StageRefinement Process
Implementation date Unknown
Latest update This Modification has entered into the Refinement Process as of 19 June 2020. The solution is being developed with the proposer.

What is the issue?

Only the relevant Supplier (or their agent) holds the SMKI Private Keys that enable Critical Commands, such as Emergency Credit, to be sent and actioned by the meter. It can commonly take between two and four weeks from the point of SoLR appointment for the new Supplier to change the SMKI Certificates and much longer in some instances where there are problems with data and communications. During this time Prepayment meter customers may be off supply.

Who is impacted?

Large Suppliers and Small Suppliers
