SEC Newsletter 18 April 2019


It’s been a busy financial year for SECAS and a lot of transformation has taken place within our Change Management team.

We recently launched the SEC Modcasts which summarise the recent developments of modifications in the last week, and we’re pleased to say that the feedback received has been very positive. If you haven’t already, you can listen here.


We also introduced the new Development Stage of the Modifications Process which will be supported by the newly established Change Sub-Committee to assess modification problem statements and ensure they are fit for purpose. This newsletter contains details of the first two Draft Proposals that have been raised – we welcome your comments on the issues raised and whether, or how, they impact you.

Look out for the SECCo End of Regulatory Report which will be published in May and many more exciting developments to come!

Before you read on, please note a date for your diary – Thursday 11 July. Look out for an invitation to our Engagement day where you will have the chance to meet with the SEC Panel members, and ask any questions you may have, before the formal general meeting. More information to come…

And that just leaves us to say, Happy Easter!

Two new Draft Proposals raised

As part of our ongoing improvements, we have started using the new Development Stage of the process. The first step is for a SEC Party to email their issue to We will then investigate the root cause and impacts, which will be used to help draft a problem statement for comment.

Since the last newsletter, we have raised two new Draft Proposals:

  • DP071 ‘Second-Comer Charging’ highlights an area of inefficiency in the SEC around rebates for subsequent users of specific services. However, the practicalities of High Volume and Low Volume Gateway connections mean that sharing is not possible. The DCC are required to assess and gain agreement for these costs, leading to delays and inefficiencies in the onboarding service.
  • DP072 ‘Change of Supplier process’ has been raised to look at failures in this process whereby the losing Supplier may still receive information about customer reads and alerts relating to this.

Please contact us with your views on any of the issues raised in the open Draft Proposals, including whether, or how, they are affecting you. Any comments provided at this early stage help to ensure we fully understand the scale of the issue, and what the case for change is, before we spend time investigating solutions. Please email your comments to or call our Lead Analyst for the proposal.


Next monthly Working Group meeting – Wednesday 1 May

At our next monthly Working Group meeting we are planning to discuss the following modifications:
