Distribution Network Operator (DNO)

Our team is skilled in managing the technical and logistical challenges that come with DNO interface works. From initial feasibility studies through to final install, we work closely with the network operators to coordinate connections, diversions, and reinforcement works in line with programme and budget requirements.

For infrastructure projects, minimising disruption is critical. We plan and deliver DNO upgrades in a way that keeps essential services running, protects public safety, and integrates seamlessly with wider construction activities.

Our expertise includes:

• Securing additional network capacity for major infrastructure schemes

• Delivering power connections and reinforcement works for rail depots, highways, and public sector projects

• Managing substation installations, cabling, and switchgear upgrades

• Align works with tight programme milestones

By combining technical expertise with strong working relationships across the utility sector, Cairn Cross ensures that DNO upgrades are not a constraint but an enabler for successful infrastructure delivery.
