Switching Programme

It is vital that energy consumers can easily, and with confidence, switch their energy supplier. Switching strengthens competition in the energy market, which in turn benefits consumers.

The current switching arrangements, developed in the late 1990s, are complex for suppliers and can lead to delays, errors and costs, which are often borne by consumers. 

Through the Switching Programme we are taking steps to radically transform current switching arrangements, and deliver faster, more reliable switching for consumers.

You can access all consultations and decisions related to the programme, along with documents from ad hoc workshops, in the publications and updates section below.

Enactment Phase governance

The governance requirements for the programme are different for the different phases. During the Enactment phase, governance will undergo a staged transition towards the proposed DBT phase governance structure. The intention is that the higher-level decision making bodies, such as the SRO, advised by Programme Board and the SPDG will continue, with a membership and Terms of Reference refresh.

Our proposed governance structure is illustrated on page 85 of the Switching Programme Outline Business Case and Blueprint phase decision. Ofgem is currently in the process of finalising the Terms of Reference refresh, which we intend to publish shortly.

Design principles

To guide our assessment of the options being developed for the new switching arrangements, we’ve developed design principles.

Archive: Blueprint and DLS Phase


The Blueprint and DLS Phases were used to establish the policy, and define the design and delivery requirements, that will underpin the new switching arrangements. We have provided the key document and programme information from these phases below: please note these link do not provide the latest Programme position or versions of Programme documents (these can be found above, under Programme Scope). 

Blueprint and DLS Phase Scope

Stakeholder Engagement - Archive

In May 2016 Ofgem modified the Data Communications Company (DCC) licence to set out new obligations for DCC’s role in the Switching Programme. This requires DCC to contribute to the design of the Central Switching Service providing a platform for fast and reliable switching and to procure the Relevant Service Capability that will underpin the new arrangements. We are proposing to further modify DCC’s licence to set out its role during DBT and early years of live operations.

The Switching Programme is now in the Enactment phase and DCC will be commencing the procurement of services. An initial pre-qualification stage will be used to shortlist applicants to receive an Invitation to Tender (ITT) for the services being procured. A selection (pre-qualification) questionnaire (PQQ) will be published late June.
