The LCL Awards CCN1 course is essential for aspiring and practising gas engineers wanting to certify in general domestic natural gas safety and appliance work. Designed to meet UK gas safety regulations and Gas Safe Register requirements, this qualification covers fundamental aspects of gas safety, tightness testing, purging, and combustion analysis—vital for working safely and legally with domestic natural gas appliances.
If you already hold the CCN1 qualification, you can opt for our refresher or reassessment programmes to maintain your certification and be fully up to date. These come highly recommended to remain compliant within the five-year validity period.
This course provides a solid foundation for working on domestic gas installations—including boilers, cookers, meters, and fires—by emphasising safety, legislation, and technical competence. Holding CCN1 is legally required for Gas Safe registration and greatly enhances your professional credibility.
Our training delivers the theory and practical skills you need, backed by expert instruction and hands on assessment. We ensure you’re well prepared to progress to appliance modules or broader gas engineering roles. Reassessment options offer a streamlined way to renew your certification if needed.
