The National Grid delivers, on average, 242 volts to all UK users. With voltage optimised, electrical equipment works at optimum cost efficiency at 220 volts. All supply above 220v is waste.
Through Ohm’s law, optimising voltage on any supply produces instant kWh savings of up to 19%, which will give an instant reduction in electricity bills and carbon footprint. In addition, and as confirmed by the UK’s wiring regulations (BS7671), any electrical equipment required to work at 242v, will suffer a reduced working life by up to 46%.
We guarantee to reduce your voltage by between 6% and 10%.
