COCN1, Commercial Natural Gas, is the core qualification and is normally a pre-requisite to have before attaining other additional commercial qualifications. There are some exceptions to this, but generally most candidates must complete COCN1, or already be in possession of this qualification before adding commercial qualifications. In broad terms COCN1 covers the following:

  • Gas Safety Regulations
  • Emergency Actions
  • Combustion
  • Ventilation
  • Flueing
  • Gas pipework
  • Strength testing
  • Let-by & tightness testing
  • Purging
  • Re-establishing gas supplies
  • Pressure regulators
  • Gas rates & pressures
  • Gas controls
  • Emergency valves
  • Unsafe situations

As you can see COCN1 covers several areas, therefore training takes a number of days to complete, actual time dependant upon whether this is the first time you’ve completed this training or if it is a refresher course to renew qualifications. You must also allow time to undertake and successfully pass the associated COCN1 theory and practical assessments. 

A bit of text here to explain as to what the boxes mean. e.g. you have to have all of the qualifications in any one of the boxes to be able to do this course.

There are no requirements.
