Conclusions (20)

Observations and findings
2 Conclusion Accepted
We are concerned that smart meters are not achieving the consumer benefits they are supposed to and are benefitting certain, often wealthier, consumers more than others. The Department’s most recent estimates of consumer energy savings are based on data from installations that took place between 2015 and 2018 (with consumption …
Government Response Summary
The government agrees and has published an independent evaluation in Summer 2023, which identified energy savings. They are also designing a new phase of program-wide evaluation and working on additional sources of evidence to supplement the existing data.

4 Conclusion Accepted
Ofgem risks neglecting the importance of consumer engagement and behaviour change by focusing on penalising suppliers for missing targets. Energy suppliers have binding targets to install smart meters, which should be enforced by Ofgem, the energy regulator. However, energy consumers are not required to accept an offer of having smart …
Government Response Summary
The government agrees, stating that Ofgem already considers consumer detriment, priority, and Net Zero obligations in its enforcement processes. They also expect energy suppliers to engage customers effectively and that this is factored into Ofgem's consideration of supplier performance against targets.
View Details →
6 Conclusion Accepted
The smart meters programme has been going for more than a decade and it is not clear how the Department takes important decisions relating to its future, including how it will decide when to bring the Programme to a close. The government first announced its intention to mandate suppliers to …
Government Response Summary
The government agrees and commits to sharing cost and benefit information for the smart metering rollout with Parliament annually. They have also defined the criteria for program closure and will share transition plans once matured.

17 Conclusion Acknowledged
As at March 2023, 3 million smart meters were not working properly; which means that these meters were either not sending energy use information to suppliers or not displaying this information to consumers, or both. This equated to 9% of the 32.4 million smart meters installed.56 Keeping smart meters working …
Government Response Summary
The government agrees with the committee's observation about the complexity of keeping smart meters working and reiterates existing requirements for energy suppliers to monitor and maintain their metering estate, including In-Home Displays, and mentions ongoing work to develop good practice and track performance.
View Details →
18 Conclusion Acknowledged
The Department identified three main reasons why a smart meter might not be functioning. In June 2023, it told us that approximately 1 million of the 3 million non- functioning meters were new installations where the smart meter is not commissioned when installed, which can be intentional, such as in …
Government Response Summary
The government agrees with the committee's observation that issues can be resolved but primarily reiterates existing efforts and supplier responsibilities for monitoring and maintaining smart meter health, without committing to new specific actions directly addressing the identified categories of non-functioning meters.
View Details →
19 Conclusion Accepted
According to the Department and Energy UK, the third category included around 1.4 million meters that were working at the point of installation but had since lost communication.59 This includes first generation meters, known as SMETS1, that needed to be ‘enrolled’ (in effect, connected) to the central data and communication …
Government Response Summary
The government acknowledges the committee's observation on non-functioning smart meters, agreeing that suppliers should monitor and maintain their metering estate, and highlighting the department's ongoing work to develop good practice, track performance, and Ofgem's role in regulating existing licence conditions. It also mentions seeking agreement on voluntary good practice for In Home Displays, without ruling out future regulation.

20 Conclusion Accepted in Part
Consumers are only guaranteed to receive the benefits available from being able to monitor their energy usage via an in-home display for a year. After one year, if the device breaks the energy supplier currently has no obligation to replace it.65 Ofgem said it encourages suppliers very strongly to replace …
Government Response Summary
The government agrees with the committee's observation, stating it is developing and seeking agreement on voluntary good practice principles for In-Home Display provision beyond the initial 12-month period and has not ruled out further regulation, partially addressing the lack of obligation to replace them.
View Details →
21 Conclusion Accepted
The Department also estimates that 7 million communications hubs (a modular component of the smart meter set) will need to be replaced in the South and Central regions ahead of 2033, when 2G and 3G communications networks are closed. These will be replaced with an equivalent module which communicates using …
Government Response Summary
The government acknowledges the committee's observation on 4G communications hub replacement, stating that suppliers have an existing obligation to prevent loss of connection, and that the government is already facilitating and supporting suppliers in developing their replacement plans, which will culminate in detailed plans by 2026.
View Details →
22 Conclusion Accepted in Part
The government first announced its intention to mandate suppliers to install smart meters in 2008, and energy suppliers have been rolling out smart meters since 2012.70 The Programme has therefore been active for more than a decade, and although the Department has produced seven cost-benefit analyses, it has not done …
Government Response Summary
The government agrees to share annual cost and benefit information with Parliament by Summer 2024 to provide visibility on the smart metering rollout. However, it does not explicitly commit to producing a full new cost-benefit analysis since the last one in 2019, instead referencing the 2019 analysis as comprehensive.
View Details →
23 Conclusion Accepted in Part
At our evidence session, the Department could not provide an up-to-date figure for the Programme’s costs and benefits. It considers that both costs and benefits will have increased since 2019, given: a) lower installer efficiency and delays during COVID-19 increasing costs generally, together with higher than anticipated labour costs; and …
Government Response Summary
The government acknowledges the committee's finding that up-to-date cost and benefit figures are not available, and, treating this as a recommendation, commits to sharing this information with Parliament on an annual basis by Summer 2024. However, detailed plans for bringing the programme to a close will only be shared when they have matured.
View Details →
24 Conclusion Not Addressed
The Department characterises smart meters as a change programme, and recognises that it needs, at some point, to stop being so and become business as usual in the energy retail market.75 However, it considers that there remains significant unsatisfied demand which its current proposed target framework to 2025 recognises, claiming …
Government Response Summary
The government's response details a commitment to share annual cost and benefit information and plans for program closure, which does not address the committee's observations regarding differing views on smart meter demand and rollout pace.
View Details →
25 Conclusion Accepted
As well as the approach to the rollout there are other significant issues for the Department to consider after 2025, including the re-licensing of the DCC (the central communications and data platform), and reform of the industry code governance. Ofgem has a key role to play in both of these.80 …
Government Response Summary
