Why buy a LENERGY

Voltage Optimiser

Our products are designed and built, manufactured in Sheffield, come with a Made in Sheffield stamp, BSI accredited and come with a manufacturers 10 year guarantee, therefore you can be secure in the knowledge that the unit is built to the highest standards and is delivered to any home free of charge in the UK directly from our manufacturers.


Why buy a LENERGY Voltage Optimiser for my home?

The reason that Voltage Optimisation is required for most homes is that in line with CE regulations, almost all of the UK’s home use electrical equipment (and Commercial equipment) is designed to operate most efficiently at 220-230v but the National Grid can supply power at a much higher rate and on average that is 242v but can be as high as 253v, costing you money and lessening the lifespan of your home electrical equipment . It is a little known fact that the more voltage you apply to an appliance the more energy it consumes – costing you more and shortening the life of the device. By matching your voltage supply to piece of equipment it is possible to make a substantial energy saving and prolong the life of your household appliances. This not only saves money but also protects and increases the lifespan of equipment such as light bulbs, tv, washing machines etc. A Voltage Optimiser can be installed in around an hour by an electrical contractor. These are also suitable for small businesses which are on single phase supply, a Voltage Optimiser will reduce any excess voltage leaving you with lower bills and lengthening the life of your electrical appliances. We also have an extensive range of Commercial 3 phase voltage optimisers for use in schools, retail, industry, leisure. It can be used in any building that receives an electricity supply. Please contact us for more information.
