Dragons' Den star Deborah Meaden and BBC 5 Live’s Felicity Hannah are on a mission to find out how your money matters in the fight against climate change. As energy bills go up again, this week’s episode is all about how we heat and power our homes. Deborah and Fliss talk to Chris O’Shea, boss of British Gas’ parent company Centrica. He believes hydrogen and heat pumps will be warming our homes in the near future and says we should re-open the debate about fracking.

Plus an extended question and answer session on everything from how those of us in rented houses can make our homes more energy efficient, to the important question of “what actually is a heat pump?”
