About us

Built on outcomes, not overheads.

Our story

We've been here since 2017.

Cornerstone Services Group is the evolution of Cornerstone Electrical, the licensed electrical contractor at the centre of the business. Since 2017, 650-plus projects across education, healthcare, commercial buildings and civil infrastructure have built the reputation. The group is what happened when clients kept asking us to stay involved beyond installation.

That demand shaped the model:

  • Design and Construct delivery
  • Planned maintenance and rapid fault response
  • Multi-site programmes and coordinated shutdowns
  • Electrification, EV infrastructure, energy monitoring and power resilience next

It has grown without blurring licence responsibilities. Our team delivers electrical, data and communications, Facilities & Service and electrical compliance. Specialist partners deliver HVAC, fire protection and security under our project management, with one programme and one point of responsibility.

Cornerstone Services Group is a proud business of Cornerstone Group. Alongside Cornerstone Construction, we share the same commitment to quality delivery, strong client relationships and creating thriving communities.

Our values

How we work, on every site.

Four values from our team charter. See what they mean for our people.

  • Safety First

    Protecting our people, our clients and our community, always.

  • Excellence in Delivery

    Client-led, delivery-focused.

  • Integrity & Accountability

    We own our work, and we stand behind it.

  • Leadership Through Commitment

    Lead with courage, innovate with intent, and win together.

Build to maintain

Handover is not the finish line.

When the same team carries project records and as-built knowledge into ongoing service, faults can be investigated with better information and maintenance can be planned around the actual asset. Our model connects construction, compliance and service so clients are not starting again with a new contractor at every stage.
