Sectors · 4 min
LED retrofit for schools and education
Schools and colleges use LED retrofit to cut energy costs, improve classroom light and reduce carbon across estates without replacing every fitting.
Controls · 4 min
Adding sensors and controls during a retrofit
A retrofit is the ideal moment to add presence and daylight sensors or wireless controls, multiplying energy savings without new wiring.
Design · 4 min
Upgrading diffusers during a retrofit
Replacing yellowed or damaged diffusers during a retrofit improves appearance, light quality and glare control while keeping the original fitting bodies.
Guide · 4 min
Retrofitting modular ceiling panels to LED
Modular fittings in grid ceilings can be retrofitted with new LED inserts and diffusers, upgrading light without disturbing the ceiling.
Guide · 4 min
Retrofitting suspended linear fittings
Suspended linear fittings can be refurbished with new LED engines, drivers and diffusers, keeping their design while improving efficiency.
Guide · 4 min
Retrofitting bespoke and feature luminaires
Specially made and feature luminaires that suit the interior can be retrofitted to LED, keeping their character while cutting energy use.
Sustainability · 4 min
Disposing of old lighting responsibly
Old lamps, ballasts and luminaires should be disposed of through WEEE-compliant recycling routes, and retrofit reduces how much needs disposal.
Buying · 4 min
Understanding LED retrofit payback
Retrofit payback depends on existing wattage, LED wattage, hours of use, energy prices and controls; high-use spaces usually pay back fastest.
Process · 4 min
Why a lighting survey comes before a retrofit
A lighting survey records existing fittings, condition, quantities and light levels so a retrofit can be scoped, priced and prioritised accurately.
Compliance · 4 min
Upgrading emergency lighting in a retrofit
Emergency fittings can be reviewed and upgraded alongside a retrofit, ensuring escape lighting still meets BS 5266-1 after the change to LED.
Sustainability · 5 min
Lighting's role in net zero buildings
Lighting supports net zero through efficient LED, smart controls, daylight use and lower embodied carbon from retrofit and longer-lasting fittings.
Sustainability · 4 min
Lighting upgrades and ESG reporting
Lighting upgrades give measurable energy and carbon reductions that support ESG reporting, and retrofit adds a clear waste-reduction story.
