Wijzer

What Wijzer does

Wijzer BV is a Belgian private limited company specializing in building certification and technical inspection services, headquartered in Geluwe with a second office in Wevelgem. Formed in September 2024 through the merger of three predecessor firms (Home2Check, Enairko, and Bureau Vandenbogaerde), the company operates under the trade name 'Wijzer Keuringen' and serves residential property owners (particulieren) and construction professionals (architects, contractors, developers) across West-Vlaanderen and Oost-Vlaanderen provinces.

The company's core offering is a comprehensive certification package built around three regulatory pillars: residential and non-residential Energy Performance Certificates (EPC), asbestos attestations (asbestattesten) for pre-2001 buildings, and EPB (Energy Performance of Buildings) reporting for new builds and major renovations. These are complemented by twelve add-on modules including ventilation reporting, safety coordination, blower door airtightness testing, heat loss calculations, drainage inspection, electrical inspection, fuel oil tank inspection, condition reports, and demolition follow-up plans. All services depend on certified expert accreditation (erkende deskundigen) issued under Flemish regulation, and inspection work is performed on-site by multi-credentialed field experts, with laboratory analysis subcontracted for asbestos sampling.

The business model is project-based professional services with custom quotes per engagement. Customers request quotes via the company website, phone, or email; certified experts then conduct on-site visits (often combining multiple certifications in a single visit) and deliver reports such as EPCs within published turnaround times (3 working days for residential EPC). Revenue is generated per certificate/inspection, with additional out-of-scope work billed at €75/hour plus €0.50/km travel. The company operates with 6 employees, maintains a direct-to-consumer distribution model with no resellers or intermediaries, and pursues geographic growth through regulatory tailwinds such as the expanded non-residential EPC obligations effective January 2025 and 2026.

Expansion highlights5 records

Regional players

• Homegrade: Brussels-based energy and housing advice centre providing EPC-adjacent information and referrals to certified experts for the Brussels-Capital Region. Comparable as a publicly supported hub routing consumers to building certification services, but operating in a different region than Wijzer's Flemish focus.
• Energieloket: Flemish energy advice platform supporting homeowners with renovation guidance, premium applications, and certified-expert referrals. Comparable because it sits in the same Flemish regulatory ecosystem that drives Wijzer's customer demand and can act as a referral channel.

Broad incumbents

• Bureau Veritas Belgium: Global TIC (testing, inspection, certification) major with a Belgian footprint offering building and infrastructure inspection and compliance services. Comparable as a broad incumbent providing third-party inspection/certification work in the same regulated environment where Wijzer competes.
• Kiwa Belgium: European TIC firm active in Belgium providing testing, inspection, and certification including for construction and energy performance. Comparable as an accredited certification body addressing overlapping building compliance and energy performance domains.
• Vinçotte: Belgian TIC incumbent providing inspection and certification for buildings, electrical installations, pressure equipment, and industrial assets. Comparable as a long-established accredited inspection body with overlapping electrical and boiler/tank inspection services that overlap with Wijzer's electrical keuring and stookolietankkeuring lines.
• Buildwise (formerly WTCB): Belgian construction innovation and research centre supporting the building sector with technical advice, certification frameworks, and inspection-adjacent services. Comparable because it shapes the Flemish standards and accreditations that Wijzer operates within and offers overlapping technical expertise to construction professionals.
• SGS Belgium: Global testing, inspection, and certification group operating in Belgium across construction, environmental, and industrial compliance. Comparable as a broad incumbent offering building-related inspection and certification services that overlap with Wijzer's regulated compliance work.

Direct peers

• Certifisc: Belgian accredited building inspection bureau offering EPC and related energy performance certifications. Comparable as a direct competitor delivering the same Flemish EPC services to residential and non-residential property owners with similar accredited-expert positioning.
• BCCA (Belgian Construction Certification Association): Belgian accreditation and certification body for construction products and processes, including building-related certification schemes. Comparable as a directly operating certification services firm within the same Belgian construction compliance framework as Wijzer.

Emerging players

• EPC Vlaanderen (accredited experts): Aggregator/portal of accredited Flemish EPC experts that channels consumers to certified energy advisors. Comparable as an emerging digital intermediary in the same Flemish EPC marketplace where Wijzer competes for end-customer acquisition.
