Samsung Series 5 RB38C605DB1

The Samsung Series 5 RB38C605DB1 is the pick for households that simply need more room. At 390L (276L fridge / 114L freezer) it has the largest total capacity and biggest freezer here, and Samsung's SpaceMax technology uses thinner walls to fit that volume into a standard 60cm-wide cabinet. It is Total No Frost, rated at a low 35 dBA and energy class D at roughly 211 kWh/yr — better running costs than the F-rated Hisense and Beko, if not the Liebherr. Wi-Fi and SmartThings let you monitor and adjust it from a phone, and a 10-year warranty covers the compressor. It ranks below the Liebherr because, while it's cheaper and far bigger, it is less efficient (D vs B), slightly noisier (35 vs 34 dB) and its long warranty covers only the compressor rather than the whole appliance. Against the Bosch, you gain capacity, quietness, efficiency and smart features but pay noticeably more. Indicative pricing starts around £679; like the Bosch it stands 203cm tall.
