The VO4 voltage optimisation systems optimise the whole premises which leads to bigger savings than other voltage optimisers that work on selected circuits. The system does not require you having to change your consumer unit.
Installation of the any of the VO4 range of single phase or three phase units must be carried out by a qualified electrician. The installation is very simple and will not affect the existing circuitry in your premises.
As long as the VO4 voltage optimisation system has been correctly installed by a qualified electrician we will guarantee the unit for a period of 5 years against defects in manufacture. This guarantee does not affect your statutory rights.
