He has previously served as chief executive of Leeds Teaching Hospitals NHS Trust, chief executive at Tameside and Glossop Primary Care Trust, chief executive at Blackpool, Fylde and Wyre Hospitals, and chief executive at University Hospital of South Manchester NHS Foundation Trust.
In addition, he was a non-executive director at the Department of Health and Social Care from November 2021 to November 2022.
Sir Julian said: ‘It is vitally important for NHS trusts, foundation trusts and the wider health and care sector to have effective regulation to support improvement and safe care for patients. This move will give me an opportunity to really focus on that goal.'
He added: ‘I will work with colleagues in the executive teams at NHS Providers and at CQC to make the transition as smooth and seamless as possible.'
The precise timing of the move and interim arrangements at NHS Providers ahead of the appointment of a new chief executive will be confirmed in due course.
Chair of NHS Providers, Sir Ron Kerr, said: ‘I would like to thank Julian for the great leadership and commitment he has brought to his role at NHS Providers. His insight and understanding of the provider sector have enabled us to go from strength to strength, supporting members through unprecedented challenges.
‘Julian has also forged a strong, productive relationship with colleagues across the staff team who have appreciated his expertise, integrity and his kindness.'
In response, Care England welcomed the appointment, but warned of the changes that lie ahead.
Chief executive Professor Martin Green said: ‘Inheriting an organisation that is not just in need of structural overhaul but one whose ability to rebuild trust within the sector has been seriously compromised, comes as no small task; but it is one that, if executed properly, could be incredibly powerful and rewarding for everyone who relies on adult social care.
‘Sir Julian has the opportunity to create lasting change, but this can only happen if the entire CQC listens to the voices of care providers and commits to delivering measurable improvements. We remain ready to support the CQC in achieving this, but real action and accountability must follow.'
