Costs from £650+VAT, average bill reduction 12%, 5-7 year payback.

Key facts: Voltage Optimisation for homeowners

In line with CE and EU regulations, most of the UK’s electrical equipment is optimised to work at 220-230v. For historic reasons our electricity is supplied at an average of 242v but could be as high as 253v. 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 appliances.  Most electronic equipment currently consumes more electricity than it needs to….

  • Typically reduces your electricity consumption by 12%.
  • Expected payback time 5-7 years.
  • Works well with Solar PV, wind turbines and heat pumps – some solar PV systems are cutting out because of the high incoming voltage and the system owner doesn’t know about it….
  • Prolongs the life of your electronic equipment: AAA rated appliances are rated at 220V, rather than 240V. They won’t behave as AAA rated at 240V, but that may not be clear when you buy the appliance.
  • Typical savings by appliance:
  • fluorescent lights 20%;
  • hairdryer 19%;
  • vacuum cleaner 18%;
  • microwave 16%;
  • fridge/freezer 10%;
  • patio heater 15%;
  • washing machine 7%;
  • dishwasher 5%.
