For whom?

The training is for skilled employees, such as electricians and maintenance technicians, who carry out work on electrical installations. 

What does the law say?

As an employer, you are required to issue a certificate of competence for each employee who comes into contact with minor and major electrical works and installations. You, the employer, can use these certificates of competence to demonstrate that your employees are capable of and have sufficient knowledge in working on or near electrical installations.

A certificate of competence for working on electrical installations has two levels:  

  • BA4 Informed Person
    This certificate applies to employees who could possibly come into contact with electrical installations but do not carry out work on these installations themselves. This means they must only carry out non-electrical tasks, or minor alterations under the supervision of a competent employee.  
  • BA5 Competent Person
    This certificate applies to employees who personally work on or with electrical installations, or who supervise works carried out by informed persons (BA4). Examples of competent persons are engineers or technicians.  

As well as the training certificate for BA4 or BA5, it is also important that you – the employer – draw up a risk analysis for the electrical installation(s) in order to be able to issue a conclusive certificate of competence.

      Frequently Asked Questions

      Will I receive a valid BA4 certificate after taking the e-learning course 'Performing small electrical work safely for informed persons (BA4)'?

      Yes. The course is for people who occasionally carry out small electrical work where there is little risk. You learn to recognise risks and act appropriately at your own pace.

      You will receive a training certificate after passing a short test. Your employer will then draw up a 'BA4 Informed Person' certificate of competence.

      Can I take a BA5 course without having taken BA4 first?

      In principle, yes. However, we do not recommend it. A BA5 course assumes that you already have the necessary basic knowledge of how electrical equipment works. Otherwise, you may not be able to understand or thoroughly absorb all of the new information.

      What exactly is the difference between a BA4 or BA5 certificate and a certificate of competence?

      A certificate of competence is drawn up by your employer after you have successfully completed a qualification course. You are aware of the risks (Informed, BA4) or can carry out small electrical work yourself (Competent, BA5).

      You only receive a valid BA4 or BA5 certificate after passing the entire BA4 or BA5 course.
