This will mainly be to look through your CV (you may have an engineering or a manufacturing background for example - or maybe a HNC/HND) and contain a professional discussion where we will determine if you would be able to be successfull with the training and assessments. Prior training (if absent) such as Wiring Regulations may be recommended.
