Course description

ACS Reassessment is for those Category 1 candidates who are experienced gas fitters with existing gas knowledge and skills. These are operatives looking to renew certificates which have expired (less than 12 months) or are due to expire. Additionally, Category 1 candidates are also those of you looking to add appliances and expand your scope of work.

What Youll Learn

This is a period of learning and assessment for individuals to renew their ACS certificates. Your training/revision period will be easier to determine if you can advise if you have been regularly undertaking the areas of gas work covered by your existing certification.

Reassessment ACS is a mixture of assessing both your practical skills and theory knowledge. You can undertake assessment for:

CCN 1/CPA1: Core Gas Safety

CENWAT 1: Central Heating Boilers

CPA 1: Combustion Performance Analysis

CKR 1: Domestic Cookers

HTR 1: Gas Fires and Wall Heaters

MET 1: Meters

DAH 1: Warm Air Heating Appliances

How Youll Learn
