Toelatingsorganisatie Kwaliteitsborging Bouw

What Toelatingsorganisatie Kwaliteitsborging Bouw does

Toelatingsorganisatie Kwaliteitsborging Bouw (TloKB) is a Dutch zelfstandig bestuursorgaan (independent administrative body) established by the Minister of Binnenlandse Zaken en Koninkrijksrelaties (BZK) on 22 April 2022 to oversee construction quality assurance in the Netherlands. The organization administers three statutory systems: the KB-stelsel for quality assurance of newly built structures in consequence class 1 (mandatory since 1 January 2024), the EKV-stelsel for recognizing quality declarations on building products and processes via designated assessment guidelines (BRL's) and certification bodies, and the CO-stelsel for certifying companies performing work on gas combustion installations (mandatory since April 2023). TloKB admits instruments, designates certification bodies and schemes, maintains three public registers of admitted instruments, recognized quality declarations, and certified installers, and exercises supervision and enforcement powers on behalf of the Minister.

TloKB does not develop a commercial technology product; its operational stack consists of a public website (tlokb.nl) on the Platform Rijksoverheid Online (PRO), public registers, online application forms, and since 2024 a REST API plus Excel template for instrument providers to submit gevolgklasse 1 project data. It uses Piwik Pro for web analytics and meets WCAG 2.2 Level A/AA accessibility requirements under the Wet digitale overheid.

The revenue model is built entirely on government-mandated statutory fees charged to instrument providers, certification bodies, and scheme managers (e.g., 2026 KB-stelsel gevolgklasse 1 tariffs: €37,321 one-time admission per instrument, €27,926 annual registration per instrument, €11.91 per construction project/dwelling in supervision fees; EKV fees from €62/year per quality declaration to €2,554 for CI designation; CO CI designation €12,963). TloKB does not sell subscriptions or commercial products, does not operate outside the Netherlands, and reports to the Ministry of BZK without private equity, debt, or external shareholders.

Revenue model

1. Regulatory fees from instrument providers (KB-stelsel): Instrument providers in the quality assurance system pay a one-time admission fee for instrument admission, annual registration and modification fees, and contribute to TloKB's supervision costs based on the number of construction projects. Tariffs for consequence class 1 (2026): admission €37,321 per instrument (one-time); registration €27,926 per instrument per year; supervision €11.91 per construction project/dwelling per year.
2. Regulatory fees from certification bodies and quality declarations (EKV-stelsel): Scheme managers and certification bodies pay fees for the admission and designation of assessment guidelines, designation as a certification body for the EKV system, and recognition/registration of quality declarations. 2026 tariffs: designation as certification body €2,554; assessment guideline treatment €529 per BRL; modification per BRL €387; BRL registration fee €76 per year per BRL; KV registration fee €62 per year per KV.
3. Regulatory fees from certification bodies (CO-stelsel): Certification bodies for gas combustion installations pay a designation fee for being appointed as a certification body for issuing certificates for work on gas combustion installations. 2026 tariff: CI designation €12,963.

Core offering

TloKB oversees and maintains the national quality assurance system for the Dutch construction sector under the Wet Kwaliteitsborging Bouw. It operates the registration and recognition frameworks for quality assurance instruments, building product quality declarations, and combustion-gas-free gas installation certification, and it exercises statutory supervision and enforcement over certified scheme holders and installers. Its core output is the maintenance of four public registers and the granting of formal recognitions and certifications required by Dutch construction law.

Product overview

TloKB operates as a government quality assurance organization with three interconnected certification and supervision systems: (1) KB-stelsel for construction quality assurance covering buildings in consequence class 1, with approved instruments and registered quality assessors; (2) Erkende Kwaliteitsverklaringen system for recognizing quality declarations on building products and processes through designated assessment guidelines and certification bodies; and (3) CO-VRIJ certification for gas combustion installation work, mandatory since April 2023. All systems maintain public registers, and TloKB conducts ongoing supervision and enforcement across all three domains.

Partnerships

Two partnerships are on record, tiered core.

• Raad voor Accreditatie (RvA) - Dutch Accreditation CouncilcoreStrategic or Co-development Partner · 22 April 2022The Raad voor Accreditatie (RvA) is the national accreditation body of the Netherlands. It assesses whether organizations competently evaluate whether products or services meet stated requirements. TloKB cooperates with RvA in the EKV and CO systems. TloKB designations follow evaluation and accreditation by RvA.
• Inspectie Leefomgeving en Transport (ILT) - Human Environment and Transport InspectoratecoreStrategic or Co-development Partner · 22 April 2022The ILT is the Dutch supervisory authority for infrastructure, transport, environment, and housing. It oversees compliance with laws and regulations and issues permits. ILT checks whether construction products are correctly provided with CE marking. The ILT is a service component of the Ministry of Infrastructure and Water Management.

Broad incumbents

• SGS Société Générale de Surveillance: One of the world's largest third-party TIC groups offering construction product certification, building inspections, and verification services. Comparable to TloKB as a third-party assurance provider but operates commercially across many geographies and sectors rather than as a single-jurisdiction statutory authority.
• TÜV Rheinland Group: International TIC group performing construction product testing, certification, and inspection, including CE-related verification under EU regulation. Compares to TloKB's role in supervising quality declarations tied to Building Decree compliance.
• Inspectie Leefomgeving en Transport (ILT): Dutch supervisory authority that checks CE marking on construction products and oversees housing-related regulation on behalf of the Ministry of Infrastructure. Functions as a parallel statutory supervisor within the same regulatory stack TloKB sits in.
• Bureau Veritas: Global TIC incumbent providing building and infrastructure conformity assessment, certification, and supervisory services. Provides a useful benchmark for how certification/supervision scale economics work — although privately commercial rather than statutorily appointed.

Direct peers

• Stichting Bouwkwaliteit (SBK): Dutch foundation historically involved in the recognized quality declarations (erkende kwaliteitsverklaringen) system for building products, which is one of the three stelsels TloKB now supervises. Direct functional overlap in BRL assessment guidelines and EKV registration.
• Kiwa N.V. Dutch-based Testing, Inspection and Certification (TIC) company that operates accredited certification schemes and issues product/process certifications that flow into the EKV-stelsel which TloKB supervises. Kiwa is functionally the most direct TIC counterpart in the Dutch construction product certification chain TloKB regulates.
• Raad voor Accreditatie (RvA): Dutch national accreditation body that accredits the certification bodies (CI's) whose designations TloKB grants. Although formally a partner rather than competitor, RvA performs the upstream accreditation function that determines which CI's are eligible for TloKB designation — making it the structurally closest peer in the Dutch QA pyramid.
• SKG-IKOB: Dutch certification body designated under the EKV and KB-stelsels, issuing product certifications and quality declarations that TloKB supervises. Operates as one of the certification-instellingen TloKB oversees.

Emerging players

• Building Safety Regulator (UK): UK statutory regulator for building safety established post-Grenfell to oversee higher-risk buildings. Provides a cross-jurisdiction analogue to TloKB's KB-stelsel for higher consequence classes, useful for benchmarking how supervisory scope evolves.

Regional players

• ISSO: Dutch knowledge institute for building services and HVAC that develops technical guidelines referenced in the KB-stelsel and broader Dutch quality infrastructure. Adjacent role: produces reference documents that feed into TloKB-supervised schemes, with a national-only scope that parallels TloKB.
