Latest update On 24 June 2020, the Change Board voted to approve this modification under Self-Governance. This modification will be implemented in the November 2020 SEC Release.

What is the issue?

The implementation of SECMP0006 ‘Specifying the number of digits for device display’ resulted in amendments to the Smart Metering Equipment Technical Specifications 2 (SMETS2) to standardise the number of digits used to display Consumption Registration on a User Interface.

The SMETS allows the use of Large Gas Meters at Domestic premises. However, some of the Large Gas Meters are unable to measure to thousandths of a metre cubed. Equally, due to the greater flow rate, they require more than the five most significant digits to meet the Measuring Instruments Directive (MID) requirements. This means the current requirement in the SMETS to have only five digits before a decimal point conflicts with the MID requirement.

What is the solution?

This modification proposes to amend Section 4 of the SMETS, to make Large Gas Meters exempt from the User Interface requirements for consumption information.
