The National Data Guardian advises on the use of confidential health and care data, supporting its safe, ethical, and trustworthy use for individual care and public benefit.

What the National Data Guardian does

The National Data Guardian (NDG) is an independent advisor to the government and the health and adult social care system in England.

They help ensure that confidential health and social care data is handled safely and used in ways that people expect and can trust.

The NDG is not a regulator with investigative powers. Instead, they provide advice and guidance that shapes data policy, practice and IT programmes, helping the system use data responsibly to support and improve people’s care, health service planning, and innovation and research.

The Department of Health and Social Care sponsors the role.

How the NDG works

Key work areas include:

Improving access to healthcare information

The NDG supports timely access to the right healthcare information for clinicians, healthcare providers and patients. This includes:

advising programmes that aim to improve access to information in support of people’s care

providing clarity on when data can be used for activities essential to providing care, without needing additional legal approvals

emphasising the importance of cyber-security and resilience, including continuity planning to maintain safe care during cyber-attacks or IT system failures

Developing strong guidance and policy

Clear data policy and guidance can give professionals confidence and reduce barriers for important uses of data. The NDG contributes to this by:
- publishing both statutory and informal guidance to address gaps or uncertainties in specific areas of data governance, and working with organisations such as the Information Commissioner’s Office and NHS England to strengthen their guidance
- resolving grey areas in data policy by identifying and addressing complex legal and ethical questions, to support safe and trusted data use
- providing advice and reviews of government and NHS data policies, practices, and programmes to help ensure compliance with legal and ethical standards
Advising on transparency and engagement to strengthen trust

Promoting transparency, accountability and public engagement is essential to maintaining public and professional confidence in the use of healthcare data. This work includes:
- advising healthcare data programmes on effective public engagement and transparent communication, to build trust and help avoid failures caused by low public or professional confidence
- supporting and commissioning research into public attitudes towards data use, helping the health and care system stay aligned with what matters most to people
Promoting the Caldicott Principles and supporting Caldicott Guardians

The NDG owns and maintains the Caldicott Principles (https://www.gov.uk/government/publications/the-caldicott-principles). These good practice guidelines were first established in 1997 and are widely used in health and social care to support responsible data handling.

The NDG also supports the UK Caldicott Guardian Council (https://www.ukcgc.uk), which helps Caldicott Guardians uphold these principles within their organisations.

What the National Data Guardian does not do

It is also important to understand what the NDG does not do, so you know where to direct your questions or concerns.

As the NDG is not a regulator with investigative powers, they cannot investigate individual complaints from the public.

Although the NDG does not investigate individual cases, they do monitor common data issues. Where patterns show national concerns, these inform policy and guidance.

Questions, concerns or complaints about how healthcare data has been used or handled should be directed to the appropriate organisation.
