The rollout of smart meters across Great Britain has reached a major milestone, with new government statistics revealing that 70% of all gas and electricity meters in homes and small businesses are now smart or advanced devices.
According to the latest quarterly report from the Department for Energy Security & Net Zero, more than 40 million smart and advanced meters were in operation by the end of September 2025. Of these, 37 million are actively operating in smart mode, giving consumers real-time insights into their energy usage and enabling more accurate billing.
Installation Pace Slows as Market Matures
During the third quarter of 2025, large energy suppliers installed 680,000 smart and advanced meters—a figure that marks an 8.2% drop compared to the previous quarter and a 4.7% decrease year-on-year. Analysts attribute this slowdown to the increasing saturation of the market, as the majority of properties have already made the switch.
In the domestic sector, 64% of all meters operated by large suppliers are now smart meters in smart mode, with the figure rising to 70% when including those operating in traditional mode. For non-domestic sites, 59% of meters are smart or advanced, rising to 62% when traditional mode is included.
Supporting a Greener, Smarter Energy System
The government describes the smart meter rollout as a “critical national infrastructure upgrade” that supports the transition to a cheaper, cleaner, and more reliable energy system. Smart meters not only help consumers manage their energy use and reduce bills, but also enable the integration of renewable energy sources and flexible tariffs.
The report highlights that the majority of first-generation (SMETS1) meters have now been migrated to the national Data Communications Company (DCC) network, ensuring that customers retain smart functionality even when switching suppliers.
