Question

To ask the Secretary of State for Energy and Climate Change, how many In Home Displays have been installed in households to date; and how many such displays are still in operation 12 months after installation.

It is not possible to give an accurate figure on the number of In Home Displays (IHDs) installed as while energy suppliers are required to offer their domestic consumers an IHD where they install a smart metering system, domestic consumers can choose not to accept one.

Data from the Early Learning Project1 (ELP) which covered the very early part of the rollout at time when energy suppliers were trialling and testing approaches to consumer engagement, found that six in ten (61%) smart meter customers who had received an In Home Display (IHD) reported that they still had their IHD plugged in. These consumers had had their smart meters over a period of between six months and two and half years. The research also found that smart meter customers who had received their installation more recently were no more likely than those who did so around two years ago to still have their IHD plugged in.
