Welcome to the GW Energy website.

We specialise in energy savings for a wide range of premises. We combine voltage optimisation with other technologies to provide the highest levels of energy savings possible, dependent on site specific issues.


Bespoke Power Optimisation

In the UK supply voltages tend to be much higher than needed by most equipment, wasting energy, and shortening the working life of some equipment. Our ECO-MAX range of Bespoke Voltage Optimisers solve this problem and can also improve power quality when we build in Power Factor Correction or Harmonic Filtration for example.

GWE can provide a basic whole site ECO-MAX Voltage Optimisation unit, similar to our competitors offer, however our unique engineered approach and detailed site surveying will normally enable us to provide a more localised approach, tailoring bespoke equipment specific to your site, and only applied to the areas where substantial savings can be made.


Contractor Range of Voltage Optimisers

On a smaller scale, GWE have also recently launched The ECO-MAX Contractor Range, comprising of The ECO-MAX-HOME single phase and The ECO-MAX-COMMERCIAL three phase 'off the shelf' Voltage Optimiser systems for smaller sites and areas, including houses and homes. These are now available through good Electrical Wholesalers.

Please take a look around the site and download our information for more details on our ECO-MAX Voltage Optimiser systems.


Lighting Optimisation & Low Energy Lighting

Although GWE focus mainly on Power Optimisation, where our localised approach and detailed surveying identifies large areas of discharge lighting, typically found in warehousing/ distribution, and manufacturing etc, our ECO-MAX Lighting Optimisers can be offered. These again are comprehensive lighting control systems incorporating technologies such as daylight dimming etc.combined with our voltage optimiser. Our solutions provide lighting energy savings of between 20% and 80% without changing any fittings. This is probably why we are the number one choice for large facilities operating long hours, such as Amazon, Asda, and Sainsbury’s distribution centres, where payback tends to be within 1 year.

New Facilities.

Our new larger facilities incorporate a large training room and meeting rooms which will allow us to host training on GWE solutions for our customers. Situated in Sheffield we have a central location, contact us if you would like to enquire about our training and meeting room facilities.


Expanding Horizons.

GWE continue to expand its horizons, increasing its Eco-Max awareness into other countries. Our flexibility and bespoke solutions alongside our continuing strong relationships with leading distributor channels allows continued increases in sales.
