The NIHR is a complex, devolved organisation and can be confusing to those who aren't familiar with its intricacies.
Here you can find more information on what each part of the local NIHR does, and who it's designed to help.
It is worth being aware that there is some overlap between the different parts at each stage of the research process.
For example, the Research Design Service and Bristol Trials Centre both offer support for grant applications. The different parts also collaborate and work together.
The local NIHR can be divided into two functions: enabling research and conducting research.
