Only 23% of people are aware of smart meters and understand them.

Claire Maugham, Director of Policy and Communications at Smart Energy GB, told ELN those householders are “loving” the technology.

Smart Energy GB is the national campaign for the smart meter rollout.

She added: “We speak to consumers twice a year as part of the largest independent survey of energy and smart meters and what we find is that eight in 10 people who’ve already got smart meters would recommend them to others.

“Around half of them say that they are saving money and most importantly they are feeling more confident about what they are using, they are feeling happier that they are on the right tariff and with the right supplier.”

Although more than two million smart meters have been installed so far across the country, Ms Maugham explained some concerns people still have about smart meters.

She added: “In general there’s very low levels of concern about smart meters. People do have some sensible comments and questions about how secure their data is and about how the service they are getting from energy suppliers could change in the future. People have questions about the new types of tariffs that there will be in the future and I think people also want to know exactly what the benefits are and what those benefits will be as we move towards – go live of the DCC [Data and Communications Company].”
