A request has been received from a number of Shippers to access specific historic AQ that will assist in identifying whether there has been any temporary impact to the AQ as a result of COVID restrictions.

This data has been requested by the Shipper so that it can be considered in discussions with the consumer and to help validate the accuracy of the current AQ due to uncertainty arising around the current AQ due to the impacts of the Pandemic.

This access would be for a defined period, so these parties may obtain a “pre-COVID AQ” value for SMPs. The Pre-COVID AQ value would be determined as the ‘Rolling AQ’ that was effective on 1st April 2020 – having been derived as part of the March 2020 AQ Calculation or earlier.

It is anticipated that this service will conclude on 01 October 2022


Disclosure Request Report; DRR-SEP21-01 was approved by Contract Management Committee (CoMC) at the September Extraordinary meeting. This allows the CDSP to release the Rolling AQ that was effective on 01 April 2020 to a Shipper where they have requested it.


This Change Proposal has been raised in order to put in place the process to deliver this service to Shippers.
