ACS GAS Courses - Domestic Natural Gas Safety (CCN1)

CCN1, Domestic Gas Safety, is the core or initial qualification for engineers working on gas appliances and must be successfully completed before further specific gas appliance qualifications can be attempted, for example boilers, cookers, or heaters.

Who is this for?

  • For new entrants into the gas industry who have completed a recognised plumbing qualification or have completed the NICEIC Elementary Gas Course (Initial Assessment)
  • For existing plumbing and heating engineers renewing gas qualifications (Reassessment). CCN1 re-assessment can take place up to 6 months early without losing time

Entry Requirements

ACS Reassessment for renewal of gas qualifications

  • Candidates must produce original or previous certificates as demonstrable evidence prior to reassessment.
  • We would always suggest that training is undertaken prior to assessment, although not mandatory we do advise that training is often essential due to statutory or industry changes.

Or

ACS Initial assessment for new entrants joining the gas industry who have completed a recognised qualification and can meet the requirements of the guidance notes.

Theory and practical assessment.

  • For reassessment, allow up to 5 days.

Course Outcome

  • Successful completion of CCN1 will enable the holder of a certificate of competence to apply to the Gas Safe Register so that gas work can be undertaken legally within the scope of the Gas Safety in use Regulations. (GS(IU)R) Please note in addition, the operative must also hold the relevant appliance element relating to the work they wish to undertake.

    Successful completion of the core assessment (CCN1) provides a route to the following training modules:                       

    • CKR1 Cookers
