From the MV connection to building installations — one contractor.
On the market since 1997. From a local installer we grew into the partner that general contractors and investors trust with the entire electrical trade on site — without splitting the scope between several firms.
We work mainly in Silesia and deliver projects across Poland and abroad — building installations, MV/LV power networks, telecoms and automation. One team, full scope: from design, through cross-trade coordination, to handover and as-built documentation.
- One contract for the whole trade — no scope split across subcontractors
- In-house SEP-certified team — 20+ specialists, categories E and D
- Handover and documentation — measurements, protocols, as-built documentation
Who we work for
Four client groups — from large industrial and commercial investments to selected private projects.
Building and business investors
Production halls, plants, office buildings, logistics centres and housing estates. The complete electrical trade from one contractor — MV and LV connections, building installations, documentation and handover for the occupancy permit.
General contractors
Electrical and network subcontracting on large sites. An in-house team of 20+ SEP-certified specialists, heavy equipment, cross-trade coordination and work to the contract schedule.
Public institutions
Hospitals, universities, schools and sports facilities — delivered under public procurement, with a complete handover documentation set. Our clients include AWF Katowice and the Silesian Centre for Heart Diseases in Zabrze.
Individual clients
Selected private investments with a broad scope — high-standard houses, service connections, photovoltaics with energy storage. Smaller jobs are taken on subject to team availability.
