Domestic Gas Safety CCN1 and Appliances Reassessment
This reassessment is for experienced gas installers who are looking to renew their Core Domestic Gas Safety (CCN1) certification.
To register as a Gas Safe Registered domestic gas installer, you must hold the Domestic Gas Safety CCN1 Course and Appliances certification. You are required to undergo reassessment every five years.
Appliances covered in this reassessment are central heating and hot water, cookers and space heaters.
Candidates can be reassessed in separate modules if they do not require reassessment in all appliances.
The initial Core Domestic Gas Safety (CCN1) Course and Appliances course includes training and assessment in the following areas:
CCN1 – Core Domestic Gas Safety, including CPA1 (Combustion Performance Analysis)
CENWAT – Central Heating Boilers & Water Heaters
CKR1 – Cookers
HTR1 – Space Heaters (including Gas Fires and Wall Heaters)
The price of this package will be reduced for those candidates that don’t require assessment in certain appliance modules.
Impartial Examinations are undertaken under the control of UK Certification and this is separate from any Training Activity.
The CCN1 re-assessment course must be completed no more than 12 months after the expiry of the installer’s existing qualification. If the re-assessment is not completed by this date the candidate will be required to undertake the Domestic Gas Safety Course and Appliances (Initial) course.
CCN1 re-assessment can also be completed up to six months prior to the expiry date.
