The VPhase voltage optimisation device is well publicised as saving consumers around 10% on their home electricity bills. Its claims have been robustly tested and independently verified, with their widespread advertising ensuring this message is suitably broadcast. But how much is that 10% saving actually worth to each consumer?

If you consider the cost of buying and installing the VPhase unit as an investment, at £299 (current price from their national fulfilment partner, Eaga) then it’s a reasonably low cost investment. With average electricity bills now regularly over the £600 mark, the 10% energy saving equates to around £60 a year. A quick calculation shows that a £60 annual saving on a £299 investment is around a 20% return on investment.

There are very few investment vehicles available in today’s market that can even come close to offering that kind of return on investment. The market leading cash ISAs are offering just under 3% per annum return; and whilst it’s typically fixed for the first year, there’s no saying what it may be in subsequent years.

With energy prices continuing to increase and providing little evidence of a trend reversal, there’s every reason to project an improved return on investment, year after year with the VPhase device. The device itself comes with a 5 year warranty, and with payback periods typically less than this, it represents a virtually risk free investment.

A final thought worth contemplating is that the VPhase device has an expected life span in excess of 25 years, and with no moving parts inside it, is completely maintenance free. Saving 10% on your electricity bill right now is very desirable, as is the 20% return on investment – but just think what electricity prices will be 25 years from now and what sort of savings and return on investment could be achieved – it’s a staggering thought!
