Evelina London Children’s Hospital, part of the Guys and St Thomas’ Hospital Trust, required a full lighting upgrade across all seven floors of their building, covering a wide range of clinical, operational and public environments. The Trust wanted to improve energy performance, reduce the amount of ongoing maintenance and simplify emergency lighting compliance. They also wanted to create a future-ready lighting infrastructure able to adapt to changing operational needs.
Working alongside the main contractor Solarcrown Commercial, with the project procured through the ProcurePlus framework, the brief was to deliver financial and carbon savings while giving the estates team greater visibility and control of the lighting.
To meet these objectives, we delivered a fully intelligent lighting solution including design, manufacture and commissioning support. Across the seven floors, our lighting was developed as a networked system rather than operating as standalone fittings to transform what is normally a passive utility into an actively managed building system.
Alongside the installation of new luminaires, several existing wall lights were retained at the request of the hospital team. Instead of replacing them, we manufactured bespoke retrofit gear trays incorporating modern LED boards, drivers and integrated controls. This approach extended asset life, reduced material waste and ensured those fittings became part of the intelligent network rather than isolated legacy units.
The scheme was unified through mymesh wireless controls, creating a secure, building-wide lighting network. This enabled:
Dimmable lighting across clinical and public areas
Flexible zoning without additional cabling
Remote configuration and adjustment
Performance, usage and fault data
Integrated emergency monitoring
Emergency lighting was fully incorporated into the intelligent system, allowing automated testing, centralised reporting and accurate fault identification. Instead of relying on manual checks and spreadsheets, the estates team now has clear visibility of system status and compliance performance across all seven floors.
By combining efficient LED technology with intelligent control strategies, the project delivered substantial operational benefits alongside energy reduction.
Results
Year 1 electricity savings: 80%
Return on investment: 3.75 years
Year one carbon savings: 240 tonnes of CO₂
