1 July 2022

The Health and Care Bill, that passed through Parliament in 2022, set out plans to put Integrated Care Systems (ICSs) on a statutory footing, empowering them to better join up health and care services, improve population health and reduce health inequalities.

Each ICS is led by an NHS Integrated Care Board (ICB), an organisation with responsibility for NHS functions and budgets, and an Integrated Care Partnership (ICP), a statutory committee bringing together all system partners to produce a health and care strategy. When ICBs were legally established, clinical commissioning groups (CCGs) were abolished.

It was originally expected that these changes would come in to effect in April 2022. However, this target date was changed to 01 July 2022 to allow more time for the parliamentary stages to take place and to enable organisations to manage their more immediate pandemic response priorities. See the NHS 2022/23 priorities and operational planning guidance for more information.

When ICBs were established, all CCG websites were closed down and the information was stored on The National Archives website.  You can access the archived websites for the former six clinical commissioning groups here:
