Costs from £510+VAT, average bill reduction 12%, 4-7 year payback.
In line with CE and EU regulations, most of the UK’s electrical equipment is optimised to work at 220-230v. For historic reasons our electricity is supplied at an average of 242v but could be as high as 253v. It is a little known fact that the more voltage you apply to an appliance the more energy it consumes – costing you more and shortening the life of the device.
By matching your voltage supply to piece of equipment it is possible to make a substantial energy saving and prolong the life of appliances. Most electronic equipment currently consumes more electricity than it needs to….
The house has an average incoming voltage of 242v, and an annual load (pre-voltage optimisation) of 6,000 kWh. Overall the system saves 700kWh per annum, being just under 12% of annual usage. At a cost of just over 14p per kWh, that's a reduction in the bill of £100 per annum.

We install the Eco-Max system for several reasons:
How much does it cost?
A voltage optimiser typically has an installed cost in the order of £510+VAT, so £612 inc VAT. Depending on the level of your voltage, you can expect to make a 10% saving on your electricity bill. So if you are spending £1500 a year, that's a saving of £150. So the system will pay for itself in just over 4 years. With a small bill of around £800 a year, the payback time will be more like 7.5 years. The voltage optimiser is warranted for 10 years and will last 20-30 years.
All projects are managed in house and installed by our solar panel installers.
