Perrys Motor Dealer


Established in 1908, Perrys is a leading motor dealer whom represent a number of high calibre brands including Vauxhall, Peugeot, and Jaguar to name only a few.

Perrys actively encourage the use of carbon friendly cars as a method of reducing environmental impact and also strive to reduce their own carbon footprint as a car dealership business.


Originally starting out as a motor accessory supplier, Perrys has since evolved to deal with a growing number of motor brands across 24 dealership locations and are one of the largest network of Vauxhall dealers.


Perrys is keen to adapt to meet the socio-economic demands associated with their industry and actively seek initiatives to lower their carbon footprint and reduce their energy spend.

Eager to benefit from reduced energy consumption, Perrys rolled out an Energy Management programme across their whole network, ensuring they achieved maximum impact and benefits.


As part of a wider energy management project, Perrys had their gas and electricity consumption patterns monitored and carried out audits at each site; analysing advice and recommendations on how they could reduce utility consumption.

Perrys concluded that voltage optimisation technology would provide additional savings beyond measures already actioned, to offer the most catered solution for the Aylesbury branch’s high energy consumption patterns.

Perrys felt confident that Powerstar would rectify their high energy consumption, lower their carbon footprint, and reduce their electricity costs.


The installation of Powerstar at Perrys Aylesbury branch was carried out on 3rd October 2012.

Through the acclaimed project management approach adopted by EMSc (UK) Ltd, Perrys experienced a seamless installation with no disruption to business operations.

Pre install, Perrys previous annual energy load was 492,710 kWh, post install, this is set to reduce by 39,417 kWh per annum.

Powerstar has delivered energy savings of 8%, above the guaranteed savings of 7.6%.
