In one case, the reading was out by 582 per cent, a massive discrepancy. This despite the meters in the test being fully certified.
The irony here is that the errors are caused by people using new, energy-saving light bulbs, LED lamps and dimmers in their homes.
In their testing, the researchers found that fast-switching devices distort the normally smooth 50 Hertz sine wave of the power supply.
Instead, the wave takes an erratic shape and that's something electronic meter designers have not made allowances for.
