The National Police Dynamic Purchasing System for Language Services

Welcome to the webpage for police language services. This page provides information relating to the use of interpreters for police assignments as well as contact details for those managing the services.

We live in a multi-cultural society and many people who do not speak fluent English come into contact with police officers and staff. They may be witnesses, victims, suspects or they may just need advice from their police service. In order for the police to effectively communicate with those who speak limited, or no English, they engage interpreters and translators to assist them. The same is true for those who require some form of non-spoken interpreter.

Police Use of Interpreters and Translators

The interpreters used by police forces across the UK are usually engaged through a Language Service Provider (LSP) via a formal contract.

Those deployed to police assignments must hold a Diploma in Public Service Interpreting (DPSI) with the law element, or a diploma in Police Interpreting (DPI). They must hold Non-Police Personnel Vetting at Level 3 (NPPV3) and they must have completed a number of hours experience in public service interpreting before undertaking police assignments. There are separate requirements for non-spoken interpreters.

There are always exceptions for when interpreters are urgently required, and none with the correct requirements are available. In this instance, the use of the interpreter must be risk assessed and approved by an officer of the rank of at least Inspector.

The National Police Chiefs Council has recommended a system of approving interpreters and translators that ensures every interpreter and translator holds the required qualifications, vetting and experience to undertake police assignments. Police Approved Interpreters and Translators (PAIT) are authorised by Leicestershire Police on behalf of all police forces in England and Wales.

Guidance for Police on use of Interpreters and translators

The College of Policing has issued guidance for police officers on the use of interpreters and translators, as well as guidance on briefing them.

This guidance is of interest to interpreters and translators and so is available for download from the College of Policing website:
