Most people replace their kettle with whatever's cheapest when the old one breaks. But the difference between a £15 model and a thoughtfully designed £25 option is noticeable — in boil speed, noise, ease of pouring, and lifespan. The three specs that matter most: wattage (3kW is fast), capacity (1.7L serves a family), and whether it has a keep-warm function if you make multiple rounds.
💰 Best Under £20 — Russell Hobbs Electric Kettle
A 4.7-star rating from over 500 buyers for a £15 kettle is genuinely impressive. This Russell Hobbs covers all the basics — 1.7L capacity, rapid boil, 360° cordless base — without any frills. If you just need a reliable, fast kettle at the lowest possible price, this is the one.

🫖 Kettle buying guide
Here's what actually makes a difference in day-to-day use:
- Wattage: 3kW boils 1.7L in under 3 minutes. Cheaper kettles may be 2–2.5kW — noticeably slower.
- Capacity: 1.7L is the UK standard. If you mainly make 1–2 cups, a smaller 1L travel kettle saves energy.
- Variable temperature: Green tea brews best at 80°C, white tea at 70°C. Budget kettles don't have this — if you're a serious tea drinker, it matters.
- Keep warm: Holds temperature for 20–30 minutes. Useful when making multiple rounds. Usually only on mid-range and above.
- Noise: Some kettles rattle loudly. If you have an open-plan kitchen or light sleepers nearby, check reviews specifically for noise comments.
