TWI CL Banned List

These are the details of individuals who have been subjected to bans from TWI Certification Ltd’s (TWI Cert's) Management Committees for breaches of our code of conduct, for example, by falsifying a certificate, breaking examination rules, or for professional misconduct. Where a breach includes the falsification of a certificate, the type of certificate and the certificate number used have been included. The extent of the ban is dependant on the extent of the breach, but it should be noted that as of 2020 the Management Committees of TWI Cert have taken a zero tolerance policy on the falsification of certificates, and individuals who have been found guilty of this are permanently banned from sitting a CSWIP examination or holding a CSWIP certificate. 

Please note, in the cases of falsified certificates, it is possible that the details given below may have been taken from the valid certificate of another certificate holder. As such, certificates that have the same details (name and/or certificate number) may be valid, but have unfortunately been used by others in the creation of a false certificate.

The below is not an exhaustive list. There are many individuals who falsely claim to hold a CSWIP or BGAS-CSWIP certificate and are never brought to the attention of TWI Cert. Any individual claiming to hold a CSWIP certificate should have the veracity of their claim checked using the (free to use) CSWIP verification service. If a certificate cannot be verified, an email should be sent to verification@twicertification.co.uk for further investigation and information.
