The 21-millionth smart meter installation in Britain took place in July, just five months after the rollout reached 20mn installations since 2012.

There were 210,000 smart meter installations last month – just a thousand more than the month before and 14 percent more than July 2022 (which had the same number of installations as June 2022).

The Data Communications Company (DCC), which operates Britain’s smart meter telecoms network, recently found that smart meters are enabling Britain to cut one million tons of carbon from being emitted every year from energy generation. This finding was based off a government study which revealed that smart meters helped energy users reduce consumption by approximately three percent for gas and electricity.

Installations for 2023 so far have totalled 1.363mn, just shy of the same period last year.

The regions with the most installations last month had a slight rearrangement compared to previous months. East England led the pack again with 33,000 installations, but southern England landed just over 21,000 installations while the east Midlands saw just under 21,000 installations. In prior months, the east Midlands typically had the second-highest installations total across all GB regions.

These figures represent electricity smart meter installations in GB. Visit the Department for Energy Security and Net Zero’s website for the latest dual fuel smart meter reports.

The analysis is based on the D0150 data flows transmitted across our network and we believe capture the vast majority of electricity smart installs.

The users of the DTS have given ElectraLink permission to intercept and analyse this, and other data flows, subject to certain conditions.

Our analysis defines smart meters as those models with the capability to handle time of use tariffs and which can be remotely updated.

For installations after September 2013, we count all meters flagged as SMETS1, SMETS2 or non-SMETS. For installations before the industry standard designation was agreed, the allocation is based on the make and model of meter.
