Pan-London Data Sharing Agreements Project

Improving and tackling barriers to data sharing across London

Jump to: Introduction Collaborators Resources Project Timeline
Status: Live



Organisations across London share personal data daily to deliver their statutory obligations, prevent crime or harm, and improve the wellbeing of residents. There are many Data Sharing Agreements (DSAs) across London borough councils, the Metropolitan Police, health trusts, the Probation and London Ambulance Services, voluntary sector groups, and more. 

There is pressure on national or pan-London organisations who must agree to multiple DSAs for the same purposes, and there is a constraint that different organisations have different geographical boundaries. It is difficult for organisations to sign multiple agreements for the same subject/purpose, or to expect their staff to work under different DSAs depending on the location of the individual with whom they are working.

Since the fundamentals of sharing data for many public sector purposes are the same across local authorities and the police, it is preferable to have one agreement; to provide clarity to professionals and promote a shared understanding of when and how information should be shared.

 As it is one of LOTI’s key goals to tackle barriers to effective data sharing, this project will significantly contribute to that aim.

Get Involved


If you would like to engage with this project to develop a pan-London DSA or discuss data-sharing opportunities, please contact Victoria Blyth from the LOTI team. 

If you are a member of an organisation that is a party to an existing DSA then we recommend that you contact your organisation’s Data Protection Officer or Information Governance Team first.

 DSAs are hosted on the Information Sharing Gateway.
