What our Electrical courses offer

Electrical is the installation, fabrication and assembly of equipment requiring or made up of electrical input, such as premises wiring, manufactured wiring systems, raceways and more.

Our courses offer High and Low Voltage jointing training, enabling jointers and jointers' mates to gain the knowledge and skills they need to work on:

DNO networks that distribute electricity at scale from the transmission grid
IDNO (private) networks that distribute to smaller localised areas from DNOs or the transmission itself
DNOs or the transmission itself overall maintenance and connection line fault repairs on both networks

We give operators to senior managers the tools and expertise to conduct their work safely, and our courses qualify workers with proof of training certificates upon completion.
