The Heritage Alliance unites over 170 independent heritage organisations in England, acting as a powerful, effective and independent advocate for the movement. The Heritage Alliance is England's biggest coalition of heritage interests. It brings together the independent heritage organisations, from the National Trust, English Heritage, Canal & River Trust and Historic Houses Association, to more specialist bodies representing visitors, owners, volunteers, professional practitioners, funders and educationalists. Between them, over 6.3 million volunteers, trustees, members and staff demonstrate the strength and commitment of the independent heritage movement.
