The Great British Beach Clean

The Great British Beach Clean is a week-long citizen science event taking place between Friday 18th - Sunday 27th September 2026, where hundreds of beach cleans take place up and down the UK.

What is the Great British Beach Clean?

With the help of our supporters, we're working to clean up beaches all around the UK and Northern Ireland. Every year in September, we run our flagship Great British Beach Clean event to encourage people to get involved.

Litter data collected on beach cleans drives our conservation work, helps us to campaign for change, and also feeds into the International Coastal Clean-up (ICC).

Our data has been used to make a positive impact on our ocean - including the introduction of the plastic bag charge, banning microplastics in personal care products, better wet wipe labelling, and supporting a tax on single-use plastic items.

But there is still so much to do to stop the litter plaguing our beaches.

How to get involved

It's easy to get involved. Simply find a beach clean near you or register as a volunteer and organise your own. We've got lots of guides and resources available to help you get set up.

Beach cleans are fun for all the family (including dogs!), and the data collected helps us to campaign for positive change for the ocean.
