Our top picks for smart kettles in 2026
Tested for boil accuracy, app reliability and UK kitchen practicality:
Best overall: Smarter iKettle 4th Gen — best app, keep-warm, voice control
Best for coffee: Fellow Stagg EKG Pro Smart — barista-grade temperature, beautiful design
Best value: COSORI Smart Gooseneck — pour-over coffee control at under £60
Smart kettles sit at an odd intersection: the one kitchen appliance every UK household boils multiple times a day, combined with app control that you may or may not actually need. After 10 weeks of real usage, we have a strong view on who should spend £90 on a Smarter or Fellow Stagg kettle versus sticking with a £25 Breville.
Short answer: smart kettles are worth it if you drink speciality coffee (temperature control is essential), if you have young children (sleep-schedule boil is a real QOL improvement), or if your home is heavily smart-home automated. Otherwise, a manual kettle wins on practicality.
1. Smarter iKettle 4th Gen — The UK’s original smart kettle, now genuinely useful
Our score: 4.5/5
The 4th generation iKettle is the first Smarter kettle we would fully recommend. WiFi boils via app or voice, keep-warm up to 30 minutes, 1.8L capacity, 3kW UK mains speed. Works with Alexa, Google Home and IFTTT. We used it as part of our morning routine: alarm triggers kettle boil at 6:55am, done by the time we are in the kitchen.
Pros
- Alexa and Google Home voice control works reliably
- App-scheduled boils integrate with alarm apps
- 1.8L capacity suits family use
- Keep-warm holds temperature for 30 minutes
- Removable base for manual pouring if needed
Cons
- Smarter app quality lags Hue/Tapo polish
- Premium pricing at £99-£129
- No temperature control below 100°C (boil-only)
- Plastic-heavy construction

The app (Fellow Drops) has guided recipes for V60, Kalita and Aeropress brewing.
Pros

Temperature control matters for hot drinks beyond black tea
If you only drink English Breakfast, a manual kettle is fine. Green tea (75°C), pour-over coffee (92-96°C), matcha (80°C), and baby bottles (70°C) all benefit from precise temperature control.
Scheduled boils save about 10 minutes a day
The real win from a smart kettle is the ability to schedule a morning boil or trigger it from bed via voice. That plus keep-warm can genuinely save the time spent watching a kettle boil every morning.
UK 3kW speed vs EU standard
UK kettles run at 3kW from a 13A plug and boil 1L of water in about 2-3 minutes. EU and US kettles are often slower. Check the wattage of any imported smart kettle before buying — some US models boil half as fast.
Voice integration is the real feature
Alexa or Google voice control is the smart-home feature most people actually use daily. If your hands are full (cooking, nappy change, working), ‘Alexa, boil the kettle’ genuinely earns its keep.
Frequently asked questions
Are smart kettles worth it for UK households?
For most households, only marginally. Unless you have specific use cases — serious coffee, green tea, baby bottles, or heavy smart-home use — a good £25 Breville does 95% of what a £100 smart kettle offers.
Do smart kettles use more electricity than normal ones?
The boiling process is the same energy (it takes 336 kJ to heat 1L from 20°C to 100°C, regardless of kettle). Keep-warm adds about 50-80W continuous draw, which can add £0.50-£1 per week if used heavily.
Can I use a smart kettle as a normal kettle?
Yes. All the smart kettles we tested work as regular kettles via physical buttons or a power toggle. The ‘smart’ is additive, not required.
Do I need WiFi at my kettle’s location?
Yes, for the app and voice features. Most UK kitchens have adequate WiFi, but thick granite worktops or rear-of-house kitchens may need a mesh extender.
Is temperature control really worth the price?
For pour-over coffee or delicate teas, yes — the difference between 95°C and 100°C water is significant for extraction. For English breakfast tea, full boil is fine and temperature control is overkill.
How long should a smart kettle last?
Expect 3-5 years with normal UK usage (5-8 boils per day). Limescale is the main killer; descale monthly in hard-water areas. Electronics sometimes fail before the heating element.
