Energy data services

Our range of data solutions are designed to work with whatever types of meters are in use – be it electricity or gas, smart or pre-smart. We can reliably transfer valuable data out of the home and into the cloud, so that it can be used in new and innovative ways. The data can then be presented to your consumers in a highly engaging way – either through our own user-focused apps or apps you develop yourself.

Customers wishing to integrate the geo offering with their own platforms, apps and 3rd-party services can do so using data queues and REST APIs.
