Smart Meters

The Department for Business, Energy & Industrial Strategy is leading the rollout of smart meters to all homes and small businesses in Great Britain by 2020. This will impact around 30 million premises. Smart meters will enable consumers to see what energy they are using in monetary terms, and will communicate with their energy suppliers on a real time basis. The government expects smart meters to provide a number of benefits for consumers, including helping them to manage their energy use better, ending estimated billing and making it easier to switch between suppliers. In 2016, the government estimated that the rollout would cost £11 billion, and achieve benefits worth £16.7 billion.


This study will:

  • Assess the current economic case for the rollout of smart meters;
  • Look at whether the government is on track to achieve its target to rollout meters by 2020; and
  • Consider whether the government is maximising the chances that smart meters will achieve their intended long-term benefits. The study follows up two previous NAO studies on the rollout, which published in 2011 and 2014.
