Introduction
IGS London was commissioned to investigate the repeated failure of external lighting installations at Blondin Way, Rotherhithe, after the Residents’ Association had incurred significant ongoing costs replacing lighting fittings that had become water damaged.
Rather than simply replacing failed fittings, our engineers carried out a detailed technical investigation to identify the underlying cause of the recurring failures. This approach enabled us to deliver a permanent engineered solution instead of another temporary repair.
External Lighting Remediation Project Overview
Location: Blondin Way, Rotherhithe, London
Client: Residents’ Association / Managing Agent
Services Provided:
- External lighting remediation
- Water ingress investigation
- Waterproofing improvements
- Drainage modifications
- Electrical testing and commissioning
- Long-term maintenance solution
The Original Problem
Previous contractors had repeatedly replaced failed lighting fittings without identifying the underlying cause of the failures. As a result, the management company faced an ongoing cycle of replacement costs, electrical faults, and disruption.
Our inspection identified that the lighting fittings had been installed within recessed trays that naturally collected rainwater.
Critically, the original installation had not been adequately waterproofed:
- Cable entries had not been correctly sealed.
- Waterproof glands and grommets had not been installed.
- Water was able to penetrate directly into the electrical fittings.
- The trays had no effective means of drainage, allowing standing water to accumulate around live electrical components.
Consequently, the fittings repeatedly became waterlogged, leading to:
- Premature failure of luminaires
- Electrical tripping
- Ongoing maintenance call-outs
- Repeated replacement costs
- Continued inconvenience for residents
Replacing the fittings alone would simply have resulted in the same failures occurring again.
Our Engineered Solution
Rather than treating the symptoms, IGS London addressed the root cause of the problem.
Our engineers carried out a comprehensive remediation programme that included:
- Installation of specialist waterproof glands and grommets
- Full sealing of all cable entry points
- Resealing of the recessed lighting trays to prevent water ingress
- Installation of carefully positioned drainage outlets to allow trapped rainwater to escape safely
- Electrical testing and commissioning of the completed installation
- All testing and commissioning were completed in line with recognised industry best practices for electrical safety.
As a result, the lighting system was fully protected against prolonged exposure to severe weather while preventing water from compromising the electrical installation.
The Results
The completed works transformed an installation that had suffered continual failures into a robust, long-term solution.
By identifying and rectifying the underlying design and installation issues, IGS London:
- Eliminated recurring water ingress
- Prevented repeated electrical failures
- Improved reliability during heavy rainfall
- Reduced future maintenance requirements
- Significantly extended the service life of the lighting installation
Most importantly, the Residents’ Association and management company avoided what had become an ongoing cycle of costly replacements.
Without identifying the root cause, the site would likely have continued to incur substantial annual expenditure replacing damaged fittings. Instead, IGS London delivered a permanent engineered solution that is expected to save the client many thousands of pounds over the lifetime of the installation.
