The low take-up of smart meters is one of the big challenges that faces the energy market. It is very much linked to some of the problems that customers have around the country. I mentioned in my statement that just having a smart meter cuts Bills by 3%, before even investigating the access it gives to a range of tariffs. Anything that can be done to improve the roll-out must make a difference. We also heard evidence from Martin Lewis about the importance of this matter. Giving people more access to tariffs is part of what the Government want to do, and it is consistent with the evidence that we heard. How we increase the smart meter roll-out will be key; clearly, it has not gone well so far.
