Customer Change Team Leader


The Government has proposed the EPG (Gas) Scheme, for domestic customers, to secure reductions in the energy bills of domestic customers within Great Britain. The intention is for the Central Data Service Provider (CDSP) to perform the function of the EPG (Gas) Scheme (the ‘Scheme’) Administrator and that the scheme to be implemented by 1st October 2022.

Modification 0824 confirms the role of the CDSP as the Scheme Administrator for the EPG (Gas) and gives them the relevant powers to make changes under the DSC in order to facilitate implementation and administration of this Scheme, from 1st October 2022, in line with the Government direction.

This change proposal seeks to design, build and implement the relevant functionality and processes in order for the CDSP to fulfil its role as the Scheme Administrator.
