Homeowners living in Merton in south-west London may be encouraged to switch energy companies if they choose to borrow an Owl smart meter.
The devices are being provided free of charge during Energy Saving Week to help local residents identify their energy usage and see where savings can be made, reports the Daily Mail.
People are advised that using energy-saving light bulbs can save £40 in the long-term, while those with more to invest could save as much as much as £200 a year by installing a condensing boiler or by using domestic insulation.
According to the Energy Saving Trust, homeowners spend around £1,200 every year on energy bills and with prices set to rise even further in the coming years reducing usage through more efficient practices could help more people pursue cheap energy rates.
The government plans to spend nearly £10 billion rolling out millions of smart meters over the next decade, which could help lower bills by producing more accurate billing and raising greater awareness of usage.
