Providing assurance to industry of the competence and capability of individuals and organisations is of paramount importance to TWI Certification Ltd (TWI CL). As such, we provide a service by which customers, employers and third party organisations can check the validity of a certificate or statement that an individual or organisation is certified by TWI CL.

CSWIP and BGAS-CSWIP certificate holders can input an individual’s customer or certificate number with their date of birth on the CSWIP website to verify the type, date of expiry and scope of an individual’s certification.

Those who hold a training organisation or company certification, are entered into our Registers. To confirm a company or training organisation certification status, input their name into the search bar, and each record will have details of the certificate(s) and schedule(s) available for review.

Companies who hold WFCS certification (for non-rail welding) are entered into the EWF/IIW Certified Companies Database, which can be accessed here:
