Is the NHS sharing your data? What you need to know

June 18, 2021

Learn more about how the NHS will share your GP data from 1 September 2021, and decide if you want to opt out.

What is changing?

From December 2021, NHS Digital will start collecting patient data from GP medical records in England about any living patient, including children, and any data about patients who died after the collection started.

This is called the General Practice Data for Planning and Research data collection, and NHS Digital says it will be used to help the NHS improve health and care services by allowing it to plan better, prevent the spread of infectious diseases, help with research and monitor the long-term safety and effectiveness of care.

NHS Digital is the NHS provider for data and IT systems for the NHS in England.

What will be collected?

NHS Digital will collect information on diagnoses, symptoms, test results, medications, information about physical, mental and sexual health, a person’s sex, ethnicity, sexual orientation and which staff have treated them.

This will include most of the historic data from each patient’s record.

The data collection won’t include people’s names or where they live. Of course, that’s not the only information that can identify someone. Other details, like NHS numbers, postcodes and dates of birth, which can identify people, will go through a process called pseudonymisation, which means codes will be generated to replace these details. NHS Digital says this means that no one will be able to directly identify you in the data, without also having access to the key that links each patient to their code.

NHS Digital says the keys to convert these codes back into data that could identify you, but won’t do that “unless in the circumstances of any specific request it is necessary for it to be provided in an identifiable form”.

NHS Digital says they’ll only do that in certain cases when there is a valid legal reason, for example, if you consent to participate in a clinical trial, or where the data was needed by a health professional to provide you care.


Is this data being sold?

The NHS Digital website says: “We are not going to sell your data”. But there is a price list on the organisation’s website listing charges for its Data Access Request Service.

On this page, NHS Digital says “We do not charge for data but we do apply charges to cover the cost of processing and delivering our service.”

Any organisations that want to pay to access this data need to convince the NHS Digital Data Access Request Service that they have a legal basis to use the data and will do so safely, securely and appropriately. Requests are also subject to scrutiny by the Independent Group Advising on the Release of Data.


NHS Digital publishes information on what data it releases and to whom every month. Many recipients are organisations like the Office for National Statistics, local authorities, government departments like the Department of Health and Social Care and research organisations like universities and charities, but they can also include companies that get approved.

NHS Digital says: “Any data that NHS Digital collects will only be used for health and care purposes. It is never shared with marketing or insurance companies.”


What do I need to do?

If you’re happy with your confidential patient information being used for research and planning you do not need to do anything.

You can stop your confidential patient information being used for research and planning by opting out either from it being shared with NHS Digital or by opting out from NHS Digital sharing your data.

If you do not want your patient data shared with NHS Digital, you can return this form to your GP practice. This is called a Type 1 Opt-out with your GP practice. You do this at any time and you can change your mind at any time and withdraw a Type 1 Opt-out.
