EST – Empresa de Serviços Técnicos is a Leiria contractor for industrial electricity, instrumentation and automation, founded on 11 April 1990, which sold 70% of its capital to France’s Vulcain Engineering in December 2025 while keeping family management (EST – Empresa Serviços Técnicos, S.A., NIF 502359196). In the Nordics it has a Swedish branch registered in 2014 and a Norwegian branch registered in 2023, and its website says it collaborates in building data centres for TikTok in Norway.
The Leiria company was founded on 11 April 1990 and works in industrial electricity, automation, robotics and systems, instrumentation, electrical boards, energy, HVAC and technical maintenance, for sectors ranging from pulp and paper, cement and glass to data centres. Its About page names Spain, Sweden, Denmark, Angola, Colombia and Uruguay as markets beyond Portugal, and the site footer lists EST Denmark, EST Sweden and EST Norway as group companies. In December 2025 the Leiria press reported that EST had sold 70% of its capital to the French group Vulcain Engineering while preserving family management, and Jornal de Negócios put the workforce at 270; EST now describes itself as part of the Vulcain Engineering Group.
The Swedish branch came first. EST - Empresa De Services Técnicos S.A Filial (org. no. 516408-9665) was registered on 27 February 2014 to carry out electrical installations, is registered for VAT and as an employer, and uses a c/o address at Aspia AB in Jönköping. The Norwegian branch, EST - EMPRESA SERVICOS TECNICOS S.A (NUF, org. no. 932541661), entered the Brønnøysund register on 7 December 2023 under electrical installation work, with a registered activity of designing electrical solutions and planning and carrying out electrical work. EST’s Data Centers page states that it collaborates in the creation of data centres for TikTok in Norway; in March 2024 the company reported a visit by its administration to the “Beluga Project” data-centre works in Norway, and in April 2024 it marked its 34th anniversary at its sites in Luxembourg, Norway and Sweden. Its website also carries a customer testimonial credited to a Valmet “Böras Project”, and in December 2024 EST sponsored the DATACENTER FORUM in Stockholm.
Data-centre construction in the Nordics depends on specialist electrical contractors, and EST is one of the Portuguese firms that has followed that work north, with registered branches in both Sweden and Norway. Its Swedish branch has been on the register for more than a decade, and the Vulcain deal now places that Nordic footprint inside a larger French engineering group. For the wider trend, see Mecwide’s Norwegian data-centre work.
In July 2026 EST announced that it had been shortlisted as a finalist in the CIPS Excellence in Procurement & Supply Awards 2026, in the Best Procurement Transformation Programme category, for a submission on moving from centralised procurement to agile global sourcing, which it linked to its internationalisation and its place in the Vulcain Engineering Group. Its accounting and finance teams visited Vulcain’s Paris headquarters on 15–17 June 2026.
