Switching Business Cases

DCC develops a business case for each phase of the Switching Programme, in consultation with relevant industry stakeholders. These set out the DCC's approach, the roles and responsibilities of DCC and DCC-contracted providers and outlines relevant activities and costs.

Draft DCC Internal Business Case for the Design, Build and Test Phase of the Switching Programme

Last update: 10 April 2019

DCC have developed an Internal Business Case document covering its role as Ofgem’s key delivery partner for the Design, Build and Test (DBT) phase of the Faster, More Reliable Switching Programme. The document sets out relevant DCC activity, and that of DCC-contracted service providers, during the period from June 2019 up to the start of Early Life Support.  An earlier internal business case (and schedule of changes to it) covered activity and resourcing to the end of May 2019.

The document is first provided in draft and intended to illicit feedback from interested stakeholders.
Following consultation, this draft will be removed, and a revised document will be published ahead of DBT. This will then form a baseline scope of work and approach against which our stakeholders can monitor DCC’s delivery progress during the DBT Phase, via the Programme’s governance.  It includes a baseline budget against which Ofgem and stakeholders can monitor DCC’s incurred and forecast costs.

Given the objectives and specific requirements for this programme set by Ofgem, DCC are keen to understand views on the following questions:

  1. Do you believe the activities DCC has proposed in the Business Case match the scale and focus of the role set out under the DCC licence and the REC. Are there any gaps or possible areas of duplications with other parties?
  2. Noting that contingency is not charged upfront, do you feel the level considered reflects the size and likelihood of risk across the DCC part of the programme?
  3. Are the business case's structure and base assumptions clear enough to use in setting a realistic programme budget and forecast charges as part of the ex-post plus regime? Is it clear what DCC is accountable for delivering and how governance will oversee that?

Please send feedback to: by 12pm on 07/05/2019

Revisions to the internal DCC Business Case for the Switching Programme up to May 2019 v1.0

Monday 12 February

DCC has published its rebaselined Business Case for its activities during the Transitional Phase of the Switching Programme. It follows the confirmation of the Reform Package 2a as the preferred solution and sets out the updated planned activities, timelines and costs until May 2019 when the contract for the new Central Switching Service (CSS) is planned for signature. We have developed the Business Case in consultation with Ofgem and industry and we will continue to report regularly to industry and Ofgem to ensure our performance, costs and timelines are kept under close review.

DCC is a key delivery partner for the Ofgem Switching Programme. DCC is contributing to the design of the end-to-end switching arrangements and will be delivering the design and procurement of a CRS which will underpin the new arrangements.
