No matter where you live across the UK, you can help keep our seas clean. Most of the litter that ends up on our beaches or in the sea starts its journey in villages, towns and cities miles from the coast.

    Source to Sea Litter Survey event

    Get ready to be part of something big! This year, we're launching a nationwide Source to Sea Litter Survey event. From the 16th - 31st May, we have an ambitious goal to record at least one litter survey in each and every one of the UK’s 124 postcode zones - and we need your help to make it happen.

    Whether you’re out on a walk, at school, or rallying your community, taking part in a survey will help us create a snapshot of litter across the country. By tracking the litter you find locally, you’ll help us learn more about how inland litter travels from source to sea, strengthening the case for solutions like Deposit Return Schemes and cutting single-use items to support a circular economy.

    How to take part

    1. Download and print our Source to Sea litter survey form. We've also created a simplified recording form, with clear line drawings of each item, which are easy to print for larger groups.

    2. Head to your local park, street or river and record which litter items you spot there - keep a tally of how many you find. If you're taking part with younger children, you can tick the form instead.

    3. If it's safe to, and the litter is on public land, you can either take the rubbish home with you or arrange uplift of litter with the local council - remember to recycle it wherever possible

    4. Submit your litter data. If you prefer, you can email us a photo or scan of your form to beachwatch@mcsuk.org

    What is the Source to Sea litter survey?

    Every year, thousands of people head to the coast to take part in a beach clean and record what they find there. But if you don't live near the sea, you can still make a difference to the health of our ocean by recording the litter you see in your local area.

    80% of marine litter comes from land-based sources finding its way into streams, rivers or drains and ending up in the ocean, where it causes problems for ecosystems and sea life.

    As part of our inland litter cleans, we use the data you collect to track rubbish back to its source. Your survey results are then used to find solutions to ocean pollution and to campaign for measures to bring positive change.

    Taking part is simple and you can conduct a clean at any time of year. You can make a difference wherever you are in the UK.

    When you've finished your event, if would be great to have any feedback on any hazards to help us improve the safety of litter clean ups. Please complete the section on the form.

    Why your help matters

    All of the data you collect on the beach, on your street or in a local park helps us campaign for change to protect our ocean.

    Organiser forms

    Taking part or leading an inland clean might seem overwhelming, but it couldn't be simpler. Whether it's a 5 minute clean or 2 hours, a small playground or an entire football pitch, it works around you. Additionally, if you're leading a group, we've put together a handy guide to help you run a litter pick so you can make sure every knows what to do.

    Health and safety forms

    Before heading out to conduct your survey, check out our handy risk assessments to help you stay safe. In order to be covered by our insurance event organisers must make time for appropriate planning, risk assessment and minimisation prior to their event.
