How does the BlueGreen device work?

The device regulates the voltage in the home to a steady value, typically 220V. The UK average supply is 245V and most appliances use less energy at the lower voltage. All appliances must be CE-marked and this means they will operate normally at the lower voltage. With a BlueGreen installed, your electricity bill will be between 6 and 12% lower and your appliances and light bulbs will last longer.
