Energy bills are increasing at a rapid rate, with consultancies forecasting that they could hit £4,266 a year per household in January.
After assessing current consumer habits, retail experts are now reporting households are purchasing insulation to warm their homes and save money on bills.
Latest data, provided by online marketplace OnBuy.com, shows week-on-week sales of household insulation is up 1238%.
According to Northern Energy, poor wall insulation accounts for 35-45% of heat lost in the home - resulting in lost energy and wasted money.
Elsewhere, experts believe around 25% of a home's heat is lost through lofts and attics, a loss that can be mitigated against with good insulation.
Liam Tickner, home and garden category manager at OnBuy, said: “The cost of living crisis is affecting people right across the nation.
“With energy bills set to hit over £4,000 a year in January, and with the price of everyday expenses increasing, we are seeing people looking to save money.
“A poorly insulated house or flat can lead to lots of wasted money. Ahead of autumn and winter, we are seeing households purchasing insulation in an effort to save on bills”.
