Tesco has unveiled its latest eco weapon – its first all-LED store (almost).

The retail giant said all external signage at the new Express store in Loughborough, as well as lighting on the sales floor and in staff areas, is made up of energy-efficient LED fittings.

The store’s cold rooms, fridges and freezers are also lit by LEDs, with the only place in-store where standard lighting is retained is the bakery oven, as the temperature is too high for LEDs to function.

Tesco expects the LED lighting to produce a 30% energy saving.

“We have recognised that through the use of LED light fittings we can dramatically reduce energy usage, particularly at Express stores due to their smaller size and lower ceiling height,” said Emmily Sjolander, environmental programme manager at Tesco.

“If this delivers the energy savings we have estimated, it is likely that we would replicate this lighting system at other stores.”
