Why choose this course?
The CCN1 qualification is the foundation of domestic gas competence and is required for engineers carrying out gas work in domestic properties. Combining the CCN1 re-assessment with an appliance qualification provides an efficient way to renew competencies and ensure compliance with current legislation, industry standards, and Gas Safe Register requirements. The course enables engineers to refresh their knowledge of gas safety, installation requirements, testing procedures, combustion principles, ventilation, flues, and the safe operation of domestic gas appliances.

The NICEIC Core Domestic Gas Safety (CCN1) Re-Assessment + 1 Appliance course is designed for experienced gas engineers who need to renew their core gas safety qualification and one appliance category to maintain their Gas Safe registration and demonstrate ongoing competence.
This course is suitable for engineers who currently hold, or have recently held, the relevant gas qualifications and require reassessment in:
- CCN1 Core Domestic Gas Safety, plus
- One appliance category, such as CENWAT, CKR1, HTR1, DAH1 or MET1.
- Understand current gas safety legislation and industry standards.
- Refresh your knowledge of the Gas Safety (Installation and Use) Regulations.
- Review procedures for gas tightness testing and purging.
- Understand the requirements for combustion, ventilation, and flues.
- Learn how to identify unsafe situations and classify gas installations correctly.
- Refresh your understanding of gas controls, pipework, and installation standards.
- Review emergency procedures relating to gas escapes and unsafe appliances.
- Understand safe working practices when carrying out gas work.
- Learn how to interpret current guidance and technical standards.
- Maintain the core knowledge required to demonstrate ongoing gas competence.
Candidates who achieve the relevant appliance qualifications and meet the required criteria can apply for or maintain registration with the Gas Safe Register, enabling them to carry out gas work legally and safely within their area of competence.
Further career development opportunities may include specialist training in:
- Unvented Hot Water Systems
- Water Regulations
- Heat Pump Installation
The course is delivered through classroom-based theory sessions supported by technical discussions, worked examples, and review of current regulations and standards. Candidates will be assessed through a series of theory examinations, as required by NICEIC Certification. Successful completion of the assessments will enable candidates to renew their CCN1 core gas safety qualification.
