1B suits buyers who want a high-end Siemens oven for roasting, baking and grilling but do not need microwave integration. At £1,099, it is significantly better value for a full-size smart oven. The HM776G1B1B suits busy households, design-led kitchens and users replacing both an oven and a microwave with one built-in appliance. Its activeClean and humidClean Plus features help justify the premium, but the £600 gap is substantial if microwave cooking is only occasional.

Bottom line: "choose HB776G1B1B if you want the larger 71L iQ700 smart oven at the stronger £1,099 price / opt for HM776G1B1B if microwave cooking, activeClean and humidClean Plus are worth paying £1,699."
