Induction hobs are not just a fashionable addition to a new kitchen, but are also sold as a more efficient choice than a gas hob. How do they compare? Is cooking on an electric induction hob better for the planet? And what about our health?

Listener Roisin wants to know if they are an economical choice but worries they might affect her mum's pacemaker, while listener Anna is concerned about indoor air pollution from gas cookers and wonders if induction hobs are a safer bet.

Greg Foot gets them some answers with expert help from Emily Seymour, the Energy Editor at Which? and Jonathan Grigg, Professor of Paediatric Respiratory and Environmental Medicine at Queen Mary University of London.
