The听Tariff Interoperability听(TI)听consultation sets out how the policy听objectives听would be achieved. There were 25 respondents to the 18 questions. Respondents included suppliers,听optimisers听补苍诲 trade bodies, some of which听represented听a collection of industry stakeholders.听听

Government welcomes the broadly positive and supportive response from听the majority of听stakeholders, and the strong endorsement of the project鈥檚 strategic听objectives.听The majority of听comments related to ensuring the technical detail set out in the consultation delivered on the government鈥檚 policy intent in practice.听

The most significant elements of feedback related to the practicality of the proposed delivery timetable and to the synergies between the Tariff Interoperability听proposals and government鈥檚 wider digitalisation agenda. In summary, stakeholders suggested delivery timelines were too tight and that there would be duplication of efforts as the consumer consent aspect of the TI Arrangements,听would be delivered in听parallel听to听the Consumer Consent Solution (CCS, also being delivered by听RECCo)听which addresses the same need.

Tariff Interoperability will support consumer-led flexibility by standardising how electricity tariff pricing data is shared across the market. This will make it easier for optimisation services and Energy Smart Appliances (ESAs), such as electric vehicle chargers, heat pumps and battery systems, to respond to electricity price signals using consistent, machine-readable tariff data, helping consumers reduce bills and optimise energy usage.听

Following consultation feedback,听the听Department for Energy Security and Net Zero听(DESNZ)听补苍诲听the Retail Energy Code Company听(RECCo)听have updated听the implementation approach for Tariff Interoperability听in a number of ways. The most substantial change is听to support a more manageable delivery timeline and alignment with the Consumer Consent Solution (CCS).听As a result we are听breaking听down听phase 1 into听a public and private data route听to access tariff data:听

Phase 1a 鈥� Public Tariff Pricing Data听-听Go-live: 18 February 2027

• Phase 1a introduces听standardised听access to Public Tariff Pricing Data through Supplier听Application Programming Interfaces (APIs).听This enables听optimisation听services and Energy Smart Appliances to use tariff pricing data where consumers can share their Supplier and tariff details.听

Phase 1b 鈥� Consumer Specific Tariff Information听-听Planned go-live: November 2027

• Phase 1b will introduce the ability for consumers to consent to the sharing of Consumer Specific Tariff Information with听authorised听third-party providers through CCS-aligned arrangements. Further consultation on the Phase 1b arrangements will take place later in 2026.听

On 18 May 2026, DESNZ will introduce the new SLC11C provisions and听will implement REC Schedule 35 into the Retail Energy Code.
