How it Works


The UK electricity distribution network operates at a nominal 230V, although in practice average voltages are more likely to range between 240V and 245V. The VPhase unit manages voltage to a stable level, normally 220V in the UK, regardless of the incoming supply voltage.

The amount of energy saved is device specific, for example: testing by VPhase on fridges and freezers shows 17%, 15% on normal light bulbs and 10% on energy saving light bulbs. One digital cordless phone showed an extraordinary saving of 44%. Savings will vary dependent incoming voltage and individual devices.

Further savings can be made on washing machines, tumble driers, dishwashers, televisions and numerous other electrical appliances across the whole house.

Typically, whole house savings are in the region of up to 12% - which means, household electricity bills will be around 10% less each year.

Unlike Smart Meters, which require a change in lifestyle, or solar and wind power that are focused on renewable energy production as opposed to preventing energy waste, VPhase Voltage Optimisation is a fit and forget solution that once installed will operate silently and unobtrusively, lowering and stabilising household voltage, saving money, reducing CO2 emissions and preventing energy waste.

We’ve included more information in our FAQs section that will hopefully explain the technology and its application further and we also have a range of technical information available in our Trade Zone

Improve your Home
Fitting a VPhase unit should improve the overall energy efficiency of your home. Voltage Optimisation will work throughout the day to lower and regulate the voltage coming in to your house, resulting in reduced energy consumption, fewer carbon emissions and lower electricity bills.Whilst the VPhase does not currently contribute to EPCs, we are seeking inclusion as a priority. Despite this, cutting up to 12% off your electricity bills is not something to be overlooked.
With all electrical devices and appliances having to work across the EU range of voltage (207V to 253V) since the early 90s, many appliances will actually work more efficiently at the stable, lower 220V that the VPhase typically optimises to – meaning greater efficiencies and potentially prolonging the life of your electrical equipment.
