Householdsers could save millions of pounds on energy bills by using a meter capable of telling you how much your kettle costs to run. The Energy Saving Trust, which offers impartial energy advice claims Ealing residents could save £5.3m in energy bills each year with the installation of a Smart Meter. The trust wants the Government to put pressure on energy suppliers to offer their customers the meters, which show consumers the how much energy appliances in their house use, and what it costs. The trust’s research suggests eight out of ten people do not know what they are paying for gas and electricity. The meters would cost around £100 to £200 if mass produced. The trust says trials of the Smart Meter have shown they can reduce bills between five and 10 per cent.
