CCN1, Domestic Gas Safety, is the core qualification and is normally a pre-requisite to have before attaining other additional qualifications. There are some exceptions to this, but generally most candidates must complete CCN1, or already be in possession of this qualification before adding others. 

As you can see CCN1 contains several modules and 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 already hold. You must also allow time to undertake and successfully pass the associated theory and practical assessments associated with CCN1. These can also take a day or more to complete, again dependant upon the time you as an individual might need.
