Tickell has led the children’s charity for the past nine years and in 2008 was voted Most Admired Chief Executive at Third Sector’s Britain Most Admired Charities awards.
Tickell will replace Bruce Moore, who has been chief executive of Hanover for the past seven years and who will step down next month. Before joining Action for Children, Tickell spent 18 years working in the housing sector, which included roles as deputy director of Centrepoint and chief executive of Stonham Housing Association. No date has been set for when she will join Hanover.
Tickell is currently a board member of Guinness Partnership - a housing association - chair of the Help the Hospices' Commission into the Future of Hospice Care and chair of the Community, Voluntary and Local Services Honours Committee, which reviews honours nominations.
Jacob Tas, deputy chief executive of Action for Children, will run the charity until a full-time replacement is appointed.
Tickell said: "I am absolutely thrilled to be joining Hanover at this exciting time. Hanover is a leading provider of high-quality housing for older people, supported by an exceptional track record and senior management team. This puts it in a very strong position to respond to the challenges and opportunities facing providers of housing as the ageing population increases. It is a great privilege to have been selected to follow Bruce and I look forward to it very much."
John O’Brien, chair of trustees of Action for Children, said: "I’d like to pay tribute to Dame Clare Tickell, who has led Action for Children through some of the biggest changes and challenges in its history. Clare has grown the charity: we now support more than 250,000 children, young people, parents and carers through more than 650 projects. She has also ensured that we are a leading voice on behalf of children and young people around the UK and has been a driving force for our campaigning work."
