Smart Energy GB undertake regular research into smart meters and how they are used. The outcomes are published on their website.
Research published in May 2019 here found that smart meter owners are more engaged with energy compared to non-owners. They are more likely to understand their own energy use and have a desire to reduce it. Households with a smart meter are doing slightly more to save energy than those without. In particular, smart meter owners are more likely to look into ways to use less energy. Over time, smart meter owners continue to encourage others to use less energy, and increasingly look into energy efficiencies.
