A new bill tariff has been proposed that could see customers paying more for using electricity when demand is higher.
This type of billing is known as 'surge pricing' and according to the Telegraph, three major energy companies are backing plans for it to be introduced if you use a smart meter.
Scottish Power, EDF and Octopus Energy are supporting 'surge pricing' for energy bills. The scheme that uses smart meters charges you more to watch TV or make a cup of tea at certain times when demand is high, for example in the morning.
