Stakeholder Information

Asbestos guidance


Following a series of industry meetings, guidance has been developed to document the industry developed approaches to managing asbestos during metering activities.

This guidance has been developed to enable participants to incorporate the information into their own company's health, safety and environmental management system. This document does not form a standalone policy. Companies will need to amend or adapt the guidance to suit their own management system. It is for individual companies to ensure that they comply with the law. If any reader believes any advice in this document is contradictory to legislation, then please highlight the concerns to the author.

Meter box specifications


Many manufactures produce electricity and gas meter boxes, a search of the internet will list several manufacturers/suppliers. Standard meter boxes are available from many builders merchants. BS 8499:2009 Specification for domestic gas meter boxes and meter bracket, was published in 2009 and BS 8567:2012 Specification for outdoor electricity meter cupboards, was published in 2012.

Removal of the cut-out fuse to fit an isolator switch or change a consumer unit


Electricians are not permitted to remove the cut-out fuse to fit an isolator switch or change a consumer unit. To remove the cut-out fuse the security seals will be broken, this is not only dangerous but can leave you and/or the property owner liable to prosecution for energy theft. A review occurred in 2009 which has resulted in publishing a document aimed at electricians - go to DCUSA.

Electrical connections to gas meters


Making electrical connections to gas meters must be made by a suitably qualified person, who is acting within the various rules, laws, regulations, directives and standards that relate to hazardous areas and intrinsic safety. Guidance can be sought from the IGEM document GM/7. You must contact the owner of the equipment for permission prior to making any electrical connection. In April 2010 the AMO produced a model agreement for making a connection, a copy can be found below. Existing connections must not be disturbed without permission of the meter owner.

Length of meter tails


The meter tails should be as short as possible. Different metering companies have different policies but the length should always be less than 3 metres of cable from the cut-out through the metering equipment to the consumer unit. A example may be 1m of cable from the cut-out to the meter, then 1.5m from the meter to the consumer unit. The meter tail cable size must be consistent. BS7671 Reg. 434.2.1 gives some guidance. If the consumer unit is required to be further away, then a switch-fuse unit should be installed close to the meter and a sub-main compliant with BS7671.

Sub-meter standards


Statutory Instrument SI1679:2006 & SI2647:2006 applies, "…3. — (1) A "relevant instrument" is an active electrical [or gas] energy meter which is for use for trade." This means sub-meters are within the scope of the SIs when used for trade. In practice, where the owner of a multi-building commercial premises installs sub-meters to determine each building energy use. If these meters are used for energy management purposes then they do not need to comply with the SIs. If the owner then rents out one of the buildings to a tenant and uses the meter from recharging the energy to that customer then the meter is used for ""trade‟ and, to be a legal trade, the metering should comply with the SIs.

Reverse running meters


The AMO have participated in work with other industry stakeholders and regulators to investigate where meters run in reverse. See FAQ for links to other stakeholder information. The AMO have prepared a technical document which explains the background and detail of the issue. The AMO has also published a list of suspect meters, this has been revised in September 2014 see the update document which shows the changes.  The list is now published as two documents, the shorter list only showing the meters which are suspect, and a longer list showing all the meters based upon a list from the NMO Schedule 4.
