Once you have your CCN1 Gas Safety certificate you can also take these gas modules:

    • CKR1 Cookers
    • HTR1 Heaters
    • CENWAT Central heating and water heaters
    • MET1 Meters
    • LAU1 Laundry
    • LEI1 Natural gas leisure and miscellaneous appliances

 You could also take CODNC01 and LPG assessment. Some of our CCN1 candidates also cross train to work as oil appliance installers.

Candidates undertaking assessment for the first time will be required to produce either of the following:

  • NVQ or City & Guilds craft certificate in a trade associated with gas work, or plumbing, or
  • a Gas Diploma also known as the Managed Learning Programme which can also be undertaken at Kiwa

Renewal candidates will be asked to provide evidence prior to taking ACS assessments that they possess a gas fitting qualification or certificate(s) of gas safety competence issued either within or outside of the UK.

Existing CCN1 domestic gas engineers are reassessed every 5 years to make sure their skills are up to date and are then issued with a new certificate.

CCN1 training and assessment takes up to 5 days.

You can book your reassessment 6 months before your qualification expires.

You must be reassessed within 12 months of your certificate expiring to maintain your gas safety competence.
