King Edward VI College Stourbridge






A specialist sixth-form college with more that 2,000 full-time students aged 16-19. The college provides a full range of academic courses including arts, business, mathematics, and science-related subjects


The college acknowledged that its energy usage was higher than the typical benchmark average for education facilities in the UK. As a result the management team sought a solution that would improve energy efficiency, reduce the overall cost of electricity and cut the carbon footprint. Voltage optimisation was identified as a key technology and numerous options were evaluated to determine which solution offered the most effective results, and best value for money.


Powerstar impressed the college due to the open, honest and professional approach. Clear lines of communication were kept open at all times and several visits were undertaken by Powerstar engineers to ensure the best solution was specified. The 100% savings guarantee reassured the King Edward VI college management team that Powerstar was the best solution to implement.


The installation was completed with no disruption to the college activities. The post-install customer service was singled out for praise by the college who described it as ‘excellent

The goal of the sustainability program was

Energy Saving & Saving Money

which was achieved with no disruption to the college activities

Customer Testimonial

As part of our sustainability programme we targeted electricity supply as an area where efficiencies could be saved and cost savings made. The aim of installing the voltage optimisation system was to save money and energy whilst boosting efficiency. I have no hesitation in recommending Powerstar to any interested party.
