Sähkö Oy

What Sähkö Oy does

Sähkö Oy is a Finnish electrical contracting company founded in 1918, operating as two regional units: Sähkö Oy Helsinki (headquartered at Terästie 11, Kerava, serving the Uusimaa region) and Sähkö Oy Turku (now merging with TRP Group Oy). The company delivers electrical installation, renovation, and maintenance services for commercial, industrial, and public-sector clients, with the ability to act as main contractor, designer, or subcontractor depending on project requirements. Its three core service lines are Sähköurakointi (electrical contracting on a contract basis), Sähkötyö laskutyönä (time-and-materials electrical work), and Sähkökunnossapito (ongoing electrical maintenance). Pricing is quote-based and project-specific, with no public price list and no proprietary software platform disclosed.

The business is privately held and operates as a member company of Habeo Group, a property-technology consortium of 30+ companies employing ~1,400 professionals and generating ~€265M in combined revenue. Habeo provides financial expertise, strategic guidance, and shared resources that management credits with improving customer credibility and decision-making. Customer acquisition is relationship-driven through direct sales to facility managers, property owners, and construction project managers, with a project-reference portfolio spanning government (Senaatti-kiinteistöt, HKR-Rakennuttaja, Kirkkonummen kunta), healthcare (Pihlajalinna), retail (HOK/Prisma Myyrmanni), life sciences (Thermo Fisher Scientific), and automotive (Bilia) clients.

In 2024, Sähkö Oy Turku exited consumer and supplies retail to refocus on B2B professional clients, and effective 29 September 2025 it merged with TRP Group Oy to form the largest building services company in the Turku region, combining electrical contracting with TRP's full LVIS (plumbing, HVAC, electrical) capabilities under combined CEO Mikko Ahvenainen. The combined entity projects 110+ employees and €17–20M in revenue, signaling a shift from single-trade electrical contracting to multi-trade building services within the Habeo ecosystem.
