“How much could we actually save?”
It’s one of the most common questions businesses ask… especially as energy costs continue to rise. The answer varies, but savings are often far bigger than expected.
Many UK commercial buildings still use:
-
fluorescent lighting
-
metal halide fittings
-
or early-generation LEDs installed years ago
Upgrading these systems to modern LEDs typically delivers 30–60% energy savings.
But for most buildings, that’s only the first layer.
The real gains come from how lighting is controlled.
Smart lighting systems introduce:
-
occupancy-based control
-
daylight harvesting
-
zoning and scheduling
-
real-time monitoring
When LEDs are paired with intelligent controls, total savings of 70–90% are increasingly common, particularly in buildings with long operating hours.
A common assumption is:
“We’ve already switched to LED, so we’re fine.”
In reality, many LED systems:
-
run at full output all day
-
light empty spaces
-
don’t respond to daylight
-
provide no visibility of usage patterns
The fittings may be efficient… the system often isn’t.
While every site is different, many businesses see:
-
£5,000–£20,000+ annual savings
-
ROI in 12–36 months
-
lower maintenance costs
-
improved working conditions
These results are increasingly typical when lighting is designed strategically.
The only way to know is to understand how your building actually uses lighting.
A proper lighting review shows:
-
where energy is being wasted
-
what savings are realistic
-
which upgrades make sense
No pressure. Just clarity.
