Information for police

Our guidance for police officers, staff, professional standards departments, and other policing organisations all in one place.

When handled appropriately, complaints can lead to better police practice and services. This benefits local communities and police forces. 

On this page you will find all the tools and guidance you need about the complaints system. Information is split into general guidance for all police officers and staff, and information that is primarily for professional standards departments.

Learning the Lessons

Our Learning the Lessons magazine helps to improve police policy and practice. It supports the police service to learn lessons from investigations into complaints and conduct matters.


We work with our external policing stakeholders to identify issues, improvement action and effective, shareable practice.


Focus gives police force professional standards departments practical guidance on dealing with complaints, conduct matters, and death or serious injury cases. It supports police complaint handling and improves standards.


Each year our investigators carry out hundreds of independent investigations into the most serious and sensitive incidents involving the police.
