Gas Engineering apprenticeship

Gas engineering involves the safe installation, commission, decommission and the ongoing service and repair of gas appliances in either a domestic or non-domestic setting. Roles in gas engineering are physical in nature, and may involve lifting and moving of equipment, working at heights and working in confined spaces. All gas engineers must be registered on the Gas Safe® Register for each appliance in which they are competent to undertake work on. Those who work within Gas engineering must have the core requirements below and demonstrate the technical requirements in one setting - domestic or non-domestic. They must be registered on the Gas Safe® Register for four appliances.
