SMDA Website Refresh

Dear SMDA Scheme Members

In our February update we informed Members that we were in the process of refreshing the SMDA website, to improve its usability and accessibility to information.

We are pleased to say that these changes are now live.

As part of this update, log in passwords for individual users had to be reset, therefore, when you next log in you will find that your old password will no longer work. To login, please use the ‘Forgotten Password’ weblink to gain a new password, which can then be amended to something more memorable using the ‘Edit My Profile’ link under your site profile.

Please contact if you have any questions or if you have any difficulties in accessing the website.

Best Wishes,

SMDA Mid-Month Update – 12th March 2019

Dear SMDA Scheme Members

We are writing with a mid-month update due to some good news regarding the SMDA scheme.

Test House News

Following our update at the end February that we had reached final agreement with the SMDA Test House we can now confirm that the Test House, NMi, has officially rescinded its termination notice.

This is good news for the SMDA scheme as we now have a stable pathway for testing. With the potential uncertainty removed, we now want to encourage the submission of devices for testing.

As Members will be aware, device submissions are essential for the viability of the SMDA scheme and we hope that this news will provide confidence to those that have previously been uncertain about submitting their devices for testing.

To request a quote for device testing please contact

Please contact if you have any questions on the information in this update, otherwise we will issue the next full update at end March.

Best Wishes

Catherine Cousins, Interim Head of SMDA Scheme

SMDA Monthly Update – February 2019

Dear SMDA Scheme Members

This is our second monthly update, which provides an overview of the latest scheme news and activities. If there is anything additional you would like to see in future updates then please do let us know.


Path to Partial Assurance – Progress Update

Following three weeks of intensive testing and triaging by both the SMDA SO and Test House, we have now managed to overcome device joining issues that were hindering progress and have completed credit interchangeability testing for the majority of device combinations.  This is a big step forward from where we were last month. We are still encountering interchangeability issues, for example incorrect tariff pricing and historic consumption issues, but have developed an initial approach for partial assurance subject to the remaining issues being resolved, which has been presented to the SMDA Management Panel today.

We will continue with internal triage, liaising with manufacturers and liaising with the DCC to resolve these issues and to confirm the first baseline for partial assurance. We are holding an interchangeability session with the DCC and Early Mover Model manufacturers in the second week of March and intend to release a further update in mid-March.


Other Activity 

  • Website – Changes to the SMDA Website will shortly be made live. These changes aim to make access to information easier and ensure information available is useful. If you have any feedback regarding the website please contact
  • Membership – Two new scheme membership applications have recently been successfully completed, meaning there are now 43 SMDA Scheme Members


Test House News

  • Following successful completion and validation of all HCALCS test scripts, subject to final SO verification, the Test House will have now completed all test development for the full scope of SMDA under both CSP networks, which is good news.
  • We have reached final agreement with the SMDA Test House to ensure they can remain in the scheme, despite commercial pressures due to lower device numbers than expected being submitted for testing. We are in the process of finalising documentation and once this is complete will issue an update.


Recent and Forthcoming Meetings

  • SMDA Management Panel meetings were held on 11th and 28th February
  • The SMDA SO presented at the EUA Members meeting on 19th February to provide a scheme update
  • The SMDA Co Board will be meeting on 4th March


Please contact if you have any questions on the information in this update, otherwise we will issue the next update at end March.


Best Wishes
