New report quantifies the future value of smart meters to households

Smart meter owners who are most engaged with their energy use can save up to 20 per cent on their annual bill by embracing a new energy system, according to new research published today.

The report from Delta-ee, the specialist energy research and consulting company, on behalf of Smart Energy GB, includes examples of the new services and technologies that are developing from the digitalisation of Great Britain's energy grid and how these lead to potential annual savings of hundreds of thousands of pounds for households.

Innovations in technology have changed the way the nation engages with day-to-day life. Spotify has revolutionised the accessibility of music, and Netflix has single-handedly brought on-demand TV and cinema into the home. It's now time to view smart meters in the same vein - they have the power to provide a platform for modernisation and new technologies that will transform energy use.

Think tariffs that reward customers for using energy at off-peak times, automatic switching services so households will always be on the best deal, and selling excess energy generated from the home. The possibilities for change that benefit the consumer, the grid and the country are ever-growing, but at their very core rely on the digitalisation of the energy grid through the smart metering system.

Delta-ee's research demonstrates how the changing energy market can lead to potential annual savings of over £200. It also found that annual household savings could include up to:

  • £90 from time-of-use tariffs (£130 for electric vehicle (EV) users) - enabled by customers buying energy when it is cheapest.
  • £100 from peer-to-peer (P2P) energy trading. In the future, customers will be able to buy and sell energy they generate and store with other customers on virtual platforms.
  • £300 from auto switching. Smart meter information will allow companies to automatically work out the best tariffs for individual customers, and then automatically switch them.
  • £75 from smart pre-payment meter tariffs. Pre-payment customers will no longer lose out and have access to the benefits of most other customers.

Dr Andrew Turton, Principal Analyst at Delta-ee commented: "Back when we all first started discussing smart meters it made sense to focus on immediate bill savings. But since then, so much has changed in our lives. People are now used to real-time services enabled by digitalisation rather than simply purchasing physical products. Just as the benefits of music services like Spotify are far greater than not having to but CDs, smart meters are a fundamentally transformative technology and open up a whole host of new services to customers which can benefit their lives and reduce their costs. Without smart meters, customers will be locked out of this future - simply buying kWh of energy, often based on estimates, at a higher cost."

The report assesses the current annual savings by smart meter equipped homes, as well as looking at examples of innovative companies in the UK and abroad who are starting to offer new services to customers which are aimed at providing customers with the outcome they need, rather than only providing energy. For example, heat as a service offerings ensure customers' homes are heated to their required temperatures at a lower cost, without the customer having to worry about owning, maintaining, and replacing their own heating systems. Or auto switching services, where customers never

About Smart Energy GB

Smart Energy GB is the campaign for a smarter Britain. It’s our task to help everyone in Great Britain understand smart meters, the national rollout and how to use their new meters to be cleaner and greener with their energy use. Our national campaign is reaching households and microbusinesses in England, Scotland and Wales.

About smart meters and the rollout

Smart meters replace the traditional meters we currently have in our homes. They enable accurate bills, near real time information on energy use in pounds and pence, and greater control over the way we buy and use energy. The smart meter rollout is an essential technology upgrade, unprecedented in its scale, to improve Great Britain’s energy infrastructure.

There are already almost 12.8 million smart meters installed in homes and microbusinesses across Great Britain. Every household in England, Scotland and Wales will be offered one at no extra cost. Contact your energy supplier about getting your smart meter.
