Further Questions regarding the Use of the Meter Data Retrieval (MDR) function

On Wednesday 7 May 2025, the MHHS Programme issued a PPIR to request key details on the MDR function from both Suppliers and Smart Data Service (SDS) participants. 

This PPIR is to obtain additional information relating to the use of the MDR Data Integration Platform (DIP) User Role. In particular, the anticipated use of the optional DIP messages in the IF-061 to IF-065 range that may be used to transfer data between SDS and MDR User Roles via the DIP to help support the planning for both Service Activation and DIP Onboard Planning.    

You can view the PPIR form at the link below:

Responses are due by 17:00 on Wednesday 21 May 2025.

The MHHS Migration team is developing Kestrel, the Migration Planning Management Tool, that will provide LDSOs with reporting capabilities for the MHHS Migration later this year.

This PPIR aims to confirm the details for your:

  • Principal Migration contact(s)

To complete this PPIR, please complete the two tables in the email sent to you, to confirm the information on your organisation and your contact and Kestrel user information.

Please return your details via email to [email protected] by Monday 12 May 2025.   

Please note:

  • Any users wishing to access to Kestrel must have an active MHHS account. 
  • To request MHHS accounts/emails (or to re-activate), please email [email protected]
