Ready to Start Testing?

The service is available for electricity and gas smart metering equipment, in-home displays and pre-payment metering interface devices.

The key benefit of obtaining SMDA assurance is that the scheme provides a degree of assurance that devices comply with the Scheme requirements related to the Smart Metering Equipment Technical Specification (SMETS), and ensure smart meter equipment will work effectively and interchangeably in a smart environment.

Manufacturers who wish to commence testing of smart metering devices are invited to contact NMi Certin B.V., the appointed SMDA Test House at smda@nmi.nl.

A Pre-testing service is also now available. This allows Manufacturers to test specific areas of interest, before they commit to full SMDA assurance testing.
