Recommendation 3

The Department has limited understanding of why smart meter coverage is lower in some areas—particularly London, rural and remote areas—compared to others. The extent of smart meter installation varies across Great Britain, from 5% in the Isles of Scilly to 69% in Chesterfield as at March 2023. Installation rates in London are 43%, some way below the 57% being achieved across Great Britain. The Department thinks this is due to the challenges of installations in blocks of flats (where it is more difficult to place meters and in-home displays in sufficient proximity to each other), and also because installers cost more and are less available. Remote areas such as the Highlands and Islands of Scotland also have lower coverage, as do some rural areas such as the Cotswolds. The Department says that the Data and Communications Company, which operates the central communications and data platform for smart meters, is looking into options for the 0.75% of homes that sit outside its ‘wide area network’ coverage (known as “not-spots”) for smart metering. The Department referred to the ‘few hundred thousand’ homes in these areas as located in ‘not-spots’. However, we also note that some suburban areas such as the constituency of Richmond Park can have low coverage but have neither the characteristics of inner London nor rural or remote areas. Recommendation 3: The Department should set out in its Treasury Minute response how it will: a) increase its understanding of the reasons for variation in geographic coverage, and what it is doing to increase smart meter uptake in those areas that are lagging behind; b) set out how those households who are unable to install smart meters will be supported.
