The ACS Gas Re-assessment course is perfect for keeping engineers up to date with their gas certifications and the most recent gas safety legislation. Practicing gas engineers must renew their existing qualifications (by law) every 5 years in order to keep up their membership with the Gas Safe register. To register as a domestic gas installer, you must hold Core Domestic Gas Safety (CCN1) plus certification for the appliances you intend to work on. Universal Skills Group provides an Ofsted Outstanding course for both self-employed engineers and company training programmes. The course is tailored to the engineer and the gas appliances they work with, or wish to work with moving forward.
