The statutory consultation by Ofgem on smart metering Guaranteed Standards of Performance closed on 12 September 2025, according to the Department for Energy Security and Net Zero's consultation document on the post-2025 smart metering policy framework1. The document states that Ofgem's statutory consultation was published on 8 August 2025 to close on 12 September 20251. The department's own consultation, issued on the same date, remains open for responses until 11:59pm on 3 October 20251.
The department's document defines Guaranteed Standards of Performance as regulations that require energy suppliers to meet specific service standards, such as fulfilling requests for appointments, and provide compensation to consumers if they fail to do so1. The wider consultation proposes licence condition amendments covering a strengthened Operational Licence Condition, a 2030 obligation on suppliers to complete the domestic rollout, and a requirement on suppliers to submit annual deployment plans1.
The existing Smart Meter Targets Framework, set out in gas and electricity supply licence conditions, requires suppliers to have delivered smart meters to 74.5% of relevant domestic premises in Great Britain by the end of 2025, at which point the framework comes to an end1. The document records that 3.5 million smart meters were operating in traditional mode across Great Britain at the end of March 2025, representing 9% of all smart meters1. It also states that the percentage of smart meters operating in traditional mode has been gradually reducing since autumn 2024 as a result of actions taken by suppliers1.
The document notes that Ofgem's compliance engagement against six large suppliers was initiated in July 2024 under the existing Supply Licence Conditions1. It also records a requirement on energy suppliers, in place since 1 October 2024, to provide all smaller organisations with smart meters with free and regular information on their energy use1. The government states it has engaged with Ofgem in developing its consultation1.

Why it matters for households
Guaranteed Standards of Performance sit behind the practical experience of having a smart meter installed and kept working: appointments kept, faults addressed, and compensation where a supplier fails to meet the standard1. For a household, the difference between a meter that reports remotely and one that does not is the difference between automatic readings and manual ones, and between access to updated tariff information on an in-home device and its absence1. The 3.5 million meters in traditional mode at the end of March 2025, 9% of the total, are meters where the supplier cannot obtain remote readings as expected or the consumer cannot access their energy information across the home area network1. The department says that figure has been falling since autumn 20241.
The proposed 2030 obligation would extend supplier duties to install smart meters in remaining domestic premises, with the existing targets framework ending after 20251. The rules that govern supplier obligations are set out in the smart meter rules and supplier obligations guide, and the standards covering fault repair times are covered in smart meter guaranteed standards. Ofgem's wider role is explained in what the energy regulator does and what it covers.
What happens next
Responses to the department's consultation are due by 11:59pm on 3 October 20251. The document states that in 2026 the DCC will launch a Virtual WAN service, an arrangement where, with consumer consent to use their broadband, smart meters can connect to the DCC via the internet, for premises with no wide area network coverage1. It also refers to the switch-off of 2G and 3G mobile services by end of 20331. The outcome of Ofgem's statutory consultation has not been reported in the document1.
