our history

Starting the business
In 1994, Wayne Cramer, a young man from Sheffield with a background in electrical engineering and a passion for manufacturing excellence, founded GWE in his hometown.
The Journey
From its early days 30 years ago as a tiny business in a 2,000 square foot unit, to where it is today, has been an exciting and inspiring journey.
Energy Saving Movement
Soon after starting the business, Wayne recognised the importance of the energy saving movement, leading GWE to become the original UK manufacturer of VO.
Saving money and CO2
The technology has since saved thousands of organisations huge amounts of money and hundreds of thousands of tonnes of CO2.

Saving the planet
For over three decades, GWE has supplied their planet saving technology to countless businesses who want to save money and protect the planet.
A fresh approach
Now in its 30th year, the same business Wayne started has chosen a fresh brand which reflects its push to net zero for all, captured in its new name, Zeron.
