This documents sets out our findings from our review of water company progress on delivering open data and next steps. We published a discussion document, H2Open – Open data in the water industry: a case for change in October 2021. This set out the benefits of open data and how making more data open would help address some of the challenges the water sector faces from climate change, the environment, changing customer demands and protecting the most vulnerable. We set out that we wanted to see measurable progress in delivering open data in the following 12 months and would review progress in autumn 2022. We have assessed the progress that water companies have made since H2Open was published and this paper sets out our decisions on next steps.
