We've built strong relationships with the operations teams, supervisors, and procurement managers who rely on us, as well as with the equipment suppliers and manufacturers behind the systems we install.
About SEC Electrical & ConstructionSpecialists in mining, industrial and renewable energy electrical work
SEC was founded because we saw a clear need in the Central West for a local electrical team that understood the realities of mining and industrial work. We are a team who know the sites, the conditions, and the pressure to keep production moving.
Our team brings more than 20 years of combined underground and surface experience across electrical maintenance, shift coverage, and site management. We’ve worked in the same environments our clients operate in, and we know what it takes to deliver safe, reliable work in high‑risk, production‑critical settings.
Being local means we’re close enough to respond quickly and invested enough to care. We’ve built strong relationships with operations teams, supervisors, and procurement managers across the region.
What sets us apart is simple: we want our clients to thrive. We care about the region, the people who work in it, and the long‑term partnerships that keep businesses growing together.
Safety, trust, and consistency aren’t just part of our process.
They’re the foundation of how we operate.

Frequently Asked Questions
-
We're based in Central West NSW and primarily service mining, energy, and industrial sites across the region. For the right project scope, we also mobilise to sites further afield. Get in touch and we'll confirm whether we can service your location.
-
Yes. We maintain 24/7 on-call availability for breakdown and emergency response. Our team is local, which means faster mobilisation than contractors based in major cities, and we're familiar with the sites and environments in the region.
-
All our electricians are qualified, site-inducted, and work to full WHS compliance including SWMS and JSA processes. We carry out thermal imaging and RCD testing as part of our standard practice, and we can supply relevant compliance documentation as part of our pre-mobilisation process.
-
Yes. We work with clients on both. Some of our client relationships are long-term maintenance arrangements with scheduled and reactive components. Others engage us for specific project or expansion scopes. We're set up to handle either, or a combination of both.
