Open data means making data freely available to everyone to access, use and share, unless there’s a really strong justification for not doing that. Data and the people, processes and technology that support it are important assets – like water pipes and treatment works.
Data is essential for developing insight, making informed decisions and improving services. The use of open data could transform water and wastewater service delivery by increasing transparency, increasing efficiency, enhancing customer experience, and stimulating innovation.

Last year we reflected on what is already happening within the industry to open up data, the untapped opportunities and challenges that need to be overcome. Below you can find out more about H2Open – Open data in the water industry: a case for change discussion paper and open data resources already available across the sector.
We are now carrying out a review of water companies’ progress on open data. The review will be conducted over the next three months. We will use the findings from the review to inform our decisions on next steps – to be taken early in the new year. We would welcome your views on open data and you can find out more how to join the H2Open discussion below.
Last October we published ‘H2Open – Open data in the water industry: a case for change discussion paper’.
- The paper set out our initial views on how open data can enable water companies to create value for water customers, communities and the environment.
- We stated that we are confident that the industry is well placed to deliver open data and has the capability, expertise, and incentives to do so.
- We acknowledged that the water industry is at the start of this journey and companies would need to make this more of a priority and work together to unlock the best outcomes from open data.
- We said that we would review progress of water companies in autumn 2022. And we have now started this review.
We know that there is some good work happening – and there is much more that could be done. The scrutiny of the sector over the summer and the potential to improve company performance for customers and the environment reinforces the case for open data in water.
We are keen to understand the progress that companies have made in the last 12 months, individually and collectively, in making practical steps on opening up more data. We want to hear your views on this and we set out below how you can contribute
We have engaged PwC to help us assess water company progress on open data, and along with wider stakeholder views, we will be taking this into account when we make decisions in the new year on our next steps.
We want to ensure that the industry harnesses the full potential of open data.
Many of you have already contributed to this discussion and we welcome your continued contribution. We would welcome your views on:
- What data should companies make available openly?
- What would be the benefits?
- What progress you think companies have made on open data?
- What challenges and opportunities do you see in opening up more data?

On 13 October 2021 we published our first discussion paper about open data in the water industry.
This paper – H2Open – Open data in the water industry: a case for change discussion paper (also available in Welsh, Mae’r cyhoeddiad hwn hefyd ar gael yn Gymraeg) sets out the case for how open data can enable water companies to create value for water customers, communities and the environment. We have also published H2Open – Open data in the water industry: a case for change – Case study appendix.
We intended this paper to supercharge a public discussion about the benefits of open data and how it could be used to help address some of the challenges the water sector faces. We know that there are a wide range of stakeholders with an interest in open data and achieving change will need the passion, energy, support and skills of many people.
In this section you will find a list of open data resources already available in the sector. If any links are broken please contact the organisation who owns the link. Ofwat is not responsible and cannot assist with any technical issues on the links below.
