To drive transparency, innovation and a collaborative future
At Pennon, we believe data is more than information - it’s a powerful asset that can drive innovation, accountability, and environmental progress.
As the parent company of SES Water, our Open Data Strategy 2025 marks a bold step forward in transforming how we share and use data across the water sector.
Why Open Data Matters
The strategy outlines Pennon’s vision to make high-quality data accessible, reusable, and valuable to customers, researchers, regulators, and developers supporting transparency, innovation, and long-term sustainability.
Key highlights from the strategy include:
- Alignment with the Stream initiative, the sector-wide open data platform
- Publishing datasets on storm overflows, drinking water quality and many more
- Adoption of the FAIROE+P principles to ensure ethical, secure, and permissioned data sharing
- Commitment to upskilling teams and improving internal data maturity
- A roadmap to release new datasets and strengthen user feedback mechanisms.
At Pennon, we view open data not just as a technical requirement, but as a commitment to responsible innovation and public service. We invite researchers, developers, and communities to explore and use our data - and help us shape a better, more resilient future. The strategy aligns with Ofwat’s push for open data to enable better public services and drive environmental innovation.
