Central Products List »

Central Products List

In accordance with SEC Section F2 and established and maintained by (SECAS on behalf of) the SEC Panel, the Central Products List (CPL) is a list of:

(a) the SMETS2+ Device Models for which the Panel has received all the Assurance Certificates1 required for the Physical Device Type relevant to that Device Model (known as the Certified Products List); and

(b) in the case of SMETS1 Device Models, those Device Models for which the Panel has received all the information required in accordance with the CPL Requirements Document (which does not require any certification of SMETS1 Devices under the CPA or any other assurance scheme).

The CPL will have two primary SEC-defined uses:

  • informing SEC Parties of which Device Models are currently assured in line with SEC requirements; and
  • acting as a means for the DCC to manage their Smart Metering Inventory, controlling the Devices with which they can communicate.

Please note there may be a delay between the published CPL on this web page being uploaded by the DCC into its Data Service Provider (DSP) System.

Live Workbook

Following the designation of SEC Appendix Z – CPL Requirements Document on 27th October 2016, the CPL is now live.

The latest version of the workbook will always be available on this page. Please note that the structure and content of the CPL is defined within the SEC Subsidiary Document, the Certified Products List Requirements Document (SEC Appendix Z).

Individuals wishing to submit a Device Model for inclusion on the CPL should familiarise themselves with the submission guidance, available at the bottom of this page. If any further assistance is needed, please contact the SECAS helpdesk.

The latest version of the workbook can be downloaded from the end of this page. The CPL exists as a workbook which includes a number of tabs:

  • the first tab provides version control information and details of changes made between versions;
  • the second provides the listing of Device Models, as described in SEC Section F2.1 and the CPL Requirements Document;
  • the third tab acts as the submission form (please see the ‘New Entry Form’ details below and the submission guidance for further information); and
  • the final tab provides the same information as the second tab, re-structured into a format agreed with the DCC for the purpose of their management the Smart Metering Inventory, as described in SEC Section F2.9. Further detail is available below.

Changes to the content requirements of the CPL will be managed via the SEC Section D ‘Modifications Process’.

New Entry Form

The CPL Workbook also includes the form which organisations must complete as part of the process of adding a new Device Model / Device Type combination to the CPL.

The fields in the New Entry Form are identical to those on the CPL itself. However the form provides guidance on how fields must be completed and also prevents the completion of values which must be assigned by SECAS, such as the CPL entry number and entry status. Validation rules are applied when completing the form, informing the user and preventing invalid values from being entered.

It is envisaged that new entry forms will be emailed, alongside the required assurance certificates and any additional supporting evidence or Release Notes, to SECAS – SECAS@gemserv.com.

Version Control and export to .csv

A Version Control tab is included in the CPL Workbook. This assists SECAS with its configuration management and provides a level of traceability for all versions of the CPL, as well as providing a specific record of all changes made.

At the request of the DCC, a tab allowing the export of the CPL to CSV format has also been included in the CPL Workbook. The tab cannot be edited and is based solely on the relevant parts of the CPL itself. However, it is formatted in such a manner which allows it to be saved as a CSV file. This option has been included to facilitate the DCC’s import of the CPL into their systems for the purpose of managing the Smart Metering Inventory.

Firmware Information Repository

In accordance with SEC Section F2.14 – F2.17, SECAS (on behalf of the SEC Panel) have established the Firmware Information Repository (FIR).

The FIR is a list of Meter Manufacturer contact details and firmware information associated with a Central Product List (CPL) entry. It is intended to provide gaining Suppliers information to identify the relevant Meter Manufacture to contact with regards to the latest firmware on a Device following an update to the CPL.

The associated mandatory fields that make up the FIR are required to be provided as part of a CPL New Entry form by a Party of any other person who is submitting a Device for addition to the CPL. This information will be used by SECAS to populate the FIR alongside the CPL.

The FIR details are only required for Metering Devices and must be included as part of the CPL Submission for the following Devices:

  • ‘Single Element Electricity Metering Equipment’
  • ‘Twin Element Electricity Metering Equipment’
  • ‘Polyphase Electricity Metering Equipment’
  • ‘Gas Smart Meter’

The FIR is published and available for download in the Document section and is available to SEC Parties only, which means access is only granted with a valid login to the SEC Website.

Further detail is available in the Central Products List Submission Guidance v1.4 below.


CPL Meter Model entries mapped to a UK Metering Forum (UKMF) supported ‘plain English’ description

To aid SEC Parties and other interested parties understanding of CPL Meter Model entries the UKMF has worked with SECAS to provide a means to map Meter Model instances contained in the CPL (in the SEC required format) to a industry wide understood ‘plain English’ description.

The product of this work with the UK Metering Forum (UKMF) has led to the develop of a supporting spreadsheet to the CPL. The mapping spreadsheet contains three tabs:

  • the first tab provides version control information and details of changes made between versions of the mapping spreadsheet;
  • the second tab provides the Zigbee Manufacturer Codes, that have been/are provided by Manufacturers. (Note that the inclusion of this tab supersedes the previously published Zigbee Manufacturer Code list document); and
  • the final tab provides the listing of Meter Models from the CPL mapped to the UKMF supported plain English description (see columns A and B of the spreadsheet tab).

This spreadsheet is provided below and will be updated in parallel to the CPL submission process, in collaboration with the UKMF, when new instances of Meter Model hardware is submitted and added to the CPL.

Please note that this is a supporting document and does not replace or alter the role of the CPL within the SEC and the end to end Technical and Business Architectures and associated processes.

Please note that this mapping spreadsheet includes hardware instances of Meter Models (ESME and GSME) only.

It does not include:

  • mapping of the different firmware iterations associated with a specific Meter Model hardware version; and
  • mapping for Communications Hubs or Prepayment Prepayment Interface Devices (PPMIDs).


1 Devices will require one or more of the following three Assurance Certificates. Requirements depend on the nature of the Device and are defined in Smart Metering Equipment Technical Specifications and Communications Hub Technical Specifications.

Commercial Product Assurance (CPA) Certificates: Required for all Devices other than Prepayment Interface Device (PPMID) and Type 2 Devices

Device Language Message Specification (DLMS) Certificates: Only required for Single/Twin/Polyphase Electricity Smart Metering Equipment

Zigbee: All Devices
