Our customers

We like to feature some of the businesses that have made the switch to green energy uk and their reasons for doing so. We hope that you enjoy reading about them.


WISER is an independent group of companies established in 1999, with a Head Office in St Ives, Cambridgeshire, and offices and facilities in Huddersfield, West Yorkshire and Thetford, Norfolk.

The Group consists of WISER Environment, an environmental consultancy, and WISER Recycling specialising in innovative collection and recycling of waste electrical and electronic equipment (WEEE).

The core business of WISER Recycling is the recycling of waste fluorescent tubes using an on site crushing device called the TubeEater which reduces waste volume and eases transport. All waste fluorescent tubes are sent to the WISER treatment plant which separates out the component parts and produces the highest quality glass cullet in the UK. This is then sold back to lamp manufacturers and ‘closes the loop’ on the fluorescent tube life cycle. The hazardous mercury is safely separated and recovered and metal components are sent for recycling.

Already running its treatment plant directly from waste cooking oil, WISER turned to green energy uk in order to supply 100% of its energy needs for its Head Office activities from renewable sources. Managing Director Russell Hirst said “Our environmental consultancy has an energy consultant. He recommended green energy uk to me. The service we have received has been excellent and I also like the fact that we can deal directly with a company with a similar view on the environment and quality of service as our own.”
