To show the difference R10 makes we tested two types of heat insulation seperately

Normal Heat Insulation System & R10 Heat Insulation System

2022 Update:

Data from the Department for Business, Energy & Industrial Strategy (BEIS) suggests that electricity prices per kwh will reach on average 28 p/kWh in 2022. Using these numbers, with R10 Insulation this equates to £371.56 per year, or £30.96 per month. Without R10 insulation, this equates to a whopping £1,228.92 per year, or £102.41 per month.

For 2022, this is a saving of £71.45 per month, or £857.36 per year.
