Renewing an electrical certificate is not just a formality for the filing cabinet. If the certificate for an electrical engineer, lead electrical engineer, instructed person, or certified electrical inspector expires, the individual is no longer permitted to work within that scope. This exposes the company to risks during an inspection, in the event of an accident, or when filing an insurance claim.
Here you will find a clear overview of how long electrical qualifications are valid, when to arrange for an electrical engineer’s re-examination, what applies to a certified electrical inspector, and how to set up your company’s records so you are not caught off guard by an expired date.
Not sure what qualification you need for a specific task? First, read our article on professional competence in electrical engineering. There, we address who is authorized to work on what. Here, we focus on how to maintain the validity of that qualification.
The Short Answer
An electrical engineer and a lead electrical engineer must generally renew their examination certificate every 3 years. An instructed person is re-examined at most after 3 years. A certified electrical inspector holds a certificate valid for 5 years and must take a new examination at the TIČR.
Annual occupational health & safety (OHS) training for electrical equipment does not replace the three-yearly re-examination. These are two separate obligations: ongoing knowledge enhancement and periodic verification of professional competence.
In practice, this is still often called “renewing electrical paragraphs.” However, since the repeal of Decree 50/1978, it is correct to address the specific level of professional competence according to the current regulation: instructed person, electrical engineer, lead electrical engineer, or certified electrical inspector.
Validity of Electrical Certificates: 3 Years or 5 Years
The inspection intervals differ depending on the type of authorization. For electrical engineers, lead electrical engineers, and instructed persons, the interval is three years or a shorter period specified in the record. For a certified electrical inspector, the certificate is valid for five years. It is not enough to simply “be trained” – knowledge must be verified in the prescribed manner.
| Type of Authorization | Validity | What Follows |
|---|---|---|
| Electrical Engineer (§ 6) | 3 years | New examination |
| Lead Electrical Engineer (§ 7) | 3 years | New examination |
| Instructed Person | max. 3 years | Re-examination |
| Certified Electrical Inspector (§ 8) | 5 years | New examination at an authorized organization |
For instructed persons, it is worth emphasizing: the periodic re-examination is repeated at most every three years, in the form of a proper knowledge verification. This is not the same as the annual safety training, which the employer provides in addition to this interval.
Certificates issued under the old Decree 50/1978 are assessed after July 1, 2022, according to the transitional provisions of the new regulation, and the specific date, scope, and type of certificate are always decisive. If you are dealing with “Decree 50 validity” for a specific person, verify their last examination, the three-year validity, and the scope of activities. For certified electrical inspectors, verify the validity and scope of their certificate in the public TIČR database.
Electrical Engineer Re-examination: How the Renewal Works
The examination for an electrical engineer and lead electrical engineer is arranged by the employer – for self-employed persons, this responsibility logically falls directly on them. The examination does not have to be conducted by an internal company employee; an external certified electrical inspector or a specialized company is often used to conduct the examination in the prescribed manner. The principle, however, remains the same: renewal is not equivalent to sitting through a lecture. It is a verification of knowledge.
A certified electrical inspector takes a new examination at an authorized organization, which is the Technical Inspection of the Czech Republic (TIČR). Upon successful completion, they issue a certificate valid for five years. A certified electrical inspector’s certificate is publicly searchable – the TIČR database shows the expiry date and the scope of the certificate.
Let’s also separate two things: the periodic examination (above) and periodic training. In addition to the examination itself, the employer must ensure qualification enhancement – typically OHS training for electrical equipment. If the company does not have its own internal regulation setting an interval, a minimum frequency of once per year applies.
Expired Electrical Certificate: What Risks the Company Faces
The consequence is simple: until a successful renewal, the person in question must not perform the activity to which the certificate relates. There is no grace period just because you have already booked an examination date. An expired certificate means a stop sign for that scope of work.
For a certified electrical inspector, it is even stricter – an inspection report signed by someone whose certificate has expired is invalid. This is true even if the signature occurred during an inspection that began while the certificate was still valid. The decisive factor is the date of signature, not the date the work started.
The consequences can manifest in two lines. During an SÚIP inspection, the Labor Inspectorate may assess such a situation as a breach of the employer’s duty to ensure that only professionally competent persons work on electrical equipment. The second line is insurance-related – if damage occurs and it turns out that an inspection report or operational activity was based on an expired qualification, the insurance company may reduce or refuse the claim. Not automatically, but it is a possibility.
Tracking Electrical Certificate Validity in the Company
Relying on each employee to keep track of their own certificate is the start of a problem. An employee leaves, forgets, or confuses the periodic examination with the annual training. The responsibility for ensuring that only a person with a valid certificate works on electrical equipment lies with the employer.
The solution is a simple authorization matrix – a table listing the type of certificate, the date of the last examination, and the expiry date for each relevant person. Notifications should be set at least one month in advance, ideally two – to allow time to organize an examination date even during holidays or sick leave.
Along with tracking the date, it is wise to also check the scope. An electrical engineer with a certificate for low voltage cannot automatically work on high voltage – the scope stated on the certificate is decisive. For certified electrical inspectors, verification is easy: the public TIČR database will tell you within a minute whether the certificate is valid and for what scope.
For instructed persons, the periodicity is a maximum of three years – and this is where most violations occur in practice, as it is often confused with the annual OHS training, which is something different.
Practical Authorization Matrix
A well-maintained record doesn’t have to be complicated. The important thing is that it contains the data allowing you to quickly see who is authorized to do what work and when a renewal needs to be addressed:
- Employee name,
- Level of professional competence,
- Voltage range and type of equipment,
- Date of last examination or instruction,
- Expiry date,
- Planned renewal date,
- Reference to the stored certificate or record,
- Person responsible for monitoring the renewal.
Set reminders at least one month in advance. For larger operations, two reminders are worthwhile: the first two months before expiry, the second one month before. This gives the company time to schedule the examination, account for vacations, shifts, and any potential corrections to documents.
If you are just setting up your records, start simple: take the list of people working on electrical equipment and find the latest certificate for each one. Only then should you worry about color-coded spreadsheets and automatic reminders. First, you need to know who is compliant, whose validity is nearing its end, and who must no longer work.
How SOHE Can Help
Monitoring deadlines, preparing for examinations, and periodic refresher training is exactly what we handle for companies daily. For electrical engineers and lead electrical engineers, we arrange the complete re-examination process – from organization to conducting the examination in the prescribed manner. We re-examine instructed persons so that the re-examination meets the requirements of the three-year periodicity, not just an annual routine instruction.
For companies wanting to save on administration, we maintain validity records and provide advance notice of whose deadline is approaching. For a certified electrical inspector, the examination itself takes place at TIČR, but we can also help you prepare for it – and if you need an electrical inspection directly, you have the assurance that it will be signed by an inspector with a valid certificate.
Our employee training service covers the entire issue – from electrical engineers and instructed persons to periodic training. Get in touch, and we will review your situation and set up a system so that no expired date catches you by surprise. You can write to us via our non-binding inquiry form.
Frequently Asked Questions
How often must an electrical engineer’s certificate be renewed?
Every three years. After three years from the last examination, a new one must be taken – completing training is not enough; knowledge must be verified in the prescribed manner.
Is annual safety training enough for electrical engineers instead of an examination?
No. Annual training is an additional obligation, not a substitute for the three-yearly examination. These are two separate things – periodic knowledge verification once every three years and ongoing qualification enhancement at least once a year.
What about people who still show certificates under the old Decree 50?
First, verify the date, scope, and type of certificate. For electrical engineers and lead electrical engineers, monitor the three-year validity of the examination certificate. For a certified electrical inspector, verify the certificate in the public TIČR database. If the validity or scope does not match the work being performed, a new examination must be taken according to the current regulation.
What if a certified electrical inspector’s certificate expires in the middle of an ongoing inspection?
The decisive factor is the moment the inspection report is signed. If the certificate expires before the inspector signs the report, that inspection report is invalid – regardless of the fact that the work began while the certificate was valid.
How can I verify that a certified electrical inspector has a valid certificate?
Validity can be checked in the public TIČR database. It is an open register where you can find the status and scope of authorization by name or certificate number. We recommend doing this whenever you start working with a new inspector.
