Before a candidate can be allowed to sit for the core ACS assessments, they need to provide evidence of completing a certified training programme such as the Gastec Managed Learning Programme. After the Managed learning programme is complete, sufficient proof of onsite working experience that is supervised by an accredited and Gas Safe Registered engineer is required to populate a portfolio. With the portfolio complete you will be awarded an Initial Gas Qualification (IGQ) which will allow you to undertake ACS assessment.

Looking for a re-assessment? With CCN1 re-assessment, completion of the ACS re-assessment must be within the last six months before the stated expiry date on the certification. If you have lapsed your CCN1 qualification over 12 months you will need to undertake an initial ACS CCN1 assessment to get you on your feet again.

• REGT1 – Domestic medium pressure meter regulators
• CPA1 – Combustion performance
• CMDDA – C0/C02 Atmosphere and appliance testingcor
