CESP1, Emergency Service Provider – Natural Gas, is the core qualification for ESPs and is normally a pre-requisite to have before attaining any further ESP qualifications. There are some exceptions to this. 

As you can see CESP1 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 CESP1. These can also take a day or more to complete, again dependant upon the time you as an individual might need.
