A unique and specialist approach to the utilities sector.

Critical Infrastructure Maintenance is the specialist provision of access and repair services for remote and hazardous utility assets, including power stations, water treatment works, and telecommunications masts. It requires advanced safety accreditation for working in high-voltage, chemical, or biological hazard zones where standard access equipment cannot be used.

Accessing the Inaccessible

We go where others can’t. Utility sites are often remote, unmanned, or physically difficult to access. NSS provides a self-delivered access solution. Whether it’s a remote wind turbine, a substation roof, or a water tower, we deploy our own 4×4 capable truck mounts and specialist rope access teams.

We do not rely on third-party hire, meaning we can guarantee response times even to the most isolated grid locations.

Safety & Regulatory Compliance In utilities, compliance is binary: you are either safe, or you are off-site.

  • EUSR (Energy & Utility Skills Register): Our operatives carry appropriate EUSR cards for water and power sites, ensuring they understand the specific site risks before arrival.

  • Confined Space Entry: We have specialist teams trained for Confined Space work, essential for accessing culverts, tanks, and underground utility assets.

  • Fall Arrest Testing: We inspect and certify the safety systems (ladders, eyebolts, lifelines) that your own engineers rely on to climb towers and chimneys.

Remote Asset Integrity Remote Asset Integrity ensures that unmanned infrastructure remains operational without constant human presence.

NSS Monitoring: We conduct drone surveys and physical inspections of remote assets to identify structural issues, such as concrete spalling on water towers or corrosion on pylons, before they become critical failures.

Core Utility Services

  • Difficult Access: Rope access and all-terrain MEWPs for remote site maintenance.

  • Safety Systems: Testing and installation of fall arrest systems for pylons and towers.

  • Industrial Cleaning: Heavy-duty cleaning for water treatment tanks and plant rooms.

  • Vegetation Management: Clearance around remote assets to prevent fire risk and access blocking.
