British energy suppliers have carried out over 18 million smart meter installations since the programme began a decade ago.

The latest milestone was achieved in April 2022 with 186,000 installations taking place – even though momentum has waned slightly with figures 17 percent less than March 2022 and 15 percent less than the same month last year.

This comes as suppliers continue to be under pressure from the regulator to deliver on targets for smart meter installations. In March, Ofgem issued an open letter to suppliers on obligations to deliver the smart meter rollout. Ofgem remains optimistic and believes suppliers with recent SoLR customers could still meet targets set for 2022.

The regions with the most installations last month included East England with 24,000, Southern England with 20,000 and the East Midlands with 18,000 in line with trends over the past few years. Regions with the highest number of cumulatively installations include East England with 2.165mn, the East Midlands with 1.833mn and Southern England with 1.83mn.

These figures represent electricity smart meter installations in GB.

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.
