The renewal and recertification processes outlined here apply to NDT Inspectors, Operators and Interpreters.

All certificates should be renewed at the 5-year point and recertified at the 10-year point (subject to some exceptions listed below).

Five-year renewal

• Certificate holders must complete a renewal application request online 
  

• Once received by TWI Certification Ltd (TWI Cert), you will be contacted and sent the relevant renewal documentation and further guidance on the renewal process.

Certificate holders are required to submit with their renewal form:

• A verified work experience record covering at least 4 out of the 5 years that your certificate is valid

• A record of your continuing professional development (CPD), of at least 35 hours per year (can be recorded in your CSWIP/BGAS-CSWIP Log Book)

Renewals can be undertaken via Examination or Structured Credit for all Levels

• N.B., Only one application for Structured Credit can be received, failure to submit all documents and meet requirements with the initial submission will mean you must sit the examination – no additional submissions for the Structured Credit will be accepted or reviewed.  

Additions:

• Radiographic Inspectors must hold a current CSWIP Radiation Safety Certification, in addition to the above

PLEASE NOTE

Should there be any errors, omissions, or missing documentation within the initial application, you will be contacted by email. Therefore, please ensure that a valid and correct contact email address is provided on the application form.

Incomplete applications will incur an additional administrative fee, and late submissions of the application forms are subject to a late payment fee.
