These are the regional and subregional organisations which administer all aspects of the NHS in England.
Subregional integrated care boards (ICBs) replaced clinical commissioning groups (CCGs) in the NHS in England on 1st July 2022. There are currently 42 of them in England.
In 2025, the government announced the abolition of NHS England. As part of this change, ICBs are being merged to form ‘ICB clusters’. There will be 26, forming on either 1st April 2026, or 1st April 2027.
In this ‘new ICB world’, 35/42 are being merged into 19, and 7/42 are being left alone – making a total of 26.
But here they are (at present) divided up by the 7 NHS regions in England. Each ICB reports to one of the 7 regions.
As can be seen below, rather illogically, the current regions have very different numbers of ICBs (3-11).
In the ‘new ICB system’, there will be (more logically) 3-5 ICBs (or clusters) per region.
NHS East of England region (6 ICBs)
New NHS East Region: 3 ICBs
NHS London region (5 ICBs)
New NHS London Region: 4 ICBs
NHS Midlands region (11 ICBs)
New NHS Midlands Region: 5 ICBs
NHS North East and Yorkshire region (4 ICBs)
New NHS NE and Yorkshire Region: 4 ICBs (no change)
NHS North West region (3 ICBs)
New NHS NW Region: 3 ICBs (no change)
NHS South East region (6 ICBs)
New NHS SE Region: 4 ICBs
NHS South West region (7 ICBs)
New NHS SW Region: 3 ICBs
