Second generation smart meters pass 4 million mark

The 4 millionth second-generation smart meter (SMETS2) has been installed onto our secure network. The meter was installed this morning by British Gas in West Malling, Kent.

In the leading localities, take-up of these second-generation meters has reached 1 in 4 households. Bolsover has taken the top spot nationally: its residents are officially the fastest adopters of this technology which is helping households to save energy and go green.

New research has found that take-up of second-generation smart meters increased 13-fold in 2019. SMETS2 meters are fully interoperable and continue to function as smart meters even if the consumer switches energy supplier.

The national secure network underpinning energy smart meters is delivered and operated by the Smart DCC.

Our Chief Executive, Angus Flett, said:

“Throughout last year our network grew incredibly fast, and that’s continuing in 2020. We connected the millionth smart meter in May 2019, and since then we’ve quadrupled the number.

“This milestone reflects the efforts of all involved in the roll-out, including the energy companies and network operators, and those working with us to deliver and operate the network. The progress we’re seeing is also a sign of consumers across Britain making a conscious decision to make their household greener. In some parts of the country, a quarter of homes now have a second-generation meter.

“Our network is a platform for good, and the data flowing across it is paving the way for better use of renewable energy. We believe in making Britain more connected so we can all lead smarter, greener lives.”

Sharon Johnson, Director of Industry Development at British Gas, said:

“Reaching 4 million SMETS2 installations is a significant milestone for suppliers.  We’re seeing first-hand the positive impact smart meters have on helping our customers understand and control their energy use to reduce wastage, whilst supporting the country’s journey to net zero emissions.”

Robert Cheesewright, Director of Corporate Affairs at Smart Energy GB said:

“Smart meters are vital in helping the country upgrade from a polluting energy system to a greener, cleaner one. The installation of the four millionth second-generation smart meter marks an important milestone in the progress of this crucial national infrastructure project. We are grateful that millions of households have played their part by upgrading their home.”

Fast growth in installs

At this time last year our network was still shy of half a million meters. Our growth since then has been very fast, with 2019 seeing a 13-fold increase.

More second-generation smart meters are being installed each week than the total number of red phone boxes ever installed in Britain.


With the increase in meters, the number of messages travelling across our network also multiplied by almost eight times last year. This January, a record 138 million messages were sent to and from SMETS2 meters. The level of traffic in that single month equalled the combined total for January to May 2019.


Today’s roll-out milestone would not have been achieved without the hard work of our customers -- the energy companies and network operators. Other key contributors are our principal service providers: CGI, Telefonica, Arqiva, Critical Software and BT.

Regional data

Adoption of the most modern smart meters is growing rapidly across Britain. The East Midlands is leading the way, with several places reaching a point where 1 in 4 households have a SMETS2 meter. The region is likely to be the first to achieve full coverage.

The top ten areas in Britain for SMETS2 take-up are as follows (each has a concentration of more than 25%):

  1. Bolsover, Derbyshire
  2. Hinckley and Bosworth, Leicestershire
  3. Oadby and Wigston, Leicestershire
  4. South Derbyshire
  5. Blaby, ‎Leicestershire
  6. Tewkesbury, Gloucestershire
  7. Melton, Leicestershire
  8. Rugby, Warwickshire
  9. North Kesteven, Lincolnshire
  10. Charnwood, Leicestershire
