  • CKR1 – Cookers
  • HTR1 – Space Heaters (Including Gas Fires And Wall Heaters)

This course is made up of both theory-based sessions in the classroom and practical sessions in our workshop, taught by our exceptional and experienced trainers. By the end of the course you will not only be up to date with the latest changes in the industry, but also confident and competent in Core Domestic Gas Safety and the additional appliances. We will make sure you are well prepared and setup for success for your assessment. All course materials required will be handed out to you in the beginning of the course.
