Major energy supplier Npower is funding a new scheme launched by the National Trust to show how residents of older homes can pursue energy efficiency.
Npower is providing £600,000 to fund the scheme that will focus on how houses built in the 1750s and the 1850s in Coleshill, Oxfordshire and the Wallington Estate, Northumberland, can boost their efficiency to lower carbon emissions and energy bills.
Residents will choose which energy-efficient plans to follow, with measures such as sheep's wool being suggested for use an insulation material.
Celia Robbins, the National Trust's project manager at Wallington, said: "Installing sheep's wool loft insulation and improving the efficiency of off-grid electricity generation will reduce Wallington's carbon footprint by more than ten per cent."
She added that Npower is advising residents to install smart meters in order to access electricity consumption readings every six seconds and enable them to compare energy practices.
The government plans to organise a nationwide roll-out of smart meters by 2020.
