What Onnec does
Onnec is a privately held UK-headquartered IT infrastructure integrator founded in 1995, delivering design, installation, procurement, project management and operational support for enterprise connectivity and data-centre environments. The company operates four core service lines — Structured Cabling, Data Centre Solutions, Network Solutions, and Support Services — covering the full lifecycle of physical and logical infrastructure for hyperscalers, cloud providers, enterprise office estates, fulfilment centres, and logistics operators across 120 cities in EMEA, the US and APAC.
Onnec's technical differentiation rests on off-site prefabrication of network components (pre-terminated cabling, rack systems, containment) which delivers approximately 20% time savings versus on-site build, specialist capability in high-density AI infrastructure deployment including liquid cooling integration and InfiniBand networking, and — following its June 2026 acquisition of Danish specialist GI-NetWorks — Data Centre Infrastructure Management (DCIM) expertise that strengthens its managed-service portfolio. The company holds premier vendor partner status with CommScope (first Pan-European Elite Partner) and Fortinet (Operation Partner of the Year), and maintains a dense certification stack covering ISO 9001, ISO 27001, ISO 14001, Cyber Essentials Plus, CHAS Elite and Achilles Silver Plus that pre-qualifies it for enterprise and regulated-customer bids.
The business model combines project-based professional services (design, installation, procurement) with recurring managed services (on-site maintenance, urgent fixes, network optimisation). Revenue is generated through custom enterprise contracts rather than standardised pricing, sold via a direct enterprise field-sales motion structured around key global accounts — some spanning more than 30 years — supported by thought-leadership content, industry events and an active LinkedIn presence. Onnec serves approximately 105 organisations globally and has completed over 3,000 projects, with no disclosed external funding rounds and ownership that appears to be founder/management-held.
