Supplier data portal: clearer information, better insight for suppliers

Access to clear, consistent data helps energy suppliers understand performance, identify trends and see how they compare with the wider sector.

At Energy Ombudsman, we're developing a new self-service supplier data portal that will bring key information together in one place, making it easier for suppliers to access and use their data.

The first release of the portal is planned for early 2027 and is being developed around a shared framework of 24 measures. Ahead of launch, we have already started sharing the new data with some suppliers, and the feedback has been very positive.

Built with suppliers

The portal has been shaped by direct engagement with energy suppliers, including visits to understand what information they need and how it can best support their work.

Following this engagement, we shared a framework of 24 measures for feedback, helping establish a more consistent approach to reporting.

We haven’t waited for the portal to put this into practice. The first reports using these measures are already with some suppliers, and their feedback is helping shape what the portal will offer. This forms part of our wider work to improve the supplier experience.

What will the portal provide?

The portal will allow suppliers to select a reporting period and accessing information across four key areas:
•    Operational performance: How cases move through our processes, including our own performance.
•    Trends and demand: Understanding incoming cases and how volumes have changed over time.
•    Company and sector view: Context on performance across the wider sector and market. Comparisons are against the sector and whole market, not named suppliers.
•    Remedy analysis: Understanding the outcomes and remedies resulting from cases.

Bringing this information together will give suppliers a clearer picture of their performance and ours, helping them identify emerging trends and see how they compare with the wider sector.

This emphasis on consistent information also reflects our recent work on remedy classification, making outcomes easier to understand and analyse.

Supporting transparency and building trust

Edwyn van Rooyen, Chief Operating Officer at Trust Alliance Group, said:
“Making data more accessible is only part of the picture. We want suppliers to have clear, consistent information they can use to understand performance and how they compare with the wider sector. Sharing this insight with the sector and the regulator creates transparency and builds trust, and that improves things for everyone: suppliers, consumers and us. Working with suppliers to shape these measures has been an important part of that approach.”

The portal is designed to give suppliers consistent, comparable data when they need it, ready to feed into their own management information and reporting. It will also reduce the need for individual data requests and bespoke reports.

This reflects our wider commitment to using data and insight to improve services, support fairer outcomes and build trust and confidence between consumers and businesses.
