From the BBC story...
A spokesperson for the department for business, energy and industrial strategy, said: "Smart meters are a vital upgrade to Britain's energy system."
"The technology will bring an end to estimated billing, and give consumers real-time information about their energy use to enable them to make more efficient energy choices."
