News: Home insulation: How can it cut energy bills?
Households that insulate their homes could save an average of £555 on their annual fuel bills, according to the Energy Savings Trust.
The government is capping energy costs, with a typical household expected to pay about £2,500 annually, for the next two years.
Insulation is the process of trapping heat inside a property, usually by covering areas exposed to the outside, such as roofs, floors and walls.
Without it, indoor temperatures are difficult to maintain, and homes can lose up to 45% of their heat, according to the Energy Savings Trust.
