Waitrose, Iceland, the British Retail Consortium and energy giant Npower are the latest major organisations to throw their weight behind The Grocer’s Switch the Lights campaign, which aims to accelerate the use of LED lights across UK retail.

Waitrose development director Nigel Keen said LED offered retailers the chance to make a difference to a “key environmental issue” and that the supermarket “fully supports” the campaign.

A spokesman for Iceland said the frozen foods specialist was “delighted to support a campaign that will be good for both business and the environment,” and that it planned to make its 850 stores 100% LED by 2018.

Wayne Mitchell, head of industrial & commercial at Npower, said: “The Grocer’s campaign hit on an important point about energy efficiency: even a small change can result in huge benefits for the environment and the retailer.”

Helen Dickinson, director general of the BRC, added that the campaign highlighted the “pivotal role” LED could play in reducing energy use and cost, as well as making a “key contribution to energy security and climate change mitigation.”
