Express your interest in the Great UK WaterBlitz!
We will be running the next UK-wide data collection event between 18-21 September 2026. If you haven’t already done so, you can express your interest below and you’ll be the first to hear when registrations open up later this year.

Support the Great UK WaterBlitz
It costs £6 for each water testing kit used in the Great UK WaterBlitz and we rely on voluntary donations to support our work. Every donation means that we can test more waterbodies in more locations across the UK. Please donate to make the Great UK WaterBlitz as big as possible.
