How to insulate your loft

Without proper insulation, as much as 50% of your heating could disappear straight through your walls and roof. And leaking heat means leaking money.

Surprisingly quick and easy to install, loft insulation is one of the most effective step you can take to make your home more energy-efficient and bring down your bills. In fact, if every UK household fitted it to the recommended thickness, it would save enough energy to heat 750,000 homes each year.
