Across Europe the agreed statutory range for voltage is 207V to 253V. In the UK voltage is typically around 245V. Household appliances must be designed to operate satisfactorily within the European statutory range. Many of the appliances we use regularly will use less energy at lower voltages. VPhase has developed a new innovative and unique smart technology that enables Voltage Optimisation to be cost effectively introduced into the home. The VPhase unit reduces and stabilises the voltage at the property to a level within statutory limits but below the voltage that is usually supplied by power companies, in the UK the VPhase output is typically 220V.
