Home energy storage systems make the most of electricity and heat by storing it so you can use the energy when you need it.
They are particularly useful for people with home renewable energy systems who can use more of the low carbon energy they generate at home.
If you already have home renewable energy, an energy storage system could reduce your fuel bills and carbon emissions.
The fuel bill savings are dependent on the system installed and how it is used.
For some new energy storage technologies, there isn’t currently enough independent evidence available to estimate typical savings.
Ask installers to calculate savings for you based on your home and circumstances and to explain how these calculations are done.
Many energy storage systems offer smart operation. This allows you to keep track of your energy use online and to decide when to charge your storage unit and when to draw energy from it.
