Compare current retailer offers alongside a detailed BestBuysUK product review and Score.
🏆 Review & price summary
The Siemens KS36NAXCG iQ500 larder fridge offers 402 litres of dedicated chilled storage, C-rated energy efficiency, quiet 35dB operation and a useful connected feature set. HyperFresh, Total noFrost, superCooling, multiAirflow and flexible door storage make it well equipped for organised fresh-food storage. It is best suited to households that already have a separate freezer and enough space for its 663mm depth.
✓ Key strengths
- ✓ 402 litres of dedicated chilled storage in a standard 595mm-wide footprint
- ✓ C energy rating with stated annual consumption of 110kWh
- ✓ Quiet 35dB operation with B-rated airborne noise emissions
- ✓ HyperFresh, Total noFrost, superCooling and multiAirflow cooling
- ✓ Home Connect app control with remote monitoring and control
- ✓ Reversible door, Flex shelf, five door bins and LED soft-start lighting
Worth considering
- There is no freezer compartment, so frozen-food storage requires a separate appliance
- The 663mm overall depth is greater than the nominal 600mm installation depth and needs careful kitchen clearance planning
- Only one of the four fridge shelves is adjustable, giving less shelf-height flexibility than some rivals
- There is no water or ice dispenser, so chilled water cannot be accessed without opening the door

Large, well-organised storage
The Siemens KS36NAXCG fridge provides 402 litres of total chill capacity in a tall 1,862mm-high cabinet that is 595mm wide. Its four internal shelves, five door bins, bottle support and Flex shelf give useful everyday storage flexibility, although only one shelf is adjustable.
This is a larder fridge rather than a fridge freezer, so all of the available space is dedicated to fresh and chilled food. That makes it particularly suitable for larger households that already have a separate freezer.
Strong cooling and freshness features
The Siemens KS36NAXCG fridge combines hyperFresh storage, Total noFrost, superCooling and a metal backwall with multiAirflow. These features are designed to maintain more even temperatures, reduce frost build-up and help manage fresh food efficiently.
A reversible door, open-door warning and flexible door storage add practical convenience. The LED soft-start lighting and seven-segment display are useful finishing touches for everyday use.
Smart controls and connected operation
Home Connect provides app-based connectivity, including remote monitoring and control and iService remote functions. The appliance can also be operated through its physical buttons, so connected features are an addition rather than the only control method.
The connected functionality is a notable advantage for shoppers who want to check or adjust the fridge remotely, although it requires the appliance to be connected to the relevant Home Connect account and network.
Efficiency, noise and installation
The C energy rating and stated annual consumption of 110kWh give the Siemens KS36NAXCG fridge a strong efficiency profile for its large capacity. Its 35dB noise emission and B noise-emission class also make it a quiet choice for open-plan kitchens.
The 663mm depth is greater than the nominal 600mm installation depth, so surrounding clearances and door opening space need to be checked carefully. At 68.2kg and 1,862mm tall, it also needs sensible access planning during delivery and installation.
Overall assessment
The Siemens KS36NAXCG fridge is a feature-rich tall larder model with particularly strong capacity, freshness technology, connectivity and noise performance. Its main trade-offs are the lack of any freezer compartment, the deeper cabinet and limited shelf-height adjustment.
For buyers seeking a connected, high-capacity freestanding fridge rather than an all-in-one fridge freezer, it is a well-rounded option with a useful combination of practical storage and modern controls.
