What we do
We survey. We design. We build. We energise. We maintain.
Most power projects in Nigeria don't fail on engineering. They stall between contractors. One firm chases the approvals, another brings the transformer, a third strings the line, and nobody owns the switch-on date.
We do all of it. One contract, one number to call, and one team that answers for the result, from the first site visit to the day your load is running on clean, stable power.

Who we are
Engineers, linemen, planners and problem-solvers.
Ionir Integral started in 2007 as Glincor Tech, a handful of engineers fixing power problems for telecom operators in Lagos. Today we run multi-site programmes for some of the biggest tower companies in the country. We still pick up the phone ourselves.
Our crews are trained, insured and properly kitted. We work under permit-to-work, we test before we energise, and we photograph every stage. That's how you earn repeat work from clients who can't always be on site.
