John Jensen VVS

What John Jensen VVS does

John Jensen VVS A/S is a Danish plumbing, HVAC, and sheet-metal (blik) service company headquartered in Hedehusene and operating across Greater Copenhagen since 1962. The company maintains five departments and six branch locations — Hedehusene, Hørsholm, Gentofte, Kastrup/Copenhagen Airport, Copenhagen SV, and Frederiksværk — supported by a fleet of 85 service vehicles and a workforce of more than 200 employees. Service lines span traditional VVS plumbing, HVAC and ventilation, sheet-metal fabrication, and energy optimization, with the latter formalized under the JJ Energi sub-brand launched in 2024. In 2025 the company acquired BLIKOB VVS, adding rope-access installation capability for high-rise and difficult-access sites.

The business serves four primary customer segments: housing associations and property managers (e.g., DEAS, Lejerbo, KAB, FORS Roskilde), commercial and industrial accounts (e.g., ThermoFisher, Copenhagen Airports, Lundbeck, Xellia, Novozymes, DTU), public-sector clients (e.g., Copenhagen Municipality, Nordea Ejendomme), and contractors alongside insurance-driven emergency work. Revenue mechanics combine project-based installations (including heat-pump installations priced in the DKK 130,000–165,000 range per unit), recurring maintenance and service contracts tied to dedicated teams, and premium emergency call-outs.

John Jensen VVS operates as a subsidiary of InstallatørGruppen and is led by CEO Bennet Onsvig and CFO Diana Nielsen. Financial standing is supported by a 2025 AAA credit rating and three consecutive Gazelle Company designations from Børsen, signaling a stable capital base for incremental capability investment. The model is asset- and labor-intensive, with revenue scaling tied primarily to technician headcount, fleet utilization, and contract backlog rather than software or recurring SaaS revenue.
