Thank you for taking part in the Mayor of London’s Clean & Healthy Waterways Schools Challenge 2026.

Please complete this form to submit your child’s artwork inspired by this year’s theme: The River of Life.

Please note, due to technical limitations of the form, we have had to create an extension link to enable more artwork entries. You can upload 20 entries in this form, and then will have the option to upload more via another link. We're sorry for any inconvenience, and we hope this workaround is straightforward to use.

Before submitting, please ensure:
• the artwork has been created on the official template
• the file is uploaded as a JPEG or PNG
• the file size is no larger than 16MB
• you have permission from the child’s parent or guardian to submit the artwork

Submission deadline: 26th June 2026
