NUS Consulting has agreed a basket deal whereby some 150 companies will switch to renewable power from Smartest Energy.
The group purchasing arrangement means smaller firms that might not usually have the resource to take a flexible supply contract can do so.
Under contract, expected to be worth around £180m over four years, businesses ranging from an ice cream producer to a medical device manufacturer will be switched to 100 per cent renewable power by October 2020.
“This is the first time we have agreed a deal with a supplier in the UK for 100 per cent renewable power right across a portfolio and is a great example of how the industry is working together to support the journey to net zero,” said NUS Consulting UK general manager, Giles Lawson.
The framework runs to 2023.
