ACS Gas Assessment (UK): CCN1 and Appliance Modules — Syllabus & notes
Exam overview
The Nationally Accredited Certification Scheme for Individual Gas Fitting Operatives (ACS) is how gas engineers in the UK prove their gas safety competence before they can be listed on the Gas Safe Register, the class of persons approved by HSE under regulation 3(3) of the Gas Safety (Installation and Use) Regulations 1998. Each type of work has a core assessment and appliance assessments: a domestic natural gas engineer working on boilers needs CCN1 (core domestic gas safety) and CENWAT (central heating boilers and water heaters), and adds modules such as CKR1 (cookers) or HTR1 (gas fires and wall heaters) for other appliances. The criteria, called the Matters of Gas Safety, are set by the industry Standard Setting Body managed by IGEM and assessed by UKAS-accredited certification bodies at ACS assessment centres, through practical performance criteria and knowledge and understanding. New entrants first complete industry-recognised training. Certificates must be renewed every five years, by ACS re-assessment or the Group Competency Scheme, and Gas Safe registration itself is renewed every year.
