The u3a movement

u3a empowers people in later life to live healthier, more connected, and purposeful lives. Through its peer-led, volunteer driven model, u3a fosters lifelong learning, social connection, and active contribution, creating a vibrant community of shared curiosity and purpose.

We're one of the largest membership organisations in the UK with over 430,000 active members in over 1,000 u3as. Membership is open to everyone who has stepped away from full-time work; from employment, caring for others or raising a family.

Everything at u3a is powered by volunteers. As a volunteer movement, we all take it in turns to share our skills and knowledge with each other. This is learning with a difference. There are no teachers and students, no classes and no exams. We offer interest groups and activities; it is all done just for fun with lots of laughter along the way.

The Third Age Trust

The Third Age Trust is the national charity that supports the 1,000+ u3as in the UK. The work of the Trust is to promote, support and strengthen the u3a movement.

From the very beginning, the founders saw a need for a national body and in 1983 the Third Age Trust was formed.

In 2026 we developed a new strategy for the work of the Third Age Trust, providing a framework for its role in supporting u3as and promoting and raising awareness of the u3a movement.
