Unlike other sites, we test every induction hob we review thoroughly over an extended period of time. We use standard tests to compare features properly. We’ll always tell you what we find. We never, ever, accept money to review a product. We test how long it takes to bring pans of water from 20C to 90C: we measure times for 1.5-litres of water in a large pan, 1-litre in a medium pan and 500ml in a small pan. We use the most appropriate sized burner for each hob. We also test how long the large pan takes to heat up, while all other burners are in use. This helps us see if there are any power-sharing options going on, where only one burner can be run on maximum power. We test a hob's usability features: any auto-cooking features, such as chocolate melting; how timers work; and any smart features. By cooking on each hob, we can also tell you what each model is like to use, and how easy they are to clean.
