Smart Energy GB is the voice of the smart meter rollout. ItÍs our task to help everyone in Great Britain understand smart meters, the national rollout and how to use their new meters to get gas and electricity under control. Smart meters replace the traditional meters we currently have in our homes. They provide accurate bills, near real time information on energy use in pounds and pence, and greater control over gas and electricity. The smart meter rollout is an essential technology upgrade, unprecedented in its scale, to improve Great BritainÍs energy infrastructure. More than three million smart meters have already been installed, and between now and 2020 every household in England, Scotland and Wales will be offered one at no additional cost.
