Every weekend across the UK there are thousands of young people involved in Sea Cadet activities – learning new skills that will give them a head start in life. In fact, we work with 14,000 Sea Cadets aged between 10 and 18 – and are the UK’s largest maritime youth charity, with a history dating back to 1856.

"My son enjoys Sea Cadets so much that it has inspired me to become a volunteer."


Across the UK we have 9,000 dedicated volunteers who donate on average 200 hours a year each to supporting Sea Cadets,  that’s an incredible 1,800,000 hours every year! Which has a value of about £11 million. That is an amazing and humbling endorsement of what we do.

Could you be one of them?

We need your help – we need volunteers who are happy to roll up their sleeves, get involved and make a huge positive difference to the lives of the young people we work with.

We have lots of roles to match your skills and we offer training to help you gain more. You can speak to your local unit to find out how you can get involved.

How you can help



You'll be helping cadets in a range of activities and learning new skills yourself! We have a mix of uniformed and non uniformed instructors and follow a rank structure aligned to the Royal Navy and the Royal Marines.

Unit assistants

Be the backbone of your unit helping out in lots of ways from minibus driver to painter and decorator.

Unit Management Team (UMT)

Each unit has a UMT – unit trustees. So we need: Company Secretary, Chair and Treasurer. You'll be working as a team to fundraise and manage the unit.


Sea Cadets is open to all and embraces all faiths.  Working alongside young people and volunteers, our chaplains offer support to cadets and volunteers as they embrace new challenges. Throughout the Sea Cadets, chaplains appointed from clergy, lay readers and others with an authorised ministry work with units to provide moral and pastoral support.
