Illuminated Assets: Preparing for PFI Expiry With Accurate Testing and Data Collection

Introduction

With a significant wave of street lighting PFI contracts reaching expiry over the next decade, many local authorities and service providers face a major challenge: ensuring that illuminated assets are safe, compliant and accurately recorded before hand‑back. Structural & electrical testing alongside data collection play a crucial role in building a clear understanding of asset condition and remaining useful life.

Executive Summary

PFI expiry requires the transfer of safe, compliant and accurately documented illuminated assets. Kiwa CMT supports this with UKAS‑accredited structural testing, new periodic electrical testing, GN22‑aligned data collection and nationwide survey capability. Acting early reduces risk, avoids penalties and supports evidence‑based asset management.

Why PFI Expiry Poses a Challenge for Street Lighting

Private Finance Initiative contracts were designed to modernise and maintain street lighting by transferring financial and operational risks to private partners. As these 20–30 year contracts come to an end, the responsibility for compliant assets returns to local authorities.

Many organisations are discovering they lack the accurate, complete and up‑to‑date information required to manage a smooth hand‑back. This can expose them to avoidable risk, cost and reputational pressure.

Why Accurate Inventory Data Matters

In practice, Kiwa CMT regularly identifies:

  • Assets recorded in inventories that no longer exist
  • Incorrect material types (e.g., steel columns logged as concrete)
  • Non‑conformities that were not visible from ground level
  • Missing, outdated or incomplete positional and electrical information

Reliable data forms the foundation of every asset management plan.

The Role of Illuminated Asset Testing

    Structural Testing (RLS System)

    Kiwa CMT’s UKAS‑accredited structural testing uses the unique Relative Loss of Section (RLS™) system to detect below‑ground or internal corrosion in steel lighting columns. This technique identifies hidden degradation - including at the base and swaged joints - that visual inspection alone cannot reveal. Columns are categorised with clear recommendations for re‑test or replacement.

    Periodic Electrical Testing (New for 2026)

    Kiwa CMT has introduced periodic electrical testing for lighting columns, expanding its service into a complete structural, electrical and data capture solution. Fully trained HERS technicians test electrical safety in line with BS 7671:2018 and the Health and Safety at Work Act, helping duty‑holders maintain compliance and reduce risk.

    Inventory Data Collection and GN22 Compliance

    Accurate, GN22‑aligned data collection ensures every asset is correctly positioned, recorded and profiled. Technicians use handheld GPS equipment to capture data for direct upload to client systems, supporting LED conversion projects and ongoing maintenance planning.

Common Issues Found During Asset Surveys

Drawing on thousands of annual inspections, Kiwa CMT frequently uncovers:

  • Missing or duplicated assets in inventories
  • Incorrect material profiles affecting contract compliance
  • Early‑stage corrosion not visible at the surface
  • Electrical defects requiring immediate attention
  • Attachments installed without structural verification (e.g., festive decorations, CCTV, banners)

These issues can materially affect hand‑back valuations, liability, and programme planning.

Frequently Asked Questions

What is an illuminated asset?

An illuminated asset includes street lighting columns, illuminated signs and bollards that require structural, electrical and data assessment.

Why is PFI expiry significant for street lighting?

PFI expiry transfers responsibility back to local authorities, requiring assets to be safe, compliant and accurately recorded.

How often should lighting columns be tested?

Testing intervals depend on column condition and GN22 classifications, ranging from 1–5 years.

What does the RLS system detect?

RLS identifies below‑ground and internal corrosion that cannot be seen through visual inspection.

Why is electrical testing required?

Periodic electrical testing is a legal requirement and ensures compliance with BS 7671:2018 and reduces risk of electrical faults.

Can Kiwa CMT provide both structural and electrical testing?

Yes. Kiwa CMT now offers a complete suite including structural, electrical and data capture services.
