ACS Training - Revision & CCN1 Test Questions

​Whether you have just started your training at college, are considering becoming a gas engineer or simply applying to sit your 5 yearly re-assessments, the ACS competence assessments can be very challenging.

Your CCN1 and Appliance Certificates are needed to work legally on gas or apply for your gas licence to join the gas register. Passing the ACS gas assessments first time is very important because failing them can affect your ability to work in the industry, and make a large hole in your wallet.
