Lighting

Approximately 40% of all energy consumed in the workplace is used for lighting. You can cut your lighting bill and energy use by changing which bulbs you use and how you use them.

There are two main types of energy efficient light bulbs available in the UK. Compact fluorescent lamps (CFLs) and light emitting diodes (LEDs). Traditional incandescent bulbs are extremely inefficient and were banned in the UK in 2009. Halogen bulbs were also banned in 2018 as they use far more energy than their low energy counterparts.

CFLs use 60%-80% less energy than traditional incandescent light bulbs but LEDs use 90% less. So while both are cost effective, LEDs are the most energy-efficient option.

Originally the cost of LED lighting was comparatively high but prices have come down a lot over the last few years, meaning this option now offers the best value for money. Replacing a single halogen light bulb with an LED of the same brightness will save you up to £2 per year.

In addition to changing your light bulbs you could save more money off your lighting bill by fitting zonal controls and light sensors which automatically turn lights on or off, depending on occupancy. These sensors work well in areas that are not occupied continuously.
