Keep your SEC Party Details up to date

Thank you to all those who have updated your SEC Party details. SEC Parties are reminded to ensure your contact details are kept up to date with SECAS (in accordance with SEC Section M6.2) and the DCC. This is vital to ensure that your Party receives important updates, information, and invitations to industry meetings and events.


If you have not yet updated your Party details, please do so by using our online form. This form will also allow you to state if you provide your consent for us to inform the DCC and Alt HAN, if applicable, of any changes to your Party.

If you have any questions, please contact the SECAS Helpdesk.


New Draft Proposals

There have been five new Draft Proposals raised since the last Newsletter. You are invited to provide feedback to help us understand whether the issue affects your Party. Please contact the Change Team to share your views.



DP165 ‘ESME Voltage Accuracy’



Electricity Network Parties are obligated to ensure that the voltage supplied to consumer premises from low voltage electricity networks is between defined limits.

Electricity Network Parties have requested that average Root Mean Square (RMS) voltage readings from Electricity Smart Metering Equipment (ESME) be recorded with a mandated level of accuracy. This is not currently codified in the Smart Metering Equipment Technical Specifications (SMETS) or the Great Britain Companion Specification (GBCS).




DP166 ‘Adverse Weather Planned Maintenance Process’



High Impact Planned Maintenance includes activities that directly affect any DCC Services involving end-to-end communications. This disruption will impact consumers as well as SEC Parties. Currently there is no defined process that allows the DCC to postpone High Impact Planned Maintenance activities due to adverse weather conditions.




DP167 ‘Review of SEC documents’


The Proposer has identified areas that appear to be no longer applicable to the SEC. Ofgem has also raised an action for SECAS to review the SEC and rationalise where possible. This Draft Proposal will review the SEC and identify areas that could potentially be removed from the Code.




DP168 ‘CPL Security Improvements’


SEC Appendix Z ‘CPL Requirements Document’ requires the Panel to check that a communication requesting a firmware Image to be associated with a Device Model on the Central Products List (CPL), originates from the person who created the Image and is endorsed by a Supplier.

At present, the signatures used by manufacturers do not enable cryptographic authentication that the communication originates from a specific manufacturer. Neither a Supplier nor the Panel can thereby authenticate the communication and therefore fully meet the SEC obligation.




DP169 ‘Managing SEC Obligations and the Consumer’s Right to refuse a Smart Meter’


Consumers have a right to refuse a Smart Meter. Suppliers are unable to comply with consumer requests to install a Smart Meter in ‘dumb’ mode.

The SEC does not currently allow for the Devices on the Smart Metering Inventory (SMI) to be either installed and not commissioned, nor to fit the meters without also fitting the DCC provided Communications Hub. There is no concept, by design, of fitting a Smart Meter in ‘dumb’ mode.



Open Industry Consultations Webpage

Please visit our Open Industry Consultations webpage for details of consultations that may be of interest to SEC Parties. If you are aware of a consultation that should be added, please contact the SECAS Helpdesk.

Opportunity to share your feedback on DCC Customer Engagement

How has the DCC engaged with SEC Parties over the past regulatory year? SEC Parties are invited to share your views on this with Ofgem and SECAS. As part of the changes to the DCC Operational Performance Regime (OPR), Ofgem has asked the SEC Panel to provide an assessment on how well the DCC engaged during the 2020/21 Regulatory Year. You can find more information about the consultation here.


Please email your completed response form to with the subject line ‘OPR – DCC Engagement Consultation’ by 5pm on 14 July 2021. If you have any questions, please contact the SECAS Helpdesk.
