Smart-meters have the potential to bring great benefits to consumers, suppliers and the UK energy infrastructure. Smart meters allow energy suppliers to get remote electricity and gas readings of households and businesses using mobile phone-type signals and wireless technologies. The roll-out of smart meters in the UK is due to take place between 2015 and 2020 with an estimated 53 million devices to be installed by energy suppliers in 28 million homes and 2 million businesses. The Department of Energy and Climate Change (DECC) estimates that the roll-out of smart meters cost around £12.1 billion and these costs will be passed onto consumers. However, smart meters are expected to achieve approximate savings of £18.8 billion. The roll-out of smart meters must be managed carefully if these benefits are to be achieved and costs are to be kept under control. The Committee first investigated UK Smart Meters in 2013 and is now investigating the Government’s progress on this ambitious project.
