Human Tissue Authority

The regulator for human tissue and organs



The day-to-day running of the organisation and our licensing and inspection operations are managed by a small core team, which is split into four directorates and led by a Chief Executive.

Chief Executive

Allan Marriott-Smith became Chief Executive of the HTA in July 2015. Allan joined the HTA in May 2009, most recently working as Director of Strategy and Quality where he had corporate responsibility for the strategic and business planning process, quality improvement and the regulation of living donation. Prior to that Allan had worked for a number of years as a government statistician at the UK Statistics Authority.
As the Chief Executive of the HTA, Allan is the Accounting Officer and is responsible for implementing the strategic plan of the organisation. This involves improving the efficiency and effectiveness of regulation, ensuring that the HTA has appropriate and productive relationships with its stakeholders, and leading and managing the skilled and dedicated workforce at the HTA. Allan is also responsible for ensuring that the HTA is governed effectively and provides good value for money.

Director of Regulatory Development
