LED lighting upgrades in Isleworth
What we do in Isleworth: swap fluorescent, halogen and metal halide fittings for efficient LED. Old tubes are hazardous waste. Our teams working in Isleworth bag and recycle them through an authorised route and give you the paperwork.

Local LED lighting upgrades in Isleworth
Most Isleworth businesses we survey still have a mix of T8 battens, 600×600 fluorescent panels and the odd halogen downlight. Replacing them with complete LED luminaires usually cuts lighting energy by a third to a half.
Where ceilings in Isleworth offices are being replaced anyway, we plan the new LED layout to BS EN 12464-1 rather than simply copying the old positions.
For Isleworth premises we plan works around opening hours, deliveries and shared access, which matters on mixed-use estates and high streets.
