An AI policy for organisations is a written document that tells everyone how the organisation expects them to use artificial intelligence. It states where AI is approved, where it is banned, what may and may not go into a tool, when a human must review the output, and who to ask when the answer is not obvious. Its job is simple: let people get the benefit of AI while keeping the organisation on the right side of its legal, ethical and commercial duties.
The reason to write one is that AI is already in the building whether you have a policy or not. Staff are drafting emails, summarising documents and generating code with public tools, often with the best intentions and no idea where the lines are. The risk is rarely malice. It is a well-meaning colleague pasting a client contract into a free chatbot because nobody ever told them not to. A clear policy replaces guesswork with a standard, and in the UK it sits alongside established obligations, particularly data protection under UK GDPR, rather than replacing them.
The hard part is not writing the policy. It is writing one people will actually follow. That means it has to be short enough to read, concrete enough to picture, and honest about the useful cases as well as the forbidden ones. It has to name a person to ask and a safe way to report a mistake. The Institute of AI, the UK's professional body for AI, exists to define that standard and help organisations meet it. The sections below break a good policy into its parts and set out who owns what.
