Herkeuring Simplified: How to Book Your Follow-Up Inspection After Corrective Actions

If your installation did not pass the first inspection, the next step is clear: complete the corrective actions and arrange a herkeuring, or follow-up inspection. This stage is often where companies want the most clarity. What needs to be ready? When can you schedule it? And how do you make sure the second visit runs smoothly? This guide explains how a herkeuring works at Wassenaar Inspecties, what to expect before, during, and after the appointment, and how to prepare efficiently.

A follow-up inspection is not just an administrative step. It is the moment when previously identified issues are checked again to confirm that the necessary improvements have been carried out correctly. That makes the process important for safety, compliance, and peace of mind.

What is a herkeuring?

A herkeuring is a new inspection that takes place after defects or deficiencies from a previous inspection have been corrected. During the first inspection, the inspector prepares a detailed report listing the identified defects and recommendations for improvement. Once those points have been addressed, you can request a re-inspection.

In simple terms:

  1. The initial inspection identifies issues.
  2. Corrective actions are completed.
  3. A herkeuring verifies whether the corrections were made properly.

This applies to inspection work where deficiencies were found and a second assessment is needed after repairs or adjustments.

Why a follow-up inspection matters

A failed inspection does not mean the process stops. It means there is a defined route toward improvement. Wassenaar Inspecties supports compliance with applicable standards, safety regulations, legal obligations, and insurance conditions, depending on the type of inspection and your situation.

A follow-up inspection helps you:

In practice, a herkeuring is the bridge between a report with findings and a documented result after those findings have been addressed.

What happens after the first inspection?

After an installation or piece of equipment does not pass, the inspector issues a detailed report with the observed defects and recommendations. This report forms the basis for the corrective work.

Wassenaar Inspecties works independently and focuses exclusively on inspections. If repair work is required, the customer’s own installer or chosen external company carries it out. This independence matters because the inspection remains separate from the repair process.

The usual sequence

1. Review the inspection report

Carefully review the defects and recommendations listed in the report. These findings define what must be corrected before the follow-up inspection.

2. Arrange corrective work

Use your own installer or another external company to complete the required adjustments. You are free to choose the party that performs the repairs.

3. Document serious repairs

If there was a serious finding, the customer is expected to resolve the issue through an external company and send the Herstelverklaring back so an inspector can assess whether the repairs were completed correctly.

4. Request the herkeuring

Once the corrective actions are finished, you can request a re-inspection.

How to book your herkeuring

Booking a herkeuring is easiest when all corrective work has been completed and the site is ready for inspection. This helps avoid delays and makes the second visit more productive.

Wassenaar Inspecties can be reached during office hours:

Estimated waiting time

The waiting time depends on the size of the installation. If you have 1 or 2 fuseboxes, the estimated waiting time is around 3 weeks.

For larger or more complex installations, planning may vary. Booking as soon as corrective work is nearing completion can help you move forward without unnecessary downtime.

What to prepare before the follow-up inspection

Good preparation can make a herkeuring much smoother. The goal is simple: ensure that the corrected installation, equipment, or system is accessible, safe to inspect, and supported by the right documentation.

General preparation checklist

Before any inspection takes place, Wassenaar Inspecties sends the client an Inspectierapport. This form must be filled in and signed so there is permission to work at the location and in the fusebox.

For the follow-up inspection, it helps to make sure:

Additional preparation for Scope 12

For a Scope 12 inspection, it is preferred, where possible, to provide:

These documents can help support a clear review of the solar panel installation during inspection activities.

What to expect during the herkeuring

During the inspection, the client is advised not to interfere with the work of the inspector. Clear access and an undisturbed working environment help the inspector perform the necessary checks efficiently.

The exact content of a follow-up inspection depends on the type of original inspection and the issues that were previously identified.

Scope 8 follow-up inspection

During a Scope 8 inspection, Wassenaar Inspecties carries out:

These are used to verify compliance with safety standards and Arbowet requirements.

Scope 10 follow-up inspection

During a Scope 10 inspection, Wassenaar Inspecties carries out:

This combination helps identify potential fire hazards and assess whether previously identified issues have been corrected.

Scope 12 follow-up inspection

During a Scope 12 inspection, Wassenaar Inspecties inspects solar panel installations to verify safe operation and compliance with relevant standards.

Inspection equipment used during re-inspections

A herkeuring relies on suitable, calibrated instruments. Wassenaar Inspecties uses different equipment for different SCOPE inspections, and all instruments are calibrated on time.

Scope 8 equipment

For SCOPE 8, the equipment includes:

Scope 10 equipment

For SCOPE 10, Wassenaar Inspecties uses the same tools as for Scope 8, plus thermal imaging with:

Scope 12 equipment

For SCOPE 12, the equipment includes:

What happens after the herkeuring?

After every inspection, an official report is prepared by the inspector. This gives you a documented outcome of the follow-up visit.

If everything that needed correction has been addressed properly, the re-inspection helps bring the process to a clear conclusion. If more action is still needed, the report will show what remains to be improved.

That clarity is one of the biggest advantages of a structured herkeuring process: you know exactly where you stand.

Practical tips to make your herkeuring go smoothly

If you want to avoid delays and make the follow-up inspection as efficient as possible, focus on preparation and timing.

Best practices before you book

Best practices on the day

Why companies value an independent inspection process

Wassenaar Inspecties focuses only on inspections and does not carry out repair work. That independence helps keep the inspection process objective. The company states that it has no interest in rejecting an installation because repair work is not part of its business.

For customers, this creates a clear division:

This can make the herkeuring process easier to understand and manage.

Experience, qualifications, and service approach

Wassenaar Inspecties works with experienced inspectors, modern equipment and software, and emphasizes a fast, reliable, and effective approach.

Inspector qualifications include:

The service approach is also designed to support customers through the inspection process. Wassenaar Inspecties is available during office hours to answer questions and guide clients through the inspection journey.

A quick answer: when should you request a herkeuring?

That simple step can save time and make the second visit much more efficient.

Conclusion: move from corrective actions to confidence

A herkeuring is the logical next step after corrective actions have been completed. It gives you a clear way to verify that the reported defects have been addressed, supports compliance efforts, and provides an official report after the follow-up visit.

The process becomes much easier when you prepare properly: complete all repairs, return the required documentation, keep the installation accessible, and book the appointment once everything is ready.
