Sage the Smart Kettle vs the Soft Top Luxe Kettle — Comparison

Sage the Smart Kettle costs £99, while Sage the Soft Top Luxe Kettle costs £119. Both sit in Sage’s premium kettle line-up rather than its most basic boiling-only tier, but they emphasise different comforts. The Smart Kettle is the lower-priced model with a keep-warm function, while the Soft Top Luxe is the dearer option aimed at a more refined filling and pouring experience for buyers who notice everyday handling details.

Both models are cordless, use a 360 degree base and have 2400W wattage, so there is no power gap in the supplied data. The Smart Kettle’s standout feature is keep warm, which helps when you make several drinks close together. The Soft Top Luxe instead lists a water level indicator, giving clearer control when filling and helping avoid boiling more water than you need during smaller tea rounds, saving time and reducing unnecessary reboils.

The Smart Kettle suits tea and coffee drinkers who reboil often and would rather keep water warm between cups than pay extra for a more comfort-led body. The Soft Top Luxe suits buyers who like Sage’s Luxe styling and want visible water-level guidance for everyday use. The £20 premium does not add stated wattage or listed capacity, so it is best justified by handling, finish and filling convenience in a kitchen where the kettle stays on display.

Bottom line: choose the Smart Kettle if you want a £99 Sage model with 2400W power, cordless use, a 360 degree base and keep-warm function for repeat drinks and busy mornings at home daily / opt for the Soft Top Luxe if you prefer a £119 Sage kettle with the same wattage plus a water level indicator and Luxe usability.
