The statutory arrangements began with 42 ICBs. CCGs were abolished.

UK NHS ICS maps and ICB boundaries
An Integrated Care System and its Integrated Care Board cover the same geographical area. Use the current April 2026 ICB boundaries to map England’s 36 ICS areas, then choose editable files, free individual maps or the online colouring tool.

Is an ICS the same as an ICB?
For drawing the boundary, yes. As organisations, they are different. NHS England confirms that an ICS and its ICB have the same geographical footprint. An ICS brings together the NHS, councils and other health and care partners; the ICB is the statutory NHS body within that system.
| Term | Role | Mapping implication |
|---|---|---|
| ICS Integrated Care System | The wider partnership working across a health and care area. | Use the corresponding ICB boundary for the same reference date. |
| ICB Integrated Care Board | The NHS body responsible for planning and commissioning most local NHS services. | The official ICB geography provides the system outline. |
| ICP Integrated Care Partnership | The joint committee that develops the area’s integrated care strategy. | It is a partnership structure, not an extra set of polygons in this map. |

Which ICS boundary date should you use?
ICB mergers and boundary changes reduced the total to 36. Those changes also changed the ICS footprints.
Match the map to the date of your figures. For current coverage, start with the April 2026 maps; retain an earlier map when comparing historical data.
ICS and ICB are England-specific terms. The wider UK bundle shows the relevant health-board or trust areas for the other UK nations, separately identified.

Questions about these maps
Can I use an ICB map to show ICS areas?
Yes, provided the boundary date matches your project. NHS England states that the ICS and ICB geography is the same.
Are ICSs called ICBs now?
The terms describe different things. An ICS is the wider health and care partnership; its ICB is the statutory NHS commissioning body. They share a boundary.
Do I need Sub-ICB boundaries?
Choose the detailed ICB bundle when you need smaller reporting areas within the system. Choose the national overview when the main ICB / ICS outlines are sufficient.
