What Konstel does
Konstel AS, now operating under the Nimlas brand, is a Norwegian-headquartered technical installation company that is part of the Nimlas Group, a Nordic conglomerate operating across Norway, Sweden, and Finland. The company delivers technical installation services including electrical systems (Elektro), HVAC and ventilation, plumbing (VVS), fire safety (Brannsikkerhet), sprinkler systems, and building automation (Automasjon) for residential, commercial, industrial, and maritime/offshore customers. Service delivery is organized through a federation of 36–38 independent local installation companies in Norway (and approximately 140 companies across the Nordics with ~5,000 professionals total), each retaining local decision-making authority while leveraging centralized back-office support.
The core operating model is an acquisition-driven roll-up of fragmented regional electrical and technical installation firms. Each acquired entity retains its local brand identity (e.g., Elman Gruppen, EL24, Elteam, HGN Elektro, Miljø Elektro, Mikenti) and operates independently in its geography, while Konstel/Nimlas consolidates purchasing power, competence development, digital tooling, and corporate functions at the group level. Underlying technology is service-oriented (project execution, maintenance contracts) supplemented by centralized digital tools, with no proprietary software product disclosed. Products and services are delivered through direct field sales and project-based engagement by the local subsidiaries.
Revenue is generated through professional services — primarily project-based installation contracts and recurring maintenance/service agreements — priced via direct customer engagement and project quotations rather than public pricing. Customer segments are vertical-oriented, dominated by the building and construction sector (residential, commercial, industrial), with a secondary segment in maritime/offshore technical services. Nimlas Norway reports group revenue of approximately NOK 3.3 billion with ~1,800 employees, while Konstel AS specifically surpassed NOK 2 billion in annual revenue following the Elman acquisition in 2023–2024.
