NABIS plays a crucial part in UK policing as part of the NPCC's portfolio, and is funded by the police forces of England, Wales and Scotland as well as partner law enforcement agencies:

• British Transport Police (BTP)
• Ministry of Defence Police (MODP)
• MI5
• National Crime Agency (NCA)
• UK Border Force (BF)
• Police Service of Northern Ireland (PSNI)

NABIS is an independent national policing organisation but hosted by West Midlands Police (WMP) for financial and legal purposes.
