Public and business electricity consumers might notice a benefit from the roll out of smart meters.
Energy and climate change minister Charles Hendry said: "I am determined that consumers are at the heart of this ambitious programme."
The devices will be provided to 30 million households and small enterprises by 2019.
Users will have control over who has access to their data, apart from "where it is required for billing or other regulated purposes", the parliamentarian stated.
Westminster confirmed there are to be no sales when the meters are being installed and that energy efficiency advice must be provided during the visit.
Furthermore, all recipients will be offered a display system, allowing them to monitor how much power they are using and helping them to work out how much it costs.
British Gas has begun providing members of the public with an advanced smart meter, enabling them to compare their energy consumption by the hour and assisting them in reducing their bills.
