Smart Metering and Gas

Smart meters are the next generation of gas and electricity meters. They are part of the UK Government’s plan for upgrading the UK’s energy system.

The aim is for all homes and small businesses to have smart meters by 2020. 

Between now and 2020 energy suppliers will be responsible for replacing over 53 million gas and electricity meters. This will involve visits to 30 million homes and small businesses.


Video Animation: Sequence for Gas Meter Exchange

This video has been created by the Gas Distribution Networks, not as a training video, but to show the sequence of a gas meter exchange. It has been developed following our GDN members’ experience of attending gas escapes that can be as a result of the gas meter installer not following procedures correctly. Please refer to the GER4 document to identify the top 5 issues that lead to a GDN intervention visit following a gas meter exchange.


ENA GER1, Issue 7 - A Guide for Gas Meter Operatives on Reporting and Acting on Asset Condition Issues 

ENA Gas members produced this guide to help smart meter installers to identify, categorise and report any network related issues. This latest version includes some general updates for A06, which is amended to cover the setting of meter apparatus, and the addition of A07 covering the “ Refusal to Disconnect” and also the addition of References 24 and 25.

Gas Engineering Recommendation GER2 Issue 2 2018

The second version of this guide has been produced collaboratively by the Gas Distribution Networks (GDNs) to support the Smart Meter Programme and smart meter roll out activity. The purpose of the document is to describe the GDN responsibilities in respect of the Business as Usual (BAU) processes that are affected by the introduction of smart meters.  The issues covered have been debated for a number of years at various forums attended by GDNs, suppliers, IGTs, the ENA and EUK. The document brings together some of the conclusions from those discussions.  The document provides the necessary clarity of responsibilities and process so as to minimise any likelihood of inconvenience to the customer.

ENA GER4, Issue 3 - Top 5 Interventions 

Gas Network Operators (GDNs) are required to respond to “smell of gas” calls.  During their investigations on site GDNs may discover that a recent smart meter install has resulted in a gas escape or an unsafe situation as defined in IGEM/G/11. The GDNs will immediately make these situations safe.  GDNs compile the details of these incidents and bring this to the attention of the suppliers involved, on a bilateral basis.  This document highlights the five most common failure modes with the intention of raising awareness of these and inform those parties responsible for managing, mentoring and training meter installers.

ENA GER3, Issue 1 - Guidance for Using Correct Organisation Certificate in the Gas Network Operator Trust Anchor Cells 

Gas Distribution Networks (GDNs) and Independent Gas Transporters (IGTs) have worked with ENA to produce guidance for Suppliers to assist with the selection of the correct Organisation Certificates that should be used in the Network Operator Trust Anchor Cells on the Gas Proxy Function, when installing and commissioning a Smart Meter.
