Welsh Congregational churches or Independents stand in the Puritan tradition.

Now the Union works through six departments: finance, mission, ministry, education, churches, communication.

The Union is a free and voluntary body, its aims to help to make churches a fellowship that serve Jesus Christ.

The latest strategy is the Welsh Independents Development Programme.
