Energy Technical Training Centre
We also have our very own Energy Technical Training Centre in our office in Dartford. The training centre has been created in order to address the growing skills shortage. The centre has been purpose built and contains various workstations, enabling trainees to experience every day scenarios which you can expect to experience on the job.
The courses range from Jointers Mate and Electrical Jointers right through to Voltage Systems and Site Manager. We also provide non-electrical courses such as Site Safety Training, First Aid and Fire Warden through to Safe Excavation of Buried Cables, Substation Freshers and working within Confined Spaces.
