Moor House is a prominent 21-storey building in the City of London, standing 85 metres tall and home to leading global financial tenants. With over 1,600 people working there daily, ensuring operational safety and energy efficiency is a top priority.
When Moor House Management Services (MHMS) approached Skanska to replace halogen lift car lighting with modern LED lamps, they chose GCL as the delivery partner. With a track record of safe, time-sensitive work, GCL was entrusted with this high-risk project—completing it in a single weekend.
The lift lighting upgrade needed to:
Be completed over one weekend with zero disruption to operations
Save long-term energy costs and reduce carbon output
Maintain the existing colour rendering to match building aesthetics
Avoid any bespoke changes to existing luminaire housing
Navigate access to lift cars and car park lifts safely and efficiently
GCL faced several challenges on this project, including:
Coordinating work in a 24-hour building without interfering with operations
Accessing and working on top of moving lift cars, which required advanced safety measures
Conducting full surveys of existing systems in tight, enclosed spaces
Minimising the need for specialist engineers on-site
Despite the scale and complexity, GCL completed all work safely and ahead of schedule.
GCL developed a fast, pre-planned strategy that reduced onsite time and ensured a safe working environment. The solution included:
Prewiring LED light kits and preparing installation off-site to speed up delivery
Applying strict health and safety protocols throughout
Sourcing 10W energy-saving LED lamps to replace 50W halogens
Reducing lift lighting energy consumption by 55%
Adapting the existing emergency lighting system from central to local battery power
Retaining the same colour rendering to preserve interior consistency
GCL’s proactive planning allowed the project to be completed in one third of the typical time.
Moor House benefitted from:
Reduced lift energy consumption from 50W to 10W per unit
Minimal future maintenance thanks to long-life LEDs
Full project completion within a single weekend
Continued tenant safety throughout the process
A strong return on investment and immediate cost savings
