TPCP1 is the qualification for strength testing, tightness testing and purging of industrial installations, not exceeding 16bar pressure. TPCP1A is the qualification for strength testing, tightness testing and purging of low pressure installations, not exceeding 1m3.  In summary, TPCP1 + 1A covers the following high level areas of learning and competence:

  • Strength Testing
  • Tightness testing
  • Direct purging
  • Gas Safety Regulations
  • Emergency Actions
  • Re-establishing gas supplies
  • Relevant unsafe situations


As you can see TPCP1 + 1A contains several modules and therefore training takes about three days to complete, actual time dependent upon whether this is the first time you’ve completed this training or if it is a refresher course to renew your qualifications. You must also allow time to undertake and successfully pass the associated TCPC1 + 1A theory and practical assessments. These generally take about two days to complete, again dependent upon the time you as an individual need to complete them.
