Course Overview

The CCN1 & CENWAT course at Vulcana Training is ideal for domestic gas engineers looking to gain or renew their qualifications in core gas safety and central heating appliances. This combined ACS package ensures you meet the industry requirements to work on boilers and water heaters as well as carry out essential gas safety work.

CCN1 is the mandatory foundation module for all domestic gas work, while CENWAT is a required appliance assessment for engineers working with central heating systems and unvented water heaters.

Successful completion of both modules results in renewed or initial ACS certification, allowing Gas Safe registration and legal work on domestic gas systems.

CCN1 – Core Domestic Gas Safety
Covers key elements of gas safety, including:

  • Legislation and regulations

  • Tightness testing and purging
