The SEC states that if you are a Supplier or a Network, you are required to become a Party to the SEC
in order to fulfil your Ofgem Standard Licence Conditions (SLCs).
Our Party Engagement Team is available to help guide you through the accession process to become a SEC Party.
There are five SEC Party categories:
• Large Supplier
• Small Supplier
• Electricity Network
• Gas Network
• Other SEC Party
The SEC Accession Process is based on a simple 3 stage process:
- ✓ Submit an Accession Application Form to the SECAS Helpdesk containing your contact, organisation & license information.
- ✓ Submit the Application fee of £540 (and £1 payment for a share in SECCo, which is
obligatory for Energy Licensees and optional for non-Energy Licensees)
- ✓ Receive an Accession Agreement by email from SECCo
- ✓ Sign but do not date two copies of the Accession Agreement
- ✓ Return both copies by either email or post
- ✓ Receive countersigned Accession Agreement from SECCo after next SECCo Board meeting (typically occurring the second Friday of each month)
- ✓ Receive the Share Certificate (if applicable) for SECCo
- ✓ Receive Party Signifier and ID Allocation EUI-64 Compliant identifier range
We recommend that you submit the signed Accession Agreement to SECAS at least one week before the SECCo Board Meeting to ensure that you will accede to the SEC at the next Board Meeting. Please check the Meetings Calendar for dates.
Where to begin your accession?
Please read the Guidance Document available below. Once you have completed the Accession Application Form, please send it to our Helpdesk along with the relevant Accession Fee by either email or post. The Accession Fee can be paid by either electronic bank transfer or cheque. If you are posting, please send the required documents to the following address:

Once an Applicant accedes to the SEC, they will be allocated an EUI-64 Compliant Identifier range and Party Signifier. They will then be eligible to start the User Entry Process in order to become a DCC User.
