TESSA online systems for ACPs

TESSA has replaced the ESS Portal, ESS Registry and ELT Portal. As an Accredited Certificate Provider (ACP) you can use TESSA to:

We have developed a series of learning modules (see below) to help you get started in TESSA. Troubleshooting support is also available (see the TESSA page for more details).

Please ensure contact details are kept up to date to ensure you receive all relevant communications relating to your accreditations and the Energy Security Safeguard Schemes.

Logging into TESSA

To access TESSA, you need a TESSA user account comprising a username and password. This needs to be tied to a valid and unique email address. The security feature requires one account (email address) per person accessing TESSA and a single email address cannot be used to access more than one TESSA account.

Existing ACPs should use the new user account and login details (username and password) emailed to the primary user (this is your primary contact in the existing ESS systems) on 5 September. See learning module 2 below for more details.

If you are applying to become an ACP, see the How to register an account page for detailed instructions and to watch a video showing how to register an account.

Your customer admin user in TESSA can set up additional user accounts for other users in your business who may need to access TESSA (see learning module 3 below).

You will also need to set up a signatory user in TESSA to submit an application for accreditation or an application to amend an accreditation.

TESSA changes for ACPs
Uploading implementation data

There will be changes to how you upload implementation data in TESSA:

  • you will need to include additional information in the implementation data upload for certificate registration
  • your implementation data will need to be in a CSV file format so that it can be uploaded into TESSA, instead of the current spreadsheet template.

See Implementation Data Upload for more instructions on how to format your data before uploading in TESSA.

Processing payments after registering a certificate
  • TESSA will include a new online payment system to process payments after registering certificates.
  • To complete the certificate registration process, you will need to pay by credit card, PayPal or PayID. Payment can be immediate, and the system will generate an instant invoice for your records.
