CCN1 Core Gas Safety Reassessment (ACS)

The ACS CCN1 re-assessment is for existing gas professionals who already hold the ACS Core Gas Safety (CCN1) domestic qualification and relevant gas appliances that have not expired (no longer than 12 months) or are near to expiring (within 6 months). Candidtaes can undertake re-assessment up to 6 months in advance of expiring and have the relevant time added on to the new certificate expiry date.
