What OneLondon does

OneLondon is a non-profit public-sector health data partnership established in 2018/2019 and supported by NHS England (London Region), bringing together London's five Integrated Care Systems (North West, North Central, North East, South East, and South West London), the London Ambulance Service, the Greater London Authority, and London's Academic Health Science Networks. The programme's purpose is to join up fragmented health and care information held across NHS trusts, primary care, community services, mental health trusts, social care, ambulance services, and care homes so that frontline clinicians can access a complete, real-time view of a patient at the point of care. It serves a London population base of approximately 7.5–9 million people, with over 100,000 health and care staff using its products monthly.

The core product portfolio comprises five interconnected digital services. The London Care Record is a shared care record built on Oracle Health's Health Information Exchange (HIE), providing a single secure view of patient information across organisational and geographic boundaries. The Universal Care Plan (UCP), launched July 2022 on OpenEHR technology supplied by Better Health, captures care preferences and support needs; it expanded beyond end-of-life care in March 2024 and became patient-editable via the NHS App in May 2026. The eMental Health Act programme uses Thalamos's eMHA system to digitise statutory Mental Health Act workflows at five London mental health trusts. The 999 Digital Transfer of Care automatically transmits patient data from London Ambulance Service crews to receiving Emergency Departments. The London Secure Data Environment provides a de-personalised research dataset for population health analysis and is supported by NHS England's £1 million pathfinder project funding across cancer, asthma, hypertension, and immunisation pathways.

OneLondon does not sell products or services commercially and generates no revenue. It is funded through NHS England (London Region), London's five ICSs, and partner public bodies, operating as a collaborative programme rather than a commercial entity. Its economic value is measured in staff time saved rather than revenue — independent evaluation by Queen's University Belfast (July 2025) estimates up to £4.6 million per month and up to £190 million cumulatively in clinician time savings. The programme is led by Luke Readman (Chief Officer and Director of Digital Transformation for NHS England London Region) and Jocelyn/Joss Palmer (Programme Director), supported by a small core team of approximately 13 staff. Adoption is driven through NHS governance structures and clinical engagement rather than commercial sales cycles.

Direct peers

• Rhapsody (Lyniate): Specialist healthcare interoperability vendor providing integration engines and EMPI/identity matching used by HIEs and shared care records. Competes in the underlying infrastructure layer OneLondon depends on.
• TPP: UK EPR vendor whose SystmOne platform is widely deployed in primary care and increasingly feeds shared care records. Competes for the data layer OneLondon aggregates, particularly in London primary care.
• Orion Health: Operates the Amadeus HIE platform, used by shared care record programmes including some UK regions. Competes in the same health information exchange space as OneLondon's London Care Record.
• Graphnet Health: UK-based vendor of the CareCentric shared care record, deployed in multiple English regions (e.g., Frimley, Berkshire, Buckinghamshire). The closest UK-based competitor delivering population-level shared records across NHS organisations.
• Health Catalyst: Healthcare data and analytics platform serving providers and health systems, with overlapping capability in linking fragmented clinical data for population health and research — comparable to the London Secure Data Environment.
• InterSystems: Provider of HealthShare, one of the leading commercial Health Information Exchange platforms globally. Directly comparable to OneLondon in delivering cross-organisational patient record sharing for health systems.

Broad incumbents

• NHS England: Operates the national NHS App and broader digital infrastructure, including commissioning OneLondon. Overlaps with OneLondon's patient-facing and national-policy dimensions at a much larger scale.
• Epic Systems: Provides Care Everywhere and other HIE-adjacent interoperability capabilities as part of its dominant hospital EHR footprint. Operates at much larger scale with overlapping cross-organisational record-sharing functionality.
• Oracle Health: Provides the HIE platform underpinning the London Care Record. Competes broadly in the EHR and HIE market (formerly Cerner) with capability overlap across OneLondon's data integration footprint.

Regional players

• Connected Care (Frimley Health and Care): Regional shared care record serving the Frimley ICS in the South East of England, built on Graphnet's CareCentric. Operates a comparable shared care record model in a different geography from OneLondon.
