Interpreter Registration

Thank you for your interest in becoming a freelance interpreter. WITS is a partnership between more than 30 public sector bodies throughout Wales. As a freelance interpreter you will have the opportunity to work in a variety of different environments including Local Authorities, Health and Police Forces.

WITS welcomes new register requests from linguistics of any language and are able to support you through the registration process and required vetting standards.

Registration requests are considered based on several criteria, including, but not limited to:

  • Languages spoken
  • Current location
  • Previous experience
  • Relevant qualifications
  • Your availability
  • Vetting

During the registration process, only state languages you have a firm command of and can interpreter to a professional standard.

We would always assume applicants have a firm command of the English language to the standard of professional interpreting, as this will always be either the target or source language of any assignment.

All interpreters who request to register their services with WITS, do so on the basis they are freelance interpreters, are self-employed and are responsible to declare any earnings with the appropriate authorities, i.e. HMRC through self-assessments. WITS do not make any dedications for Income Tax or National Insurance contributions.

WITS cannot guarantee a set number of assignment or number of hours for any period. The number of assignments depends on several factors, for example but not limited to:

  • Demand
  • Your availability
  • Criteria of assignment

You will be contacted when your services are required.

Through this registration you will be registering with Matrix CDL Ltd, our agency workers administrator, who arranges payment / remittance for completed assignments for all our freelance interpreters and security vetting up to Enhanced DBS.

If you wish to register as a self-employed freelance interpreter, please complete the registration form below.

Best wishes,
The WITS team.

    General Information

    Vetting process

    Every interpreter on the WITS register has to be vetted either to an Enhanced DBS or an NPPV Level 3 standard (National Police Personnel Vetting Level 3). The Enhanced DBS level of clearance permits our interpreters to be appointed to Health Board and Local Authority work. The NPPV Level 3 clearance is vetted at a higher level which permits interpreters to be appointed criminal justice sector work. We will carry out the necessary vetting on acceptance of your application. We will send you more information about this once your application has been accepted.
