Figures from the energy watchdog Ofgem, state that people could save over £100 a year by switching gas and electricity supplier, which would almost cover the cost of household spending on energy efficient products.
Among the items included in the list of energy-efficient products were boilers, light bulbs and batteries. Switching to energy-efficient products can lead to cheaper gas and electricity bills, as well as reducing carbon emissions.
Tim Franklin, chief operating officer at the Co-operative Bank, said: "In order for the UK to reduce its carbon emissions by 30 per cent by 2020 there will need to be a step-change in take-up of low-carbon technologies, and this will need a new contract between business, government and the consumer."
Mr Franklin said that the results provided evidence that the UK was working towards a greener lifestyle.
