Energy firms are adamant that only they can see your data and that information cannot be passed on to a third party without the customer’s explicit permission.Īccording to Octopus Energy, not even the network operator can read a customer’s electricity data as it is encrypted before it reaches them.Ī Privacy Charter drawn up by the Energy UK trade body, however, states that organisations with which your supplier has a contract may be given access to the information collected from your meter. The chief concern of smart meter critics, besides the cost, is the potential privacy concerns that come with a household’s data being transmitted to a supplier.Īlthough smart meters send meter readings to your energy supplier, they do not store your name, address or bank details. They had been popular in Europe for this reason. The policy on smart meters was first championed by former Labour leader Ed Miliband – and later by the Tories – as a way of reducing Britain's energy use. Octopus Energy, meanwhile, offers a tariff which updates rates every half an hour depending on wholesale prices, which can be a double-edged sword in periods of high volatility, though this rate is capped if it goes beyond 35p/kWh. Overnight tariffs are handy for charging electric cars, and some providers offer specific tariffs for that purpose. However, its daytime rate is higher than a standard variable tariff. Some of these deals are more complex than others: British Gas’s Economy 7 tariff, for instance, charges a lower rate overnight, which is half the cost of the daytime rate. “Time of use” tariffs drop the price of electricity when demand is low and increase it in times of high usage. Smart meter users could get cheaper energy dealsĮnergy firms are expected to introduce more smart meter tariffs that vary electricity costs throughout the day. You should contact your provider immediately if you believe your smart meter to be faulty.Īnother issue is that hardware associated with the devices will need to be upgraded in central and southern England, after the Government and mobile phone providers announced plans to phase out 2G and 3G mobile networks by 2033. In one case, a homeowner’s home display accidentally showed that he had used £40,000 worth of electricity in a single day. Though these issues should not affect new smart meter users, they are indicative of the problems that have plagued the rollout.Īnd while such stories are rare, smart meters have been known to suffer glitches, resulting in comical instances of households told they are paying tens of thousands for power. However, a loophole means providers are not obligated to do so, as the rule set by Ofgem only requires that all smart meters be operational by 2025. Households with a “dumb” smart meter can ask their supplier to replace it with a modern one. This is because some "first generation" smart meters became incompatible with the communications network and were unable to send their automatic meter readings. Some owners of early models have also received a nasty shock when they switched energy provider and their modern meter turned "dumb" – rendering it no better than a traditional meter. The smart meter rollout has been vastly expensive and repeatedly delayed. Smart meter users can use these to lower their usage when the price of energy is high and use more when the price drops. Some energy suppliers offer specialist tariffs which vary the cost of electricity throughout the day. It sends readings automatically to suppliers, meaning customers are less likely to underpay or overpay for gas and electricity. Smart meters come with a display device to track how much energy is being used more accurately. So will a smart meter help you save energy, or add to your bills? How do smart meters work? They also allow energy providers to remotely switch those who fall behind on bills over to pre-payment meters. The devices, which replace traditional meters that have to be read manually, provide real-time readings that detail how much gas and electricity you are using, and how much it is costing you.īut the rollout has been controversial, with plans afoot to use the devices to charge households more to use power at peak times, with cheaper rates available when demand is lower. Every home in the UK is being offered a smart meter in a multi-billion pound rollout that is changing the way we consume and pay for energy.
