Hollander Techniek brings four certifications together at Kiwa and combines audits where possible

Delivering quality, keeping commitments and continuously improving. These are natural starting points for Hollander Techniek. The family owned company, with 700 employees, advises, designs, implements and manages technical installations and systems. From five locations, the technical services provider and systems integrator develops sustainable, comprehensive solutions for customers in sectors including commercial buildings, industry and retail.

Framework for quality improvement

To demonstrate the quality of its operations and further develop the organization, Hollander Techniek works with several management system standards. Since 2021, the company has been certified by Kiwa for ISO 27001, the standard for information security. In 2026, Hollander Techniek also transferred its existing ISO 9001, ISO 14001 and CO2 Performance Ladder certifications to Kiwa. This means that the company has a single certification partner to assess its quality management, environmental management, CO2 reduction and information security.

Quality, safety, sustainability and information security have been part of Hollander Techniek's operations for many years. Certification provides structure and a framework for organizing these areas and continuously improving them. ‘Certification provides a framework for what we strive to achieve every day: delivering quality, keeping commitments and organizing our work carefully,’ says Marjolein Hoefsloot, Quality, Health, Safety and Environment (QHSE) advisor at Hollander Techniek. ‘We continue to work on clear agreements, well defined responsibilities and ways of working that reflect day to day practice.’

Independent confirmation

Clear internal agreements and responsibilities help employees understand what’s expected of them and how they can contribute to the organization's objectives. At the same time, certification makes the company's way of working transparent to customers and other stakeholders. It provides independent confirmation that Hollander Techniek has its processes assessed against the relevant standards. The certifications also align with the requirements many customers place on their technical partners. For Hollander Techniek, they are therefore not only a way to improve its own operations but also a way to demonstrate the reliability of its services.

The collaboration between Hollander Techniek and Kiwa began in 2021 with ISO 27001, the international standard for information security. The positive experiences gained through this collaboration provided the basis for transferring the ISO 9001, ISO 14001 and CO2 Performance Ladder certifications to Kiwa in 2026 as well. ‘The ISO 27001 certification process gave us the confidence to transfer these three certifications to Kiwa too,’ says Hoefsloot. ‘We value the Kiwa auditors' expertise, the positive working relationship and the opportunity to assess multiple standards as part of an integrated audit process.’

Good preparation

By combining audits where possible, Hollander Techniek can organize preparation and scheduling more efficiently. This reduces the demands on employees and minimizes the impact on day to day operations. As a result, the focus can remain on customer projects and services as much as possible. Good preparation was important in this process. Hollander Techniek and Kiwa reviewed in advance how the different audits could be combined and what information would be needed. Clear agreements about scheduling helped ensure that the process ran smoothly.

A certification audit is not just about assessing processes and documentation. The discussions about how these processes are applied in daily practice are what provide valuable insights. Hollander Techniek experienced this during the combined audit process. ‘The audits provided plenty of opportunity for in depth discussions about our processes and how we apply them in practice,’ says Hoefsloot. ‘In addition to the assessment itself, these discussions provided valuable insights for further improvement.’

Opportunities for improvement

In addition to assessing compliance, audits provide an opportunity to look at existing practices from an external perspective. The discussions help Hollander Techniek identify specific opportunities for improvement and further develop the organization. ‘That’s also where we see the value of an audit: working together to see how we can further strengthen what we do.’

The Kiwa auditors' expertise and approachable manner played an important role. According to Hoefsloot, the process provided an opportunity to discuss working practices openly and take a critical look at how things work in practice. This combination of a thorough assessment and practical insights fits well with the way Hollander Techniek likes to work with its partners.

Shared responsibility

Management systems are only effective if they are not just documented on paper but also applied in daily work. That’s why it’s important for employees to understand the role they themselves play in quality, sustainability and information security. The certification process has further strengthened this awareness.

By discussing processes and responsibilities during preparation and audits, the standards become more concrete and more clearly connected to employees' work. ‘It reinforces the understanding that working carefully and continuously improving are shared responsibilities,’ says Hoefsloot. ‘This fits with the theme “Hollander Eigen, The Future Is Ours” (Hollander Own, The Future Is Ours), which emphasizes that our employees are building the quality and development of the organization together.’

Continuing to develop and improve

The four certifications support Hollander Techniek in demonstrating that it manages and continuously improves quality, environmental management, CO2 reduction and information security. Periodic audits help assess progress, identify areas for attention in a timely manner and implement improvements.

According to Hoefsloot, maintaining certification requires ongoing attention. ‘Our way of working must continue to reflect day to day practice and the development of the organization. That’s why we continue to invest in our employees, digitalization and the improvement of our processes and services. The certifications provide structure and a framework for this.’
