The Smart Metering Device Assurance Scheme

The SMDA Scheme has been set up to provide assurance to consumers, suppliers and financiers that smart meter equipment will work effectively in a smart environment. The Scheme provides assurance testing of smart metering equipment covering both interoperability and interchangeability of the devices.

Interoperability is an obligation on energy supply companies, which requires the ability to demonstrate that smart metering devices that interact with the Data Communications Company (DCC) systems can successfully receive, interpret, act on and respond to messages. Interchangeability testing checks that all devices on the Home Area Network (HAN) can communicate with one another and interpret and act on commands. It is beneficial to the industry in order to reduce the risk of ‘stranded’ assets.

The Scheme was established after a number of suppliers, meter manufacturers and funders of smart meter programmes identified a common benefit in establishing a central assurance regime. More details around this can be found under the About section of the website.
