How to choose a kettle

Most kettles boil water. The differences that matter are small, and you can ignore most of the marketing.

What matters

Feature	Worth paying for?	Why
3kW power	Yes	Boils a full kettle in under three minutes
Removable filter	Yes	Keeps limescale out of your tea
Variable temperature	Only if you drink green tea or use a cafetiere	Adds £10 to £20
Glass body	Looks good	Shows limescale sooner

Our pick

For most kitchens the Aura 1.7L does everything above for under £25. If you live alone, the 1.0L compact heats less water, so it boils faster and wastes less.
