What Rorgruppen does

Rörgruppen AB is a Stockholm-based VVS (heating, plumbing, and sanitation) installation subcontractor founded in 1983, specializing in pipe installations for new construction, renovations, and technically complex facilities. The company delivers five core service lines: qualified installations for central/complex buildings, tenant and retail fit-outs, new construction and pipe replacements (stambyten), office property installations, and advanced pipe installations for medical and industrial facilities such as surgical clinics and pharmaceutical production units. Rörgruppen has executed pipe replacements in approximately 7,000 apartments and new construction in approximately 3,600 apartments, including the 850-unit Essinge Udde project on Lilla Essingen.

The company operates exclusively as a B2B subcontractor within the greater Stockholm region, serving general contractors (NCC, Skanska, JM, Einar Mattsson, Zengun, Novogruppen), real estate developers (Vasakronan, Atrium Ljungberg, Pembroke, Niam, Jernhusen, Tenet), and public sector clients (Region Sörmland). Revenue is generated through project-based lump-sum contracts, partnering agreements, and collaborative contracts (samverkansentreprenad). The company holds RCLS, Säker Vatten, ISO quality, and environmental management certifications, and participates in sustainability-certified projects targeting LEED Platinum and BREEAM ratings.

Rörgruppen became part of the Instalco Group in March 2014 when private equity firm FSN Capital acquired it alongside four other installation firms to form Instalco, which now operates approximately 150 subsidiaries across Sweden, Norway, and Finland with combined revenue of approximately 14 billion SEK and 6,000+ employees. Rörgruppen maintains operational autonomy within the group structure while accessing cross-subsidiary collaborative bidding on large projects such as the 1.7 billion SEK Framtidens sjukhus hospital program. Göran Johnsson led the company as VD for 35 years before transitioning to Senior Advisor on September 30, 2023; Martin Jarl assumed the VD role on October 1, 2023.
