The Core Domestic Natural Gas Safety (CCN1) and appliance reassessment course is a necessary requirement of the ACS (Accredited Certification Scheme). The re-assessment training allows you to renew your qualifications in order to maintain your Gas Safe Register membership. The CPA1 (The Combustion performance analysis module) is now an integral part of the CCN1 Core module.

Entry requirement

  • You must be due for renewal or have had your qualification expired within the last 12 months.

Includes the following modules/assessments

  • CCN1: Core Domestic Natural Gas Safety (now including CPA1)
  • CENWAT: Central heating boilers/hot water heaters
  • CKR1: Cookers
  • HTR1: Gas fires

Please Note:

You must bring with all of your original and current ACS Certificates in order to take the assessments.

Training is not mandatory nor a pre requisite to the assessment. However most installers find that they benefit from undertaking refresher training prior to assessment.
