CCN1 (or a suitable changeover) is required for any operative wishing to work on domestic gas installations and appliances. In addition, the operative must also hold the relevant appliance element relating to the work they wish to undertake.

Learners outcomes:


For the initial assessment candidates must meet the entry requirements as published inThe Handbook for Learners and Centres

For re-assessment candidates must have held the element previously - if this has expired within 12 months of the assessment date the initial assessment must be undertaken.

The CCN1 core domestic gas safety certificate is regarded as an equivalent to a Level 3 QCF/RQF qualification in the gas utilisation sector (which is also aligned to ACS) and satisfies the same gas safety criteria leading to a certificate of competence recognised by the Gas Safe Register.
