MP123 IVP realignment of SMETS2 v2.0 and v3.1

Proposer Alastair Cobb
Lead Analyst Alison Beard
Date raised 27/03/2020
Implementation date 29 May 2020
Latest update

What is the issue?

The Smart Energy Code (SEC) sets out the Smart Metering technical specifications. To ensure interoperability, the dates which these technical specifications can be used are set out within the SEC.

Due to social distancing restrictions Suppliers are not installing as many Devices as anticipated. This has led to a build up of stocks of SMETS2 v2.1 and 3.0 Devices in teh supply chain which cannot feasibly be installed by the IVP and MVP end dates. Additionally, due to an unforeseen delay in the development of SMETS2 v4.2/ GBCS v3.2 Devices the Installation Validity Period (IVP) and Maintenance Validity Period (MVP) for these Devices as currently set out will cause a significant interruption in the supply and installation of Devices.

What is the solution?

The proposed solution is to extend the IVP end-date for SMETS2 v2.0 and SMETS2 v3.1 Devices. This will allow Device manufacturers and Suppliers to use up existing stocks of SMETS2 v2.0 and v3.1 Devices, reducing cost and wastage within the industry. The date will be extended by six months from 27 October 2020 to 27 April 2021.
