What Bänziger Zollinger does

Bänziger + Zollinger GmbH is a privately held, family-controlled Swiss electrical safety inspection and consulting firm founded in 2002 by Daniel Bänziger and Martin Zollinger, headquartered in Dietikon with branch offices in Mellingen, Eggenwil, Baden, and Wohlen. The firm provides periodic electrical safety inspections (Elektrokontrollen), acceptance controls (Abnahmekontrollen), final inspections (Schlusskontrollen), and accredited specialized inspections covering NIV-regulated installations, medically used rooms, explosion protection zones, tank installations, national road electrical infrastructure, and lightning protection systems under Swiss Accreditation Service (SAS) accreditation granted 27.02.2017. Service delivery relies on a fleet of specialized measurement instruments (network analyzers, impedance meters up to 80kA, Metrel/Benning device testers, Fluke grounding meters, thermal cameras) and a team of federally certified electro-safety consultants and lightning protection specialists (VKF-Blitzschutzfachmann).

The company generates revenue through three streams: (1) professional services fees for periodic, acceptance, final, accredited, thermography, lightning protection, and switchgear cleaning inspections, priced quote-based on installation scope; (2) hardware sales/rental of emergency power systems (Notstromanlagen, 8-90 kVA); and (3) recurring professional training courses held at the Mellingen facility. Demand is fundamentally regulatory-driven: Swiss NIV mandates periodic inspection cycles (5, 10, or 20 years depending on property type), with property owners legally obliged to commission inspections; network operators notify property owners ahead of deadlines, creating a quasi-inbound customer flow. A contracted relationship with AGV Aargauische Gebäudeversicherung (since 2013) provides recurring lightning protection inspection work in Canton Aargau. Customer concentration spans residential, commercial, industrial, and institutional segments, with a visible enterprise logo list including ABB, Novartis, Credit Suisse, UBS, ETH Zürich, Prime Tower, Flughafen Zürich, Holcim, and Syngenta.

Ownership is concentrated within the Zollinger family following a 2011 succession exit by co-founder Daniel Bänziger. Daniel Zollinger (son of co-founder Martin Zollinger) assumed the Managing Director role in 2025 alongside an expanded executive board (Roman Meier as Deputy MD, Jana Rubin as Head of Administration) following the retirement of Martin and Silvia Zollinger. The firm holds no external investors, has not announced funding rounds, and has not been acquired or IPO'd. Geographic footprint is concentrated in the Aargau and Zürich cantons with selected customers elsewhere in Switzerland, and quality credentials include ISO 9001 (introduced 2013), IQNET, SQS, and SIS Verzeichnis listings.

Quantifiable outcome

• Companies with 20-year inspection cycle (residential) must complete safety certification; those with 10-year (agricultural/commercial) or 5-year (assembly spaces, gas stations) cycles must also comply. Failure to submit safety certificate results in network operator reporting to ESTI (Eidgenössisches Starkstrominspektorat).

Broad incumbents

• Intertek Switzerland: Global TIC group with a Swiss entity offering electrical, industrial, and product safety inspection services. Comparable in scope and customer type, though with a much broader international footprint than Bänziger + Zollinger.
• SGS Switzerland: World's largest TIC company with operations in Switzerland, providing industrial inspection, testing, and certification services. Competes for the same large industrial customer base (e.g., pharma, cement, automotive) that Bänziger + Zollinger serves.
• Bureau Veritas Switzerland: Global testing, inspection and certification (TIC) major with a Swiss entity that competes for industrial and infrastructure electrical inspection contracts. Broader portfolio and international scale, but overlaps directly with Bänziger + Zollinger in industrial and commercial electrical safety work.
• TÜV SÜD Switzerland: Global TIC provider with Swiss operations offering electrical safety, building, and infrastructure inspection. Competes for the same large-enterprise electrical and safety contracts that anchor Bänziger + Zollinger's customer list.
• DEKRA Switzerland: German-headquartered global TIC firm with a Swiss presence providing industrial, electrical, and building inspection services. Overlaps with Bänziger + Zollinger in industrial and infrastructure safety inspection markets.

Others

• VSEI (Verband Schweizerischer Elektro-Installationsfirmen): Swiss trade association for electrical installation companies. Adjacent ecosystem participant - not a direct competitor, but its members perform NIV-permitted installation work and feed demand into Bänziger + Zollinger's acceptance and final inspection services.
• EIT.swiss: Swiss trade association for electrical and information technology installers. Indirectly comparable: it shapes the regulatory and training ecosystem (including the NIV Art. 13/14/15 courses Bänziger + Zollinger teaches) and represents the installation-firm customer base the company serves.

Direct peers

• Electrosuisse: Swiss electrical industry and standards organization (Fehraltorf) that operates accredited inspection services and is the principal national player in the same regulatory space Bänziger + Zollinger serves. Most directly comparable peer for accredited NIV and lightning protection inspection work in Switzerland.
