Switching Programme

Providing faster, more reliable switching for consumers

Welcome to Xoserve’s CSS page. This is the central reference point for our customers on Xoserve’s involvement in, and perspective on, the delivery of Ofgem’s Central Switching Service.

We are committed to keeping our customers fully informed on the delivery of this programme. On a weekly basis, we’ll share our Weekly Progress Report, our Day After Reports (DARs) and our updated view on key risks:

  • Our weekly Switching Programme Status report is the weekly report we’re required to submit to the System Integrator, and we’re sharing here for our customers to have the same update
  • Day After Report summaries of key program meetings are basic notes that we capture during meetings to share with internal to help with consistent knowledge levels across Xoserve, and to provide a contact point if more information is required. We felt that our customers would benefit from seeing these notes should you wish to understand more about Xoserve’s interactions with the programme.
  • Summaries of the key risks are summarised versions of our risk log of topics we believe are affecting the programme and the work that we’re doing to address these risks.

Going forward, we’ll look to widen the information we share based on what our customers are asking to understand. If there are additional updates that you would like, or if you have a comment about any aspect of the programme, please contact Emma Lyndon
